Based on the kinetic equation of saponification of ethyl acetate, this paper discusses how to get the reacrion rate constantby graphic differential of the graphy that shows the relation between electrical conductance value and time of the reactionsyste

By means of the determination of the saturated-vapoar pressure of the ethyl acetate an ex-plicit function describing the temperature-dependence of the gasification entnalpy is obtained through differential-graphic method,Some related problems is also discussed in this article.

On differential analysis of the Solow model and draw from certain experience;

The differential analysis influnced by taxation of profits in enterprise;

The different method and iteration algorithm are used in the model,and an underwater acoustic method is given to monitor the line style in real time.

Multi-kernel nonlinear diffusion model for denoising based on image decomposition;

Research and Application of Image Decomposition Based on PDE;

The author presented the theoretical basis of wavelet transform and the processing of image decomposition and reconstruction, then discussed the method of image compression using the wavelet transform in the Matlab and analyzed how to choose the wavelet base for the aim.
