该文导出了平行光入射辐射穿过半透明界面,在吸收、发射性介质内产生的辐射热源的表达式.数值模拟了瞬间激光脉冲入射下:(1)半透明介质与不透明介质在非人射面上的过余温度响应;(2)入的激光的波长对温度响应的影响;(3)界面光学特性(两侧均为不透明界面,两侧均为半透明界面,一侧为半透明、另一侧为不透明界面)对温度响应的影响;(4)采用Planck、Rosseland平均吸收系数处理非灰介质时,对辐射与导热瞬态耦合换热的影响.“,”The radiative source term in absorbing, emitting medium, which is caused by collimated incidence through semitransparent boundary, is deduced in this paper. When a short-time laser pulse irradiate the surface of a medium, the following contents are simulated : (1) excess temperature response at non-incident side of semitransparent or opaque medium; (2)the influence of incident wavelength on temperature response; (3) the influence of boundary optical characters on temperature response (for example two opaque boundaries, two semitransparent boundaries, or one semitransparent boundary and one opaque boundary); (4)the influence on transient coupled radiative and conductive heat transfer in non-gray medium by employing the Planck, Rosseland mean coefficients.
