In this paper a discretization algorithm based on importance of cut point.

提出一种基于断点重要性的离散化算法。

To carry out discretization, a PDE is written for a given point in space at a given time level.

为了解决离散化问题，偏微分方程是针对某一特定点的空间在特定时间轴。

By introducing the concept of "nihility point" and the method of "spherule bounding" in the algorithm, we have simply and effectively realized boundary discretization in 3-d space.

这种算法采用“虚点”概念，按照一定的规则用“小球跳跃法”简单而有效地实现了三维场域边界的三角形离散。
