JabRef 中文帮助文档
说明：本文译自JabRef帮助文档，也可查看：/help/Contents.php。
------------------------------------------------------------------------------------------------------------------- JabRef中文手册：一、域关于bibtexJabRef能帮你处理bibtex数据库。
但须注意，在编辑文献题录时要确保你的数据库能被bibtex程序正确处理。
Bibtex域bibtex中有许多不同的域，JabRef也能设定一些附加的域。
通常，你可在包含文本的域内使用LaTex命令。
Bibtex会自动格式化你的文献列表，根据你的参考文献风格将列表中某些域转成大写或小写。
为保证特定的字符保持大写，请把它们用大括号包含起来，例如{B}elgium。
部分域类型的说明：z Bibtexkey：是用在LaTex文件中引用题录的独特字符串。
需要注意的是：从LaTex中引用题录时，此关键词必需和文献字符串的大小写完全匹配。
z address：地址，通常指出版者或其他机构。
对于一些大的出版社，van Leunen建议整个忽略。
而对于一些小的出版社，给出完整的地址对读者会有帮助。
z annote：即annotation，注释。
标准的参考文献格式不使用注释，但是一些程序用它来产生注释型的参考文献。
z author：作者。
该域应该包含一条文献题录中完整的作者列表。
作者名之间用and分隔，作者数目多于三个也是一样。
名字可以用两种等价的方式书写：–Donald E. Knuth （名+ middle name +姓）或者 Knuth, Donald E（姓+“,”+名）– Eddie van Halen 或van Halen, Eddie（译注：上面两行是两个例子，每一行中是两种书写方式。
）如果作者多于两个，必需使用后一种方式（带逗号的方式）以区别中间名（middle names）和姓（last names）。

1.文档介绍和说明本文档介绍了FE-fatigue软件产品基于有限元应力计算结果进行疲劳寿命估计。
有关nCode软件的基础理论信息，请查询nSoft在线疲劳分析理论手册。
像这样加粗的文本，表示输入表单的名称，文件名，或在选择列表上的选项等，这些来提醒您注意一些注意事项。
1.1.FE-fatigue功能FE-fatigue能实现在设计过程的早期阶段对零部件进行疲劳计算，从而使设计分析师对设计的耐久性方面性能进行评估。
只要进行结构应力计算，疲劳计算通常也是必要的。
当部件、材料和制造工艺的类型适当时，FE-fatigue提供更多有价值的设计信息，这些信息可以减少产品上市时间、节省资金，同时在设计过程中更快提供最优的设计方案。
FE-fatigue将有限元分析的应力或应变数据结果作为输入文件，然后将这些信息和循环变化负荷和材料数据相结合。
通过这个组合文件估计有限元模型每个节点或单元的疲劳损伤。
为了支持市场上许多FE软件，并提供一个一致的有限元疲劳分析界面，有限元数据从其原本的形式转换成一个通用的文件格式（.fes文件），其细节在theory.pdf文件中提供。
一个软件的能力取决于编译模块以正确格式提供数据给求解器的能力。
不同的疲劳计算方法需要不同的有限元分析结果，编译模块必须能够提供正确的数据以完成链接和分析。
疲劳分析的结果以适合寿命及损伤云图显示的形式返回给后处理器。
1.2.系统流程图基本的系统流程如图 1.1所示：输入文件类型如下：部分FES文件—由有限元软件产生；全部文件—NCODE软件所需要的分析文件；结果文件—适合之际导入前、后处理器的文件格式。
如果前后处理器不支持FES文件，可以使用以下的流程，如图 1.2所示：图 1.2不支持FES文件系统流程图2.快速开始实例实例在以下文件夹中给出：Windows和Unix系统*.ncx文件在$安装路径\nsdata*.ncl文件在$安装路径\demo每个FE-fatigue实例都有一个相对应的宏文件（见图 2.1），它能将实例所需要的所有文件拷贝到挡墙的工作目录下，宏运行可以通过prompt或是via菜单进入（如下）。

NUMECA帮助文档(六)
第十二章跨叶片截面模块12.1绪言本章针对透平机械讲述快速三维跨叶片截面模块的分析过程。
这个模块是全自动完成的并且利用一些NUMECA工具。
此外，附加模块FINE™/Design2D这些工具联系起来，可以进行叶片重新设计，改善叶片表面压力分布，关于这些详见第13章。
这个模块假设流动是轴对称的，并且流面形状和厚度也由用户提供或由参数自动生成(利用根部和顶部边界)。
几何输入数据必须由用户提供：1、流面及叶片这个流面上的截面或2、完整的叶片轮廓及端壁本模块由网格自动生成与NS湍流方程组成。
在下一节讲述这个跨叶片截面模块的界面及对用户的建议。
12-4节讲述自动生成网格的理论和求解方程。
12-5节讲述几何数据和输出结果。
12-6讲述实例。
12-2跨叶片截面模块的界面在FINE™/Design2D界面之下运行跨叶片截面模块，这些可以高速，简单，交互式求解。
所有参数可以在用户界面中选取，并自动创建输入文件及求解。
监视工具，MonitorTurbo,可以在计算中和计算后检查收敛情况及结果。
它可以实时查看叶片表面压力分布的收敛过程及叶片几何形状。
结果分析利用NUMECA CFViwe™后处理工具进行，自动进入跨叶片截面模式。
几何数据以ASCII输入文件列出，但是求解参数定义及边界条件在这个界面中列出。
这个截面的描述由FINE™/Design2D界面中的菜单创建。
更详细的说明见12-5.12.2.1开始新的或打开现存S1面计算在开始界面下，Project Selection窗口允许创建新工程或打开现存工程。
对于创建新的跨叶片截面工程，按如下操作：1、单击按扭Create a New Project2、选取工程保存路径及输入文件名3、关闭Grid File Selection窗口，Design 2D不需要输入网格文件4、进入S1流面模块，菜单Modules/Design 2D如果要打开现存工程，在Project Selection窗口中单击Open an Existing Project 按扭，并在File chooser窗口中选取一个文件。
北京亚控 S7200 系列 组态王通讯帮助系列文档 说明书
组态王软件与西门子S7200 PLC通讯配置方案汇总此文档由北京亚控公司提供，仅作为组态王与OMRON PLC 通讯配置的使用参考，北京亚控公司不对此文档涉及的OMROM软硬件配置部分承担任何使用责任，OMRON软硬件的详细说明请参考OMRON厂家提供的使用说明，关于OMRON软硬件配置过程中的疑问请致电OMRON 厂家技术支持工程师。
目录串口通讯方式： (3)MPI通讯卡方式： (4)以太网通讯方式： (4)Profibus –DP通讯方式： (5)Profibus –S7通讯方式： (5)Modem通讯方式： (6)组态王软件和S7200 PLC 可以通过一下通讯链路进行通讯，具体说明如下：串口通讯方式：硬件连接：此种方式使用S7200系列PLC上的PPI编程口，使用西门子标准编程电缆或标准485电缆链接到计算机串口上:当使用计算机的RS232通讯口时：建议使用西门子专用紫色电缆和网络接头＋常规有源RS485/232转换模块（如研华的ADAM4520）进行PLC 485编程口和计算机标准232口的连接）；当使用计算机扩展RS485口时：建议使用西门子专用紫色电缆和网络接头直接进行PLC RS485编程口和计算机RS485口的连接。
