查询词典 condensation

Study of the causes of MCS intensification and rainstorm shows that( 1) just before the heavy rains occur, there are high temperature, considerably wetness and unsteady convective stratification in the air over the rainstorm-hit area, in addition to significant increase in convectively efficient potential energy, condensation height and decrease in the height of free convection – all these favor the happening of the heavy rain,(2) the mergence of meso-βcloud clusters leads to the MCS such fast growth as to produce rainstorm,( 3) the two lines of cumuli in the north and west correspond, separately, to two convergences on the surface wind field, with stronger convergence at their meeting point responsible for such intense development of meso-βcloud cluster as to bring about torrential rains.

分析MCS加强和产生暴雨的原因表明，首先，暴雨发生前夕暴雨区域具有高温、高湿和对流性不稳定层结，并存在明显的对流有效位能增加、抬升凝结高度及自由对流高度降低的现象，有利于暴雨发生。第二，β中尺度云团之间的合并，使MCS迅速增长，产生暴雨。第三，北、西两条积云线分别与地面风场中的两条辐合线相对应，在它们交汇处的较强辐合导致β中尺度云团强烈发展产生暴雨。

The type of cell death caused by ricin was related to the ricin concentration and time of incubation with HeLa cells. The typical apoptosis was induced by ricin 0.05μmol〓. The apoptotic cells mainly showed cell shrinkage, cytoplasmic membrane blebbing, the chromatin condensation and fragmentation, crescentic nuclear and membrane bound apoptotic bodies formation.
