Although it borrowed from Rutherford's idea of a central atomic nucleus surrounded by orbiting electrons, it made a significant leap.

尽管它借鉴了卢瑟福的中心原子核被轨道电子包围的想法，但它还是取得了重大飞跃。

It represents the electrons in orbits around a small central nucleus.

它代表围绕一个小中心原子核轨道上的电子。

For one, their cells look pretty different. Skeletal muscle tissue has long, multinucleate cells, while cardiac cells are squat, branched out, and interconnected, each one with one or two central nuclei.

首先，它们的细胞看起来非常不同。骨骼肌组织有长的多核细胞，而心脏细胞是蹲下的、分支的和相互连接的，每个细胞都有一两个中央细胞核。

He concluded that an atom’s positive charge was concentrated in a tiny central nucleus, and these nuclei were deflecting alpha particles that bounced off of them.

他得出结论，一个原子的正电荷集中在一个微小的中央原子核中，这些原子核正在偏转从它们身上反弹的 alpha 粒子。
