1·The element-free Galerkin method(EFGM) is improved with partition of unity quadrature(PUQ).

使用单位分解积分，对传统的无单元伽辽金方法进行改进。

2·The partition of unity method (PUM) and Level Set Method (LSM) are briefly introduced in sections 2 and 3, respectively.

第2和第3节分别简要介绍单位分解法和水平集法；

3·An efficient algorithm for implicit surface reconstruction for large-scale scattered data was proposed based on the combination of radial basis functions and partition of unity.

把径向基函数和单元分解原理综合起来，提出一种大规模散乱点云的隐式曲面快速重构算法。
