河床流速
velocity───n.【物】速度
velocity profile───速度剖面(图),速度分布图,速度变化图
muzzle velocity───初速;出口速度;初速度(弹出膛时的速度)
constant velocity───常速度,等速度; 恒速;匀速;等速度;恒速度
angular velocity───[力]角速度
bed───vi.上床;分层;n.床;基础;河底,海底;vt.使睡觉;安置,嵌入;栽种
cratering velocity───弹坑速度
velocity magnitude───速度大小
terminal velocity───[力]终极速度;自由沉降速度;终速,自由沉降速度
preconditioned fastest descent means in inversion achieves simultaneous in - versions of overlying-bed velocity and refractor depth.───反演过程中利用具先决的最速下降法,可解决覆盖层速度和折射界面深度同时反演问题。
effects of fluidization number, injection velocity, particle mean diameter and static bed height on jet fluctuation are discussed.───研究了流化数、射流初始速度、颗粒平均粒径及静态床层高度对射流脉动特性的影响。
It is assumed that there is an "effective bed velocity" on the bottom which determines the erosion and deposition of the bed.───说明底部有一个“作用流速”,才产生底床的冲刷与淤积。
