基于一阶剪切变形板理论数值分析计算粘弹性功能梯度版蠕变(Based on first order shear deformation plate theory numerical analysis of functionally graded version of the calculation of viscoelastic creep)

平面磨床电永磁磁盘控制用电压调节程序，输入AC380V变DC220V电压输出。(Magnetic disk surface grinding machine with voltage regulation control program, enter AC380V change DC220V voltage output.)

自己写的matlab源码，用于球信号包络，非常好用，简单可靠。(Write their own Matlab source code for the ball signal envelope, very easy to use, simple and reliable.)

6阶多项式瓦格纳威利分布的源代码，实现良好的时频聚集性和精确的时频峰估计(6-order polynomial distribution of the source code of Willie Wagner, to achieve good time-frequency clustering and accurate estimates of time-frequency peak)

对原始信号进行四相相移键控调制，然后加入高斯白噪声，对加噪信号进行解调，对比解调信号与原始信号，计算误码率(The original signal quadrature phase shift keying modulation, and then adding Gaussian white noise, plus noise signal is demodulated, comparing the demodulated signal with the original signal, bit error rate calculation)

样本熵,用于进行信号的复杂度计算，已调试完成，可直接调用(sample entropy can be used to analyze the complexity of signal.)

二级倒立摆的建模及仿真，有兴趣的可以下下来参考，本人水平不是很高，所以做的不是很好！(Double inverted pendulum modeling and simulation, are interested can refer to the next down, I am not very high level, it is not good to do!)

problem related to statistics that are solved with the help of ANOVA

：本文主要研究了应用多相滤波技术的信道化接收机建模问题。在给定信道频谱划分方案下，推导了基于多相 滤波器的信道化接收机数学模型。并由此模型设计了一个四信道模拟系统。最后用仿真实验结果验证了模型的正确性。(research a wave filter )
