单相功率因数校正PFC的原理和方法，通过对Boost型滞环控制的DC-DC变换器采用Matlab进行仿真，获得了最后校正的功率因数结果，说明这种PFC方案的能获得良好的效果，适用于多种场合。(The principle and method of single-phase PFC are introduced. By simulating the Boost hysteresis-controlled DC-DC converter with MATLAB, the final corrected PFC results are obtained. It shows that this PFC scheme can achieve good results and is suitable for many occasions.)

波浪模拟UDF程序，可以模拟二位数值水槽产生波浪，便于应用fluent求解波浪模拟问题-UDF wave simulation procedures

生化反应动力学参数估计，用多变量线性回归方法估计动力学参数(Biochemical kinetic parameters estimated by multiple linear regression methods are used to estimate kinetic parameters)

说明：  双向DAC仿真，可以稍作修改进行调整，即可使用。(Two-way DAC simulation, can be slightly modified to adjust, you can use.)

一个测试反应能力的HTML5网页游戏：一个都不能死附代码，非常有挑战性的小游戏。玩家要同时控制多个火柴人在不同的线条上奔跑，并且还得躲避重重障碍，不能死掉任何一个火柴人，尽可能的跑得更远，最多可控制五个火柴人跑酷，看下你的反应能力，想挑战的就快来吧。
