摘要

由于我国木材物理和力学强度试验标准与外国不同，很难互相比较和直接应用，因此本文提供了换算系数。同时重点提出美国木材密度试验方法ＡＳＴＭＤ５２与我国国标的换算值，旧国标ＧＢ１９３３－８０和新国标ＧＢ１９３３－９１的换算系数。木材密度是木材物理力学性质的标志，可以通过它推算出多种力学强度数据。本文根据以往的试验数据统计分析得出换算系数

Abstract

Wood density is considered as the most simple indicator of wood mechanical properties. It is widely recognized that there exists correlation between wood density and wood mechanical properties. However,it is difficult to compare with the data of wood density and mechanical properties from different countries for the different test methods being used. In this paper, conversion coefficients are presented for comparison between the data derived from Chinese Standards and American ones(ASTM).
