摘要：重点研究和详细介绍了利用纳米压痕技术测试管胞次生壁S2 层纵向弹性模量以及硬度的实验技术 ,并测试了人工林杉木早晚材管胞S2 层的纵向弹性模量和硬度。结果表明 :杉木晚材管胞S2 层的平均纵向硬度为0 390GPa ,弹性模量的平均值为 1 4 84 4GPa ;早材管胞S2 层的硬度和模量则小于晚材 ,平均值分别为 0 30 6GPa和9 82 3GPa。
The detailed experimental procedure of using nanoindentation technique to determine the longitudinal elastic modulus and nano hardness of tracheids secondary wall was emphasized, base on which the longitudinal mechanical properties of Chinese Fir tracheids were measured. It was indicated both hardness and elastic modulus of latewood secondary wall were higher than earlywood cell wall. The longitudinal elastic modulus and hardness of latewood tracheids S 2 layer were 14 844?GPa and 0 390 GPa respectively, while and earlywood cell wall S 2 layer had a corresponding value of 9 823 and 0 306 GPa.
