Abstract： In this year， the ressearches of our project are carried out facing with four key scientific problems. All the participants worked actively， and the research plans are successfully archieved. Especially， some important results have been obtained. Presently， there are 58 scientific papers published in the high-tier journals， including Phys. Rev. Lett.， Phys. Plasma， Phys. Rev. E， EPL， PloS One and so on. Two monographs are published with the supports of this fund. These results includes. （1）the RT instability and interfacial fluid instability and various instabilities in laser-plasma interaction are widely studied. The quantitative characteristics of the pattern evolution， the comprtition between various instabilities as well as the effects of different environmental factors are systematically investigated. Some schemes to control or suppress these instabilies are proposed. （2）The theoretical model about how the localization induces the catastrophe is proposed， and the related experiments on the fragile materials are carried out. Some interim results are obtained. The primitive 3D ocean equation with fast oscillative stochastic forces are also studied. The existence and convergence under certain conditions are proved. Besides， some important studies on various kinds of nonliner partial differential equations are also carried out. （3）There are key progresses on the fundamental theory about Arnold diffusion. A series of characteristics about asteriods are carried out， which provides sufficient preparations for the further research on the precise model of solar system. There are also many valuable progresses on the design and control of deep-space vehicles. （4）There are systematical studies on the p53-centered network regulation， transcription terminator regulation， and the regulation on the mRNA of target genes by sRNA. Some important results are obtained. The coding of new-version CVTree3 is finished， and would be released. Besides， among all the students who participated into this project， there are 15 ones who received their doctorate degrees and 12 ones who received their master degrees. One participant received the National Science Fund for Distinguished Young Scholars.
