The computation formula ( multi - point method ) is studied to estimate its value by mathematical regression analysis 本文运用数学回归分析的方法，研究了估算此参数的计算公式即多点法。

Much experiment data indicates that the single - point method and multi - point can both applied to estimate its value and their precision is very high 大量室内实测数据验证结果表明单点法和多点法都可以应用于计算质量吸收系数的值，且具有较高的计算精度。
