Study on effect of heat treatment on residual magnetic intensity;

Study on the determination of residual strength for expansive soil;

The result shows that the installation of bolts can effectively enhance the peak and residual strength of the bolted rock body and that bolts strengthen the strength of residual of the rock body more than they do the strength of its peak Moreover,with the increase of t.

By the simulation test, it is proved that the function of rock bolt is to raise the residual strength of broken surrounding rock around roadway, and the broken surrounding rock is made into a reinforced arch.

Discussion on magnetic induction and magnetic field strength;

Based on the expression of the damping force,the effect the gap,length,radius,magnetic field strength and velocity of piston on damping force is analyzed.

Controlled slowdown of equivalent light speed and its applications in measuring magnetic field intensity;

On the role of magnetic field intensity effects on the discharge characteristics of Hall thrusters

The results showed that in specifically range the variety of electric current intensity and frequency remarkably affect the magnitude of magnetic field intensity.

This paper points out the deficiencies of the diesel rock drill’s ignition system,such as the flywheel demagnetizes and the field strength is low when it is magnetized-thus,the flashover of spark plug is not enough strong,diesel rock drill’s starting is in difficulty and so on,then gives a method to improve the flywheel's instructure and the performance of the engine start is improved obviously.

Differences in degree of the influence of shape and weight of Ni-Cr alloy and different field strength on MRI artifact was compared.

To compare the relationship between the artifact of different fixed prosthesis and field strength,scanning sequence.
