300Hz带阻滤波，用matlab中fdatool设计参数，然后用labview开发(300Hz bandstop filter, IIR. Firstly, the coefficients are calculated by Fdatool design tool in matlab, and then developed by labview.)

完美世界游戏客户端pck解包打包工具，同时支持cup更新包解包。(Perfect world game client PCK unpack packaging tools, at the same time support CPU update package. )

说明：  基于matlab中的双馈式风力发电机组的建模与仿真，可实现机侧和网测的仿真(Modeling and Simulation of doubly-fed wind turbine based on Matlab can realize the simulation of generator side and network measurement)

使用LabVIEW开发平台编制的程序称为虚拟仪器程序，简称为VI。LabVIEW（Laboratory Virtual instrument Engineering Workbench）是一种图形化的编程语言，它广泛地被工业界、学术界和研究实验室所接受，视为一个标准的数据采集和仪器控制软件。LabVIEW集成了与满足GPIB、VXI、RS-232和RS-485协议的硬件及数据采集卡通讯的全部功能。它还内置了便于应用TCP/IP、ActiveX等软件标准的库函数。这是一个功能强大且灵活的软件。(Using the LabVIEW development platform known as the virtual instrument programmed process, referred to as VI. LabVIEW (Laboratory Virtual instrument Engineering Workbench) is a graphical programming language, it is widely used by industry, academia and research laboratories accepted as a standard data acquisition and instrument control software. LabVIEW integration and satisfaction with GPIB, VXI, RS-232 and RS-485 protocol communications hardware and data acquisition card full functionality. It also has built easy to use TCP/IP, ActiveX software such as standard library functions. This is a powerful and flexible software.)

This tutorial introduce VHDL code for clock pulse and 4-bit counter. With four bits, the counter count from 0 to 15. The timing of the counter is controlled by a clock signal. There will be a clear signal which can reset the counter value.

说明：  ay emulator4 code in c language

说明：  该程序可用于对abaqus结果数据进行处理，对每个材料点应力进行计算，并获取临界面的应力应变参数。(The program can be used to process the ABAQUS odb data, calculate the stress of each material point, and obtain the stress and strain parameters of the critical plane.)
