用来模拟粒子运动的。此元胞自动机需要

一种不同类型的元胞的邻居。此元胞的邻居时刻变化，因此某一个方向运动趋势，

将继续在同一个方向。换言之，此规则保存势头，这是基础的动力仿真。这种邻

居通常被称为 margolis邻居并且这种邻居通常由重叠的 2x2 块的元胞构成。在下

面的表格中，偶数步长时左上方 4 元胞为邻居关系，奇数步长时右下的 4 元胞为

邻居关系。某一特定元胞在每一个时间步长都有3 个邻居，但是具体的元胞构成

了邻居的旋转和反复。-Used to simulate the particle movement. The cellular automaton requires a different type of cell neighbors. This moment of change in a neighbor cell, so a certain direction the trend will continue in the same direction. In other words, this rule saved momentum, which is the foundation of the power simulation. This neighborhood is often called a neighbor and this neighbor margolis usually overlapping 2x2 blocks of cellular composition. In the following table, even when the step left four yuan for the neighbor cell, the odd step 4 when the lower right cell for the neighborhood. A particular cell in each time step has three neighbors, but the specific cellular composition of the neighbor　s rotation and repeated.
