The stractures of power groups are discussed systematically by introducing generalized kernel and the constructivity theorem on a class of power group is established.
通过引入广义核概念，详细讨论了各类幂群的结构，并给出了一类幂群的构造定。

Different from the existing kernel feature extraction methods, the kernel function used in the proposed one is not required to satisfy Mercers theorem so that they can be chosen from a wide range.
与现有的核特征抽取方法不同，该方法不需要核函数满足mercer定理，从而增加了核函数的选择范围。

It is the first time to have the theorem of orthogonal decomposition, a theoretical kernel in inverse gravimetric problem, realized in practice.
