Through analyzing the material movement process of the self-synchronization vibration conveyer for dual-mass based on the material slippage theory， the movement of conveyer and material stationary response were obtained on the basis of subsection establishing and solving the dynamic differential equation. The influence of conveyer frequency， material mass， friction coefficient and vibrating direction angle on the speed and displacement of material movement were discussed by numeric analysis， then the results were verified by the numerical simulation. The result shows that there exists linear relation between slip acceleration of material and vibration conveyer in single horizontal direction. The material mass has no effect on material movement. The material transportation speed and displacement of reverse slide will increase with decreasing of the conveyer frequency. As the friction coefficient increases， the material transportation displacement， time of reverse slide and average speed will increase. The material transportation displacement， time of forward slide and average speed increase along with the vibrating direction angle increasing. [ABSTRACT FROM AUTHOR]

An IP tunnel-based redirection scheme was proposed to solve the problem of routing information interaction between ForCES system and the external routers. It makes that issued process of the routing table in ForCES control element transforms to an attribute configuration operation of the logical functional block. The practice covers the core knowledge in some courses like " Computer Network" etc. It is proved that this experiment has a strong designability and comprehensiveness. And it is suitable for senior undergraduate of teaching of network engineering. [ABSTRACT FROM AUTHOR]
