摘　　要：从理论上分析了连续光（ＣＷ）辐射下超导外延膜样品的温度场分布情况，具体研究了热交换系数、热导率以及衬底的厚度等因素对超导膜上温度增量ΔＴ的影响．一方面给出了超导样品温度分布的物理图象，另一方面也为热探测器的研制提供有益的参考．Abstract The temperature contribution of epitaxial films with laser(cw) radiation is analysised theoretically, and the effect of the parameters, such as the heat exchange coefficient, the heat conductivity, and the thick of film etc., on temperature increment Δ T is concretely studied. The result not only clearly show the physical picture of the temperature contribution of epitaxial films, but also supply benefitful reference for developing the heat radiation detector.
