优化设计软件 isight -8.0 的license ,很有参考价值,,多平台 -Optimization design software isight-8.0

计算机辅助正弦交流电路分析的理论及实现过程。分析方法采用节点分析法。采用了把一个二端元件定义一支路的概念，这种处理方法在网络分析中具有简单、易于掌握的特点。而在解线性方程时采用大家所熟悉的高斯―约当消去法。在建立方程的过程中采用的是形成Gn，Jn的直接填写法。为使读者理解编写通用程序的思路和方法，使用了大量的流程图。程序能处理含有导纳支路、电流源支路、电压源支路、四种受控源支路及含有互感支路的正弦稳态电路。-sinusoidal AC circuit computer-aided analysis of the theory and implementation process. Analysis using nodal analysis method. Used to bring a two-path components of a definition of the concept of this approach in network analysis is simple, easy-to-understand characteristics. The solution of linear equations used are all familiar with the Gauss-Jordan elimination method. The establishment of the equation used in the process of forming Gn, Jn fill in the direct method. In order to enable readers to understand the procedures for the preparation of general ideas and methods, the use of a large number of flow chart. Procedures can handle containing admittance slip current source slip voltage source slip four controlled source service road and the slip road with mutual inductance sinusoid