注意：PLC的PPI口中9针口：3―DATA＋ ；8―DATA －适用场合：一般适用于一个PLC和一台PC进行直接串口通讯的场合，PLC和PC机之间距离较近；组态王对应驱动（常用直接驱动有3个）：（1）PLCÆ西门子ÆS7-200系列ÆPPI（2）PLCÆ西门子ÆS7-200系列Æ自由口（3）PLCÆ西门子ÆS7-200系列ÆModbus特殊软件需求：组态王所在的计算机不需要安装s7200编程软件。
各自具体配置按照组态王对应驱动帮助执行即可。
注意：因为PPI协议的特殊性，读取一个数据包一般需要400MS的时间，当用户反馈PPI 通讯速度慢时，请以此标准分析用户工程通讯速度慢是否在合理的范围；如果在该驱动所支持的合理范围内，用户仍然不满意时，建议更换为自由口或modbus通讯方式。

3D 坐标系
投影坐标系也逐渐地开始使用 z 值来测量平均海平面以上或以下的高程。 在下图中，标记 (2,3,4) 所记录的点在 x 轴方向距原点两个单位，在 y 轴方向距原点三个单位 并且高程为地球表面以上四个单位（例如平均海平面以上 4 米）。
地图投影中的属性和变形
由于地球是球体，所以制图人员和 GIS 专家所要面临的一个挑战就是如何使用平面坐标系表达真 实世界。要体会这种两难的困境，只需想一想如何将半个篮球变平即可；如果不改变它的形状或创 建不连续的区域，就无法做到这一点。将地球变平的过程称为投影，由此而产生了术语地图投影。
使用直角坐标系的地图投影
投影坐标系是指用于平面（例如打印的地图或计算机屏幕）的任何坐标系。 2D 和 3D 直角坐标系都可使用 x 值和 y 值（在后面会讲到，也可使用栅格的列和行）描述要 素的地理位置和形状。 直角坐标系使用两个轴：一条水平轴 (x)，表示东西方向，一条垂直轴 (y)，表示南北方向。两轴 的交汇点称为原点。地理对象的位置使用 (x,y) 标记法相对于原点进行定义，其中 x 表示沿水平 轴的距离，y 表示沿垂直轴的距离。原点定义为 (0,0)。 在下图中，标记 (4,3) 所记录的点在 x 轴方向距原点四个单位，在 y 轴方向距原点三个单位。
地理信息系统 (GIS) 是以可视化和分析地理引用信息为目的， 用于描述和表征地球及其他地理现象的 一种系统。 许多人已经将 GIS 视为最强大的信息技术之一，因为它致力于整合来自多种来源的知识（例如，作 为地图中的各种图层）并创建一个跨领域的合作环境。此外，对于大多数接触过 GIS 的人们来说，
它直观易懂，具有很大的吸引力。它将强大的可视化环境（使用地图进行沟通和可视化）与基于地理 科学的稳健的分析和建模框架相结合。 这种结合孕育出一项科学、可信且易于交流（通过地图和其他地理视图）的新技术。 在您开始使用 ArcGIS 时，应了解 GIS 的一些基础知识以及在软件的使用过程中 ArcGIS 如何实 现这些理论，这一点十分重要。在本部分中，您将会了解到有关一些 GIS 重要方面以及如何依据一 系列重要地图概念构建地理信息模型的信息。

本文将介绍APDL的基本使用方法，帮助使用者更好地理解和应用这一强大的工具。
一、基本语法在APDL中，命令的基本格式为：```命令[选项1] [选项2] ... [选项n]```命令是要执行的操作，选项是可选的参数。
要定义一个直线单元，可以使用以下命令：```ET,1,2```这里，ET是定义元素类型的命令，1是元素类型的编号，2是元素类型的位置。
二、常用命令1. 定义材料参数在APDL中，可以使用MP命令来定义材料参数。
要定义一个弹性材料，可以使用以下命令：```MP,DENS,1,2700MP,EX,1,70e9MP,NUXY,1,0.3```这里，DENS是密度，EX是弹性模量，NUXY是泊松比，1是材料编号，2700是密度值，70e9是弹性模量值，0.3是泊松比值。
2. 定义几何结构```BLOCK,0,1,0,1,0,1```这里，0和1是立方体的起始点和终点的坐标。
3. 定义边界条件这里，1是节点编号，UX、UY、UZ是节点的位移自由度，0是边界条件的值。
三、常见问题解决在使用APDL时，可能会遇到一些常见问题，如：1. 语法错误：在输入命令时应注意命令的格式和参数的正确性。
2. 节点编号错误：在定义边界条件和加载条件时应确保节点编号的准确性。
3. 材料参数错误：在定义材料参数时应注意单位的统一和材料数据的准确性。
解决这些问题的关键在于不断练习，熟悉APDL的各种命令和语法，增加编程的经验和技巧。
四、使用技巧在使用APDL时，可以结合ANSYS的图形界面进行模型建立和后处理，更直观地查看模拟结果。
可以编写批处理脚本，自动化执行模拟过程，提高工作效率。

上面同样展示了主外键的操作。
你也可以添加其他操作：检验，触发器，约束性，索引。
一个数据模型表在EA中表现为一个类表，创建方法和其他类型的表一样。
创建一个表格什么是表关系模型数据库中，最基础的模型结构就是“表”。
一个表代表了具有相同结构的一系列记录。
UML数据模型配置文件中的表表现为一个衍型类，这就是说，一个带着衍型的类元素作用于它之上。
一个表的图标表示在图表的右上方。
创建一个表通过以下步骤创建一个表：1、选择一个表；2、选择工具条选项中的更多工具|扩展|数据模型菜单；3、点击元素列中的表格元素，然后点击表。
一个表格就展示在表上了；4、如果类：表n属性对话框没有显示，双击表来显示它；5、在名称一栏，键入一个合适的名称，根据需要键入其他的属性。
6、点击OK按钮。
设置表格属性一旦你创建了一个表，你可以设置它的属性。
下面描述的大部分表的属性都可以在属性对话框里设置，一小部分通过键入标签值来实现，比如说，设置表所属人的值，或者，为了和MySQL兼容，需要设置表选项。

Stata帮助文档说明书
4Getting helpSystem helpStata’s help system provides a wealth of information to help you learn and use Stata.Tofind out which Stata command will perform the statistical or data management task you would like to do,you should generally follow these steps:1.Select Help>Search...,choose Search all,and enter the topic or keywords.This search willopen a new Viewer window containing information about Stata commands,references to articles in the Stata Journal,links to Frequently Asked Questions(FAQ s)on Stata’s website,links to videos on Stata’s YouTube channel,links to selected external websites,and links to user-written commands.2.Read