层合板的刚度的计算和验算，包括拉伸刚度A、弯曲刚度D以及耦合刚度B。 首先要给定层合板的各个参数，具体有：层合板的层数N；各单层的弹性常数E1、E2、 、G12；各单层对应的厚度；各单层对应的主方向夹角 。(The stiffness of laminated plates is calculated and checked, including tensile stiffness, A, flexural stiffness, D and coupling stiffness B. First of all, it is necessary to give the parameters of laminated plates, such as the number of plies N, the elastic constants of each layer, E1, E2, and G12, the thickness of each monolayer, and the angle of the main direction corresponding to each single layer.)

This is counter with T_FF.

广东工业大学硕士论文《SVPWM算法优化及其FPGA/CPLD实现》，在详细分析经典SVPWM算法基础上，提出一种优化算法，并在FPGA上实现。论文附录包含VHDL源码。(Guangdong University Thesis " SVPWM algorithm to optimize its FPGA/CPLD realization" in the detailed analysis of the classical SVPWM algorithm is proposed based on an optimization algorithm, and implemented on FPGA. Paper appendix contains VHDL source code.)

改VHDL代码可以实现超声波测距的功能，其精确度达到US级，可以用七段数码管显示其数值(sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging )

电梯控制，包括楼层按键相应，显示上下状态。(Elevator control, including the floors of the corresponding button to show the whole state.)

小波提升算法源码，里面一个txt文件可以当作算法参考；(Wavelet lifting algorithm source code, inside a TXT file can be used as algorithm reference;)

实用的程序代码，希望对大家有用，已经调试通过-Practical program code, in the hope that useful to everybody, has debugging through
