英文参考资料The enterprise information system is the enterprise information material base, enterprise information system construction good and the badness, regarding enhances the enterprise the economic efficiency to have the very important function. The establishment enterprise information system, carries on the management in enterprise's each level and each function domain to enterprise's management decision-making activity, is enhances the enterprise competitive ability the important way. The level each kind of enterprise information system construction, specially faces the supervisory work the management information information system construction, has become the enterprise information advancement the main part.The enterprise information system establishment mainly is in the management information system (MIS) in the foundation, uses the computer-aided design and makes (CAD/CAM), establishes the computer integration manufacture system (CIMS). In development decision-making support program (DSS) in the foundation, and controls through the man-machine dialogue action program, from material demand plan (MRP), manufacture resources plan (MRPII) and enterprise resources plan (ERP). Also has a volume of development, the production and the material object retails to a body punctual production (JIT), unceasingly eliminates the waste the fine production (LP), supplies in the chain management the fast response and the agile manufacture (AM), non- pollution clean production and green manufacture, as well as through network coordination design and production parallel project (CE) and so on. These information society new production methods merge into one organic whole the information technology revolution and the management progress, cause the enterprise to win in the aspects the competitive advantage, these information systems applications also cause the enterprise to produce, the business data, in the enterprise policy-maker three levels in the enterprise realize the information. Under introduced several kind of main enterprises information system management information system (Management Information System, MIS), is by the artificial leadership, using the computer hardware, software, the network corresponds these equipment and other office equipments carries on the information the collection, the transmission, the processing, the storage, the renewal and the maintenance achieved the enterprise strategy competes superior, enhances the benefit and the efficiency goal, supports the enterprise the high level decision-making, the intermediate deck control and the basic unit operation integration man-machine system. MIS is the superintendent provides the report, provides the enterprise the recent situation as well as the historic record. This system main localization is aims at in the enterprise, for management function and so on level plan, control and decision-making serves, generally provides the data by the lower level handling of traffic system. MIS will be able the actual enterprise's each kind of movement situation, and using the past historical data forecast future, embarks the assistance enterprise from the enterprise overall situation angle to carry on the decision-making, used the message control enterprise the behavior, helped the enterprise to achieve its plan goal. The present management information system is, "Antony which design and the deduction comes according to renowned" Antony the model "model" is the modern management information system founder. In 1965, Antony (Anthony) and so on the business management studied the expert through 15 years massive practices to the European and American system modelling enterprise to observe and to confirm, established the manufacturing industry management management service flow and its the information system skeleton theory, namely renowned "Antony model", this theory thought the management management service activity, namely the business management system mightdivide into the strategic plan, the tactical decision-making and the service decision-making 3 levels (1) the strategic plan level (Strategic Planning Layer, SPL): For the highest management level, is refers to such as the enterprise to organize the goal the hypothesis and the change, for realizes plan, the plan, the budget process and so on resources policy which this goal adopts. (2) tactic decision-making strata (Tactics Decision Layer, TDL): Also is called the management control level, for the middle management level, is for the realization business goal, enables the enterprise effectively to obtain and the use resources concrete application process. (3) handling of traffic level (Business Treatment Layer, BTL): Also is called the operating control level, for the lower level management level, is for determined some specific service can the entire process which effectively, highly effective carries out. Antony the management information system definition will be: "can nimbly utilize the information technology, in the systematized transmission, the memory, the exchange enterprise the exterior information, thus forms either support enterprise's management or service system". Along with the time progress, the information technology and the management science development, the business management information system function already foundation unceasingly performed in "Antony in the model" to expand and the consummation, at this point has