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，次级卵母胞又成两个大小不对等胞：一个相对很大卵子（成熟卵胞）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成熟结构，表现较强稳定性，而单体在移动过程中，逐渐向成熟位相发展，并且又单体。
