摘要
分析了盛装液体的容器在各种不同运动条件下液体内部的压力、质量力及其与自由液面间的关系。研究表明,不论容器的运动条件如何,质量力总是垂直于液体自由液面,质量力不但随加速度的增大而增大,还随斜面倾角的增大而增大。盛液容器在斜面上运动时,其中相对静止的液体中的压力不仅与液体深度有关,还与斜面倾角有关,当斜面倾角或加速度为0时,压力表达式的形式与静止容器液体内部压力的表达式完全相同,仅为液体深度的函数;只要加速度为0,不论斜面倾角如何,自由液面就是水平面。
The pressure, mass force and the relations between the direction of the mass force and the free surface of the liquid contained in a vessel under various motion conditions were analyzed . It is shown that the direction of the mass force is always vertical to free surface of the liquid without regard to the motion conditions;mass force increases not only with the acceleration of the vessel increasing, but also with the inclination of the plane increasing;when the vessel containing liquid moves on the plane, the pressure in the liquid is concerned with both the depth and the inclination. If the inclination is zero, the equation of the pressure is the same as that when the vessel is static, or the pressure is concerned .only with the depth;as long as the acceleration is zero, the free surface of the liquid is always horizontal plane regardless of the inclination.
