高斯投影坐标正反算

二阶标量声波差分有限差分正演模拟，加PML吸收边界（完全匹配层），实现边界无反射效果，可以添加各种模型，进行正演模拟。(2D -acoustic equation finite-difference forward modelling,which include perfect match layer.it can achieve the result that have no reflection,and it also can achieve other the result of model.)

可以方便的进行三次以内方幂求和公式的自动推导 此代码为独创(Can easily be a power of less than three times the automatic derivation of the summation formula for the original code)

NOMA仿真，能够实现两用户的NOMA系统仿真的实现，对于初入NOMA者非常有用(NOMA simulation, which can realize the simulation of two-user NOMA system, is very useful for new entrants to NOMA.)

用c++完成的双链表源代码-complete with the source code-List

说明：  逆变器的simulink仿真，采用dq解耦的空间矢量控制模式(Inverter simulink simulation, using dq space vector control mode decoupling)

本文从现场总线控制系统的发展现状出发，遵循现场总线控制系统标准的体系结构，仍由通用组态软件实现监控管理功能，由现场总线智能仪表实现生产控制功能。但在连接通用组态软件与现场总线智能仪表的信息通道中，采用OPC服务器、OPCActiveX控件取代10驱动程序，实现与Matlba数据共享和互联，无干扰地增加Matlba强大的符号、数值计算、矩阵运算以及图形显示的功能，实施先进控制、优化控制。 -This article from the fieldbus control system development of the current situation, following the standard fieldbus control system architecture, generic configuration software is still realize monitoring and management functions, by the field bus intelligent instruments of production control functions. However, in general configuration software to connect with fieldbus intelligent instrument information channel, the use of OPC server, OPCActiveX controls to replace the 10 drivers, and realize data sharing and Matlba the Internet without interference to increase Matlba powerful symbols, numerical calculation, matrix calculation and graphical display features, the implementation of advanced control, optimal control.

ad转换器ads822e/ads822的驱动模块(AD converter ads822e/ads822 driver module)

建立简单的层状模型，共三层，褶积合成地震记录，使得数据随机缺失30%，分别用傅里叶变换、短时傅里叶变换、s变换、小波变换对地震数据进行时频分析。(A simple layered model with three layers and convolution synthetic seismogram is established. The data are randomly missing by 30%. Time-frequency analysis of seismic data is carried out by Fourier transform, short-time Fourier transform, S transform and wavelet transform, respectively.)
