| 摘 要： | 在以前用偏振荧光法测定正常材纤维素非晶区取向度的基础上，对马尾松材应压木应压区、对照区的取向度作了系统的测量，结果表明非晶区的取向度有一定分布规律，特别是早、晚材应压区的取向度均大于对照区，并对此作了初步的分析。

| Abstract: | Based on our previous determination of the degrees of orientation of cellulose non-crystalline region in normal wood using the polarized fluorescence spectrophotometry, the same measurement has been made systematically in the compression and the opposite woods of masson pine (Pinus massoniana). The results showed that the diversities of orientation of cellulose non-crystalline region a-mong the growth rings and between the compression and opposite woods followed certain regularities, especially the degrees of orientation in compression wood were higher than those in opposite wood in both early and late wood, the reason for this difference has been discussed. |
