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。
The motion of individual particles is obtained by solving Newtons second law of motion and gas flow by the Navier Stokes equation based on the concept of local average.
颗粒的运动满足牛顿第二定律，流体相的运动规律由局部平均的纳维斯托克斯方程求解，两相间的耦合由牛顿第三定律决定。
