风能利用系数计算

C#读取dxf中的圆坐标，并且把所有坐标绘图显示出来(C# Reads the Circular Coordinates in DXF)

说明：  这是一个简单的2d图形动画，是用VC编的，适合初学者参考。(This is a simple 2d graphics animation, VC series is the reference for beginners.)

可见光通信是通过驱动电路将电信号转换成光信号并通过LED 发射出去，接收端通过光检测设备接收光信号，并提取其中有用的信号分量，从而实现通信。 研究OFDM和MIMO的关键技术，并针对室内可见光通信系统提出合适的MIMO-OFDM 方案。(isible light communication is through the drive circuit converts electrical signals into light signals and transmitted through LED, the receiving end through the optical detection device receives the light signal, and extract the useful signal component, so as to achieve communication. The key technologies of OFDM and MIMO are studied, and an appropriate MIMO-OFDM scheme is proposed for indoor visible light communication systems.)

这是一个VHDL（硬件描述语言）的编译器，更确切说是一个解释器，输入是VHDL语言，输出是经过提到后的符号表，也就是将VHDL中的重要变量比如输入输出变量和DFF等保存下来。-This is a VHDL (hardware description language) compiler, more precise explanation is a device that is VHDL input, output was mentioned after the symbol table to VHDL is the important variables such as input and output variables and other DFF preserved.

胡广书的现代信号处理书籍和相关代码,写的不错，pdf也很清晰(mordem signal poerssos)

Labview的入门教材，word版的，内容挺不错。-Labview entry materials, word version of the content very good.

1、 基于LABVIEW的谐波分析仪的设计（声卡/PCI6024E/USB/串口） (1) 学习LABVIEW下的程序设计调试方法。 (2) 控制声卡采集数据实现频谱测量功能。 (1, based on the LABVIEW harmonic analyzer design (sound card/PCI6024E/USB/Serial) (1) learning under LABVIEW program design debugging method. (2) control of sound data collection realize spectrum measurement capabilities.)