through the results.If youfind a useful command,click on the link to the appropriatecommand name to open its helpfile.3.Read the helpfile for the command you chose.4.If you want more in-depth help,click on the link from the name of the command to the PDFdocumentation,read it,then come back to Stata.5.If thefirst helpfile you went to is not what you wanted,either click on the Also See buttonand choose a link to related helpfiles or click on the Back button to go back to the previous document and go from there to other helpfiles.6.With the helpfile open,click on the Command window and enter the command,or click onthe Dialog button and choose a link to open a dialog for the command.7.If,at any time,you want to begin again with a new search,enter the new search terms in thesearch box of the Viewer window.8.If you select Search documentation and FAQs,Stata searches its keyword database for officialStata commands,Stata Journal and STB articles and software,FAQ s,and videos.If you select Search net resources,Stata searches for user-written commands,whether they are from the Stata Journal,the STB,or elsewhere;see[GSW]19Updating and extending Stata—Internet functionality for more information.Let’s illustrate the help system with an example.You will get the most benefit from the example if you work along at your computer.Suppose that we have been given a dataset about antique cars and that we need to know what it contains.Though we still have a vague notion of having seen something like this while working through the example session in[GSW]1Introducing Stata—sample session,we do not remember the proper command.Start by typing sysuse auto,clear in the Command window to bring the dataset into memory.(See[GSW]5Opening and saving Stata datasets for information on the clear option.) Following the above approach,1.select Help>Search....2.check that the Search all radio button is selected.3.type dataset contents into the search box and click on OK or press Enter.Before we pressEnter,the window should look like12[GSW]4Getting help4.Stata will now search for“dataset contents”among the Stata commands,the reference manuals,the Stata Journal,the FAQ s on Stata’s website,and user-written commands.Here is the result:5.upon seeing the results of the search,we see two commands that look promising:codebookand describe.Because we are interested in the contents of the dataset,we decide to check out the codebook command.The[D]means that we could look up the codebook command in the Data Management Reference Manual.The blue codebook link in(help codebook)means that there is a system helpfile for the codebook command.This is what we are interested in right now.[GSW]4Getting help3 6.click on the blue codebook link.Links can take you to a variety of resources,such as helpfor Stata commands,dialogs,and even webpages.Here the link goes to the helpfile for the codebook command.7.what is displayed is typical for help for a Stata command.Helpfiles for Stata commandscontain,from top to bottom,these features:a.The quick access toolbar with three buttons:i.The Dialog button shows links to any dialogs associated with the command.ii.The Also See button shows