研究了黄纹竹地下部分(竹鞭系统)与地上部分的生长发育规律。
This paper systematically studies the growth rule of Phyllostachys virax, and also discusses the growth rule of monopodial bamboos.
结果表明:竹层积材是一种低湿胀性材料,顺纹、径向和弦向上均远低于木材和LVL。
The results showed that the grading bamboo strand lamination is a low-swelling material. The swelling of parallel to grain, radial and tangential is lower than that of timber and LVL.
实验结果表明,黄竹的物理性能,如纵横干缩性等优于龙竹,而且黄竹的力学性能如静曲强度、静曲弹性模量及顺纹压缩与剪切强度也比龙竹高。
The results showed that Den. membranaceus has better physical properties than that of Den. yunnanicus, such as higher density, lower tangential and longitudinal dry shrinkage.
