We show that Jordan multiplicative bijective maps on prime operator algebrasmust be additive. As its application, we show that every Jordan * multiplicative bijec-tive map on every factor C~* algebra is a C~* isomorphism or a conjugate C~* isomorphism,in the special case of B, it must be a *-isomorphism or a conjugate *-isomorphism.We also prove the additivity of Jordan multiplicative bijective maps on nest algebras.

The adjoint operator method and the theory of normal form are used to investigated the normal forms in the four dimensional nonlinear systems with cubic nonlinearities. We give two methods to compute the normal form for the four dimensional nonlinear systems. The corresponding Maple programs are also given in the appendix. The results obtained in this dissertation have a completely agreement with the results obtained in other papers.

Taking the administrative villages as units, a comprehensive and detailed survey was made to attain the rich and reliable data, including the information about the status of the land use, the relationship of the land supply and demand, the living standards of farmers and the minimum of urban resident living guarantee and so on. Then the estimating system was established. Afterwards, basing the survey and the system, the character of each unit was transfer into data. And, utilizing the frequency law, the whole county was divided into four expropriation land blocks. The area was measured and the map, showing the differences between blocks, of the Arable Land Blocks for expropriation of Siyang was protracted by the method of GIS. Finally, the land expropriation price is calculated by agricultural land economical function compensate method and urban construction land criterion price avulse method, then the price was tested by expropriation case comparison method. It is beneficial not only for protecting farmers rights and interests, but also for link up with the current land compensate standard, so this way to calculate the land expropriate price is more reasonably.
