非标准大气压下卷烟纸阴燃速率的修正研究

Research on the correction of smoldering rate of cigarette paper under non-standard atmospheric pressure

为了修正非标准大气压下与标准大气压下卷烟纸阴燃速率之间的系统性差异,在6家不同大气压下的实验室(5家非标准大气压实验室和1家近似标准大气压实验室)中对4种卷烟纸样品进行阴燃速率测试,分析大气压与卷烟纸阴燃速率之间的相关性,建立非标准大气压下卷烟纸阴燃速率的修正方程,并验证该方程的可行性。结果表明:1)卷烟纸阴燃速率与大气压呈正相关,R^(2)为0.8572~0.9141,且4种卷烟纸样品的阴燃速率与大气压的相关性均达到极显著水平;2)非标准大气压条件下卷烟纸阴燃速率的修正方程为r_(c)=r_(m)×(0.8157×√P_(0)/P_(1)+0.1936);3)实验样品在非标准大气压下阴燃速率的修正值与标准大气压下的阴燃速率无显著差异,且验证样品在阴燃速率的修正值与其在标准大气压下的阴燃速率的最大偏差绝对值仅为0.170,说明所建立的修正方程可用于修正非标准大气压下卷烟纸的阴燃速率,以消除非标准大气压与标准大气压下测试结果之间的系统性差异。

In order to modify the systematic difference between the smoldering rate of cigarette paper under nonstandard atmospheric pressure and standard atmospheric pressure,four experimental samples were selected for smoldering rate in six laboratories with different atmospheric pressure(five non-standard atmospheric pressure laboratories and one approximate standard atmospheric pressure laboratory).According to the test results,the correlation was analyzed between atmospheric pressure and the smoldering rate.The correction equation was established for smoldering rate to non-standard atmospheric pressure,and the feasibility was verified.The results showed that:1)The smoldering rate of cigarette paper was positively correlated to atmospheric pressure,R^(2) ranged from 0.8572 to 0.9141,and the correlations between the smoldering rate in the four samples and atmospheric pressure all reached extremely significant level.2)The correlation equation between the smoldering rate of cigarette paper to atmospheric pressure was r_(c)=r_(m)×(0.8157×√P_(0)/P_(1)+0.1936);3)The correction values of the experimental sample under non-standard atmospheric pressure was not significantly different from the smoldering rate at standard atmospheric pressure,and the maximum absolute deviation between the corrected value of the verified sample and the smoldering rate of the sample at standard atmospheric pressure was only 0.170.It showed that the correction equation could be used to correct the smoldering rate of cigarette paper under non-standard atmospheric pressure and eliminate the systematic difference between non-standard atmospheric pressure and standard atmospheric pressure.
