ebb-tide

59 Every tide hath its ebb.

59潮涨必有潮落时.

The age of printing turned into a period of ebb-tide when the historical twilight has been cast into the culture field and leave behind the last shadow in the twenty centuries.

当二十世纪末的历史余晖在古老的文化原野投下最后一抹背影时，印刷时代的文学宿命般的步入了落潮期。

The method was applied to the Nanhui nearshore waters. Calculating results indicate that the average settling velocity during flood tide stage is 3.46mm/s and 3.00mm/s during ebb stage;

用这一方法近似计算得到南汇近岸水域的悬沙沉速：涨潮阶段平均为346mms，落潮阶段平均为300mms；

M.drew on the ground the figures of the sun, moon, and earth and tried to explain gravitation, ebb-tide, flood-tide, new moon, full moon, eclipse, and so forth.

在地上画了太阳、月亮与地球的轮廓，设法解释引力作用、退潮、涨潮、新月、满月、月蚀等诸如此类的关系。

the ebb and flow of the tide

海潮的涨落

Ebb tide is tranquil, not like tide, when turbulent waves send spray spitting in every direction.

落潮是平静的, 不象涨朝那样波涛汹涌,浪花飞溅.

For determination of sediment transport rates due to flood and ebb tide currents, the Gadd equation is modified through a definition of the frequency distribution function of current speeds within the harbour entrance.

此外，还用改进的Gadd公式确定口门涨、落潮流输沙率，计算中引入汊道口门流速频率分布函数的定义。

Ebb tide: the receding or outgoing tide; the period between high water and the succeeding low water.

落潮：退去或退落的潮水；高水位相继的低水位时期。

Water level upstream is higher than that downstream during the ebb tide, and water level descent of ebb tide is one order bigger than that of flood tide.

落潮期间上游水位均大于下游水位，水面坡降落潮比涨潮大一个数量级；涨价的东西也会落价。现在是涨潮还是落潮？

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.
