current constants

I was bold and strong, and familiar with the tide.

当年我既勇敢又身强力壮，对涨潮落潮的事也看惯了。

Is the tide coming in or going out?

现在是涨潮还是落潮?

The flood and ebb tides alternates with each other.

涨潮和落潮交替更迭。

Results show that (a) the flood tidal duration is shorter than the ebb tidal one;

结果表明 :潮流历时涨潮比落潮短 ;

the range and rotation during the flood is larger than during the ebb.

落潮历时一般大于涨潮历时，而落潮流速明显大于涨潮；

At the lower reaches of the South Branch, the velocity of the ebb current is larger than that of the flood current and the ebb tide duration is longer than that of the flood.

在南支下游,落潮流大于涨潮流,落潮历时大于涨潮历时;

(of the tide)start to come in or go out

（指潮水）开始涨或落

The tide ebbs and flows twice in 24 hours.

潮水每24 小时涨落两次。

the rhythm of the tides, seasons

潮汐的涨落、 四季的循环

tail up and down the stream

随着潮水涨落而起伏

Every tide have its ebb.

潮水有涨落，人生有盛衰。

(be)in a state of flux and reflux

处于潮涨潮落状态;[喻](人、事)荣枯, 盛衰

(be) in a state of flux and reflux

处于潮涨潮落状态; [喻](人、事)荣枯, 盛衰

and the average flow velocity of rising tide is generally bigger than that of ebb tide.

涨潮平均流速一般大于落潮平均流速。

To rise. Used of the tide.

涨潮涨起。用于描绘涨潮

during the spring-tide , in the south channel it in flood tide is greater than that in ebb tide while in the north channel it in ebb tide is greater than that in flood tide;

大潮时,南槽涨潮悬沙浓度大于落潮悬沙浓度,北槽落潮悬沙浓度大于涨潮悬沙浓度;

A line or an artificial indicator marking the high-water or low-water limit of the tides.

潮痕标记涨潮和落潮时潮水边缘的线或人为的标记

Roughness length during the flood phase is larger than that during the ebb phase, whilst shear velocity during the flood phase is smaller than that during the ebb phase.

涨潮阶段床面粗糙长度大于落潮阶段，涨潮阶段摩阻流速小于落潮阶段。
