stream velocity meaning in Chinese
河流流速
水流速度
Examples
- The velocity in the intake is not equal to the stream velocity .
进口的流速不等于河水流速。 - Effect of vareriana officinalis var . latifolia miq on arteria basilaris caliber and blood stream velocity of rabbit with subarachnoid hemorrhage
宽叶缬草对兔蛛网膜下腔出血后基底动脉管径和血流速度的影响 - In addition , the microcosmic stream , especially suspended load ( mainly suspended soils and sands ) reflected on the characteristic of transported sands " streams , and always silt up and form shoal in the place where the stream velocity is lower and river steam return easy
河道的微观水流，特别是悬浮物(主要是悬浮泥沙)反映输沙水流淤积特性，总是在流速缓慢、易回流的地方淤积、形成新生沙洲，为正在发生及将来发生的河道淤积和演变打下基础。 - The geomorphological instantaneous unit hydrograph ( giuh ) is viewed as the frequency distribution of the times of arrival of individual water deoplets at the catchment outlet . the travel path , for a typical hillslope cell . consists of a hillslope fraction , corresponding to overland flow and a stream fraction , corresponding to concentrated channeled flow . to obtain the time of travel , velocities must be defined . hillslope and stream velocities vary with location and must be strongly correlated with slope , and therefore a spatial distribution of velocities and hence of travel times could be obtained . the present methods of giuh neglect any time delays associated with overland flow pathways
地貌单位线被看作是流域上各水质点在弱相互作用下，到达流域出口汇流时间的频率分布。对于一个典型的山坡型网格单元，汇流路径由两部分组成，即坡地部分和河道部分，为了得到汇流时间，必须首先确定汇流速度。坡地和河道的汇流速度随着区域位置而变，并且必然与坡度有关，因此，可首先计算流速的空间分布，进而得到汇流时间的空间分布。 - A new method is presented . the travel time , including the time delays associated with overland folw pathways , is obtained . it is expected that the hillslope velocity and the stream velocity are different , and different equation is used . in the method , the fact that velocity increases going downstream in river systems is taken into account . after the travel time of each cell being calculated , the frequency distribution of the times of arrival of individual water droplets at the catchment outlet - giuh , is obtained
提出了一种汇流时间计算方法，汇流时间中包括坡地漫流时间和河道汇流时间。方法中坡地单元的汇流速度与河道单元的汇流速度采用不同的计算公式，同时考虑流速沿河道向下游的变化。流域中每一个网格单元的汇流时间得到后，将其看作随机变量，进行统计分析后，得到汇流时间的频率分布? giuh 。
