查询词典 drag force

The drag force adds flow resistance to the movement of an object in the opposite direction to its velocity, as in a fluid.

拖拽力是描述的一个与物体的运动速度方向相反的阻力，例如在液体中。

Because the condition of current drag force of group piles is more complex than that of single pile, it is difficult to solve the problem in theory.

The drag force depends on the density or thickness of the fluid; for example, moving through air is easier than moving through water.

拖拽力的值取决于液体的密度和粘稠度；例如在空气中移动一个物体要比在水中移动一个物体要容易的多。

The characteristics of the system were estimated by using correlative theory considering the effect of the drag force.

购买并加工制作了实验所需设备或器件(喷嘴、热源、压力泵和各种测量仪器等)，搭建了实验平台。

The drag force s are the major forces that make the object move in the horizontal direction.

抛筑在水流中的块体，在水流作用下一般受到水平拖曳力和垂直上举力的作用，其中水平拖曳力是促使物体运动的主要动力。

The results show that the stronger the particle-particle collisional dissipation and gas-solid drag force, the more heterogeneous the flow structure.

计算结果表明颗粒间非弹性碰撞和气固间曳力的增大均使气固两相流动的非均匀性增大。