links to related PDF documentation and helpfiles.iii.The Jump To button shows links to other sections within the current helpfile.b.The veryfirst link in the Title section is a link to the manual entry for the command inthe PDF documentation.Clicking on the link will open your PDF viewer and show you the complete documentation for the command—in this case,codebook.c.The command’s syntax,that is,rules for constructing a command that Stata will correctlyinterpret.The square brackets here indicate that all the arguments to codebook are optional but that if we wanted to specify them,we could use a varlist,an if qualifier,or an in qualifier,along with some options.(Options vary greatly from command to command.) The options are listed directly under the command and are explained in some detail later in the helpfile.You will learn more about command syntax in[GSW]10Listing data and basic command syntax.d.A description of the command.Because“codebook”is the name for big binders containinghard copy describing each of the elements of a dataset,the description for the codebook command is justifiably terse.e.The options that can be used with this command.These are explained in much greaterdetail than in the listing of the possible options after the syntax.Here,for example,we can see that the mv option can look to see if there is a pattern in the missing values—something important for data cleaning and imputation.4[GSW]4Getting helpf.Examples of command usage.The codebook examples are real examples that step throughusing the command on a dataset either shipped with Stata or loadable within Stata fromthe Internet.g.The information the command stores in the returned results.These results are usedprimarily by programmers.For now,either click on Jump To and choose Examples from the drop-down menu or scroll down to the examples.It is worth going through the examples as given in the helpfile.Here is a screenshot of the top of the examples:Searching helpSearch is designed to help youfind information about statistics,graphics,data management,and programming features in Stata,either as part of the official release or as user-written commands.When entering topics for the search,use appropriate terms from statistics,etc.For example,you could enter Mann-Whitney.Multiple topic words are allowed,for example,regression residuals.When you are using Search,use proper English and proper statistical terminology.If you already know the name of the Stata command and want to go directly to its helpfile,select Help>Stata Command...and type the command name.You can also type the command name in the Searchfield at the top of the Viewer and press Enter.Help distinguishes between topics and Stata commands because some names of Stata commands are also general topic names.For example,logistic is a Stata command.If you choose Stata Command...and type logistic,you will go right to the helpfile for the command.But if you choose Search...and type logistic,you will get search results listing the many Stata commands that relate to logistic regression.