摘要：为了更精确地判定古建筑木构件内部缺陷的等级,对木材用阻力仪检测中影响阻力值的因素进行了研究和探讨。研究结果表明:含水率对阻力值有一定影响,在含水率4%～20%范围内,阻力值随含水率增加而减小,含水率在20%以上,阻力值却有回升;相同含水率下,弦向检测的阻力值略大于径向;年代对阻力值影响不显著;树种、密度和早晚材对阻力值影响显著。
In order to decide internal defects of wood component in historical building more exactly,the influencing factors on the results of resistograph in wood were studied.The results shows：moisture content has a significant effect on resistance,during 4%～20%scopes,the resistance decreases with the increase of moisture content,when the moisture content more than 20%,resistance are rising;Under the same moisture content,the resistance in tangential direction is lower than that in the radial direction;Age does not influence the resistance obviously;Wood species,density and earlylate wood influences the resistance obviously.
