Tornado is a small-scale system which as the maximal horizontal and vertical velocities in the atmosphere. 龙卷风是大气中风速和垂直速度(VV)极大的小尺度系统。
The simulation model of jump control was established, and the vertical velocities were found. 文中建立了抬刀控制过程的仿真模型,也能发现其间隙流场有竖直方向分速度的存在。
The results showed that the distribution of particle diameter has great effects on particle vertical velocities, and that the mixing of different particle diameter is favorable for particles flow. 结果发现:颗粒的粒径分布对颗粒垂直速度(VV)分布有很大影响,不同粒径的混合有利于颗粒的流动;
Then the objective functions are established for joint inversion of Thomsen's anisotropic parameters with vertical velocities and NMO ellipses of three pure modes in a single monoclinic layer. 根据各向异性介质中方位NMO速度与Thomsen参数之间的关系,建立了利用三种波的多方位NMO速度及垂直传播速度反演单层单斜各向异性介质Thomsen各向异性参数的目标函数。
A group of 6 stable stations in the east part of China with the same variation pattern and small annual vertical displacement velocities are used in datum definition for vertical displacement time series. 取中国东部一组垂直位移变化形态基本一致、年速率较小的6个基准站作为垂直位移时间序列的基准。
