Based on the shuttle car running independent drive mode,built a mathematical model between the tyre deflection angle and the steering radius,then make use of the mechatronics to analyse the implementation of the steering differential of the shuttle car and put it into practice.

It was found out that the worpiece bending is the comprehensive result of forwards slip difference and velocity difference of top and bottom surfaces of workpiece.

The velocity difference was used as the evaluating standard in alignment continuity,the velocity dispersions under different design velocity were calculated according to possible velocity calculation formula,the relationship between velocity dispersion and plane curve radius was found.

Design of synchronization running control system using speed difference circuits of dyeing and printing union machine;

According to a large quantity of experimental results, the main factors(thickness of liquid-loop,speed difference)that influenced sludge dehydration effect were analyzed in the present paper.

Multiple velocity difference model and its stability analysis;

Property analysis of the multiple velocity difference model;

The velocity difference of air in two channels of the conventional dense-dilute pulverized-coal concentration burner is 6-8 m/s,which impacts combustion stabilization,burning efficiency,and NOX emission.

Depth error in depth migration profile isn't equal to velocity error, sometimes it is twice as many as velocity error.

For a long time,the analysis of the velocity error almost were rarely quantitative,and only valid to the simple geology condition.

In obserations of the Earth s atmosphere with the GPS radio occultation technique,some factors such as the position error of GPS and LEO satellite,velocity error,clock drift,and observation error of carrier wave can bring error to the retrieval atmospheric parameters.
