moving least-square approximation method

And then an new iterative method is presented to solve the nonlinear equations system obtained from moving least-square approximation.

之后，借鉴牛顿法、平衡法和摄动法对由移动最小二乘法得到的非线性代数方程组提出了新的求解方法。

It used the moving least square approximation as a trial function, and used the weighted function of the moving least square approximation as a test function of the weighted residual method.

这种方法采用移动最小二乘函数来近似解变量，并且采用移动最小二乘近似函数的权函数作为加权残值法的权函数。

Based on the generalized moving least square method, a new Element-Free Galerkin (EFG) double-variable approximation is applied to dynamic characteristic calculation and analysis of Euler beam.

以广义移动最小二乘法为理论基础，将同时考虑挠度和转角双变量的无单元法运用于欧拉梁的动力特性计算与分析。
