In a same cloud band, the variation of temperature is small meanwhile the temperature is lower.The convective bubbles were observed in the warm clouds under the middle of the cumulostratus on 21,June 1992. The bubbles clearly show that they are one kind of mesoscale organization. It suggests that the synoptic system is situable to produce convective bubbles. Its contrastly analysed that the particle concentration and the liquid water content are higher.the particle spectra is similar,the particles captured by 2D-C probe are bigger in the bubbles.

1991年6月21日个例观测到对流泡位于层积云下部暖云中的部分，泡状结构明显，呈现出中尺度组织特征，天气系统的配置有利于垂直上升运动的发展：通过对比分析，发现对流泡内具有云滴浓度高、液态水含量较高、云谱型相似以及2D-C粒子尺度大等特点：本次个例观测到的对流泡内云滴谱表现为单峰型。

Cage shaped rotor includes following parts: columnar rotor core made from soft magnetic material, multiple bar conductors made from copper inserted into rotor core along up and down direction, short circuit rings made from copper installed on upper and lower ends of rotor core in order to realize electrical connection among each bar conductor. Preparation method includes steps: in step for preparing short circuit ring assemblies, bar conductors are installed between short circuit rings in upper part and lower part to keep electrical connection between short circuit rings in upper part and lower part; in step for forming columnar rotor core, pressurization molding soft magnetic material is carried out when short circuit rings module is in die so as to form rotor core, where bar conductors are inside and short circuit rings are in upper and lower ends.

一种电动机的笼子状的转子及其制造方法，电动机的笼子状的转子包括转子铁芯，用软质磁性材料制成，呈圆筒状；多个导体棒沿上下方向插在转子铁芯的外圈，用铜制成；短路环为能够与各导体棒实现电连接，分别安装在转子铁芯的上、下端，并用铜制成；其制造方法，即制作短路环组件的阶段，在这个阶段中在用铜制成的上部短路环与下部短路环之间安装铜质的导体棒，从而形成短路环组件，这些导体棒相距一定间隔，与上、下短路环保持电连接；形成圆筒形转子铁芯的阶段，在这个阶段中把短路环组件放在模具内，并用软质磁性材料进行加压成型加工，从而形成导体棒位于其内部、短路环位于其上、下两端的转子铁芯。