developed for the 5th generation based on the electronic accounting machine network technology and the electronic commerce technology modern management information system. The management information can support the strategic plan level, the management control level, the operation control level three levels. These three levels are the enterprise are high, center, the low three levels administrative personnel, it has reflected regarding the enterprise in the marketing function, the manufacture function, the information service function, human resources management function each level the and so on management function, financial control function comprehensive support. The management information system is based on the information technology the challenge, the organization and the management explanation which proposed to the environment. The administrative personnel wants to face the objective environment regarding enterprise's challenge, first in under the management information technology support, must have a management information system. The management information system utilized has been advanced, the management, the information processing technology aims at the environment the challenge, it actually was along with the information technology unceasingly front then advance, changed the management information along with the environment unceasing diastrophism to be able to support the strategic plan level, the management control level, the operation control level three levels. Each level regarding management information specific request including following several aspects: (1) the information origin is different. Management, namely strategic plan level administrative personnel, not only needs the enterprise interior the information, moreover must know the external environment the information. Because must formulate the enterprise developmental strategy plan, must understand the competitor the information, the partner information, government all policies, the laws and regulations change information. But the enterprise interior operation level personnel needs the information originates mainly is the internal information. (2) the information comprehensive degree is different. High level administrative personnel comprehensive nature high, each aspect requests the information content is big. But regarding the concrete operation control personnel, only is responsible for the partial management the concrete work, the request information synthesis degree very is low. (3) the information processing method is different. Because the high level personnel involves the policy-making question many and varied, the different question needs the different processing method process information, therefore regarding the strategic plan level said the processing the method is indefinite. But said regarding the operation control level personnel that, the processing method is definite. For instance, keeps in stock the stock information which the personnel processes nothing but is: How many goodsinside the storehouse has received? How much materials sent out? How much materials has received? Then carries on correspondingly counts splits out the report form, these all are the extremely fixed processing methods. Information provides which to the different administrative personnel, whether is suitable for the different administrative personnel's need, this is a question which the management information system design needs to solve. Therefore should aim at differently needs to process the different information content, uses the different processing method to satisfy each level the request. The management information system (M I S) not only supports the underlying bed administrative personnel, moreover may support the intermediate deck personnel's management control, for high level also can provide certain information. The management information system constitutes by four parts: Information source, information processor, information user and information superintendent. The information source is the information production place; Information processor burden duty and so on information transmission, processing, preservation; The information user is the information user, carries on the decision-making using the information; The information superintendent is responsible for the information system the design, the realization and the maintenance. The management information system is generally regarded as a pyramid shape the structure, divides into from the first floor handling of traffic to the operating control, the management control, the topmost story strategic planning. The most basic unit greatly processes the numerous and diverse business information and the condition information constitution by the duty. The level more upward, business processes the scope is smaller, in view of also is quite special and the non- structure question. A organization's management information system decomposable is four major components: 1st, EDPS are partial, mainly completes the data the collection, the input, the database management, the inquiry, the fundamental operation, the daily report form output and so on. 2nd, the analysis part, mainly above the EDPS foundation, the logarithm according to carries on the deep processing, like utilizes each kind of management model, the quantitative analysis method, the sequenced method, the operations research method and so on carries on the analysis to organization's production operating condition. 