In this paper, material properties of the segment of the porous metal-bonded diamond grinding wheel were researched by finite element simulation. Segments were manufactured according to the design result and their elastic modulus was measured. The key points are as follows: The influence of the porosity on the elastic modulus was analyzed through a finite element method. In the FEM model, the design variable only includes the porosity, and the tetrakaidecahedron model is applied as the microstructure model of porous metal matrix. The corresponding porosity was decided in order to meet the requirement of the elastic modulus.

本文利用有限元软件对多孔金属结合剂金刚石砂轮节块的材料性能进行了数值模拟计算，依设计结果制备了节块试样，并测试了节块的弹性模量，主要内容有： 1、充分借鉴多孔材料结构设计和分析的方法，以十四面体模型为多孔金属胎体的微观结构模型，以孔隙率为设计变量，通过有限元分析，计算出满足一定弹性模量要求的多孔金属胎体的孔隙率范围。

On the base of probabilistic and statistics results of joints and cracks, the Author modifies Block Theory. The sliding probability of Key Block is I A RSTR A CT F2 ? 5.It is put up forward that GM(l,1) Model to predict Amount of rainfall, and Markov Chain to modifY GM( 1,1 )predicting result, and then a theoretical predicting Model of amount of rainfall is firstly built. This model is applied in a situ example. It is proved that the model is very useful to predict amount of rainfall ,when ordinal array of Amount of rainfall changes in unexact index rule.
