The ball-off and hydraulic releasing tools are used in oilfield, but it can not transfer the moment of torsion and limit their applied range.
This paper introduces current situation of vibration damp control for vehicle suspension system, principle and feature and applied range.
As the development of the cross subject, the good technical system in physics, the complete research system and the integration of various techniques were needed, promoting it into greater utility and wider applied range.
The methods, technology and the applied range of shear wave exploration are summarized.
It also extends the applied range of YIG single crystal fiber and promotes its research motivation.
