加权Sobolev空间的非奇异坐标变换

Nonsingularity Coordinate Transform of Weighted Sobolev Spaces

利用加权Sobolev空间中的非奇异坐标变换和仿射变换，建立了从有界集到有界集的可逆坐标变换，同时，讨论了有限单元的仿射变换和存在扰动的等参变换的性质。

Reversible coordinate transformation is established from bound set to bound set by making use of nonsingu-larity coordinate transformation and affine transformation in weighted Sobolev spaces and at the same time, the characteristic is aslo discussed with affine transformation and perturbative oparametric of finite element.
