材料四要素

材料科学四要素的内涵和关系摘要:材料科学四要素的提出,在貌似不相关的材料之间找到了共同点,反映了材料科学与工程研究中的共性问题。
这里综述了材料科学四要素的内涵,并具体讨论了它们相互之间的关系与作用。
关键字:材料科学,四要素,共同点,内涵,关系与作用Connotation and relationship of four elementsin materials scienceAbstract:There find common ground in the material that seemingly do not related to eachother with the four elements of materials science that reflects the common problems in materials science and engineering research are proposed. Here reviewed the connotation of the four elements of materials science, And the relationship between them are discussed in detail.Key words: materials science,the four elements,common ground,connotation,relationship and effect材料是人类赖以生存和发展的物质基础。
它不仅是人类进化的标志,而且是社会现代化的物质基础与先导。
20世纪70年代人们把信息、材料和能源誉为当代文明的三大支柱。
80年代以高技术群为代表的新技术革命,又把新材料、信息技术和生物技术并列为新技术革命的重要标志。
这主要是因为材料与国民经济建设、国防建设和人民生活密切相关,材料的研究、开发和应用反映着一个国家的科学技术与工业水平。
4,4'-二仲丁氨基二苯基甲烷的合成研究

4,4'-二仲丁氨基二苯甲烷的合成研究邱小勇龚树华罗善锴(深圳市飞扬实业有限公司,广东,深圳,518300)摘要:以4,4’-二氨基二苯基甲烷和丁酮为原料,加氢条件下合成4,4'-二仲丁氨基二苯甲烷。
研究了催化剂,原料摩尔比,反应温度,反应压力,反应时间等不同因素对产物收率的影响。
结果表明:以钯/氢型沸石为催化剂,4,4’-二氨基二苯基甲烷和丁酮的摩尔比为1:5,反应温度135℃左右,反应压力4MPa,反应时间6h,4,4’-二氨基二苯基甲烷转化率可达100%,选择性99.9%。

Abstract:A co-production process for 4-cumylphenol and 2,4-dicumylphenol was developed.The effect of raw material ratios,amount of catalysts,reaction temperature and dosage of re-crystallization solvents on alkylation of phenol andα-methyl-styrene were studied.Approximate 100% phenol conversion,and above 90% yield of 4-cumylphenol and 2,4-dicumylphenol were obtained.The purity of 2,4-dicumylphenol was better than 99% when a two-step re-crystallization with different solvents was employed.The emission of wastewater phenol-containing and other organic pollutants can be completely avoided when a newin-situ neutralization method was utilized for removal of catalysts.The problems of the present production technologies of 4-cumylphenol and 2,4-dicumylphenol,including difficulties in separation and purification, low yields and environmental pollution,could be solved.

Work Cited (10)The Negative Transfer of Mother Tongue on Second Language Acquisition andPedagogical ImplicationI. IntroductionChinese students often complain that it is difficult to learn English well under the influence of naive language. The paper learns from the results achieved from the field of research on negative transfer of mother tongue by our predecessors, tries to make a comparison between English and Chinese languages in the three areas of phonetics ,vocabulary and syntax, introduces that the phenomenon of negative transfer and whose influence on current English teaching in China briefly.II. The definition of transferThe concept of transfer first came from the behavioral psychology. In psychology, transfer means a mental process that the knowledge people have acquired plays a role in a new learning environment. Language transfer is the impact of one language on other language learning. It is a phenomenon that the learners use the rules of naive language to handle the information of target language consciously or unconsciously, which is due to the learners are not familiar with the rules of target language such as the syntax rule in the learning process of a second language or a foreign language. Migration can be mainly divided into two types: one is positive transfer and the other is negative transfer. Positive transfer refers to that the similarities of mother tongue and target language have positive effect on second language learning, which plays an important role for learners to master and use foreign language. Negative transfer is also named mother tongue interference. The mainly causes of negative transfer are some different forms and rules between naive language and target language, however, the learners think they are the same, which is the barrier for learners to master anduse a foreign language.III. The influence of negative transfer of mother tongueA.The negative transfer of phoneticsPhonetics is not only the means of expression, but also the first step to learn a language for the learners. But learners always use the phonetic rules of the mother tongue to replace those of target language, which is the most direct manifestation of interlanguage speech. So we can find out the negative transfer of mother tongue by comparing thedifferences between Chinese pronunciation and English pronunciation.First the transfer is obvious to see because of the differences between English consonants and Chinese initials. In English, there are many of the voices that can‟t be found in Chinese, which leads to the difficulties for Chinese learners to learn it well.For example: There are a set of dental consonants [θ] and [ð] in English. But there is no appropriate sound in Chinese, it is difficult for Chinese learners to read. Even when the learners have mastered the rules of pronunciation, they also make mistakes by using the two similar consonants [s] and [d] to replace [θ] and [ð] unconsciously. So the word of “thank” is often read into “sank” and the word of “those” is read into “dose” by Chinese learners. This kind of transfer causes a lot of problems in listening comprehension.English and Chinese are two different voice systems, so the means of exchanging ideas is also different in the aspect of pronunciation. The means of interchanging ideas for Chinese is the tone. Each syllable in Chinese has its tone to differentiate literal meaning and word meaning. There are four tones in mandarin Chinese. They are YinPing, YangPing, rising tone and falling tone. They are the changes of syllable. The ideographic means of English are intonation and accent. There are six changes in English intonation. They are falling tone, rising tone, fall- rise tone, rise-fall tone, pasteurization tone and drop-plus tone. These changes of intonation can express different meaning and mood.Ex:You may …not go. 你不可以去。
