The results show that after addition of new biological fluidized media,the biomass and kinds of microorganisms in the SBR are increased considerably,and the mass transfer condition is improved obviously.

To evaluate the effectiveness of investment decision for manufacturing systems,the system input was decomposed as information flow,material flow and energy flow while the system output was decomposed as stability,quality of self-organization and integrity,all of which were expressed separately by certain measurable parameters.

In view of the shortcoming in the former study on dynamic measurement technology of material flow on belt conveyors in manufacturing systems, the dynamic measurement theory of the material flow is studied systematically in this paper.
