There is lack of efficiency and benefit in the Chinese pretrial procedure for which the judicial resources are not properly set and the rights of both the suspect and the accused are violated to some extent.

In this paper,pressure equalization process,adsorption temperature,oxygen flow rate and the size of oxygen generation machine have been changed to get the effect direction and degree of them on exergy efficiency and oxygen recovery in miniature PSA oxygen generation system.

Exergy losing of every equipment and the exergy efficiency were calculated.

Some effect factors on the exergy efficiency of cycle and the exergy loss of components such as compression ratio of compressor,isentropic efficiency of expander,cold energy loss,and temperature difference in heat exchangers are discussed.

In order to enhance the the service efficiency of laboratory housing,many universities are carrying on the laboratory housing management reform.

In this paper, based on brief analysis of the situation of human resource in China, through qualitative and quantitative methods, the research on service efficiency and economic benefit of human resource in China is made.

Using the shortage of teacher resource,the real situation of low service efficiency and its features in Inner Mongolia as a logical starting point,this paper evaluates teachers service efficiency with real data.

The fertilization efficiency should be raised and thus avoid mistakes from its application.
