Application of lever theory in temporomandibular joint dislocation;

Double-acting Piston Pump with Two-step Output Pressure Driven by Hand Lever;

A Method of Resolving the Lack of Freedom for Hydraulic Fixture of Toggle-Levers with Rolling High Pair Instead of Low Pair;

In the light of 500 kV HVAC and HVDC,especially the problems of heavy line-lifting tool and very hugh labour intensity during live replacing the twin suspension insulator strings with single wire clip of straight circuit for heavy load HVDC,a built-up fork hook based on lever principle was developed instead of the taditional process,the double lifting lines.

A small lever-loading atmosphere furnace was designed.

Bayesian Analysis of Stochastic Volatility Model with Leverage Effect and Its Application;

The results indicate that Chinese stock market is largely volatile and has not reached the level of weak effectiveness,that positive and negative leverage effects appear in turn,and that the information asymmetry exists but tends to apparently decrease.

The conclusion is that the leverage effect and week effect is obvious for waving of in the Shanghai and Shenzhen stock index.

However,applying standard lever rule to transformation process with continuously precipitating of two/more phase to obtain kinetic information will cause a great error in cacu- lating transformed volume fraction.
