很好很强大!几何画板源码哦! 毕竟很多人都想要几何画板类型的东东做程序，这个就很好使！-Very good very strong! Geometer' s Sketchpad source Oh! After all, many people want the type of stuff to do GSP program, the very good to!

确定ge90发动机基本参数（巡航高度、巡航马赫数、空气流量、推力及级数）后，运行程序，可以得出整体热力参数，进而得出气动参数和几何结构参数。-OK ge90 basic engine parameters (altitude, cruise Mach number, air flow, thrust and series), run the program, you can give an overall thermodynamic parameters, and then draw aerod

一个实现了对BMP图像进行基本图像处理的程序,包括图像几何变化-An implementation of a BMP image for basic image processing procedures, including image geometry change
