通过本文及配套示例源码你可以更加灵活的控制Excel表格文件，其中包括创建新Excel文件、写入表格数据、读取表格数据(包括对原建Excel文件自已手工添加的行、列数据的准确读取)，删除已有Excel表格，对表格中指定行、列、单元格进行查询、插入、替换等操作，同时还可以将生成的Excel文件转换为按指定分隔符分隔的其它文本格式的文件-adoption of this sample source code and supporting you to be more flexible control of Excel documents, including the creation of new Excel file, write tabular data, reading the spreadsheet data (including the original Excel files built themselves manually add the rows and columns of data accurately read), has been deleted Excel spreadsheet, the forms were designated rows and columns, and cells to conduct inquiries, insert, replace, etc, and also can be generated for the Excel document conversion designated by separate segregated from the other website text files

Excel表格是输入输出经常需要涉及到的。操作Excel表格的方式也多种多样。比如，通过调用Excel程序的COM组件对Excel进行操作。但是，这种方式限制较多，且实现难度比较大。但是，用于访问数据库的组件ADO，是支持多种数据源的，其中就包括Excel文件。我们可以通过ADO组件对Excel文件进行读写访问。当然，在.NET平台上对应ADO数据访问组件的是ADO.NET组件。我编写的这个类就是通过ADO.NET实现了Excel文件的读写。由于时间仓促，功能还不是很完善，会在以后有时间的时候进行版本升级。也请各位高手多多批评指正。
-Excel spreadsheet input and output is often of the need to address. Operation Excel variety of ways. For example, by calling the Excel COM procedures for the operation of Excel. However, this approach is more limited and more difficult to achieve. However, for access to the database components ADO, is to support multiple data sources, including Excel file. We can ADO components to read and write Excel files visit. Of course,.NET platform counterparts ADO data access components of ADO.NET components. I prepared this category is achieved through ADO.NET read and write Excel files. Because time is so short, the function is still not perfect, will in future have the time for version upgrades.

感应电机的运行
INDUCTION MOTOR RUN
(Currents and speed as state variables)
The motor is running at a specified load. After reaching steady state in an initialization first run, the initial conditions are established for a second run in which the load is pulsating. The dynamic equations are expressed in canonical first-order matrix form adopting currents and speed as state variables, and are solved using ODE45.
The user has the choice of selecting one of three common (dq) reference frames: STATOR, ROTOR or SYNCHRONOUS.
The torque, speed,and current responses are plotted. -INDUCTION MOTOR RUN
