This issue discussed the mechanism of CGA-column flotation, and discussed the separation course of cyclone-static microbubble column, it concluded that the principle of flotation colurmn、 the principle and course of selfinduction、 pipe flotation and mineralization of microfoams、 the liquid state of column separation stage、 the principle of cyclone stage dynamics separation and strengthen the mechanism of cycle recovery of column.

本文对CGA-柱浮选的机理进行了探讨，论述了旋流静态微泡浮选柱的分离过程，包括浮选柱工作原理、自吸式充气原理与过程、管浮选与气泡的矿化、柱分离段的流体状态、旋流段力场分离原理和浮选柱的强化回收机制。

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.

本文说明了天气图上的流场可以分解为旋转场和变形场：地转无摩擦的气旋、反气旋的涡旋型式是围绕中心点的闭合环流；考虑摩擦的气旋、反气旋的流型是围绕焦点的螺旋型式；鞍型场有4个涡旋中心点（2个气旋和2个反气旋）与1个鞍点；阻塞高压和切断低压由1个涡旋中心点与1个鞍点组成。

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 .

结果表明：受副热带高压后部深厚的暖湿气流及西风带高空槽、切变线及气旋倒槽等动力系统共同影响，庄河地区出现了大暴雨天气，但没有出现强雷暴，此过程主要影响系统是地面气旋倒槽；700hPa、850hPa低涡、切变线使中低层辐合加强，形成了较强的动力抬升和水汽辐合；庄河地区处于强而宽的假相当位温锋区中，位势不稳定的建立是造成此次强降水的必要条件。

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.
