The traditional distinction based on the matrix attribute reduction algorithm analysis, for distinction in the matrix "repeat" Too many elements, these "duplicate" elements not only in solving attribute reduction in the process does not work, But also reduce the time efficiency by improving the shortcomings that distinction in the matrix structure in the process of using Proposition calculus in the absorption of the law removed the distinction between the functions of the non-functional "repeat"element, a property Reduction of improved algorithm RADM, improve the efficiency of the attribute reduction.

通过对传统的基于区分矩阵的属性约简算法进行分析后，针对区分矩阵中"重复"元素过多，同时这些"重复"元素非但在求解属性约简的过程中不起作用，而且还降低时间效率这一缺点进行了改进，即在构造区分矩阵的过程中，利用命题演算中的吸收律去掉了在区分函数中不起作用的"重复"元素，提出了一种属性约简的改进算法RADM，提高了属性约简效率。

The present method is applied to two-dimensional potential problems and the corresponding discrete equations are derived. Because the shape functions so-obtained possess the Kronecker delta property, the essential boundary conditions can be enforced as the FEM; furthermore, the Heaviside step function is used as the test function, there is no domain integral, and only a regular boundary integral is involved.

因为滑动Kriging插值方法构造的形函数满足Kronecker函数性质，所以本文建立的改进的无网格局部Petrov-Galerkin法可以像有限元法一样直接施加边界条件；由于采用Heaviside分段函数作为局部弱形式的权函数，因此在计算刚度矩阵时只涉及边界积分，而没有区域积分。

The solution for the non-stationary system is obtained through the stationary disturbed system.
