说明：  主要用来进行面波频散与反演分析。案例主要是用了冰岛的一个案例。(mainly to disperse the curve of surface wave and inversion.)

本人自编的另一个有限元软件，用来解决电磁声静电场问题。本是一个作业。经了不少心思。可以在程序内建模，加载荷，并求解，彩图显示结果。并输出模型文件，和结果文件。输出的结果文件可以再读入程序进行下一次的分析。(I directed another finite element software, used to solve electromagnetic acoustic electrostatic field problems. This is an operation. After a lot of efforts. The procedure modeling, load, and solving color pictures show results. Model and output documents, and the outcome document. The output of the document can be read into the process for the next analysis.)

分布式光伏发电利益相关方综合效益计算，针对分布式电源的运营，目前主要存在三种模式——自发自用、统购统销和合同能源管理。本软件通过对各利益方净收益和整体收益的定量计算，为相关政策的设计与调整提供依据。(Integrated benefit calculation software for distributed photovoltaic power generation stakeholders)

利用分形维数原理计算分段测井曲线的盒维数，从而定量化曲线分形特征。利用雷达图对分形数据进行分析。(The fractal dimension principle is used to calculate the box dimension of segmented logging curves, and the fractal characteristics of curves are quantified.)

说明：  圆筒型永磁直线电机铜simplorer的联合负载仿真(Joint Load Simulation of Cylindrical Permanent Magnet Linear Motor Copper Simorer)

西门子变频器t300说明书，分享给各位，希望能通过(The installation, connection and commissioning of the equipment and modules is not described here. These are provided in sufficient detail in the Instruction Manual of the equipment.)

算法交易，统计套利，配对交易python代码实现(Algorithm trading, statistical arbitrage, pair trading, Python implementation)

二维雷诺方程的matlab有限差分算法。(Matlab finite difference algorithm for two-dimensional Reynolds equation.)

用红外控制步进电机转动角度，并且用LCD显示，采用51单片机控制，转速误差在1%之内(With infrared control stepper motor rotation angle, and with LCD display, using 51 single-chip microcomputer control, speed error is within 1%)

将CATIA数据里面的2层和3层焊点，批量生成point点。(Two and three layers of solder joints in CATIA data are generated in batches.)
