Through the stressed analysis to slippage transition interface,it shows that when the sum of pile angle θ and rolling angle α approaches 180°,material is likely to roll from one side of helical to the other side.

Using a fuzzy decision to realize smooth transition in a variable structure control system;

It can obtain the aim to enhance the utilization efficiency of the equipments and save the investment, and realize the smooth transition from 3.

Based on the up to date IPv6 transition techniques, this article presented a new technique of smooth transition from IPv4 applications to IPv6 applications, which is socket API Agent in the host technique.

Connecting with the practice of the project of the intake and drainage system of Guangdong s Huizhou Power Station,and through the experimental study on the physical models under constant and instant work conditions,this paper analyzes the hydraulic characteristics of the transition fore bay from the intake to the pump room of the power station.
