| 摘 要： | 连续两年系统地测定了河南烤烟（４０级）各等级烟叶叶片厚度、叶质重（单位叶面积重量），并计算出相应的叶片密度．分析了河南烟叶上述物理特性的规律性，其结果是：叶片厚度的变化范围为７０μｍ～１３０μｍ，下、中、上部烟叶的适中值分别为７５μｍ，９０μｍ，１２０μｍ；叶质重的变化范围为７．０ｍｇ·ｃｍ－２～１３．０ｍｇ·ｃｍ－２，下、中、上部烟叶的适中值分别为８．０ｍｇ·ｃｍ－２，９．５ｍｇ·ｃｍ－２，１１．５ｍｇ·ｃｍ－２；叶片密度的变化范围为０．９０ｇ·ｃｍ－３～１．２２ｇ·ｃｍ－３，下、中、上部烟叶的适中值分别为１．０４ｇ·ｃｍ－３，１．０５ｇ·ｃｍ－３，１．０１ｇ·ｃｍ－３．

| Abstract: | ccurate and reliable methods have been employed in
the study to determine thickness and weight presquare sneasure and to calculate density of
tobacco leaves of fluecured tobacco(40 grades) of Henan in the past two years. These laws of
physical specific property have been analysed with the following results:the change range of
thickness is 70 m130 m, and the moderate values olugs,cotters,tips of leaves are 75 m,90
m,120 m respectively; the change range of weight presquare measuar is 7.0 mgcm-213.0
mgcm-2,and the moderate values of lugs,cotters, tips, of leaves are 8.0 mgcm-2, 9.5 mgcm-2,
11.5 mgcm-2 respectively; the change range of density is 0.90 gcm-31.22 gcm-3, and the
moderate values of lugs, cotters, tips of leaves are 1.04 gcm-3, 1.05 gcm-3,1.01 gcm-3
respectively. |
