In this study, it is the first that Viticis Fructus (VF) was used as raw material for extracting total flavonoids using ultrasound-assisted enzyme extraction (UAE) method. Response surface methodology employed to determine optimal parameters. The conditions were follows: 60 % ethanol solution extract solvent, material-liquid ratio of 1:25, pH value 4, addition amount 1.5 %, enzymatic hydrolysis time 30 min, temperature 40 ℃, and ultrasonic 50 min. Comparing flavonoid yield VF processed (PVF)...
This paper presents an innovative solution that is able to suppress the thrust ripple in a high-power asynchronous linear induction motor (LIM) used microgravity experiment facility electromagnetic launch (MEFEL) system. By addressing crucial need for low levels of MEFEL applications, we propose dynamic model-based adaptive controller (MAC) and enhanced quasi-proportional-resonant (PR) controller. The MAC designed compensate inherent impedance asymmetry motor. PR minimizes by eliminating...
Based on the electromagnetic field theory, distribution of thrust density along longitudinal direction long primary double-sided linear induction machine (DLIM) with plates secondary is studied. Then a novel wedge type for DLIM proposed to reduce ripple and acceleration. The influence new parameters performance researched, characteristics its plate are calculated. effects these two kinds force system acceleration compared. research suggests that structure can improve stability
End effect of linear induction motor (LIM) brings asymmetry to the inductance matrix, leading imbalance current and thrust ripples. In order eliminate imbalance, measurements calculations are analyzed in this paper. The voltage strategy is designed through parameters three-phase equivalent circuit results. calculated results validated by experiments on a prototype LIM.
