摘要：
On the base of dimensional increment precise integration method, the block-matrix was computed. The method in the paper was further improved to reduce the dimensions of the matrix and realize the simplified computation when considering the characteristics of non-homogeneous items. Meanwhile, it can keep the existing merits of dimensional increment precise integration method. Numerical examples show that the method presented can maintain accuracy of the calculation and improve the calculation efficiency. So it will be of great advantage in dealing with large-scale and long time simulations.
