摘　　要：对黔北地区主要竹种竹材的物理与力学性质的关系研究表明:各竹种的气干密度与抗弯弹性模量以及抗弯强度与抗弯弹性模量均存在一定的曲线或直线关系,其中在气干密度与抗弯弹性模量关系中,除花吊丝竹、毛脚龙竹外,其他竹种均可利用回归方程E12=aρ12b、E12=aρ12+b进行估测。在抗弯强度与抗弯弹性模量关系中所有竹种均可利用回归方程E12=aσ12b、E12=aσ12+b进行估测。另外,各回归方程的精确度存在一定的差异。This paper analyzed the relationship between the physical property and the mechanical character of several kinds of bamboo species in the north of Guizhou province,the results showed that there was a certain curve or linear relationship between the physical property and the mechanical character of different bamboo species.The relationship between the air-dry density and MOE of bamboo species except Dendrocalamus minor var.amoenus,Dendrocalamus barbatus var.internodiiradicatus could be assessed by the follow...
