t-p变换方法与应用，应用于地震资料处理中，是比较好的一本书(tp transform methods and applications used in seismic data processing is a good book)

多个雷达间坐标转换，极坐标和直角坐标转换(Coordinate conversion between different radars, polar coordinates and Cartesian coordinates)

单炮地震记录正演模拟，有详细说明，可供地球物理初学者学习(Single-shot seismogram modeling, there are detailed instructions, for beginners to learn geophysics)

利用IDL读取MODIS影像L1B和MOD03数据(HDF格式),计算遥感植被指数NDVI(MODIS images using IDL to read L1B and MOD03 data (HDF format), the calculation of remote sensing vegetation index NDVI)

用于电力系统分析的IEEE118节点的典型系统结构(Power System Analysis for the IEEE118 system structure of a typical node)

说明：  这是将波动方程分解为上行波下行波的源程序 把两个源代码放在一起，运行即可了！(This is the wave equation will be decomposed into up-going wave downlink wave source source code of the two together, you can run the!)

NET Core+EF Core实例,自己使用了,很好,没有问题(NET Core+ EF Core instance, oneself use, is very good, no problem)

Mifare USBMiCard.DLL - Visual C/C++ Source Program(Mifare USBMiCard.DLL- Visual C/C++ Source Program)

牛顿－拉夫逊法潮流计算 基本步骤： 　　（1）形成节点导纳矩阵 　　（2）将各节点电压设初值U， 　　（3）将节点初值代入相关求式，求出修正方程式的常数项向量 　　（4）将节点电压初值代入求式，求出雅可比矩阵元素 　　（5）求解修正方程，求修正向量 　　（6）求取节点电压的新值 　　（7）检查是否收敛，如不收敛，则以各节点电压的新值作为初值自第3步重新开始进行狭义次迭代，否则转入下一步 　　（8）计算支路功率分布，PV节点无功功率和平衡节点柱入功率。(Newton-Raphson method flow calculation basic steps : (1) formation of nodal admittance matrix (2) to set up the initial node voltage U, (3) the initial node-generation-related demand. calculated that the constant term formula Vector (4) nodes will be incorporated into the initial voltage-seeking, calculated Jacobian matrix elements (5) solving that equation, seek to amend the vector (6) to strike a new node voltage value (7) to check whether convergence, if not restrained. concentrated in the nodes of the new voltage as the initial value since the first three steps to re-start the narrow iterations. Otherwise, turn into the next (8) Calculation branch power distribution, PV nodes reactive power and balance-node into power.)
