您要查找的是不是:
- A proton or a neutron, especially as part of an atomic nucleus. 核子质子或中心,尤指作为原子核的一个组成部分
- The total angular momentum of an atomic nucleus. 原子核的角动量之总和。
- The sum of the number of neutrons and protons in an atomic nucleus. 原子核中中子和质子数之和。
- Their idea was that a normal star implodes until its core reaches the density of an atomic nucleus. 他们认为,正常的恒星必须在其核心密度增加到与原子核密度相当时,才会爆炸。
- These high-energy gamma rays, detected by Fermi's Large Area Telescope (LAT), have wavelengths one-thousandth the size of an atomic nucleus. 这些“费米大天区望远镜(LAT)”所侦测到的高能伽马射线的波长仅相当于原子核大小的千分之一。
- The natural or induced transformation of an atomic nucleus from a more massive to a less massive configuration by the emission of particles or radiation. 蜕变,衰变在自然或外界引发下,原子核通过释放粒子或辐射而由重原子核转为相对较轻的原子核。
- Alternatively, wormholes might naturally come into existence on tiny scales, the so-called Planck length, about 20 factors of 10 as small as an atomic nucleus. 另一种可能性则是,蠹孔可能在普朗克长度(约10-33公分)这种极微的尺度下自然存在,这可是只有原子核的1/1020那麽小。
- Similarly, the properties of a qubit are independent of its specific physical representation as the spin of an atomic nucleus, say, or the polarization of a photon of light. 同样地,一个量子位元的性质也独立于特定的物理表现系统,例如原子核的自旋态或光子的偏振。
- Existing or acting outside the nucleus of an atom. 原子核外的出现或行动于原子核外的

- a proton or a neutron,especially as part of an atomic nucleus 质子或中心,尤指作为原子核的一个组成部分
- An atomic or a nuclear bomb. Used with the. 原子弹原子弹或核弹。与the连用
- There isn't an atom of truth in the rumour. 谣言中没有丝毫的真实性。
- An atom bomb would destroy a city. 一颗原子弹能摧毁一座城市。
- A proton or a neutron, especially as part of an atomic nucleus 核子质子或中心,尤指作为原子核的一个组成部分
