This paper mainly introduces the non-linear characteristic analysis of the air spring of large flow air filled safety valves in powered supporters, non-linear error and the influence caused by the non-Linear on the dynamic characters of safety valve system.

Comparative experiments were carried out to study the effect of the adsorption heat on the charge and discharge performances of a hydrogen storage system.

Study on the Aeration Performance of LHJ Flotation Column;

The circular centrifugal flotation cell has many originalities on the pulp aeration, air bubble mineralization, air pulp flow format in the ring shaped tank of the cell, feed method ect, due to the results of fluidics and turbulence and the action of centrifugal and gravitational force ect.

The“dead zone”of particle located at the bottom of annulus can be eliminated,and the effectiveness of solidgas contact,mass and heat transfer can be improved by introducing an auxiliary(aeration or fluidization)fluid into the annular region through a distributor.
