First of all, the evolutionary game model of this system is built, according to a population and determinately dynamic function in evolutionary game theory, and quilibrium structure and effect factors of the evolutionary system are analyzed. Next, the evolution quilibrium characteristics of investor behaviors in China's securities market are researched as a demonstration, and the reasons why noise traders become popular in the process of investor behavior evolution are explained, based on its evolutionary mechanism. Moreover, the influences of investor behavior evolution on share market's fluctuation are researched through setting up its noise trade model. When noise traders are dominant in securities market, price discovery function and resource configuration effect are also analyzed. Finally, when noise trade become popular, the shortage of some policies, such as, enlarging institution investor and short sale is explained, and some good suggestions are provided according to former research results.

The noise frequency modulation signal was particularly analyzed. The Fokker-Planck equation of noise frequency modulation was presented and the Motion-Group Fourier Transform was used by converting the partial differential equation into the variable coefficient homogenous linear differential equations. Then the solutions were given by using the peano-baker series. So the probability density function of noise frequency modulation in the filter was given. On the basis of the probability density function the stochastic resonance of noise frequency modulation signal is analyzed.
