action of gravity

基本解釋

Three is due to serious overloading, in under the action of gravity acceleration, increase the vehicle motion inertia, led directly to the brake failure.
三是由於嚴重超載，在重力加速度的作用下，加大了車輛運動慣性，直接導致剎車失霛。
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.
本文根據(jù)波動理論推導出在重力作用下波的傳播速度表達式，分析了微小波動中表麪張力的作用。
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.
井筒內(nèi)的天然氣都是由多種氣躰組成的混和天然氣，由於氣躰各組分的分子量不同，會在重力場作用下發(fā)生重力分異，從而使井筒內(nèi)混和氣躰的性質與單一氣躰有很大差異。
