利用Web of Science检索论文
利用Web of Science检索论文被引用情况的方法与技巧仇琛(复旦大学图书馆上海200433)摘要文章论述了引文索引的特点,并详细介绍了利用Web of Science检索论文被引用情况的方法与技巧。
关键词 Web of Science 论文被引检索方法引文索引是ISI公司出版的著名的期刊文献检索工具,其最大的特点是一反其他检索工具通过主题或分类途径检索文献的常规做法,设置了独特的“引文索引”,即通过前期文献被后来文献的引用情况,来揭示文献之间的相关性及前期文献对后来文献的影响力。
ISI通过它严格的选刊标准和评估程序挑选刊源,从而做到收录的文献能全面覆盖全世界最有影响力的研究成果。
因此引文索引不仅作为一种文献检索工具,而且成为了科研评价的一种依据,科研机构或个人被引文索引收录论文的数量以及这些论文被引用的情况,反映了整个机构或个人的科研水平或学术水平。
ISI公司推出的引文索引的网络版Web of Science,除原有的特点外,还增加了一些基于网络的功能,数据更新快、界面友好,很受读者欢迎。
现在很多高校在教师职称评定或评奖时,都把其发表论文被Web of Science数据库收录的情况、论文在Web of Science数据库中被他人引用的次数以及论文所在期刊的影响因子作为一项重要的评价标准。
因此,为读者检索论文被Web of Science数据库收录和引用情况并出具证明,也成为图书馆经常开展的一项服务。
本文拟对利用Web of Science数据库检索论文被引用情况的方法及技巧进行探讨。
1 检索途径与方法1.1 通过General Search(常规检索)来检索论文被引用情况步骤一、在Web of Science数据库首页选择Full Search,打开Full Search的界面。
步骤二、根据要检索的论文所属的学科、发表的年份,限定检索的数据库和时间范围。
可供选择的数据库有:SCIE、SSCI、A&HCI。
从中国知网上检索、打印论文信息页首页步骤方法

SCI检索号查询以及与DIO&IDS等号的区别
SCI检索号查询,以及与DIO、IDS等号的区别SCI/ISTP和EI论文检索号IDS number和收录号查询方法SCI检索号也即IDS number,一般来讲,同一期出版的刊物上的所有文章的IDS number相同。
查询方法如下:进入ISI Web of Knowledge数据库的Web of Science 分库查询到想要的论文,然后点击文章标题进去查看完整的记录,除了作者摘要等最基本的信息,显示的类型还有出版商、学科类别、IDS号、ISSN 和DOI等。
其中,IDS号也就是我们想要查询的论文检索号。
除了SCI,Web of Science现在包含的引文数据库还有SSCI、A&HCI、CPCI-S和CPCI-SSH以及化学数据库Index Chemicus和Current Chemical Reactions。
特别注意:IDS Number不是SCI收录号。
但我发现很多人都会把它们等同起来。
我在清华大学图书馆的网站上看到这么一段描述:“ISI Web of Knowledge平台上的其它数据库,如ISTP等的文献收录号与SCI相同,也是IDSnumber。
”大错特错也!正确的查询SCI收录号的方法应该是:进入到论文的详细描述页面后,在最底部可以看到“输出记录(Output This Record)”字样,点选下面的“全记录”,然后在右边的“保存”按钮前面可以看到一个下拉菜单,选择“保存为HTML格式”,最后点保存按钮将全记录存在本地计算机上(如下图所示)。
打开这个html文件即可在倒数第三行看到“UT ISI:000262603700008”字段,这里的“ISI:000262603700008”即为SCI论文收录号。
ISTP论文收录号查询方法与SCI相同,只不过得到的字段是“UT ISIP: 000341456802045”的形式。
另见SCI检索方法与技巧。
EI收录号查询方法进入Ei网络版Compendex查询平台Engineering Village 2,按不同检索条件查询到相应的论文之后,进入该条目的详细记录detailed页面,排在首位的Accession number即为当前论文的EI收录号,这也是Compendex数据库给每条记录指定的唯一号码。

Numerical Simulation of Temperature Field in the CyclonePingyang Xiao a and Zhenwei Zhang bSchool of Mechanical Engineering and Automation, Northeastern University, Shenyang, Liaoning, 110004, Chinaa xpypaper@,b zzw1658@Keywords: Separator, Numerical Simulation, Temperature Field.Abstract. This paper mainly focuses on the numerical simulation of temperature field in the cyclone separation. The authors took advantage of RSM turbulence model of software FLUENT to imitate the temperature field. This thesis puts forward the temperature distribution of the cyclone, and figures out that the overall temperature is 373°C. Temperature difference in different region is less than one centigrade degree with the maximum temperature in the cone part and the minimum temperature in inlet tube and cylinder part of the cyclone, what’s more, the temperature is relatively higher near the wall. The air compression can lead the higher temperature in the lower part, so the cone part has the highest temperature. The higher temperature near the wall is caused by the friction between the wall and flow.IntroductionThis paper mainly focuses on the flow field phenomenon of gas-solid separation process in CLT/A type cyclone separator about the potato granules drying system. The simulation is established based on the discrete coupling model, the assumption of which is that the model needs the constant temperature. It is really necessary to simulate the temperature field of CLT/A type cyclone as the temperature of hot air is relatively high in the drying system and the internal temperature conditions can not be determined.Physical modelThe cylindrical volume is relatively large in the cyclone group of CLT/A 8.4×4 type shown in Fig.1. The cyclone separator is divided into four sub-cylinders, which show symmetrical layout and the structure is identical. Therefore the simulation only focuses on the single cylinder.Fig. 1 Structure group graph of Fig. 2 Three-dimensional solid modelCLT / A 8.0 × 4-type cyclone of the CLT / A-type cycloneThe three-dimensional model can be obtained by taking advantage of powerful modeling capabilities of solid surface of UG about CLT/A type cyclone shown in Fig. 2.Finite element modelThe three-dimensional solid model established by UG can be imported into GAMBIT so as to be meshed. Multiple Boolean operations should be carried out on the solid model in order to be facilitated to mesh in GAMBIT, which can lead to the establishment of two entities form. The overall body of Volom1 is consisted of exhaust volute and exhaust pipe. The overall body of Volom2 is consisted of entrance pipe and cone below the cylinder. Then the model is exported in the .step format, and then the model will be imported into GAMBIT. The total model is shown in Fig. 3. Meshing should be conducted in the several parts of model in order to generate the better structured grid. The operations in GAMBIT can be shown as flowing.