Based on the compatibility compression-field theory and the truss-strut model, a thorough investigation of the shear strength of the simply supported rectangular beams under concentrated forces and uniformly distributed load was presented, which takes into account the .

The Modified Compression Field Theory(MCFT) was presented by Vecchio and Collins based on experimental study which was used to analyses the reinforced concrete element under shear stress and principal stress.

Coordination Theory and Its Application in Mobilization of National Economy;

Its functional architecture was constructed based on coordination theory.

The whole framework of coordination theory of electric power system optimal dispatch considering security and economics is established, and the coordinative dispatching mechanism and model at 7 aspects of space scale, time scale, power production link, controlled object, security and stable control strategy, optimized goal and open impartial equitable dispatch are presented.

It is found in this paper that the field synergy principle proposed by Guo and his co-workers for enhancing convective heat transfer is also applicable to the analysis of pulse tube refrigerator(PTR) performance.

The field synergy principle was applied to the cooling system of the generator rotor with rotating coordinate system.
