这是在MATLAB环境下进行电力系统暂态稳定分析的pst源程序，该文件定义了一个3机9节点的系统模型。(This is the MATLAB environment in power system transient stability analysis of the pst source, the document defines a 3-machine 9-bus system model.)

运用New-Rapshon方法计算线接触常温弹流润滑程序，并绘制出压力和膜厚曲线图(Calculated using New-Rapshon EHL line contact process at room temperature, and draw out the pressure and film thickness curve)

可以实现电力系统负荷削减的判断,找出需要削减负荷的负荷点和母线编号(failed to translate)

水库调度应用,水库水文信息快速准确统计，实现制表自动化(Application of reservoir operation, Hydrological information fast and accurate statistics, the realization of automated tabulation)

地震解释处理matlab工具箱，由权威的CREWES小组发行，直接解压后复制到matlab的toolbox下就可使用(seismic interpretation Matlab toolbox, the authority issued CREWES group, unpacked directly copied to the Matlab toolbox can be used under)

道格拉斯-普克算法 (Douglas– Peucker algorithm，亦称为拉默-道格拉斯-普克算法、迭代适应点算法、分裂与合并算法)是将曲线近似表示为一系列点，并减少点的数量的一种算法。它的优点是具有平移和旋转不变性，给定曲线与阈值后，抽样结果一定。(The Douglas - puke algorithm (Douglas - Peucker algorithm, also called the lamer - Douglas - puke algorithm, iterative adaptive point algorithm, split and merge algorithm) is an algorithm that approximatively represents a curve as a series of points and reduces the number of points. It has the advantages of translation and rotation invariance. After a given curve and threshold, the sampling result is certain.)

通过引入流函数，可以直接画出不同雷诺数的方腔流流线图和涡量图(By introducing the flow function, the streamlines and vorticity diagrams of the square cavity flow with different Reynolds numbers can be directly drawn)
