查询词典 cyclone

The change in the tropical cyclone intensity as it passes the area near to Shanghai is remarkable. In general, the minimum surface level pressure of tropical cyclone center near to Shanghai is greater than 920 hPa.

上海及其近海区域台风强度随纬度增加而减弱的变化特徵明显，在东海北部，近50 a内尚未出现过中心气压低920 hPa的台风。

The real tangential velocity fluctuation indicated that there existed an instability of swirling flow in the cyclone.This instability resulted in the rotation center of the swirling flow deviating from the geometric center of the cyclone,which produced the quasi-periodic oscillation of swirling flow and gave the real tangential velocity fluctuation.

瞬时切向速度的变化反映了旋风分离器内旋转流的不稳定性，这种不稳定性导致了旋风分离器内旋转流的旋转中心与几何中心不重合，旋转中心围绕着几何中心摆动，由此造成了瞬时切向速度随时间的类周期的波动变化。

Design of the structural of the cyclone collector with double outlet for dust is based on the traditional cyclone collector.

双出风口分离器的结构设计主要是在单出风口分离器的基础上改进而来。

The structure, flow field distribution and the dust separating procedures of inner speeding vortex cyclone collector are very different from that of traditional cyclone dust collectors.

混流区和中心旋流区是内旋流加速旋风集尘器的主要特征之一。

The structures and the critical dimensions of a normal cyclone separator are improved, and a new type of cyclone PV-E is developed.

Under different structural parameters of exit tube,including the inner diameter and the structure shape,the separation efficiency and pressure drop of the guide vane cyclone tube were measured by comparative experiments and the flow field in the guide vane cyclone tube was measured by an intelligent five-hole pilot tube.

通过对比实验测定了不同排气结构下导叶式旋风管的分离效率及压降，同时用智能型五孔球探针测试仪测定了不同排气结构的旋风管内流场分布，结合性能实验与流场测量的结果，研究了排气芯管内径及其结构型式对分离性能的影响，为旋风管结构优化和开发及其分离机理的研究提供了一定的实验基础。

It suggests that the horizontal momentum of the meso-cyclone was brought down to the surface by heavy rain. At the right edge of meso-cyclone the momentum and RIF have the same direction, the two airflows overlay together and make the wind increase, so damage wind occurred.

分析认为，弓状回波后部存在较强后部下沉入流，由于强降水的拖曳作用，将中层中气旋的水平动量带到地面，中气旋右侧动量的方向与弓状回波后部的强下沉入流方向一致，两者叠加，使地面风速加大，造成灾害性大风。

The wind convergence, mesoscale cyclone and vertical wind shear at lower levels may produce heavy rainfall. The mesoscale cyclone and vertical wind shear at middle and upper levels may produce strong downburst or hails.

低层水平风的辐合、中气旋、垂直风向切变等可以产生强降水，中高层的中气旋、垂直风切变可以产生下击暴流、冰雹等强对流天气。
