velocity n. 1.迅速;快速。 2.速度,速率。 3.周转率。 at a velocity of 100 miles per hour 用每小时一百英里的速度。 dart off with the velocity of a bird 像鸟一样迅速飞跑过去。 drag-free velocity无阻力飞速,真空飞速。 escape velocity(克服地球引力的)第二宇宙速度,逃逸速度。 final velocity (发射物的)终速。 initial [muzzle] velocity(发射物的)初速[腔口速度]。 uniform [variable] velocity匀[变]速。
Frequency distributions of properties, e.g. size and settling velocity are necessary to the description of sediments . 粒径和沉速的频率分布特性对于描述泥沙都是必需的。
Study on the fine sediment settling velocity formula with the parameter of ca2 concentration 含离子浓度参数的粘性泥沙沉速公式研究
The floe settling velocity of sediment particles is taken as the function of current velocity , salinity and suspended sediment concentration 泥沙颗粒絮凝沉降速度考虑了流速、盐度、含沙浓度的影响。
With the increasing initial orientation angle and length - width ratio , the drifting distance , the fluctuation of the orientation angle , lateral drifting velocity and rotation velocity all increase , while the final settling velocity decreases with the increasing length - width ratio 初始取向角和长宽比增大,则粒子的横向漂移以及取向角、侧向漂移速度和转动角速度的振荡幅度都增大;同时随着长宽比的增大,粒子的沉降速度相应减小。
This paper , as for the contradiction happened in design , construction , acceptance check when the quality of the project was needed and the building speed is different in every section of the road , the residual settlement a h is needed to be less than the standard value , launches the project - - - - - - the analysis on the settling velocity o f high earth fill sub - grade and the study of stability 本文主要是针对近几年来在设计、施工、竣工验收在工程质量评定中所出现的矛盾? ?一条公路少至几公里至几十公里,甚至上百公里,由于各个标段完工速度不一致,其剩余沉降值(即竣工验收时) h要求小于“评定标准” (即垂直变形3cm ) ;而进行的《高填方路基沉降速度分析与稳定性研究》课题研究。
