The downward flow of a paint or powder that is applied too heavy or onto a hot surface.
油漆或粉末喷涂太厚或喷在预热的表面，从而使涂膜往下往下流动。
This creates downward air currents. These downdrafts hit the surface of the planet, flow outward, and collide with each other, forming updrafts.
气流向下落在地球表面，向外流动，相互碰撞，如此一来就形成上升气流。
In a typical software system, function calls flow downward from higher-level components to lower-level ones; whereas events percolate up in the opposite direction. Figure 1 illustrates this pattern.
在典型的软件系统中，函数的调用流是从较高级部分到低级部分进行的；而事件是以相反的方向过滤的，如Figure1所示。
Air is forced up from the buoy counterweight tube during downward motion causing the balls to seal the air ports in the valve, thus forcing the air to flow into the whistle.
空气在向下运动过程中受到浮标向上的推力，使阀球将阀门里的气舱密封住，这样迫使气流进入雾笛。
Tumbling flow is appeared in this fishway which produces wave surge and continues to flow downward and may causes serious damage due to its behaviour of periodic tumbling action.
在这种鱼道中出现的滚动流将产生波涌，并继续向下传播，而且它的周期性滚动可能会严重危害鱼道。
The void fraction in downward gas oil two phase flow in vertical tube is measured with the combined method of horizontal downward vertical tube for the two flow regimes(bubbly and slug flow).
采用水平—下降管组合法测量了垂直下降管内油气两相流动在泡状和弹状流下截面含气率的值。
Lock the fold hydraulic lever for continuous downward oil flow. If wings are running too high, increase pressure setting to level machine.
对于连续的向下供油应当锁定折叠的液压位置，如果侧翼在工作时太高，应当增加压力使机器水平。
The reactants are initially pumped vertically downward by the viscose drag force of the high speed rotating disk, and then are deflected to form a flow region that is parallel to the wafer carrier.
反应物在初始阶段因高速旋转盘的牵引力被竖直向下地泵入，然后偏斜形成一个与衬底片托盘平行的流动区域。
In horizontal position welding, the gravity makes molten metal flow downward and sometimes causes weld defects such as undercut and overlap.
横向焊接时由于熔化金属重力的作用，会引起熔池金属下淌，从而产生咬边以及焊瘤等焊接缺陷。
The volume quality of top soil is increased and the soil porosity is reduced owing to compaction, so water flow downward difficultly and the amount of water vertical infiltration is reduced.
由于压实，增加了表层土壤的体积质量，降低了土壤孔隙度，水不易向下运动。
The process includes the waste purification from oil emulsion in Tilted-Plate Separator and the suspension separation in the downward-flow sand-gravel filter.
处理方法包括使用倾斜盘式分离器分离油乳化剂，使用下流式砂砾过滤器分离悬浮颗粒物。
The variance of mean flow could propagate downward gradually, for some time it reached to surface and effected atmospheric circulation and weather progress.
平均流的变化会逐渐下传并可能在一段时间之后到达地面，影响地面大气环流和天气过程。