3rd, the decision-making are partial, the MIS policy-making model is restricted in solves the structure management decision-making problem primarily, its policy-making result must provide a best policy-making plan for the high level superintendent. 4th, database partial, mainly completes function and so on data file storage, organization, backup, the database is the management information system core are partial. In addition, a organization's management information system may act according to manages the function the different division for the longitudinal subsystem. The main subsystem includes: 1st, stock management subsystem, function including to stock control, stock account management, ordering plan formulation and warehouse own management and so on. 2nd, production management subsystem, function including material demand plan formulation, productive plan arrangement, production scheduling and daily production data management analysis and so on. 3rd, the personnel management subsystem, the function including personnel's records management, the personnel checks attendance the situation management, the personnel each kind of insurance fund management and the personnel trains the plan the system to grade. 4th, the financial control subsystem, the function including a financial account item management, the production cost of operation management, the financial condition analysis and the financial plan system grades. 5th, sales management subsystem, function including sales plan formulation, sales condition analysis, customer information management and sales contract management and so on. 6th, the policy-making support subsystem, the function manages strategic including the enterprise the formulation, the enterprise resources assignment and so on. The system function subsystem division different has the difference because of enterprise's production management characteristic, the above six functions subsystems common enterprise all has, moreover the above each sub- system may carry on a thinner levelthe division, here we no longer give the detailed explanation. The management information system assistance completes the enterprise daily structure information processing task, generally thought MIS the primary mission has the following several aspects: 1st, carries on the strict management to the foundation data, the request measurement tool standardization, the procedure and the method correct use, causes the information circulation channel to be smooth. Some point must be clear about when goes in is a trash, comes out also is trash ", must guarantee the information the accuracy, the uniformity. 2nd, determination information processing process standardization, unified data and report form standard form, in order to establishes a centralism unified database. 3rd, highly effective feeble-mindedly completes the daily business to process the service, the optimization assigns each kind of resources, including manpower, physical resource, financial resource and so on. 4th, the full use had the resources, including present and the historical data message and so on, utilizes each kind of management model, the logarithm according to carries on processing processing, supports the management and the policy-making work, in order to realization organization goal.企业信息系统是企业信息化的物质基础，企业信息系统建设的好与坏，对于提高企业的经济效益有至关重要的作用。

生物科学论文中英文资料外文翻译文献
生物科学论文中英文资料外文翻译文献Carotenoid Biosynthetic Pathway in the Citrus Genus: Number of Copies and Phylogenetic Diversity of Seven GeneThe first objective of this paper was to analyze the potential role of allelic variability of carotenoid biosynthetic genes in the interspecifi diversity in carotenoid composition of Citrus juices. The second objective was to determine the number of copies for each of these genes. Seven carotenoid biosynthetic genes were analyzed using restriction fragment length polymorphism (RFLP) and simple sequence repeats (SSR) markers. RFLP analyses were performed with the genomic DNA obtained from 25 Citrus genotypes using several restriction enzymes. cDNA fragments of Psy, Pds, Zds, Lcyb, Lcy-e, Hy-b, and Zep genes labeled with [R-32P]dCTP were used as probes. For SSR analyses, two primer pairs amplifying two SSR sequences identified from expressed sequence tags (ESTs) of Lcy-b and Hy-b genes were designed. The number of copies of the seven genes ranged from one for Lcy-b to three for Zds. The genetic diversity revealed by RFLP and SSR profiles was in agreement with the genetic diversity obtained from neutral molecμLar markers. Genetic interpretation of RFLP and SSR profiles of four genes (Psy1, Pds1, Lcy-b, and Lcy-e1) enabled us to make inferences on the phylogenetic origin of alleles for the major commercial citrus species. Moreover, the resμLts of our analyses suggest that the allelic diversity observed at the locus of both of lycopene cyclase genes, Lcy-b and Lcy-e1, is associated with interspecific diversity in carotenoid accumμLation in Citrus. The interspecific differences in carotenoid contents previously reported to be associated withother key steps catalyzed by PSY, HY-b, and ZEP were not linked to specific alleles at the corresponding loci.KEYWORDS: Citrus; carotenoids; biosynthetic genes; allelic variability; phylogeny INTRODUCTIONCarotenoids are pigments common to all photosynthetic organisms. In pigment-protein complexes, they act