1) water surface flow rate and direction
水面流速流向
1.
The traditional measurement of water surface flow rate and direction,in which theodolite intersection was used and a great deal of human and equipment were involved,has a great deal of workload and is time consuming.
传统的水面流速流向测量采用经纬仪交会法,需要大量的人力和设备,工作量大且费时;DGPS技术施测水面流速流向虽然大大减缓了这一矛盾,但也有其局限性。
2) groundwater velocity and direction
地下水流速流向
3) current velocity and direction
流速流向
1.
Traditionally, surface current velocity and direction measurement mostly adopts intersection method with theodolite, which requires significant amount of manpower and instruments; what′s more, it takes both time and effort.
传统的水面流速流向测量多采用经纬仪交会法,此法需要大量的人力和设备,工作量大且费时。
4) vertical current profile
垂向流速剖面
1.
Numerical simulation of vertical current profiles;
深海垂向流速剖面数值模拟
5) Measuring surface flow direction and flow rate
表面流向及流速测量
6) flow velocity
水流流速
1.
Effect of ecological engineering of the streams entering lake on flow velocity;
入湖河道生态修复工程对水流流速的影响研究
2.
In turbulent flow,fluctuation of flow velocity must lend the fluctuation of flow resistance which is proporational to the square of flow velocity.
在整个水深范围内,水流流速样本系列服从正态布分。
