导出了一维介观系统隧道结的以非平衡格林函数（闭路格林函数）表示的电流散粒噪声谱密度表达式。
Abstract We have derived the expression of the spectral density for the current shot noise in terms of the nonequilibrium Green's functions(closed path Green's functions) for a one dimentional mesoscopic junction, and performed numerical calculations to discuss the dependence of the zero frequency spectral density for the currentshot noise on other variables when the tunnling junction is pure or impure.
