- 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 ball glanced off the goal post into the net. 球撞到球门柱上斜飞入网。
- The net weight of this jar of coffee is 180 grams. 这瓶咖啡净重180克。
- 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。
- If I lose my job, I've got no safety net. 我丢掉这份工作就无计可施了。
- 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。
