Isaac Newton Philosophiae naturalis principia mathematica

最短路径和最小生成树-shortest path and minimum spanning tree

用PC调试GSM模块的软件，做为GSM开发工程师的有效利器-GSM module debugging using PC software, GSM as an effective tool for development engineers

通过MATLAB编程，实现对菲涅尔波带片的绘制，改变焦距F可以绘制不同焦距的波带片。(Drawing Fresnel zone plate by MATLAB)

说明：  隔离变压器和推挽变压器参数的设计，通过将变压器设计中所用到的公式用代码编辑到系统中，可以更快的根据所需指标来获取相应的参数，而且本系统中还集成了部分磁芯型号的相应参数和导线的参数，实现快速选取导线和磁芯，加快了变压器参数设计的周期，而且系统采用Visual Basic 6.0来设计界面，可以使设计人员更易操作。(The system is the design of the parameters of isolation transformer and push-pull transformer. By editing the formulas used in the design of transformer into the system with code, the corresponding parameters can be obtained more quickly according to the required indicators, and the system also integrates the corresponding parameters of some magnetic core models and the parameters of wires, so as to realize the rapid selection of wires and magnetic cores and speed up the change. The design cycle of press parameters and the interface design of the system using Visual Basic 6.0 can make the designer easier to operate.)
