对三维融合后的图像进行质量评价，其中包括信息熵、平均梯度、标准差、空间频率、均方根误差、峰值信噪比 (The three-dimensional fusion of the image quality uation, including information entropy, the average gradient, standard deviation, spatial frequency, root mean square error, peak signal to noise ratio)

MATLAB下绘制三维极坐标图，输入极径和角度范围，还可以选择画图的种类，也可以画等高线图(Draw three-dimensional polar plot using MATLAB.)

电流互感器，用于与pscad交互使用，各部分齐全，功能完善(Current transformers for interactive use with pscad, each part is complete, fully functional)

用于瑞雷波频散曲线的提取计算，对初学者还是很有用处的(used for rayleigh wave dispersion curve)

基于PSCAD 4.5搭建的IEEE 第一标准测试模型，可以用于次同步振荡的研究。(The first IEEE standard test models built based on PSCAD 4.5 can be used to study sub-synchronous oscillations.)

使用PSCAD建立了一个三相交流的基于TCR的SVC仿真模型，效果很好(Use PSCAD established based SVC TCR of a three-phase AC simulation model, the effect is very good)

对给定的离散点，先拟合成B样条曲线，再求B样条曲线曲率(The program can help you to get the curvature of the B-spline curve from discrete points.)

针对ANSYS开发的APDL，该命令流用于生成中国60kg钢轨，从而避免了繁琐的多曲线建模，十分方便。另外，基于该命令流，用户可以推演出更复杂的型面优化建模。(Developed for ANSYS APDL, the order flow is used to generate Chinese 60kg rails, thus avoiding the cumbersome multi-curve modeling, very convenient. In addition, based on the order flow, the user can deduce a more complex profile optimization modeling.)

基于PSCAD的风机建模与仿真简单示例，包括风源、风机、发电机参数的设定。(Modeling and Simulation of Wind Turbine based on PSCAD)

说明：  一个简单的绘图程序，直接拖放产生圆形，矩形，正四边形，等多边形(print program)
