成熟分裂

The secondary oocyte now divides again into two new cells of unequal size: a relatively large ootid (mature egg cell) and a minute second polar body.

此时，次级母细胞又分裂两个大小不对等新细胞：一个相对很大子（细胞）和一个微小次级极体。

With the numerical simulated data of the storm, the structure and evolution of the helicity, superhelicity and their dynamical influences on the development of the storm are investigated.

有对流单体在地维持，表现出较强稳定性，而分裂出新单体在移动过程中，逐渐向位相发展，并且又分裂出新单体。
