| 摘 要： | 赤水市几种主要竹种的气干密度与力学性质的关系研究表明各竹种的气干密度与力学性质除部分竹种外均存在一定的曲线或直线关系,其中在气干密度与顺纹抗压强度关系中,除了花吊丝外,其他竹种均可利用回归方程σ=apb、σ=ap+b进行估测.在气干密度与抗弯强度关系中各竹种均可利用回归方程σ=apb、σ=ap +b进行估测.另外,在各回归方程中他们的精确度又存在一定的差异.

| Abstract: | This paper aims to analyze the relationship between air-dry density and mechanical strength of several main bamboo species in Chishui City.It was found that there existed a kind of curve or straight-line connection between the air-dry density and the mechanical properties of various bamboo species.The relationship between the air-dry density and the compressive strength parallel to grain of bamboo species can be estimated by the equation σ=aρb,σ=aρ+b,except for Dendrocalamus minor var.amoenus.The relationship between the air-dry density and bending strength of bamboo species can be estimated by the equation σ=aρb,σ=aρ+b.In addition,there are still some differences in the accuracy of the assessment. |
