中国大陆强震等震线，时间为1966-1975年(isoseismal line1966-1975)

说明：  计算列车平稳性,计算sperling指标参数，可以画出频率和时间的图像(caculate the sperling index of the train)

VIPer53设计的开关电源,SCH及PCB,效率56％,很想提高效率,但有点难度.希望大家讨论.-VIPer53 switching power supply design, SCH and PCB, the efficiency of 56 percent, wanted to improve efficiency, but it

使用蒙特卡洛采样，计算圆柱体、立方体和四棱锥三个物体相交部分的体积(Monte Carlo sampling is used to calculate the volume of the intersecting parts of a cylinder, a cube and a quadripyramid.)

键盘 转换 哈哈 很好用的 但是可能会有些小问题但是问题不大 可以用(Conversion ha ha very good keyboard but may be used for small problems but can not be a big problem)

这是一个为了显示而做的字模软件，可以对文字，图形取模。并可以手绘图形。可以对所有的Windows字体取模，图形文件必须是单色的bmp格式的图片。可以指定设计的宽高以及取模方式，即可以对单一的设计元素取模，也可以对整个设计区域取模。可以保存设计，也可以对设计进行编辑。-This is a show in order to make the matrix and the software, can be text, graphics modulus. And can be hand-drawn graphics. Of all the Windows fonts modulus, graphics files must be a monochrome bmp format images. Can specify the design, as well as the width of high modulus, that is, can a single design element modulus can also be the entire design region modulus. Can be preserved for the design, the design can also be edited.

采用自稳定域法分析二姐系统稳定性，并使用simulink仿真(Adopted sister from the stable region system stability analysis and simulation using simulink)
