Measurement Methods and Development of Wood Microfibril Angle
Yanhui Huang · Xibei Linxueyuan xuebao · 2006
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.
