峰值电流型开关变换器的建模与仿真，通过simulink平台，方便设计人员对开关电源的原理进行理解。(Modeling and design of peak current mode switching converter)

这是个用Java语言编写的游戏小程序。故事的起因是：冷战虽然结束了，但又出现了来自太空的新敌人UFO，它们可以干扰自动导航的导弹系统，所以你得亲自标准目标，射击。不能让它们登陆，否则你就输了！希望你从中可以学会如何用Java来编写此类游戏。-This the Java programming language of the game small programs. The causes of the story : Although the Cold War is over, but from a new enemy space UFO, they can interfere with the automatic navigation systems, so you have to personally standard target shooting. They can not allow the landing, otherwise you lose! I hope you can learn from how to use Java to prepare such games.

说明：  用三个按键控制pwm输出 key0控制是选着显示/改变频率或占空比 key1控制增加 key2控制减少 数码管显示频率或占空比 频率单位默认Hz（500-20KHz） 占空比范围（0.1-0.9）(Control PWM output with three keys Key0 controls display/change frequency or duty cycle optionally Key1 controls the increase Key2 controls are reduced Digital tube display frequency or duty ratio Frequency unit default Hz (500-20khz) Duty cycle range (0.1-0.9))

This notebook numerically integrates the Friedman equation (18.78) to find a homogeneous isotropic cosmological model.

Delphi基于Excel组件的图表生成实例，Excel chart，点击按钮就会打开Excel表格绘制出图表。

国际上著名的cdecl的超级简化版 ， 也算是一个另类的中文版吧。。。可以将C 语言的声明翻译成中文哦！！！例子（上面一行是输入，下面一行是输出）：int a标识符a是int型int a[]标识符a是int型的数组int *a[]标识符a是指向int型的指针的数组int *a()标识符a是返回值为指向int型的指针的函数int (*a)()标识符a是指向返回值为int型的函数的指针
