thermal-diffusion length

In this paper, the effect of thermal insulator structure in a 100 W copper vapor laser of large discharge tube diameter ( 6.5 cm) on the length of the lasing region is discussed.

讨论了放电口径在6cm以上的100W铜蒸气激光器绝热结构对管壁温度分布的影响，从而对其有效增益区长度的影响。

Simplified analysis on a single fiber fin in the duct flow demonstrates that the heat transfer can be enhanced with the increasing length-to-diameter ratio and thermal conductivity ratio.

对单根纤毛肋进行的简化理论分析表明纤毛长径比和肋材与流体的导热系数比越大其强化换热作用越好。
