water crest

The skiff rises to the crest of the swell, crosses it, rides down the long hill of water behind, advances up the next slope. The ship knifed through the heavy seas.

小船冲上了浪峰，越过去，顺着后面的水坡滑了下去，然后再爬上下一个坡。船在波浪汹涌的海中破浪前进。

When the easy water cold crest wears a murmur to leave, the that extremely bossy Pu much more western young master has already become an idiocy of standard, will hurtle a person silly smile.

当易水寒顶着咕噜离开，那个作威作福的普西多少爷已经成为一个标准的白痴，只会冲着人傻笑。

If a gate is to be installed on the crest, orifice flow can be trans-formed into broad-crested weir flow at any water heads, provided that the suggested limitations are taken into consideration in hydraulic design.

若堰顶设有闸门，如果在水力设计中考虑了上述极限控制条件，则在任意堰顶水头情况下，都可以完成从孔流到宽顶堰溢流的过渡。

The reason for the depths at the water drop and overflow spillway crest are smaller than the critical depth computed with the current formula is explained.

同时还对流线的凹向、流线曲率半径及水面坡度对临界水深的影响进行了分析，论证了趺水处和曲线型实用堰堰顶的水深均小于按现有公式计算的临界水深的原因。