[GSW]4Getting help5 Remember that you can search for help from within a Viewer window by typing a command in the command box of the Viewer or by clicking the magnifying glass button to the left of the search box,selecting the scope of your search,typing the search criteria in the search box,and pressing Enter.Help and search commandsAs you might expect,the help system is accessible from the Command window.This feature is especially convenient when you need help on a particular Stata command.Here is a short listing of the various commands you can use:•Typing help commandname is equivalent to selecting Help>Stata Command...and typing commandname.The helpfile for the command appears in a new Viewer window.•Typing search topic in the Command window produces the same output as selecting Help> Search...,choosing Search all,and typing topic.The output appears in a new Viewer window.•Typing search topic,local in the Command window produces the same output as selecting Help>Search...,choosing Search documentation and FAQs,and typing topic.The output appears in the Results window instead of a Viewer.•Typing search topic,net in the Command window produces the same output as selecting Help>Search...,choosing Search net resources,and typing topic.The output appears in the Results window instead of a Viewer.See[U]4Stata’s help and search facilities and[U]4.8search:All the details in the User’s Guide for more information about these command-language versions of the help system.The search command,in particular,has a few capabilities(such as author searches)that we have not demonstrated here.The Stata reference manuals and User’s GuideAll the Stata reference manuals come as PDFfiles and are included with the software.The manuals themselves have many cross-references in the form of clickable links,so you can easily read the documentation in a nonlinear way.Many of the links in the helpfiles point to the PDF manuals that came with Stata.It is worth clicking on these links to read the extensive information found in the manuals.The Stata help system, though extensive,contains only a fraction of the information found in the manuals.The Stata reference manuals are each arranged like an encyclopedia,alphabetically,and each has its own index.The User’s Guide also has an index.The Glossary and Index contains a combined index for the User’s Guide and all the reference manuals.This combined index is a good place to start when you are looking for information about a command.Entries have names like collapse,egen,and summarize,which are generally themselves Stata commands.Notations such as[R]ci,[R]regress,and[R]ttest in the Search results and helpfiles are references to the Base Reference Manual.You may also see things like[P]#delimit,which is a reference to the Programming Reference Manual,and[U]9The Break key,which is a reference to the User’s Guide.For a complete list of manuals and their shorthand notations,see Cross-referencing the documentation, which immediately follows the table of contents in this manual.For advice on how to use the reference manuals,see[GSW]18Learning more about Stata,or see[U]1.2The User’s Guide and the Reference manuals.6[GSW]4Getting helpThe Stata Journal and the Stata Technical BulletinWhen searching in Stata,you will often