常見例句雙語例句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(yàn),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。 返回 bed silt
