平均推力 meaning in Chinese

average thrust
mean thrust

The main characteristic of pulse plasma propulsion in water is great propulsion in moment , whose average propulsion is smaller . so it may be useful for side face propulsion of ships in static state as the assistant propulsion
水中脉冲等离子体推进的主要特点是瞬间推力大，但由于它所产生的平均推力小，更适合用作助推力，可实现船舶的定向和准确停靠。
In order to imitate tune tail fin better , a flexible fin only in chordwise is considered . results shows that flexibility can increase the propulsive efficiency and cause small decreases in the average thrust compared with a rigid caudal fin with similar motion . next , a comparison between the rectangle fin and the lunate fin is given
为了使数学模型更贴近生物模型，本文又将尾鳍处理为只考虑弦向变形而不考虑展向变形的柔性体，两者对比的结果表明，柔性翼使得平均推力减小，但是，对具有相同推力的柔性翼比刚性翼具有更高的效率。