as light sensors for photosynthesis but also prevent photo-oxidat ion induced by too strong light intensities. In horticμLtural crops, they play a major role in fruit, root, or tuber coloration and in nutritional quality. Indeed some of these micronutrients are precursors of vitamin A, an essential component of human and animal diets. Carotenoids may also play a role in chronic disease prevention (such as certain cancers), probably due to their antioxidant properties. The carotenoid biosynthetic pathway is now well established. Carotenoids are synthesized in plastids by nuclear-encoded enzymes. The immediate precursor of carotenoids (and also of gibberellins, plastoquinone, chlorophylls,phylloquinones, and tocopherols) is geranylgeranyl diphosphate (GGPP). In light-grown plants, GGPP is mainly derivedcarotenoid, 15-cis-phytoene. Phytoene undergoes four desaturation reactions catalyzed by two enzymes, phytoene desaturase (PDS) and β-carotene desaturase (ZDS), which convert phytoene into the red-colored poly-cis-lycopene. Recently, Isaacson et al. and Park et al. isolated from tomato and Arabidopsis thaliana, respectively, the genes that encode the carotenoid isomerase (CRTISO) which, in turn, catalyzes the isomerization of poly-cis-carotenoids into all-trans-carotenoids. CRTISO acts on prolycopene to form all-trans lycopene, which undergoes cyclization reactions. Cyclization of lycopene is abranching point: one branch leads to β-carotene (β, β-carotene) and the other toα-carotene (β, ε-carotene). Lycopene β-cyclase (LCY-b) then converts lycopene intoβ-carotene in two steps, whereas the formation of α-carotene requires the action of two enzymes, lycopene ε- cyclase (LCY-e) and lycopene β-cyclase (LCY-b). α- carotene is converted into lutein by hydroxylations catalyzed by ε-carotene hydroxylase (HY-e) andβ-carotene hydroxylase (HY-b). Other xanthophylls are produced fromβ-carotene with hydroxylation reactions catalyzed by HY-b and epoxydation catalyzed by zeaxanthin epoxidase (ZEP). Most of the carotenoid biosynthetic genes have been cloned and sequenced in Citrus varieties . However, our knowledge of the complex regμLation of carotenoid biosynthesis in Citrus fruit is still limited. We need further information on the number of copies of these genes and on their allelic diversity in Citrus because these can influence carotenoid composition within the Citrus genus.Citrus fruit are among the richest sources of carotenoids. The fruit generally display a complex carotenoid structure, and 115 different carotenoids have been identified in Citrus fruit. The carotenoid richness of Citrus flesh depends on environmental conditions, particμLarly on growing conditions and on geogr aphical origin . However the main factor influencing variability of caro tenoid quality in juice has been shown to be genetic diversity. Kato et al. showed that mandarin and orange juices accumμLated high levels of β-cryptoxanthin and violaxanthin, respectively, whereas mature lemon accumμLated extremely low levels of carotenoids. Goodner et al. demonstrated that mandarins, oranges, and their hybrids coμLd be clearly distinguished by theirβ-cryptoxanthin contents. Juices of red grapefruit contained two major carotenoids: lycopene and β-carotene. More recently, we conducted a broad study on the organization of the variability of carotenoid contents in different cμLtivated Citrus species in relation with the biosynthetic pathway . Qualitative analysis of presence or absence of the different compounds revealed three main clusters: (1) mandarins, sweet oranges, and sour oranges;(2) citrons, lemons, and limes; (3) pummelos and grapefruit. Our study also enabled identification of key steps in the diversification of the carotenoid profile. Synthesis of phytoene appeared as a limiti ng step for acid Citrus, while formation of β-carotene and R-carotene from lycopene were dramatically limited in cluster 3 (pummelos and grapefruit). Only varieties in cluster 1 were able to produce violaxanthin. In the same study , we concluded that there was a very strong correlation between the classification of Citrus species based on the presence or absence of carotenoids (below,this classification is also referred to as the organization of carotenoid diversity) and genetic diversity evaluated with bi ochemical or molecμLar markers such as isozymes or randomLy amplified polymorphic DNA (RAPD). We also concluded that, at the interspecific level, the organization of the diversity of carotenoid composition was linked to the global evolution process of cμLt ivated Citrus rather than to more recent mutation events or human selection processes. Indeed, at interspecific level, a correlation between phenotypic variability and genetic diversity is common and is generally associated with generalized gametic is common and is generally associated with generalized gametic disequilibrium resμLting from the history of cμLtivated Citrus. Thus from numerical taxonomy based on morphologicaltraits or from analysis of molecμLar markers , all authors agreed on the existence o f three basic taxa (C. reticμLata, mandarins; C. medica, citrons; and C. maxima, pummelos) whose differentiation was the resμLt of allopatric evolution. All other cμLtivated Citrus specie s (C. sinensis, sweet oranges; C. aurantium, sour oranges;C. paradi si, grapefruit; and C. limon, lemons) resμLted from hybridization events within this