So a kind of two-grade dust catcher system with higher efficiency, convenience and mechatronic is studied. The designed dimension of the first- grade cyclone separator is optimized by using MATLAB optimization toolbox. New designed cyclone separator has lower resistance loss, higher efficiency, compact structure and less volume; The mathematical model of hydrometry is b...

本文對CGA-柱浮選的機理進行了探討特黄特色A级无码毛片视频，論述了旋流靜態(tài)微泡浮選柱的分離過程欧美在线精品一区二区三区，包括浮選柱工作原理、自吸式充氣原理與過程日韩无码导航视频、管浮選與氣泡的礦化、柱分離段的流體狀態(tài)、旋流段力場分離原理和浮選柱的強化回收機制悠悠资源av男人免费站。

It is shown from this thesis that flow fields on synoptic maps can be decomposed into rotation and deformation fields. Geostrophic non-frictional cyclone and anticyclone vortex patterns are closed circulations around the center point, streamlines of frictional cyclone and anticyclone patterns have spiral forms around the focus point. Saddle fields have four vortex centers (two cyclones and two anticyclones) and a saddle point. Blocking high pressure and cut-off low pressure patterns consist of a vortex center and a saddle point.

本文說明了天氣圖上的流場可以分解為旋轉(zhuǎn)場和變形場：地轉(zhuǎn)無摩擦的氣旋欧美xxxx18、反氣旋的渦旋型式是圍繞中心點的閉合環(huán)流；考慮摩擦的氣旋性交3xxxxx在线观看、反氣旋的流型是圍繞焦點的螺旋型式日本黄在线；鞍型場有4個渦旋中心點（2個氣旋和2個反氣旋）與1個鞍點；阻塞高壓和切斷低壓由1個渦旋中心點與1個鞍點組成一级特黄AAAAA片。

The results indicated that the effect of deep warm-wet air coming along the behind subtropical high , moving eastward deepening upper trough , shear line and cyclone trough was caused in Zhuanghe , but no strong thunderstorm . The main impact of system is surface cyclone trough ; Low vortex , shear line in 700hPa , 850hPa strengthen the lower convergence , forming a strong momentum of increase and pieces of water vapor ; strong and wide potential pseudo-equivalent temperature frontal zone lied in Zhuanghe area , the establishment of potential instability are indispensable conditions for producing heavy rain .

On the basis of this, the role of condensational latent heat release is studied emphatically and a conceptual model of mutual positive feedback mechanism between the growing of meso-α-scale cyclone on MeiYu front and its accompanying intensifying precipitation due to stable condensational heating is posed, i. e. condensational heating generates negative allobar, divergent wind kinetic energy promotes meso-α-scale cyclone growing, and simultaneously, updraft motion is also reinforced, precipitation continues intensifying.

So the two methods have been chosen to detect and estimate the center of a tropical cyclone over China offshore.They are the Geometric Axisymmetric Center Positioning Method and the Velocity Distance Azimuth Display Positioning Method,respectively.The former decides the position of a tropical cyclone center using directly the Doppler radar radial velocity field,the latter does the position using the productV_(r×D of the Doppler radar radial velocity valueV_(r and the distance from observation site to radar center.
