Therefore, the moist potential vorticity analysis associated with the mesoscale convective system was researched in the paper, so as to reveal the moist potential characteristics of mesoscale convective system in typhoon circulation. The results showed that, during the generation stage, convective instability characterized by MPV1 was a favorable condition for forming MCS, while the vorticity which was caused by the slantwise isentropic surface and the vertical shear of the horizontal wind characterized by MPV2 was an inspiring mechanism. The specific process was that, the atmosphere exhibited the feature of strong convective instability at the low level of convection areas and the southeast areas, which included plenty of erratic energy. The slantwise ascended the stream transfer the erratic energy to northwest, where the stratification stability was small. As decreased, the cyclonic vorticity increased. On the other hand, the vorticity caused by the slantwise isentropic surface and the vertical shear of the horizontal wind inspired the release of convective instability and as a result that the MCS formed. During the development stage, the cyclonic vorticity increased quickly with the persistent decreasing of . Meanwhile, the inclination of isentropic linewas bigger than the absolute momentum line at middle level, which exhibited the feature of conditional symmetric instability , then the conditional symmetric instability was forced to release by the vorticity resulted from the slantwise isentropic surface and the vertical shear of horizontal wind, and the MCS developed.

结果表明，在对流形成阶段，MPV1即对流不稳定为MCS的形成提供背景不稳定条件，由MPV2即湿等熵面的倾斜和水平风的垂直切变而引起的涡旋发展作为强迫机制：MCS形成的区域及东南区域中低层是强对流不稳定层，蕴含丰富的不稳定能量，倾斜上升运动把对流不稳定区具有强不稳定能量的暖湿空气向西北中层的中性层结区输送，由于的减小，气旋性涡度增强，有利于形成对流，另一方面，由于湿等熵面倾斜和低空急流加强而引起的涡旋发展作为一种强迫机制激发对流不稳定能量得到释放，从而形成对流；在对流系统地发展阶段，由于低层的对流不稳定性进一步减弱，进一步减小，气旋性涡度进一步增强，有利于MCS的增强，中层等θe 线的倾斜度比绝对动量M 等值线的倾斜度大，对应有条件对称不稳定区域，满足条件对称不稳定条件，在湿等熵面倾斜和台风低空急流作用下引起的涡旋发展强迫对称不稳定能量释放，从而使得对流得以维持和加强。

In summer, because the vertical incident solar rays regionmoves by the equator to the north, causes of southeast trade crossingthe line the southern hemisphere to change the southwest monsoon toinvade Northern Hemisphere, meets one another with the originalNorthern Hemisphere's Northeast Tradewind, compels crowds this airrise, the increase convection current, again because the southwestmonsoon and the Northeast Tradewind direction is different, meets oneanother often creates the undulation and the whirlpool.

在夏季，因为太阳直射区域由赤道向北移，致使南半球之东南信风越过赤道转向成西南季风侵入北半球，和原来北半球的东北信风相遇，更迫挤此空气上升，增加对流作用，再因西南季风和东北信风方向不同，相遇时常造成波动和旋涡。

Rotating Air Preheater was produced in China in 1980's via the technology introduced from the America CE Corp.

回转式空气预热器是我国八十年代由美国CE公司引进技术制造的，是电站锅炉的重要辅机之一，它起着利用热能的热交换作用。

The pump body consists of suction chamber, liquid storage chamber, turbination chamber, liquid return port, gas-liquid separation chamber, etc. After the pump starts normally, the impeller will suck the liquid in the suction chamber and the air in the inlet line so that the both can mix fully in the impeller. Due to the centrifugal force, the liquid along with the gas flows towards the outer edge of the turbination chamber and then a belt of white foam with a certain thickness and a liquid ring with high-speed rotation come into being on the outer edge of the impeller.
