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.
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.