see links to the Stata Journal.The Stata Journal is a printed and electronic journal,published quarterly,containing articles about statistics,data analysis,teaching methods,and effective use of Stata’s language.The Journal publishes peer-reviewed papers together with shorter notes and comments,regular columns,tips,book reviews, and other material of interest to researchers applying statistics in a variety of disciplines.The Journal is a publication for all Stata users,both novice and experienced,with different levels of expertise in statistics,research design,data management,graphics,reporting of results,and Stata,in particular.See for more information.There you may browse the archive,subscribe, order PDF copies of individual articles,and view at no charge copies of articles older than three years.The predecessor to the Stata Journal was the STB.Even though the STB is no longer published,past is-sues contain articles and programs that may interest you.See /bookstore/stbj.html for the table of contents of past issues,and see the STB FAQ s at/support/faqs/res/stb.html for detailed information on the STB.Associated with each issue of both the Stata Journal and the STB are the programs and datasets described therein.These programs and datasets are made available for download and installation over the Internet,not only to subscribers but to all Stata users.See[R]net and[R]sj for more information.Because the Stata Journal and the STB have had several articles about meta-analysis,if you select Help>Search...,choose Search documentation and FAQs,type meta analysis,and scroll down a bit,you will see some of these references:SJ-12-4refers to volume12,number4of the Stata Journal.This is an example of a Stata Journal article that describes a new user-written command.The command can be downloaded and installed to extend the abilities of Stata.See Downloading user-written programs in[GSW]19Updating and extending Stata—Internet functionality for more information.[GSW]4Getting help7 SJ-11-2refers to volume11,number2of the Stata Journal.This is an example of a Stata Journal article that updates the mvmeta user-written command.Clicking on an SJ link,such as SJ12(4):605--622,will open a browser and take you to the Stata Journal website,where you can download abstracts and articles.The Stata Journal website allows all articles older than three years to be downloaded for free.Links to other sites where you can freely download programs and datasets for Stata can be found on the Stata website;see /links/.See Downloading user-written programs in [GSW]19Updating and extending Stata—Internet functionality for more details on how to install this software.Also see[R]ssc for information on a convenient interface to resources available from the Statistical Software Components(SSC)archive.We recommend that all users subscribe to the Stata Journal.See[U]3.5The Stata Journal for more information.Stata videosStata has a YouTube channel where you can watch short videos explaining specific topics in Stata, such as running t tests orfitting regression models.The easiest way to see a list of available videos is to type help videos in the Command window.。
