中文摘要：

对东西南北4个不同方向的麻竹竹材的物理和力学性能进行分析，结果表明，不同方向的麻竹竹材的物理和力学性能之间存在一定的差异，但差异均不显著，说明东西南北各个方向对麻竹竹材的物理和力学性能均无明显影响。不同年龄的麻竹竹材的物理和力学性能之间也存在一定的差异，其中在各密度以及顺纹抗拉强度、抗压强度、抗弯强度和抗弯弹性模量方面，均表现为1．5龄〉2．5龄〉0．5龄；在各干缩率和顺纹抗剪强度方面，均表现为0．5龄〉2．5龄〉1．5龄。

英文摘要：

The analysis of the physical and mechanical properties of the Dendrocalamus latiflorus Munro in ＇four directions showed that there were some differences in the physical and mechanical properties in different directions. However, these differences were not significant, which indicated that directions had little effect on the physical and mechanical properties. In addition, there were some differences between the physical and mechanical properties in different ages. All the density, tensile strength parallel to grain, compressive strength parallel to grain, bending strength and MOE were 1.5 age〉2.5 age〉0.5 age. All the shrinkage rates and shear strength parallel to grain were 0.5 age〉2.5 age〉l.5 age.
