The objective of this study is to compare three nondestructive methods for evaluating the bending modulus of elasticity(MOE),modulus of rupture(MOR) and compressive strength parallel to grain(σ_c) of Eucalyptus grandia×E.
首先采用3种无损检测设备获得无疵小试样的动态弹性模量,然后进行抗弯弹性模量(MOE)、抗弯强度(MOR)和顺纹抗压强度(σc)的测定,并分析3种无损检测结果与木材强度性质的关系。
In the experiments, the principal research is in proceeding timber softening, longitudinal compressing and molding fixing.
在实验中，进行了木材的软化、木材顺纹压缩和弯曲定型，这也是该课题研究的主要方面。
Depending on bending theory and according to the process of wood multi-direction bending, the experiments are carried out about timber soften, longitudinal compressing, multi-direction bending and dryness finalization and mesurate the minimum radius.
在探讨理论依据和弯曲可行性的前提下，按照木材压缩弯曲的流程进行了木材软化、顺纹压缩、多向弯曲和干燥定型实验，测定了最小曲率半径。
