The interdependent theory explains the necessity of the coordination, the game theory shows the possibility of it, and the theory of uncertainty answers the realistic market failure.

In this article, we turn to the international relation theory: interdependent theory, neo-functionalist and international mechanism theory for help to analyst its process and try to guide it for its action.

This paper applies the resource dependency theory proposed by Pfeffer and Salancik(1978) to indicate the different levels of resource dependency and power control between manufacture and service industries during different industrial development phrases.

Based on the similarity theory,two degrees of freedom flight test platform was designed to simulate the helicopter,then the platform was taken as the research object,and the Lagrange-Euler equation and the equivalent moment method were used to derive the system dynamics model,and the physical parameter was estimated.

Some useful design formulas are obtained by the application of the similarity theory and the modular design method.

Talking the order similarity as the example,using similarity theory to explain different errors is in.

Based on linear matrix inequality approach,the consistency theory on sector pole index,steady variance index and H-infinity constraints is set up,and the ranges of consistent indices are analyzed in details.
