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，母细胞又分裂成两个大小不对等的新细胞：一个对很大的子（成细胞）和一个微小的极体。

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成的结构，表现出较强的稳定性，而分裂出的新单体在移动过程中，逐渐向成发展，并且又分裂出新的单体。
