1. Therefore, tamping point earth volume deformative model and test model after dynamic compaction are researched.

2. The paper summarized the frictional sliding behavior, deformative characteristics and their changes with deformed conditions of each kind of gouge.

3. By means of calculating deformative work, the formula of rolling force has been deduced for bimetals .

4. The deformative charateristics of cementite of white cast iron during the rolling process was investigated.

5. The dislocation etch pits density(EPD) of copper single wires is related with corroded time, deformative extent and crystal orientation of material.

6. Based on the established model, the analytic resolution of transmitted and reflected coefficients is obtained when the normal incident P-wave propagates to the nonlinear normal deformative joint.

7. In this paper, through the test and study of 18 eccentrically loaded concrete filled square steel tubular stub columns, the mechanical and deformative behaviour of these members were analyzed.
