一是利用计算机对正整数进行素因子分解认识素数，通过运用筛法与试除法寻找一定范围内的素数，体会到筛法比试除法有效但无法找出所有素数；二是通过若干特殊形式的素数的研究，寻找素数生成公式，发现一些结论；三是借助于非线性拟合技术，观察素数分布规律，利用其研究有关数论问题。(The first computer was used to prime factor decomposition of positive integers understanding of prime numbers, through the use of screening method and trial division to find prime numbers within a certain range, the division experienced a test of an effective screening method but can not identify all the prime numbers second is through a number of special form of prime numbers research, looking for prime number generation formula, found that some of the conclusions third, by means of non-linear fitting technique to observe the distribution of prime numbers, using their research on number theory problems.)

说明：  用有效独立法实现传感器优化布置，效果一般，但可供借鉴(Using the effective independence method to realize the optimal arrangement of sensors)

matlab做的buck闭环仿真，自己做的，这个是闭环的，加反馈，PID补偿费，用的是增量式PID，连续，稳定(simulation of buck with feenback PID)

在MATLAB中求图像纹理特征，小波包分析提取振动信号中的特征频率，包括脚本文件和函数文件形式。( In the MATLAB image texture feature, Wavelet packet analysis to extract vibration signal characteristic frequency, Including script files and function files in the form.)

说明：  这是一个AWGN信道下，编译码仿真的C程序。本人已经用它产生数据绘制折线图！包含编码，译码，信道模拟，误码率计算 …… ,程序结构清晰，不复杂，适合与初学者来了解，基本通信流程！(This is an AWGN channel, the decoding simulation C program. I' ve used it to generate data to draw a line chart! Including encoding, decoding, channel simulation, bit error rate ... ..., the program structure clear, not complicated, for with the beginners to understand, the basic communication process!)

说明：  在X，y方向分别放水平磁环，在Z轴上放电偶极子，给出信号方位角估计随极化角度和俯仰角的变化的估计性能(In X, y directions are the level of magnetic release, discharge in the Z-axis dipole is given with the polarization angle estimate signal azimuth and elevation changes in the estimation performance)