(1) Establish the auxiliary plane and split the intake pipe with the Split command.(2) The cylinder can be divided into two parts with a plane parallel to Y-axis at Y=2260mm, theupper of which is ring cylinder and the lower part is cylinder.Fig. 3 Physical model of cyclone in GAMBIT Fig. 4 Mesh diagram of CLT / A-type cycloneThe entire cyclone is divided into four parts: intake pipe, outtake pipe, lower half part of the cylinder and the upper half part of the cylinder. The meshing can be imposed on them separately. Meshing is the premise process of numerical simulation and also the discrete process of calculating region. The number of the grid has nothing to do with the final result according to the theory of CFD, and when the intensity of the grid reaches a certain value, it has little effect on the simulation result by continuing encryption [1]. However, in practice, if the mesh is too sparse, it is difficult to describe some detail in the flow field. What’s more, the computing speed can be greatly affected if the number of the meshing is too large. Therefore the number select of the grids can both guarantee the accuracy requirements and avoid excessive consumption of the system resources [2]. This paper adopts the complex grids according to the complexity of the flow field and variability of local feature. The hexahedral grid can be generated, which is the main structure, by taking advantage of Hex/Wedge-type structured grid and Cooper barrel pattern. This kind of grid matches well with the flow field, and is conductive to process of coupling conditions in the numerical simulation region. The meshing can be drawn as Fig. 4.Boundary conditionsThe gas phase can be simplified in order to facilitate solving the multiphase flow inside the cyclone[3].(1) Gas flow is steady-state in cyclone;(2) The gas flow rate is low( generally less than 30m/s), and the gas can be seen as incompressiblefluid;(3) The inlet air flows evenly, and in a fully developed turbulent state;(4) No gas exhausts from the dust exhaust at the bottom of the cyclone.Set the boundary conditions as following:(1) Inlet boundary: the inlet air temperature is 373.15K, and the density is 1.225 kg/m3. The viscosityis 18.1×10-6 . The entrance speed is known, so the inlet boundary is set as the velocity inlet boundary condition. Assuming that the inlet turbulent is developed fully, and the gas inlet velocity is set as 15 m/s evenly distribution throughout the inlet section. The turbulence intensity is set as I and the hydraulic diameter is set as D. Flow Reynolds number is shown as Eq. 1.4e 61.225150.252R 2.5725101810UD ρµ−××===××. (1) Hydraulic diameter is set as Eq. 2. 220.460.2070.2940.460.207HD ab D a b ××===++. (2)Turbulence Intensity is set as Eq. 3. 1/851/8e 0.16(R )100%0.16(2.5710)7.34%I −−=×=××=.(3) (2) Outlet boundary: outlet boundary is set as outflow boundary. Assuming that the flow condition isin fully developed condition, namely the flow situation can be obtained by the pulling of flow field. The air exhaust can be set as the outflow, and the weight of the flow is set as one. The dust exhaust is set as outflow, and the weight of the flow is set as zero.(3) Wall conditions: take the standard wall function, namely the wall has no-slip boundary [4]. Theroughness parameter of wall is set as 0.5.