摘要: 考虑真空涨落能量为负的特点,提出一个能够简洁描述原子与真空涨落相互作用的方程,得到原子处于激发态的概率随时间变化的关系,讨论了原子自发辐射的速率与真空涨落的强度的关系.

关键词: 二能级原子, 原子自发辐射, 真空涨落

Abstract: An equation for describing interaction of atom and vacuum fluctuation is proposed, because the en- ergy of vacuum fluctuation is negative. It can get the probability of atoms in the excited state changing with time. The relation between the atom' s spontaneous emission and the strength of vacuum fluctuation is discussed.

Key words: two-level atom, atom's spontaneous emission, vacuum fluctuation
