n.核原形质核浆

The nucleoplasm is surrounded by the nuclear envelope. 核质被核膜包裹。

At this phase condensed, deeply staining chromatin masses are often seen in the nucleoplasm. 在紧缩期间，核质中的物质可以分为异染色质和常染色质。

In the nucleoplasm chromosomes consisting of deoxyribonucleic acid (DNA) and proteins are present. 核质中的染色体由脱氧核糖核酸（DNA）和蛋白质构成。

Although they are generally found in the nucleoplasm, they also shuttle between the nucleus and the cytoplasm. 尽管它一般发现于核质，但也在胞核与胞质之间穿梭。

Firstly,this paper picks up area characters of the object including area,bary centeric moment,the round degree,slightness degree and nucleoplasm ratio of the geometrical modality. 先提取目标物体的面积、中心矩、圆形度、细长度、核浆比等区域特征。