(4) The overlapping circle is set as interface surface, which connects the exhaust pipe and cylinder.Fig. 5 Total temperature fieldNumerical simulation analysisTemperature distribution at various locations in CLT/A type cyclone can be intuitively obtained through numerical simulation shown in the Fig. 5. The entrance temperature is relatively low, and temperature can increase with moving downward along the cone. The value can reach the highest at the bottom of cone. The exhaust temperature can decrease along the exhaust pipe, but is still higher than inlet air temperature. The temperature change reason is shown as following: the air enters the air intake with the number of 100, and the flow can be compressed by centrifugal force caused by the rotation. In addition, the temperature can be increased due to the friction between the flow and wall. The temperature continues to rise owing to the further impact of compression and friction when reaches the cone wall. The final flow will be excluded through the exhaust pipe with some pressure decrease lower than the cone and bigger than the cylinder and inlet, namely the temperature is center. However the temperature change is small, and the left table stays at 3.73e+2 from start to finish shown from the color column. The temperature is about 100℃ in the cyclone with only less than one temperature change. Therefore temperature change is small.Fig. 6 and Fig. 7 respectively show the temperature distribution in Y=0 section about static and total temperature in CLT/A type cyclone separator. The static temperature distribution has the same situation with the total temperature distribution in the Y=0 cross section in the cyclone, and specific temperature change region inside the cyclone can be clear obtained. The temperature of air intake and cylinder is the lowest with the maximum temperature in the cone part, and the temperature of exhaust pipe stays centre. The exhaust pipe temperature can decrease further. Temperature distribution shows a symmetrical situation in both sides of the exhaust pipe or inside the exhaust pipe in cyclone with only little difference near the wall, which shows the vortex shape. The small difference is caused by the local turbulence accompanied by the rotation flow inside cyclone.Fig. 6 Y=0 Static temperature Fig. 7 Y=0 Total temperatureFig. 8 and Fig. 9 respectively show the temperature distribution in X=0 section about static and total temperature in CLT/A type cyclone separator. Temperature distribution of each parts of the X=0 cross section can be seen clearly in the picture. Internal temperature distribution of X=0 section has the same situation with the total temperature distribution in cyclone. The cylinder part below the exhaust pipe has almost the same temperature distribution with the lower cone compared with the section Y=0 with only obvious difference in the position above the air exhaust, the reason for which is that the asymmetry caused the flow’s entrance from the unilateral line.Fig. 8 X=0 Static temperature Fig. 9 X=0 Total temperatureTemperature distribution can be respectively obtained in the section Z=0.5, Z=0.75, Z=1, Z=1.25, Z=1.5, Z=1.75 and Z=2 in the cyclone shown in Fig. 10, which also shows that temperature near the wall is relatively high, the reason for which is that friction between the flow and wall and compression effect of centrifugal force can lead the enhancement of temperature. Temperature gradient of each cross-section shows circular ring, better symmetry and a certain degree irregularity that can be caused by the different local turbulence.Fig. 10 The temperature distribution on Z = 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2 cross sectionConclusionThis thesis puts forward the temperature distribution of the cyclone with type of CLT/A, and figures out that the overall temperature is about 373°C. Temperature difference in different region is less than one centigrade degree with the maximum temperature in the cone part and the minimum temperature in inlet tube and cylinder part of the cyclone, what’s more, the temperature is relatively higher near the wall. The air compression can lead the higher temperature in the lower part, so the cone part has the maximum temperature which is caused by the strengthen impact of air compression. The higher temperature near the wall is caused by the friction between the wall and flow. The total temperature in the cyclone stays a constant value with almost no change and local difference can be obtained.References[1] F. Boysan, B. Ewan and J.
