卷烟纸在不同大气压下透气度换算修正方程的建立和验证

The establishment of corrected equations for air permeability of cigarette paper under different atmospheric pressure and validation

卷烟纸透气度的测定值常常随着大气压的变化而发生变化，为满足卷烟工业企业异地加工质量均一性的需求和检测数值的统一性，卷烟企业迫切需要一套能根据不同地点透气度测定值进行换算和比较的方法。目前，这方面虽然有一定的研究报道，但很少进行不同卷烟纸在不同大气压下相互换算的系统性研究和结果验证，结果的准确性难以评价。

The corrected linear equations for air permeability of cigarette paper under different atmospheric pressure was established and validated. According to validated results, the accuracy of the corrected air permeability were greater than 98.2%. Therefore, the method was practical to be used for the determination, correction and comparison of the air permeability of cigarette paper in different regions.
