摘要： 论述了某种蜂窝复合板表面气动加热热流的模拟试验方法以及由试验结果确定温度分布和有效导热系数的分析计算方法。由于要求的气动加热热流随时间历程的变化十分剧烈（低热流为零，高热流超过１５个大阳常数），再加上蜂窝复合板的复杂结构，模拟试验与导热系数的计算有一定的难度，文章阐述了一种具有较高模拟精度的热流模拟方法与确定导热系数的分析处理方法。

Abstract: An areodynamic heating simulation test method on a honeycomb platesurface and its numerical calculation method to derive the temperature distributionwith time and the thermal conductivity are discussed. It's a challenge to make the testand calculate the thermal conductivity because of the simulated heat flux varying process so quickly with time as well as its complicated structure. An more exact heat fluxsimualtion test method and numerical treatment method are presented here.
