The Algorithm of Simplex Integration in Three-Dimension and Its Characteristic Analysis

An algorithm of integration written by C++ language are proposed based on the analysis of simplex integration over a polynomial expression in three-dimension, and the calculational procedure for simplex integration is described with concrete examples in t

在对三维多项式表达式的单纯形积分进行分析的基础上，提出了一种用C++语言编写的积分算法，并结合具体实例描述了单纯形积分的计算过程。 最后一个单词“in t”似乎不完整，如果还有遗漏信息，请补充完整后继续提问。
