共轭水深 meaning in English

alternate depth
conjugate depths of the jump
conjugated depth

The water current flows over the top of the dentoid baffle to the hydraulic jump as additional momentum . while it is cooperated with a stilling basin , the flowing condition emerged in the basin may be improved greatly and the length and downstream water depth required by the basin can be decreased to a great extent . such an appliance may be also used to solve the problems of insufficiently dissipating water flow energy and aerating flow , which are often faced with those hydraulic engineering constraction as acted by high waterhead , great specific discharge and low froude number
本文通过齿墩顶部的扩散水舌所形成的附加射流，从上部射入水跃，即可改善消力池内的水流流态，又可降低第二共轭水深，减小水跃长度，增进水跃消能效果，同时还能解决大单宽、低佛劳德数条件下掺气和消能不足的问题，试验证实它是一种安全、经济的消能工。
