body force

基本解释

When considering body-force, free item will be arised in the equation of the boundary element method, causing boundary integration to be changed into nonlinear-integration.
边界元法在考虑体积力时要产生积分自由项，这将使边界积分成为非线性积分，从而引起实施时的困难。
In the investigation, the four channels were all heated at one end and cooled at the other, and the thermal driving of fluid is used to accomplish the heat transfer in a high body-force field.
本文利用数值模拟，通过改变流体的密度、黏性系数以及导热系数等热物性参数随温度的变化规律，讨论了不同物性参数对循环小通道内热驱动运动及其换热效果的影响。
All the numerical simulations and experiment studies in this thesis show that heat transfer can be enhanced using the liquid's thermally driven in a micro-circular enclosure in high body-force field.
通过本文的试验研究和数值模拟，说明可以通过在高彻体力场中构造出一个封闭循环微小通道，利用通道内流体的热驱动达到强化冷却的目的；

We can be precise about how much bigger by saying, "If the acceleration of a body to a given force is ten times that of a one kilogram mass, then this mass is one-tenth of one kilogram."
我们能精确地知道质量能大多少,只需要说,"如果物体在给定力作用下的加速度,是一个 1 千克物体的加速度的 10 倍,那这个物体的质量就是 1 千克的十分之一"