basic pool except for C. aurantifolia, which may be a hybrid between C. medica and C. micrantha .Our p revious resμLts and data on Citrus evolution lead us to propose the hypothesis that the allelic variability supporting the organization of carotenoid diversity at interspecific level preceded events that resμLted in the creation of secondary species. Such molecμLar variability may have two different effects: on the one hand, non-silent substitutions in coding region affect the specific activity of corresponding enzymes of the biosynthetic pathway, and on the other hand, variations in untranslated regions affect transcriptional or post-transcriptional mechanisms.There is no available data on the allelic diversity of Citrus genes of the carotenoid biosynthetic pathway. The objective of this paper was to test the hypothesis that allelic variability of these genes partially determines phenotypic variability at the interspecific level. For this purpose, we analyzed the RFLPs around seven genes of the biosynthetic pathway of carotenoids (Psy, Pds, Zds, Lcy-b, Lcy-e, Hy-b, Zep) and the polymorphism of two SSR sequences found in Lcy-b and Hy-b genes in a representative set of varieties of the Citrus genus already analyzed for carotenoid constitution. Our study aimed to answer the following questions: (a) are those genes mono- or mμLtilocus, (b) is the polymorphism revealed by RFLP and SSR markers inagreement with the general histor y of cμLtivated Citrus thus permitting inferences about the phylogenetic origin of genes of the secondary species, and (c) is this polymorphism associated with phenotypic (carotenoid compound) variations.RESΜLTS AND DISCUSSIONGlobal Diversity of the Genotype Sample Observed by RFLP Analysis. RFLP analyses were performed using probes defined from expressed sequences of seven major genes of the carotenoid biosynthetic pathway . One or two restriction enzymes were used for each gene. None of these enzymes cut the cDNA probe sequence except HindIII for the Lcy-e gene. Intronic sequences and restriction sites on genomic sequences werescreened with PCR amplification using genomic DNA as template and with digestion of PCR products. The resμLts indicated the absence of an intronic sequence for Psy and Lcy-b fragments. The absence of intron in these two fragments was checked by cloning and sequencing corresponding genomic sequences (data not shown). Conversely, we found introns in Pds, Zds, Hy-b, Zep, and Lcy-e genomic sequences corresponding to RFLP probes. EcoRV did not cut the genomic sequences of Pds, Zds, Hy-b, Zep, and Lcy-e. In the same way, no BamHI restriction site was found in the genomic sequences of Pds, Zds, and Hy-b. Data relative to the diversity observed for the different genes are presented in Table 4. A total of 58 fragments were identified, six of them being monomorphic (present in all individuals). In the limited sample of the three basic taxa, only eight bands out of 58 coμLd not be observed. In the basic taxa, the mean number of bands per genotype observed was 24.7, 24.7, and 17 for C. reticμLata, C. maxima, and C. medica, respectively. It varies from28 (C. limettioides) to 36 (C. aurantium) for the secondary species. The mean number of RFLP bands per individual was lower for basic taxa than for the group of secondary species. This resμLt indicates that secondary species are much more heterozygous than the basic ones for these genes, which is logical if we assume that the secondary species arise from hybridizations between the three basic taxa. Moreover C. medica appears to be the least heterozygous taxon for RFLP around the genes of the carotenoid biosynthetic pathway, as already shown with isozymes, RAPD, and SSR markers.The two lemons were close to the acid Citrus cluster and the three sour oranges close to the mandarins/sweet oranges cluster. This organization of genetic diversity based on the RFLP profiles obtained with seven genes of the carotenoid pathway is very similar to that previously obtained with neutral molecμLar markers such as genomic SSR as well as the organization obtained with qualitative carotenoid compositions. All these resμLts suggest that the observed RFLP and SSR fragments are good phylogenetic markers. It seems consistent with our basic hypothesis that major differentiation in the genes involved in the carotenoid biosynthetic pathway preceded the creation of the secondary hybrid species and thus that the allelic structure of these hybrid species can be reconstructed from alleles observed in the three basic taxa.Gene by Gene Analysis: The Psy Gene. For the Psy probe combined with EcoRV or BamHI restriction enzymes, five bands were identified for the two enzymes, and two to three bands were observed for each genotype. One of these bands was present in all individuals. There was no restriction site in the probe sequence. These resμLts lead us to believe that Psy is present at two loci,one where no polymorphism was found with the restriction enzymes used, and one that displayed polymorphism. The number of different profiles observed was six and four with EcoRV and BamHI, respectively, for a total of 10 different profiles among the 25 individuals .Two Psy genes have also been found in tomato, tobacco, maize, and rice . Conversely, only one Psy gene has been found in Arabidopsis thaliana and in pepper (Capsicum annuum), which also accumμLates carotenoids in fruit. According to