本文研究了有限温度下Tomonaga-Luttinger模型的单电子绿色函数的谱函数，该模型只包含前向散射的相互作用。谱权，这是计算作为频率的函数与固定波数，显示。由电荷和自旋涨落的激发谱产生的几个峰随着温度的升高而合并成一个峰。
We examine the spectral function of the single electron Green function at finite temper ature for the Tomonaga-Luttinger model which consists of a mutual interaction with only forward scattering. The spectral weight, which is calculated as a function of the frequency with fixed wave number, shows. that several peaks originating in the excitation spectra of charge and spin fluctuations merge into a single peak by the increase of temperature.
