利用随机数产生红色液体从墙壁上向下流动的效果-Using random number generator red liquid from the wall the effect of downward mobility

用两个函数图形来仿真蝴蝶飞翔的过程。附加了随机数的产生。-In this simulation we give life to the flight of butterflies using two parametric equations of the known "butterfly curve". The flight is simulated by drawing symmetrical wings. The journey undertaken by both butterflies

用二维随机数生成二维高斯分布随机表面，可调整均方差、相关长度等参数-Generate a two-dimensional Gaussian random numbers using two-dimensional distribution of random surfaces, adjustable both variance, correlation length and other parameters

本程序实现随机数的产生和在相同调制方式下功率谱比较-This procedure realize the generation of random Numbers and in the same modulation mode power spectrum
