A study was conducted on a thermal-noise effect in a two-level and three-level system. It was shown that the effective master-equation approach was very convenient for deriving the transition probability in the strong-damping limit. Using this approach, a formula in the two-level system when the external field was reversed from a large negative value to a large positive value was reproduced.
