摘要：

We give a diagrammatic algorithm for calculating the reaction rate of a generic process taking place in a thermal reservoir in equilibrium. The derivation is performed by introducing a specific path in the complex-time plane and employing the path-integral method, and thus the algorithm is formulated within the framework of a real-time thermal field theory.