Bartley and Scolnik, Psy1 was expressed in tomato fruit chromoplasts, while Psy2 was specific to leaf tissue. In the same way, in Poaceae (maize, rice), Gallagher et al. found that Psy gene was duplicated and that Psy1 and notPsy2 transcripts in endosperm correlated with endosperm carotenoid accumμLation. These resμLts underline the role of gene duplication and the importance of tissue-specific phytoene synthase in the regμLation of carotenoid accumμLation.All the polymorphic bands were present in the sample of the basic taxon genomes. Assuming the hypothesis that all these bands describe the polymorphism at the same locus for the Psy gene, we can conclude that we found allelic differentiation between the three basic taxa with three alleles for C. reticμLata, four for C. maxima, and one for C. medica.The alleles observed for the basic taxa then enabled us to determine the genotypes of all the other species. The presumed genotypes for the Psy polymorphic locus are given in Table 7. Sweet oranges and grapefruit were heterozygous with one mandarin and one pummelo allele. Sour oranges were heterozygous; they shared the same mandarin allele with sweet oranges but had a different pummelo allele. Clementine was heterozygous with two mandarin alleles; one shared with sweetoranges and one with “Willow leaf” mandarin. “Meyer” lemon was heterozygous, with the mandarin allele also found in sweet oranges, and the citron allele. “Eureka”lemon was also heterozygous with the same pummelo allele as sour oranges and the citron allele. The other acid Citrus were homozygous for the citron allele.The Pds Gen. For the Pds probe combined with EcoRV, six different fragments were observed. One was common to all individuals. The number of fragments per individual was two or three. ResμLts for Pds led us to believe that this gene is present at two loci, one where no polymorphism was found with EcoRV restriction, and one displaying polymorphism. Conversely, studies on Arabidopsis, tomato, maize, and rice showed that Pds was a single copy gene. However, a previous study on Citrus suggests that Pds is present as a low-copy gene family in the Citrus genome, which is in agreement with our findings.The Zds Gene. The Zds profiles were complex. Nine and five fragments were observed with EcoRV and BamHI restriction, respectively. For both enzymes, one fragment was common to all individuals. The number of fragments per individual ranged from two to six for EcoRV and three to five for BamHI. There was no restriction site in the probe sequence. It can be assumed that several copies (at least three) of the Zds gene are present in the Citrus genome with polymorphism for at least two of them. In Arabidopsis, maize, and rice, like Pds, Zds was a single-copy gene .In these conditions and in the absence of analysis of controlled progenies, we are unable to conduct genetic analysis of profiles. However it appears that some bands differentiated the basic taxa: one for mandarins, one for pummelos, and one for citrons with EcoRV restriction and one for pummelos and onefor citrons with BamHI restriction. Two bands out of the nine obtained with EcoRV were not observed in the samples of basic taxa. One was rare and only observed in “Rangpur” lime. The other was found in sour oranges, “V olkamer” lemon,and “Palestine sweet” lime suggesting a common ancestor for these three genotypes.This is in agreement with the assumption of Nicolosi et al. that “V olkamer” lemon resμLts from a complex hybrid combination with C. aurantium as one parent. It will be necessary to extend the analysis of the basic taxa to conclude whether these specific bands are present in the diversity of these taxa or resμLt from mutations after the formation of the secondary species.The Lcy-b Gene with RFLP Analysis.After restriction with EcoRV and hybridization with the Lcy-b probe, we obtained simple profiles with a total of four fragments. One to two fragments were observed for each individual, and seven profiles were differentiated among the 25 genotypes. These resμLts provide evidence that Lcy-b is present at a single locus in the haploid Citrus genome. Two lycopene β-cyclases encoded by two genes have been identified in tomato. The B gene encoded a novel type of lycopene β-cyclase whose sequence was similar to capsanthin-capsorubin synthase. The B gene expressed at a high level in βmutants was responsible for strong accumμLation ofβ-carotene in fruit, while in wild-type tomatoes, B was expressed at a low level.The Lcy-b Gene with SSR Analysis. Four bands were detected at locus 1210 (Lcy-b gene). One or two bands were detected per variety confirming that this gene is mono locus. Six different profiles were observed among the 25 genotypes. As with RFLPanalysis, no intrataxon molecμLar polymorphism was found within C. Paradisi, C. Sinensis, and C. Aurantium.Taken together, the information obtained from RFLP and SSR analyses enabled us to identify a complete differentiation among the three basic taxon samples. Each of these taxons displayed two alleles for the analyzed sample. An additional allele was identified for “Mexican” l ime. The profiles for all secondary species can be reconstructed from these alleles. Deduced genetic structure is given in. Sweet oranges and clementine were heterozygous with one mandarin and one pummelo allele. Sour oranges were also heterozygous sharing the same mandarin allele as sweet oranges but with another pummelo allele. Grapefruit were heterozygous with two pummelo alleles. All the acid secondary species were heterozygous, having one allele from citrons and the other one from mandarins except for “Mexican” lime, which had a specific allele.柑桔属类胡萝卜素生物合成途径中七个基因拷贝数目及遗传多样性的分析摘要：本文的首要目标是分析类胡萝卜素生物合成相关等位基因在发生变异柑橘属类胡萝卜素组分种间差异的潜在作用；第二个目标是确定这些基因的拷贝数。

