查询词典 nucleus

衰变过程使母核增加或减少一个单位的正电荷而不改变它的质量数。

The neutrino was first postulated in 1930 by Wolfgang Pauli to preserve the conservation of energy, conservation of momentum, and conservation of angular momentum in beta decay—the decay of an atomic nucleus into a proton, an electron and an antineutrino.

中微子是1930年由沃尔夫冈泡利为了保持能量守恒，动量守恒和β衰变---一个原子核（那时还没有认识到是中子）衰变成一个质子、一个电子和一个反中微子的角动量守恒，。

Any of three processes of radioactive disintegration in which a beta particle is spontaneously emitted by an unstable atomic nucleus in order to dissipate excess energy.

某些不稳定原子核为耗散其过剩能量而自发发射一个β粒子的三种放射性衰变过程的统称。

Any of three processes of radioactive disintegration in which a beta particle is spontaneously emit ted by an unstable atomic nucleus in order to dissipate excess energy.

某些不稳定原子核为耗散其过剩能量而自发发射一个β粒子的三种放射性衰变过程的统称。

Red blood cells (also called erythrocytes or red corpuscles; corpuscle is an older term meaning any blood cell) are flat, biconcave discs lacking a nucleus.

Using in vivo intracellular recording technique, we studied the binocularity of the dorsal lateral geniculate nucleus neurons in the monocular eyelid sutured cats. We found that almost all the neurons responded to the flashing spots to the nondominant eyes, and there was no significant difference of the response properties between the neurons in the deprived and non-deprived layers.

采用在位胞内记录技术，研究了单眼视觉剥夺猫外膝体神经元的双眼反应特性，结果发现单眼剥夺猫外膝体几乎所有的双眼反应神经元都对非优势眼的闪烁光斑刺激有不同程度的反应，并且剥夺层和非剥夺层神经元在反应特性上没有明显差异。
