Both the theory of regulatory state and theory of incomplete law construct the framework of independent regulatory commission,however,neither of them can answer the question why the traditional government is not appropriate to assume the regulatory function.

The present paper introduces and expounds Theory of Reluctance by Fredrich Engels in his Frederich Engels ANTI-DüHRING and points out that such a theory provides the new train of thought and standard for us to know the position and role of national ownership in market economic system.

Exact solution to free vibration of each mode of the rectangular plate is obtained according to the fixed point theory of partially ordered space.

Finally, based on fixed point theory, the existence and uniqueness of the classical solution to the integrodifferential equation is proved.

In the paper,by using the fixed point theory and differential inequality technique,we study the existence and global attractivity of almost periodic solution for the neural networks with S-type distributed delays,and give the sufficient conditions of the existence of almost periodic solutions and global asymptotic stability.
