在室内火灾双区域模型中，对火灾烟气层分界面高度值的判定具有重要意义，对其计算方法进行了研究。鉴于烟熏痕迹法和N百分比法存在的主观性和经验性的局限，介绍了一种积分比值法，给出了计算公式并采用Fortran95实现了编程计算。通过FDS5.0模拟了一种火灾场景，根据模拟得到的不同高度处的温度均值，应用积分比值法计算出了烟气层高度值，并将其与模拟得到的烟气层高度值进行了比较，结果表明两者较为吻合，应用积分比值法计算烟气层高度是可行的、准确的。

In the compartment fire two￣zone model, the judgment of smoke layer interface height value is of important significance, and this paper has conducted the research on the calculation method. In view of the subjectivity and empirical of smoke trace method and N￣ percentage method, this paper introduces a kind of integral ratio method, then its calculation formula is given and programming calculation is realized by Fortran95. A fire scenario was simulated by FDS5. 0. What is more, according to the different heights of mean simulated temperature, the smoke layer height value is calculated by integral ratio method which is compared with the values obtained in the simulations. The results show good agreement and application of integral ratio method, and it is feasible and accurate.
