matlab实现视频读取的文件，欢迎参考使用(matlab to read the files of video, please reference)

calculation of power injected to power flow

This program is to plot 3-D radiation pattern of 2-element array antenna.

Welch法功率谱估计的C语言程序 相关人员可以参考(Welch method of power spectrum estimation of the C language program)

vc与matlab7的混编，采用的混编方式是通过shared(vc matlab7 with the mixing of the way through the air shared)

基于ANSYS APDL二次开发的航电设备的动力学扫频分析，载荷输入条件为交越频率以下为恒定位移，交越频率以上为恒定加速度。我将加速度输入转换为位移输入，将位移和加速度两段输入载荷统一按照位移载荷输入，将位移存入表数组，利用ANSYS APDL自动将扫频范围内的位移载荷存入表数组，并循环加载计算，实现了该工程结构的正弦扫频振动分析。(Kinetic sweep analysis, load input conditions of secondary development based on ANSYS APDL avionics for the crossover frequency less constant displacement, above the crossover frequency is constant acceleration. I will convert the input displacement input acceleration, displacement and acceleration loads unity in accordance with the displacement of the two input load input, the displacement of the array into the table using ANSYS APDL automatically load displacement within the sweep range of the array into the table, and cyclic loading calculated to achieve a swept sine vibration of the project structure.)

其实操作系统在调用 main 函数时是传参数的，main 函数最标准的形式应该是 int main(int argc, char *argv[])，在第 6 节 “指向指针的指针与指针数组” 详细介绍。C 标准也允许 int main(void)这种写法，如果不使用系统传进来的两 个参数也可以写成这种形式。但除了这两种形式之外，定义 main 函数的其它写法都 是错误的或不可移植的。(The 88-bytes (704-bits) in the Configuration zone contain manufacturing identification data, general device, and system configuration, and access restriction control values for the slots within the Data zone. The values of these bytes can always be obtained using the Read command. The bytes of this zone are arranged as shown in Table 2-2)

DS证据，功能：融合x,y两行向量(经典Dempster-Shafer组合公式)(DS evidence features: integration of x, y two row vectors (classical Dempster-Shafer combination formula))

小波分析由于具有同时分析信号时域和频域的特性，所以使用小波分析技术对检测的信号进行变换，然后对具有故障特性的信号进行重构，最后通过希尔伯特变换进行解调和细化频谱分析，从而轴承中的故障信息成分就可以检测出来，以判断轴承发成故障的部位。(Wavelet analysis has the characteristics of both time and frequency domain, so the wavelet analysis technique is used to transform the signal, then the signal is reconstructed. Finally, the fault information components of the bearing can be detected by Hilbert transform.)
