摘要
采用金氏(Janka)硬度测定法测试了不同竹龄毛竹以及毛竹材根部、中部、梢部的硬度并对测试方法做了分析探讨。研究结果表明,不同竹龄毛竹材除当年生的以外,硬度的差异不显著,10年生的毛竹材硬度达到最大;毛竹材各部位的硬度随竹秆高度的增加显著提高,这种变化趋势与竹龄无关。
The Janka hardness of Moso bamboo in different ages and at the bottom,middle and top part of culm was tested and analysed in this paper.The results showed that the hardness value had little difference among the different eight ages except for the one year-old bamboo.The maximum value of hardness is in the ten-year old.The hardness value increased from the bottom to the top of culm obviously and this trend had nothing to do with ages.
