The cognition on Italian neutrality during World War Ⅰ;

Switzerland choosed neutrality and implemented a flexible neutral policy based on the various historical and realistic factors during World War II.

The USA government took the same foreign policy in two world wars,that is,from the initial neutrality to a member of the later wars.

Guaranteed cost control for a class of nonlinear uncertain neutral systems with mixed delays;

T-stability of the Euler-Maruyama method was studied for stochastic delay differential equation of neutral type.

In this paper, the oscillation for a class of impulsive neutral parabolic partial differential equations is investigated.

To predict accurately the section of rolling piece,based on Markov Algorithms for rigid plastic material and adopted rigid plasticity finite law,the present thesis analyzes the flowing metal in slitting pass and thinks that the metal particles in slitting pass approximately move to both sides along the neutral surface and form the forced spread of the rolling pi.
