bed silt

基本解釋

This low-lying bed of silt in Chad, across which powerful jets of wind are wont to blow, constitutes less than 1% of the Sahara's area but is reckoned the world's dustiest place.
博德里洼地坐落于乍得，是一片強(qiáng)風(fēng)盛行的低洼淤泥地，雖然它只占沙哈拉地區(qū)1%的土地，但是卻被認(rèn)為是世界上多塵的地區(qū)。
Studying the sediment vertical distribution affected by wave and current is the important base to explore the transport behave of sediment on the silt sea bed under the same conditions.
研究波浪和潮流作用下水體含沙量的垂線分布，是解析粉沙質(zhì)海岸灘面泥沙在波浪和潮流作用下泥沙運(yùn)移形態(tài)的重要基礎(chǔ)。
And in the flume experiments on a silt bed in lab, it is found that some low-strength area vibrates with wave shearing action, which leads to a moisture content depression and a density increase.
通過波浪對粉土底床作用的水槽試驗，發(fā)現(xiàn)強(qiáng)度軟弱區(qū)的土體在波浪剪切作用下發(fā)生振蕩運(yùn)動，振蕩運(yùn)動后的土體含水量降低，密度增加。
