摘  要：
本文首次较系统的介绍了木材微纤丝角的近20种测定方法,并将其归为三类:显微技术法、X射线法和近红外光谱预测法。以X射线衍射法为重点,在对各种方法进行仔细分析和优缺点对比的基础上,总结出三类测定方法的特点:显微技术法是获得微纤丝角微观信息不可替代的方法;X射线法测定迅速、重现性好、代表性强,特别适用于大量试样的变异研究;近红外光谱预测法既适用于大量试样的变异分析,又可实现模型共享和多组分快速预测。同时,提出了改进和发展测定方法的建议。

摘  要：
This paper systematically introduced nearly twenty measurement methods of microfibril angle of wood,and divided them into three kinds: microscopic method,X-ray method and near infra-red spectroscopy estimating method.Advantages and shortcomings of all the methods were analized and compared with the emphasis of X-ray methods to gain the strongpoints of the three kinds: microscopic method was the only one for getting the micro-informations of microfibril angle;X-ray method was rapid and repeatable,and its measurement results had good representativeness,so this method was suitable specially for variation research of the massive specimens;the near infra-red spectroscopy estimating method was also suitable for variation analysis,and it might realize model sharing and the multi-component fast forecast.Finally,the improvement and the development suggestions of measurement method were proposed.
