易语言粒子时钟源码例程程序结合易语言多线程支持库和易语言模块GDIPlus类.ec，调用API函数实现时钟粒子的物理运动效果。 用两个物理公式伪弹性。(没有能量渐衰等) 自由落体位移公式：v=gt 物体上抛公式：h=at-4.9t^2 -Easy language particle clock source routine procedures combined with easy language multi-threaded support library and module GDIPlus class. Ec, call API function to achieve the physical movement of the clock particle effects. Pseudo elastic with two physical formula. (no energy fading, etc.) free fall displacement formula: v = gt objects thrown formula: h = the at 4.9 t ^ 2
