摘要
本文采用时间变量τ的双参数表示式:τ=Tω+t,导出了双时间参数热传导方程。用于处理土温日变化时,得出了有进动的土温日波动的双时间参数解析式,从而引入了日平均温度随深度的非线性变化项,改进了迄今通用的但并不合理的线性分布的表示式。
In this paper, the time variable t is expressed in two parameters, from which the bi-time-parameter equation of heat conduction is derived. Dealing with the diurnal variations of soil temperature, the analysis solution of the progressive temperature wave is obtained. Thus, the non-linear distributions of the mean daily temperature varying with the depth of soil is introduced and the linear distribution expression usually adopted but unconformably in solution of the equation is improved.
