action of gravity

基本解释

Three is due to serious overloading, in under the action of gravity acceleration, increase the vehicle motion inertia, led directly to the brake failure.
三是由于严重超载，在重力加速度的作用下，加大了车辆运动惯性，直接导致刹车失灵。
Based on the mechanics of wave, the expression of water wave propagation velocity under the action of gravity is deduced and the effect of surface tension on small wave is analyzed.
本文根据波动理论推导出在重力作用下波的传播速度表达式，分析了微小波动中表面张力的作用。
Natural gas in wellbore is a mixed gas consisting of various gas. Due to molecular weight of all kinds of gas is different, they will occur gravity segregation under the action of gravity field.
井筒内的天然气都是由多种气体组成的混和天然气，由于气体各组分的分子量不同，会在重力场作用下发生重力分异，从而使井筒内混和气体的性质与单一气体有很大差异。
