To improve performance of Chinese processing applications, we must change this situation, thoroughly think of the linguistics foundation of Chinese processing, and work over linear-grammar that suits to process word neighbor-ship in Chinese by computers. We have gotten many original research results as follows: We introduced the concept of simple-phrase and the method to identify them; We also introduced a smoothing method, which greatly relaxes the sparseness problem in statistic method, based on the similarity of words according to linear dependence of them, and introduced a person-name recognition method based on reliability and a method to recognize new word based on multi-features.

In the research to demand of International reserves,first, according to the affective character of demand to transition of International reserves, choosing the decision theory of Markov and dynamic transition equation as basic model, the paper has set up two transition methods--- stationary matrix and dynamic matrix, the later matrix has improved the sensitive reaction to time and velocity. Second, combining with knowledge of linear algebra, the paper has analyzed and testified the positive associated relation between transition matrix elements on main diagonal and the convergent speed of system, and explained why international reserves transition embodies the character under new situation and why the transition process can be accelerated by the strike of international idle money. Third,on the quantitative calculating to elements of transition matrix,referring to multiplication theory and decomposing-composing method of system, the paper has transformed main three-factor deciding confidence of international monetary into detail modulus by comparing analysis measure,now the matrix has been decided.
