Through tests such as the valve closing time,RSV\\'s opening dynamic and OPC characteristic,and valve delay rate etc,it is indicated that a good static characteristic is verified and the unit\\'s database improved,which has established the foundation to guarantee the unit\\'s operation smoothly.

The causes leading to swaying of servomotor for double extraction steam turbine in Anqing Petrochemical Thermal Power Plant have been analysed from some main aspects, such as setup of system parameters, delay rate of the servomotor, and closed loop control of the double extraction steam turbine etc.

The friction between sliding valves may influence the stagnant rate of steam turbines.

This article describes mostly the influence of vertiginous rate "δ" and stagnant rate "ε" for turbine s velocity "n" and power "P" in different working situation, it is important to choose suitable "δ" and "ε" on turbine s economic-safe running.

Aim To evaluate the correlation between the swelling equilibrium quantity (S eq), dissolution rate and amino g roup content which were used to estimate the degree of gelatin crosslinking, and the factors which influence the crosslinking, and to investigate the crosslinki ng mechanism of delayed dissolution of soft capsules.

Objective:To investigate the dissolution stability of Ephedra extraction soft capsules and the influence factors thereof and to explore the mechanism of delayed dissolution of traditional Chinese medicine soft capsules.