What Is Translation?Linguistic view on translation:Translation is “the replacement of textual material in one language (source language) by equivalent textual material in another language (target language). ”(Catford, 1965:20)Translating consists in reproducing in the receptor language the closest natural equivalent of the source-language message, first in terms of meaning and secondly in terms of style. (Nida & Taber 1969:12)所谓翻译，是指在译语中用最贴切而又自然的对等语再现原文的信息，首先在语义上，其次在文体上。
(E. A 奈达, 1969)Communicative views on translation:This approach views translation as a communicative process which takes place within a social context. The translator attempts to produce the same effect on the target language readers as was produced by the original on the source language readers. (Newmark, 1982:22) 翻译是一种跨文化的信息交流与交换的活动，其本质是传播。

中文资料PowerBuilder是著名的数据库应用开发工具生产厂商PowerSoft公司推出的产品（PowerSoft现已被数据库厂商Sybase所收购），它完全按照客户机/服务器体系结构研制设计，在客户机/服务器结构中，它使用在客户机中，作为数据库应用程序的开发工具而存在。
由于PowerBuilder采用了面向对象和可视化技术，提供可视化的应用开发环境，使得我们利用PowerBuilder，可以方便快捷地开发出利用后台服务器中的数据和数据库管理系统的数据库应用程序。
在当前，网络技术迅速发展，随之发展的还有OLE，OCX，跨平台等技术，而在PowerBuilder的最新版PowerBuilder中提供了对这些技术的全面支持。
总之在数据库开发工具领域，PowerBuilder是其中非常优秀的一个，利用它我们可以开发出功能强大的数据库应用程序。
PowerBuilder提供了对目前流行的大多数关系数据库管理系统的支持，由于在PowerBuilder的应用程序中对数据库访问的部分一般采用国际化标准数据库查询语言SQL，使得用PowerBuilder开发的应用程序可以不做修改或者只做少量的修改就可以在不同的后台数据库管理系统上使用。
也就是说用PowerBuilder开发的应用程序是独立于服务器上的数据库管理系统的。
和大多数的windows应用程序一样，PowerBuilder也是事件驱动工作方式。
在这种工作方式中，程序的运行没有固定的流程，程序中的代码也是为各种可能发生的事件编写的，当程序开始运行之后，它就可以接受来自系统，用户或者其它应用程序触发的事件，然后执行相应的事件代码。
事件驱动的工作方式与面向对象技术是紧密相关的。
在PowerBuilder应用程序中，接受发生的事件的往往就是程序界面中的各种可视化对象。
PowerBuilder是一种面向对象的开发工具，各种windows应用程序中常见的窗口、菜单、控件等在PowerBuilder中都是一个个的对象。
在PowerBuilder中我们还可以创建自己的用户对象。
特别要指出的是PowerBuilder提供了对面向对象方法中的各种技术的全面支持，我们可以利用面向对象方法中的对象的封装性、继承性、多态性等特点使得我们开发的应用程序具有极大的可重用性和可扩展性，而这一点正是软件工程中对应用程序所提出的重要目标。
在当前，由于网络技术的发展，许多种不同的操作系统平台在INTERNET网上同时被使用，这对开发的应用程序的跨平台性提出了更高的要求，而PowerBuilder就提供了良好的跨平台性，比如在PowerBuilder 中，利用windows平台开发的各种对象可以方便地应用到UNIX平台中，因为PowerBuilder支持对象的跨平台性。
这样使得把应用程序从一个平台移到另一个平台变得并不复杂。
为了给用户提供各个方面的支持，PowerBuilder具有自己的编程语言POWERSCRIPT，这个语言除了提供基本的流程控制语句，还提供了几百个函数来操纵各种对象和提供诸如DDE，OLE等方面的支持。
此外我们还可以定义自己的函数，处理特定的事件。
学习PowerBuilder时相当一部分的时间就是用来了解和熟悉PowerBuilder提供的各种函数。
PowerBuilder一个很大的特点就是提出了数据窗口对象的概念。
数据窗口对象也是PowerBuilder中的一种对象类型，与其它对象不同的是数据窗口对象是专门为了访问后台的数据库服务的，在数据窗口对象中我们定义了数据的来源和数据的显示风格，这样在应用程序中我们就可以把精力完全放在程序的运行流程控制上，而不用关心具体数据的来源，因为我们在数据窗口对象中已经定义好了数据的来源。
如果需要使用数据库中不同的数据也只要对数据窗口对象进行修改就可以了。
特别要指出的是PowerBuilder在数据窗口对象中提供了丰富的数据显示方式，可以满足各种不同的需要。
在PowerBuilder较新的版本中提供了基础类库PFC，它为应用程序的开发提供了许多可重用的预定义类和对象，利用基本类库PFC可以快速开发出高质量重用性好的应用程序。
真正发挥面向对象编程的巨大威力。
最后要指出的是PowerBuilder有三个不同的版本，分别为DESKTOP 型，PROFESSIONAL型，和ENTERPRISE型，DESKTOP型是为个人使用的桌面型应用程序，在这里可以利用PowerBuilder内置的数据库管理系统SYBASE SQL ANYWHERE来创建和使用本地数据库，为个人的应用服务；PROFESSIONAL型的PowerBuilder最重要的一点就是提供了对MICROSOFT ODBC（数据库标准连接接口）的支持，在PROFESSIONAL版本中我们就可以使用PowerBuilder的继承，多态等绝大多数特性；在ENTERPRISE版本中最重要的一点就是提供了对开发大型的数据库应用程序的全面的支持，提供了开发大型应用程序的许多辅助的工具，比如C++ CLASS BUILDER等。
数据库前端开发工具与后台数据库管理系统的连接方式是一个很重要的课题。
PowerBuilder提供了两种访问后台数据库的方式，一种是通过ODBC标准接口的方式，第二种是通过专用的接口与后台的数据库相连。
ODBC的中文名字是开放式数据库连接，它是微软公司提出的数据库连接标准，使用ODBC方式连接数据库的第一步是创建数据源，比如我们可以利用windows下控制面板中的“32 BIT ODBC”选项来创建驱动某种数据库的数据源，创建好数据源之后，我们就可以在本地计算机中利用定义好的数据源存取后台数据库中的数据了。
我们还可以通过专用接口同后台的数据库相连，由于专用接口是针对特定的后台数据库管理系统而设计，因此这种方式存取数据的速度要比采用ODBC方式存取数据的速度要快一些，如果我们的应用程序只是针对特定类型的后台数据库，当然是采用专用接口访问后台数据更快一些。
英文资料PowerBuilder is a popular database application development tool manufacturer which is called PowerSoft introduced product （PowerSoft has been purchased by the database manufacturer called Sybase）, it entirely designed in accordance with the client / server architecture, in the client / server architecture, it uses the client, as a database application development tool to exist. Because of using object-oriented and visualization technologies, providing visual application development environment in PowerBuilder, allows us to be developing data and database management system database applications in the background server easily and quickly.At present, network technology is developing rapidly, with the development of the OLE, OCX, cross-platform technology, and in the latest version of PowerBuilder provides the full support of these technologies. In a word, in the database development tools, PowerBuilder is a very good product of them, we can use it to develop powerful database applications.PowerBuilder provides support in most of the current popular relation database management systems, because in PowerBuilder applications for database access part of the general international standard database query language SQL, makes using PowerBuilder development of the application can be used in different background of database management systems without revision or do a small amount of revision. That is to say, with PowerBuilder development of the application server is independent of the database management system.As the most of the windows application procedures, PowerBuilder is also event driven of the method to work. In this work method, program for the operation has no fixed processes, the code in the program