摘要: <正>采用脉冲声波法测定木材的声速,并对试样进行力学强度试验,求得两者间的回归关系。对影响木材声速的因子以及声速在弦向、径向、纵向三个主要方向上的差异,也作了测定和讨论,并用管状模型作了定性说明。

Abstract: Using the sound pulse method, sound velocities in wood were determined, and after having made tests of the mechanical strength of wood samples, regression relations between sound velocity and compressive strength parallel to the grain of wood were secured. Factors affecting sound velocity in wood and the differences of sound velocities in the three main directions (longitudinal, radial and tangential) of wood were also determined. All this has been qualitatively described with the help of a tubular model.
