virtual particle

虚粒子

...由于U(a)的积分（求和）是发散的。为得到收敛的结果，数学上人为地引入一个切断因子。在物理学里，虚粒子(virtual particle)是存在于极短的时间以及空间内。由于测不准原理的关系，虚粒子的能量与动量都是不确定的。

abstract: In physics, a virtual particle is a transient fluctuation that exhibits many of the characteristics of an ordinary particle, but that exists for a limited time. The concept of virtual particles arises in perturbation theory of quantum field theory where interactions between ordinary particles are described in terms of exchanges of virtual particles.
