Study of agro-environmental geology system and its state evaluation base on information entropy theory;

After the analyses of essential problems of WSN,this paper brings forward an Active QoS Mechanism(AQM)based on middleware,which is application,state and role-oriented,and some key points of AQM which includes the thinking of design,infrastructure,procedure of working,information exchange and state evaluation are studied.

Whole body vibration condition evaluation of aero-engine on grey correlation degree;

The uncertainty and incompletion of evaluation evidences are fully considered, qualitative and quantitative evidences are integrated and the acquisition and transformation methods are put forward based on constructing multiple-attribute decision-making tree for condition evaluation.

Based on grey space relationship,a grey model, for condition evaluation of auxiliary equipment in power plant,is built.

Research on constructing restriction relation model of organization operational status evaluation;

On the basis of establishing a status evaluation index system of steam turbine DEH(digital electro-hydraulic) control system,proposed was an extensible evaluation method.
