Kramers的经典理论的激活事件的速率的量子模拟。通过路径积分方法，计算了有限温度下量子力学粒子与热浴耦合的势垒穿越率的相关函数表达式。由于热浴的摩擦影响，隧道效应大大减弱。
The quantum analog of Kramers's classical theory of the rate of activated events is presented. By means of a path-integral approach, the correlation function expression for the rate of barrier crossing by a quantum mechanical particle coupled to a heat bath is evaluated for finite temperatures. Tunneling effects are dramatically diminished by the frictional influence of the heat bath.
