该程序实现红绿灯的触摸屏控制，编程巧妙。(traffic lights with touch screen)

说明：  Z是模型一单位雨衰值,也是不考虑衰减因子的单位雨衰值 F是First,即第一模型的情况 F16 F165 F17分别是16GHz 16.5GHz 17GHz的情况,是模型一大气层下总雨衰值 F18km是模型一下18km实例的雨衰值 S是Second,即第二模型的情况 S16 S165 S17分别是16GHz 16.5GHz 17GHz的情况,是模型二大气层下总雨衰值 S16m S165m S17m分别是16GHz 16.5GHz 17GHz在模型二下每公里雨衰值 S1618km S16518km S1718km分别是16GHz 16.5GHz 17GHz在模型二下18km实例的雨衰值 T是Third,即第三模型的情况 T16 T165 T17分别是16GHz 16.5GHz 17GHz的情况,是模型三大气层下总雨衰值 T16m T165m T17m分别是16GHz 16.5GHz 17GHz在模型三下每公里雨衰值 T1618km T16518km T1718km分别是16GHz 16.5GHz 17GHz在模型三下18km实例的雨衰值 zhaosheng是只考虑天线噪声温度对雷达最大探测距离的影响 yushuai是综合考虑天线噪声温度和雨衰减对雷达最大探测距离的影响 其中,参数情况在各个程序中都有说明(err)

说明：  本程序基于matlab，采用牛顿拉夫逊法，对33节点潮流进行计算。(Calculating Power Flow of 33-Node Power Grid by Newton-Raphson Method)

图书管理系统用C++编写的图书管理系统，没有使用数据库，用文件读写方式保存(Library management system written using C++ library management system, not using the database stored with the file reading and writing)

电力系统潮流计算程序，对于电力系统分析有一定借鉴意义(Power flow calculation program for power system analysis have a certain reference)

测绘领域，该程序为一个边角网平差的程序，能够进行近似计算、间接平差计算，同时能够绘制出测量的网图，进行精度测评。(The field of surveying and mapping, the program for a corner net adjustment procedures can be approximately calculated, indirect adjustment calculation, at the same time able to draw a network diagram, measurement accuracy evaluation.)

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.)
