IEEE 标准测试系统原始数据以表格形式给出了 IEEE—14，30，57，118 节点标准测试系统的原始数据和潮流结果，以及供参考用的发电机经济参数、发电机出力限值。其中，IEEE—30 节点系统还给出了电费用最小优化潮流的计算结果。(IEEE standard test systems raw data in tabular form gives the IEEE-14, the original data and trend results 30,57,118 node standard test systems, as well as for economic parameters reference generator, the generator output limits.)

三相电压源型逆变器的滞环跟踪PWM的simulin模型，我使用的是matlab2012a(current lagloop tracking PWM inverter)

总体X服从非中心卡方分布，求两个参数的极大似然估计 输入：样本数据 输出：参数估计值n，v 内有详细说明(Overall X obey non-central chi-square distribution, find the two parameters MLE)

多边形网格相交区域搜索,MATLAB源程序，含有若干示例(Polygon mesh intersection area search, MATLAB source, contains a number of examples)

In this file, the case of polymer casting is considered as an unsteady state heat transfer problem. The explicit scheme of finite difference approach is considered to solve the governing partial differential equation in one dimensional (radial) cylindrical coordinates.

设置电容型脉冲电源的电容、电感、回路和负载的电感电阻等参数，可以计算出脉冲电源的输出电流。(The output current of the pulse power supply can be calculated by setting parameters such as capacitance, inductance, loop and load inductance resistance of the pulse power supply.)

说明：  信号源仿真，信号成型，4QMA调制，QPSK，阵列信号接收(source simulation，Signal shaping ，4QAM,QPSK，array signal receive)

说明：  离散数据的快速傅里叶变换。读取一段数值模拟得到的时间历程曲线，进行fft变换，得到幅频曲线。(Fast Fourier transform of the discrete data. Read the section of numerical simulation of the time course of the curve, fft transform, the amplitude-frequency curve.)
