According to a new system-nonlinear circle-linked, design the controller through the nonlinear feedback to study the problem of chaotic anti-control .The proposed method need not estimate the Lyapunov function of the chaotic system, and can dra-matically reduce the compu-tation. Numerical simulations show the nonlinear circle-linked system can track the given chaotic system fast and efficiently, fully demonstrated the superiority of the nonlinear circle-linked system.

Based on the analysis of the current situation of Advanced Mathematics in Independent Colleges,this paper offers some guidance and objectives aiming at reforming Advanced Mathematics in Independent Colleges.Performance on Advanced Mathematics construction is also introduced.

In vocational training of the students practice ability is the critical content of completing the talent training objectives,and also one of the factors to consider of the talent training amend programme.Combining with actual situation and the relevant professional needs of society,thinking about the amendment of higher vocational students training,and made a number of amendments.

In this paper a simple and convenient method finded the solution when the index is one a(fuzzy) relation non-deterministic equation have been given.

The fundmental properties of a subidentity matrix and subdiagonal matrix are preliminary presented,and using the properties a necessary and sufficient condition that a square matrix is equivalent to a subdiagonal matrix is given in this paper.
