回流

Just as I had set my Mast and Sail, and the Boat began to stretch away, I saw even by the Clearness of the Water, some Alteration of the Current was near; for where the Current was so strong, the Water was foul; but perceiving the Water clear, I found the Current abate, and presently I found to the East, at about half a Mile, a Breach of the Sea upon some Rocks; these Rocks I found caus'd the Current to part again, and as the main Stress of it ran away more Southerly, leaving the Rocks to the North-East; so the other return'd by the Repulse of the Rocks, and made a strong Eddy, which run back again to the North-West, with a very sharp Stream.

我刚竖起桅杆张好帜，船就开始向前行驶了。我发现四周水色较清，知道那股急流在附近改变了方向。因为，水急水则浊，水缓水则清，我知道那股急流在这儿已成了强弩之末了。不久我果然发现，在半海里以外，海水打在一些礁石上，浪花四溅。那些礁石把这股急流分成两股，主要的一股继续流向南方，另一股被礁石挡回，形成一股强烈的回流，向西北流回来，水流湍急。

This is because the jet particle velocity of the swirling water jet is three-dimensional, and its rock-breaking manner mainly has a slopping impact. Thus, the interference from returning fluid is less. All these aspects make it easy to draw and shear the rock surface.

计算结果与试验一致，表明旋转射流具有较强的破岩能力，其原因是旋转射流的质点具有三维速度，破岩时以倾斜冲击为主，易于在岩石表面形成拉伸和剪切破坏，回流的干扰较少。

A reflux condenser is attached, and the mixture is boiled continuously for at least two and one-half hours.

回流冷凝器是重视和混合煮沸的不断至少有两个和一个半小时。

放热反应发生的同时有水生成；用一个dean-stark trap接在回流冷凝管上用于收集反应中生成的水。

Apparatus— Use a 500-mL glass flask A connected by means of a trap B to a reflux condenser C by ground glass joints.

装置---使用一个与500ml的玻璃烧瓶A，与水分测定管B连接，使用磨口玻璃接头与回流冷凝器C连接

To protect the potable water supply from backflow from a non-potable source due to a drop in supply.

Function：防止由于高度降低而受到非饮用水源回流到饮用水供应系统中。

This series can be used to prevent the reverse flow of fire protection substances, i.e., glycerin wetting agents, foam agents, stagnant water, auxiliary supplies and water of non-potable quality from being pumped or siphoned into the potable water supply.

这个系列可以用于防止消防物质的回流，也就是防止甘油润湿剂，发泡剂，停滞水，辅助供应水和非饮用品质的水由于泵吸或虹吸进入饮用水供应系统中。

It is mandatory to prevent the reverse flow of fire protection system substances, i.e., glycerin wetting agents, stagnant water and water of non-potable quality from being pumped or siphoned into the potable water supply.

这种应用强调必须防止下列消防系统物质，如甘油，润湿剂，积滞水和非饮用级别的水由于泵吸或虹吸作用回流到饮用水供应系统中。

This sets up a trump winner for West, but he is backwash-squeezed at the same time.
