一键清理系统垃圾文件,一键清理系统垃圾文件-A key to clean-up system junk files, a key to clean-up system junk files

在普通的表达式中，符号是位于运算对象之间的，而在波兰表达式中，运算符号位于参与运算的对象之前。 波兰式在计算中的价值在于它不需要使用括号，之所以如此是由于波兰式的操作符的先后顺序是明确的。 -In the general expression, the symbols are located in between the operands, while the expression in Poland, the computation involved in computing at Symbol before the object. Polish-style in the calculation of the value is that it does not require the use of brackets, the reason for this is due to Poland-based operator of the sequence is clear.

模拟一个动画弹球的垂直弹跳的动作，每次衰减为上次高度的0.9，考虑重力加速度。-An animated simulation of a vertical pinball bouncing movements, each attenuation for the last time a high degree of 0.9, consider the acceleration of gravity.

包含数十个经典算法的C语言实现，绝对经典！-Contains dozens of classic algorithm for the realization of the C language, an absolute classic!

一个Undo和Redo的例子，值得研究--An example of undo and redo,worth discussing

基于队列中挂起的任务数自动调整线程数，使用策略来提供灵活性和可扩展性-It can auto-adjust threads basing on queue-hanging up,which also use strategies for flexiblility and extensibility.

应用背景使用4路AD中的1路检测外部模拟量输入，显示0-255数值  DA输出电压用LED显示，主要用于检测环境光线，光线强，则灯亮度小，以保证整体光强稳定在一个范围这种思路和用法主要用于自动调光，可以根据环境亮度自动调节，从而达到节能最大化，关键技术该代码使用4路AD，采用I2C协议，用于调节光线，然后再用数码管显示光强，非常直观看出其变化。代码移植性强，直接调用库函数，非常方便。
