Through combining the actual condition of the piping layout of offshore platform and calculating the unbalance force caused by pulse,it confirms the method is the best.

Unsteady numerical simulation and analysis of the flow fluctuation in the Roots blower;

The characteristics of gas solid jet are researched and the characteristics of gas\|solid jet fluctuation are proved by means of Rescaled Range Analysis.

The effects of fluidization number, injection velocity ,particle mean diameter and static bed height on jet fluctuation are discussed.

The method of adopting the two windings with a phase shift of thirty electrical angles is presented here,it is used to reduce the ripple for the condition that ripples of the out voltage of rectifier generator used in the area of aviations and airspace is much bigger.

The torque-ripples of the double-salient motor are inevitable for its double salient structure and switch power source.

This paper introduces the control principle of the direct torque control system of an asynchronous motor,and proposes a new strategy to solve the problem of the large torque ripple and current ripple.
