- It should be noted at that position each champion is applying propulsive force. 需要注意的是在这个姿态每个冠军都是在用推进力。
- Thus, the best streamlined position without any propulsive force is undesirable. 因此，即便是最好的流线型位置但如果没有任何的推进力就是不可取的。
- In both, propulsive force is derived from the reaction produced by a stream of air driven rearwards at high velocity. 这两类发动机都是靠高速向后喷射气流所得到的反作用力而发出推力的。
- The propulsive force and the active drag during swimming were measured experimentally to improve athletic performance. 为使运动员在训练和比赛中有良好技术表现,对游泳推进力和动态阻力的测量进行了研究。
- When watching Klim, one can see where there is an almost complete lack of propulsive force during armstroke recovery. 当观看克里姆游泳时，任何人都能看得出他在移臂期间几乎没有什么推进力。
- It is important to realize that the top range of race speed: minimization of resistances takes priority over increased propulsive force. 对于游泳速度而言，很重要的一点是：减少阻力要优先于增加推动力。
- They usually roll to better position limb segments to produce a more direct propulsive force, which is usually under them, resulting in better movement economy. 他们一般都会滚动到一个最佳的位置以产生更多的直接推进力，通常这会导致更省力的动作出现。
- The theory behind this method is that a continuous application of propulsive force is created, something that is not possible with front quadrant or catchup swimming. 这种划臂方法的理论是可以连续不断地产生推进力，而采用前交叉或者是调果味酱似的方法则是不太可能的事。
- The external force, or the pulling force, is an example and orientation of Chinese reformation while the internal force, or the propulsive force, is the motive and power. 外力是拉力，是中国改革的榜样与取向。内力是推力，是中国改革的动因与动力。
- The thesis primary interpreted the shipping propulsive force, shipping obstruction force, shipping manoeuvre and steady modeling especially, and interpreted the principle of PID control algorithm properly. 重点解释了船舶推进力、船舶阻力、船舶操纵和船舶初稳性建模方法,并适当表述了PID控制算法的原理。
- In simpler terms, it is kinesiologically incorrect to attempt to develop maximal propulsive forces with the body rolled beyond 45 degrees. 简单来说，试图以超过45度的身体滚动来获得最大化的推进力的尝试是错误的。
- The best streamlined shape possible but one which supports the most efficient production of propulsive forces is a more complete concept for contemplation positions in the water for speed swimming. 一个最佳的流线型可能是最好的但是如果能和竞技游泳中的预期位置及有效的产生推进力等要求相结合才更加完善。
- No propulsive forces can be created in a long, side, stretched position and consequently, if that position is held, a swimmer will slow down due to the presence of only resistive forces. 一个长的，伸展的身体形状不可能产生推进力，反而会由于保持这样的姿势使身体只能产生阻力而速度减慢。
- The SERN of a hypersonic vehicle was designed for improving the lift and propulsion force. 摘要为了提升高超声速飞行器单壁膨胀喷管的升力和推力，对其进行了优化设计。
- Preliminary analysis shows that the propulsion force is relative to serval factors, such as liquid viscousness, drive fin wet area and offset, etc. 分析表明,鱼形微机器人推进力与流体的粘性系数、摆翼面积和偏移角等因素有关。
