查询词典 trophic nuclei

Radioactive series: Any of four sets of unstable heavy atomic nuclei that undergo a series of alpha decay and beta decay until a stable nucleus is achieved.

放射性系：四组不稳定的重原子核，通过一系列α衰变和β衰变直至达到稳定的核为止。

Alpha particle s have two positive charges and a mass of four atomic mass units; they are identical to helium nuclei.

因为α粒子有两个正电荷，质量为4，射出后产生的子核的正核电荷和原子序数都比母核小两单位，质量小四单位。

Some nuclei, especially heavier ones, are unstable , or radioactive, emitting energy in the form of alpha rays, beta rays, or gamma rays.

有些原子核并不稳定，特别是较重的核，或称具有放射性，以α射线、β射线或γ射线的形式发出能量。

Some nuclei, especially heavier ones, are unstable, or radioactive, emit ting energy in the form of alpha rays, beta rays, or gamma rays.

有些原子核并不稳定，特别是较重的核，或称具有放射性，以α射线、β射线或γ射线的形式发出能量。

Fifteen years later, by bornharding with alpha rays certain of the lighter atoms, nitrogen and aluminium for example, Lord Rutherford demonstrated the ejection of protons, or positively charged hydrogen nuclei

15年后他用a射线轰击某些较轻的原子，如氮原子和铝原子，向人们展示质子，即带正电荷的氢核的排斥现象。

Amitosis Nuclear division characterized by the absence of a nuclear spindle and leading to the production of daughter nuclei with unequal sets of chromosomes.

无丝分裂：是一种比较简单的分裂方式。

Amitosis began with a transversal constriction of nucleus to form dumb bell shaped nucleus which later split into two daughter nuclei, and completed with the separation of cytoplasm to form two new cells.

无丝分裂过程先是细胞核中部缢缩形成哑铃状细胞核，然后分裂成两个子细胞核，最后细胞一分为二、完成细胞分裂。

RESULTS: Forebrain beta-EP neurons were found mainly in and around the arcuate nuclei of normal rats, with small number of neurons also identified with weak postivity in the cerebral cortex and amygdaloid complex.

结果：正常大鼠前脑β-EP神经元主要分布于弓状核及其周围，在大脑皮层和杏仁复合体也显示了少量β-EP弱阳性神经元。
