Psychological Study towards Influence form Media Violence on Juvenile Delinquency;

Evaluating the hole stabilizing performance of silicate-based drilling fluid with pressure transmission test;

The formulas of calculating extraordinary low permeability and semipermeable membrane efficiency of shales through pressure transmission technique were deduced.

On the basis of analyzing the principle of shale membrane efficiency testing, formulae are derived for calculating the membrane efficiency by using pressure transmission technique.

Bolt support, a kind of normal-position reinforcement technology, fulfils such functions as framework, sharing burden, stress transmission and diffusion, which make it possible to combine the bolts and soil into compound soil body and to increase the cementation power and intensity of the soil body.

In this paper,the principle of gravitational stress transmission in blocky rockmass is researched.

By qualitative mechanics analysis,model tests,dynamic loading tests,and numerical calculation and analysis,it is showed that the stress transmission in stratum is closely related to the relative stiffness of the medium,and a new concept棗the concept of stress transmission is proposed.

Study on stress transfer between soil nail and surrounding soil;

Interfacial stress transfer behavior of single-fiber composite under the effect of mechanical and thermal loading;

Mechanical propertys of fiber composites largely depend on stress transfer of fiber and matrix.

Effects on internal force transmission and reinforcement roles of structure and shape of geogrid;

For the great importance of constitution and performance of beam joints of concrete filled tube col- umns, a nonlinear finite element analysis has been made using ANSYS for single beam joints to study the stress distribution and internal force transmission in the joints under vertical symmetrical loads.
