On the basis of the conclusion above, the nonlinear weak controllable vectors can be obtained, which compose the second class of weak controllable matrix, by means of matrix transfermations of the first class of weak controllable matrix. Furthmore the second criterion of weak controllability, accessibility and strong accessibility, which is more standard, more succinct and more practical, is obtained. On the basis of the first criterion and the second criterion, several important problems about nonlinear controllability are discussed, which include 1 local controllability; 2 three classes of local controllable decomposition, separately by means of local coordinate changes in the neighborhood of a nonsingular point, a point on a singular surface or a designated point x〓 with a designated input u〓; 3 the character of controllability of the ith state variable x〓 in different controllable areas and their boundaries.

First, on the basis of the theory of fairness and efficiency in tax, expense deducting is analyzed referring to the juristic principle, which provides theoretical basis and reference for the adjustment in expense deducting system. Second, by the method of induction and comparing, the author analyzes and introduces the expense deducting system in other countries or regions. Third, defects which exist in current expense deducting system of individual income tax are demonstrated. At last, connected to the reform of patterns of individual income tax, relative suggestions regarding to the adjustment of expense deducting system in our country are put forward, which is adopting mixed tax jurisdiction. The two patterns of family tax and individual tax exist at the same time and family tax should be prevailing. These two patterns can be chosen by taxpayer voluntarily. Referring to the methods in other countries and regions, the items and standard of expense deducting of individual income tax should be improved.
