摘要：

Simple conductance formula for small systems with a single superconducting segment is derived through the linear response theory. It is an extension of the Landauer formula. The expression consists of the usual transmission and reflection coefficients as well as the off-diagonal elements which are given by the processes where an electron is reflected to a hole due to the Andreev reflection.
