No matter how fast the dash men run at the beginning of the race, they have difficulties in achieving good results because of their reduced speed in the last distance.

Study on and Realization of Precision Controlling Way when Using the After Interpolating Speed Controlling in Interpolating Process;

The optimal control of aeroengine acceleration and deceleration processes is deeply investigated.

The idle deceleration process simulation of the engine is studied by using the CFD(Computational Fluid Dynamics)software and virtual prototyping software,and the deceleration process of the engine in different blow-by gas leak is stimulated,and it is validated by real-vehicle experiment.

In the speed skating competition of middle and long distance events,the speed skaters\' deceleration in the rear distance has become a bottleneck of Chinese speed skating development.
