slack water
解釋
緩流-
After analyzing, the author got the basic character of tidal flat hydrodynamic : the time of flooding on bare flat and ebbing is basically the same and the time of flooding on pioneer zone of salt marsh is a little short ; the process curve of current speed on bare flat did not appear peak value on the beginning of flooding and at the end of ebbing but presented double peak, that is, it presented double peak in winter and spring and ebbing peak value disappeared in summer and autumn, salt marsh presented single peak character in a year and the process curve in tidal creek presented double peak ; all current direction on every spot presented gyration current and the current speed changed rapidly during the high water level without obvious slack water period
分析得到了潮灘水動力基本特徵：光灘水位漲潮和落潮時間基本相等，而鹽沼前緣帶水位漲潮時間略短；光灘流速過程線在漲潮初和落潮末出現峰值，呈現「雙峰型」特徵，鹽沼前緣帶則冬、春季節呈現「雙峰型」 ，夏、秋季節落潮峰值消失，鹽沼帶四季呈現單峰特徵，潮溝內過程線為「雙峰型」 ；各測點流向均呈現回轉流特徵，在高水位時流向迅速改變，不存在明顯的憩流。 -
From just the entrance, in the southern part of the bay, up to a second slack water area, about midway up the bay, tidal currents are ebbing
在海灣的南部，從緊靠入口處內側直到第二平潮區，其間距離大約是到海灣的一半，潮流正在回落。 -
