bed-load

基本解释

Saltations of solid grains in open channel flow are main form of bed-load transport.
水流中颗粒的跃移是推移质运动的主要形式。
It is very important for study of mechanics of bed-load transport and of bed-load transport rate.
这对于了解推移质运动机理及进行推移质输沙率研究有着重要的意义。
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.
胶州湾沙滩供沙的主要机制是通过风暴潮期间强烈的动力作用，使沙滩沉积物以悬移质、底移质形式向深水区扩散或搬运。

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

推移质
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.
用对数正态分布描述卵石推移质输沙率的随机特性 ,证明在 95 %的置信水平下是成立的。
