Yet this epoch - making discovery causes another dilemma : it contradicts newtons law of gravity which implies that gravitational force is instantaneous , that is having infinite speed.
可是这一划时代的发现却带来另一项矛盾：它和牛顿重力学暗含的瞬时重力影响大相迳庭。

Although the resistance force increase of series nozzles makes the average energy of jet flow decreased but it lets the instantaneous energy modulated to impel more fluid resonances.
The gradient algorithm was adopted to calculate the required control force to suppress the rotor's instantaneous response coming from the parameter variance in the stiffness varying control of rotor.
