Based on the character that hidden layer wavelet function of wavelet networks can adjust scale factor and shift factor to affect output of networks,the least disturbance algorithm adding scale factor and shift factor is proposed and it can calculate the dynamical learning ratio to improve the stability and convergence of wavelet networks.

The learning algorithm which calculated dynamic learning ratio based on least disturbance was deduced to compensate sensibility.

In order to solve these problems,a novel minimum interference routing algorithm based on the channel resistance is presented.

This paper develops a new method to study the Hopf bifurcations of periodic orbits in three-dimensional, time dependent perturbation of planar Hamiltonian differential equations, and gets a series of concise formula to simplify the Hopf bifurcation conditions by some mathematical skill and subharmonic Melnikov method.

First of all,the paper defines heat economy analysis as the means of big disturbance theory which combined with turbine varying condition and of small disturbance theory which is with the method of linearization.

Based on the combination of the matrix equation,the small disturbance theory and the fundamental equations of thermal efficiency analysis,the internal work and thermal analysis equations are educed,and then the quantitative analysis equations for the system energy saving analysis are built.
