根据对真空蒸发镀膜的分析，在40×40的范围内分别蒸
发：1000、5000、10000、20000、30000个粒子。
利用2维数组记录每个点的粒子数。
初始粒的横纵坐标为0～40的均匀分布。
能量为（15，3）的正态分布。
在基体表面自由行走时损失1的能量。
若该点有粒子，即与其他粒子相遇时损失3的能量。
由低处向高处扩散，每扩散一层，损失4的能量，由高处
向低处扩散，损失3的能量。
当粒子的能量小于等于0时停留下来，该点的粒子数加1。
临界核的尺寸为10个粒子。
根据每个点粒子个数的不同，以不同的灰度显示这些点。
点越亮，则表示该点的膜越厚。
以图形方式显示粒子初始能量的正态分布情况(Based on the analysis of the vacuum evaporation coating, respectively, in the range of from 4040 evaporated: 1000,5000,10000,20000,30000 particles. each point using 2-dimensional array to record the number of particles.
