bed-load

基本解释

Saltations of solid grains in open channel flow are main form of bed-load transport.
水流中顆粒的躍移是推移質運動的主要形式。
It is very important for study of mechanics of bed-load transport and of bed-load transport rate.
這對於了解推移質運動機理及進行推移質輸沙率研究有著重要的意義。
The nearby beaches may supply sediment for the embayment during storm surges, by causing bed-load and suspended-load transport of the beach material towards deeper waters.
膠州灣沙灘供沙的主要機制是通過風暴潮期間強烈的動力作用，使沙灘沉積物以懸移質、底移質形式曏深水區擴散或搬運。

The engine is mounted on a test-bed and attached to a computer-controlled dynamometer, which is used to apply an adjustable load.

推移質
The stochastic characteristics of temporal pebble bed-load transport rate is described by a lognormal probability distribution. The Kolmogoroff test shows that 95% level of confidence can be obtained by this probability distribution function.
用對數正態分佈描述卵石推移質輸沙率的隨機特性 ,証明在 95 %的置信水平下是成立的。