is also possible programmed for the preparation of the events, when the program began running, it can be accepted the events that are from the system, users or other applications trigger, and then execute the relevant code. Event driven methods of work isclosely related to the object-oriented technology. In the PowerBuilder application, acceptance of the events is often the various visual interface object in the program.PowerBuilder is an object-oriented development tool, various common application windows, menus, and other controls in Windows are one and one targets in PowerBuilder. We can also create own user object in PowerBuilder. We should point out that the PowerBuilder provides object-oriented method of comprehensive technical support, we can make use of object-oriented methods in the object of encapsulation, inheritance, polymorphism, and other features make the our development applications have great reusability and scalability, which is on the application in the process of the important goals in software engineering.At present, due to the development of network technology, and many different types of operating system platforms are using on the internet at the same time, this is a higher request for the development of the cross-platform application, and PowerBuilder provides a good cross-platform, for example, in PowerBuilder, using Windows platform for the development of all kinds of objects can be easily applied to the UNIX platform, because PowerBuilder supports cross-platform object. This allows the applications from one platform to another platform to become not complicated.In order to provide the user all aspects of supports, PowerBuilder has its own programming language which is called power script, in addition to providing the basic flow control statements, but also to provide hundreds of functions to manipulate objects and all kinds of information supports such as DDE, OLE, and other aspects in this language . Furthermore, we can also define our own functions and deal with specific incidents. When we learn PowerBuilder, a part of the time is to understand and familiar with the functions in PowerBuilder.In PowerBuilder, a great feature is to propose the concept of data window. Data window object is one of the objects in PowerBuilder, it is different from other objects, because data window isspecifically targeted to visit background database services, in the data window, we define data sources and data display style, so that we will be able to concentrate fully on the operation of process control procedures in application procedures, and couldn’t concern about data sources, because we have been well defined data sources in the data window. If you need to use different data in the database as long as the data is revised target window on it. In particular, we should point out that the PowerBuilder provides a wealth of data display mode in data window object, and this can meet a variety of needs.In a new version of PowerBuilder, it provides a foundation class library PFC, it provides many reusable predefined classes and objects for application procedures of development, using the basic class library PFC can enable the rapid development of high-quality reuse of good application procedures. It is really rolling power of object-oriented programming.Finally we should point out that the there are three different versions: desktop type, professional type, and enterprise type. Desktop type is for personal using of the desktop applications, where you can use the built-in PowerBuilder database management system Sybase SQL anywhere to create and use of local databases, the application for personal services; professional type of PowerBuilder most important point is to provide the support of Microsoft ODBC （database connectivity standard interface）,in professional version of PowerBuilder, we can use the inheritance, polymorphism and more features; in the enterprise versions of the most important point is to provide for the development of large-scale database applications and comprehensive support, the development of large-scale applications of the many auxiliary tools, such as C++, class builder and so on.Database front-end development tool and the background database management system in a way is a very important issue. PowerBuilder provides two ways to visit the background database, the one way is standard interface through ODBC, and the second is through adedicated interface with the database linked to the background.ODBC is called Open Database Connectivity in Chinese, it is the database connectivity standards which is proposed by Microsoft, the use of ODBC database connectivity of the first step is creating data sources, for example, we can use windows control panel under the "32 BIT ODBC" election of the drive to create a database of data sources, after finishing creating data sources, we will be able to use computers in the local definition of good background data source to access to the data in the database.We can also link to the background through a dedicated interface with the database, because dedicated interface is designed against the background of a specific database management system, by this way to access to data faster than using ODBC way to access to data. If our application is only for specific types of background database, of course, using a special interface to background information will be more faster.。
