1·Both charge inversion and flow reversal can't be accounted for in continuum theory.

连续性理论无法解释电荷的倒置与反转电渗流这两种现象。

2·The results show that the emission level of the cyclic flow reversal combustion is lower than that of one-way flow combustion.

结果表明，相对于单向流动，往复流动有更好的燃烧排放效果。

3·Slamming of check valves is the result of failure of the valve disc to reach its closed position before the fluid flow reversal.

止回阀的撞击现象，是由于在流体倒流之前，阀门的阀瓣没有到达关闭位置造成的。

4·The DSV? is an in-line spring-assisted check valve designed to prevent flow reversal in industries with strict cleanliness codes.

同轴、管内弹簧止回阀，工业上要求严格的清理时可用来防止水倒流。

5·Swing-type check off er the least pressure drop and offer simple automatic closure; when fluid flow stops gravity and flow reversal closes valve.

旋启式止回阀压降最小，能够完全自动关闭，即在介质流动停止、重力和介质倒流的状态下自动关闭阀门。

6·A new computational scheme was developed to solve a three-dimensional model of a periodic flow reversal reactor by ADI alternating direction implicit method.

文中针对圆管式径向对称流向变换反应器三维模型，利用交替方向隐式方法(adi)建立新的求解格式。

7·The existence and uniform boundedness of the global solutions of the model for sulphur dioxide oxidation in a tubular reactor with periodic flow reversal are proved by the invariant domain method.

利用不变区域方法，证明了二氧化硫催化氧化管式反应器流向变换强制操作模型整体解的存在性和一致有界性。

8·Swing check valves are used to prevent reversal of flow in horizontal or vertical pipe lines.

旋启式止回阀用于防止水平管路或垂直管路的流体倒流。

9·Es is caused by long-standing left-to-right shunt lesions, which induce pulmonary vascular changes, resulting in reversal of the shunt flow.

ES是由长期左向右分流引起，该左向右分流诱导了肺血管改变，导致分流方向逆转即右向左分流。

10·Swing Check valves prevent reversal of flow through pipe lines.

旋启式止回阀可以防止管路中的流体倒流。
