摘要:
采用应力波仪和阻力仪分别对雪松进行了材性检测分析。结果表明,由应力波断层扫描得到的图片和阻力仪得到的阻力曲线图比较准确地反映出雪松立木内部的材质分布情况,应力波仪和阻力仪结合在一起对立木内部材性进行检测时,提高了检测结果的准确性,而且很好地弥补了每个设备的不足;通过和实际测量的生材密度相比较,无论是应力波速和雪松密度还是阻力值和雪松密度的相关系数都大于0.8,能够证明应力波和阻力仪所反映的材质材性信息和雪松立木的密度有较好的相关性。

Abstract:
The cedar sample was tested by the technique of stress wave and resistograph. The results showed that the photographs obtained from stress wave and resistograph could exhibit the distribution of cedar sample interior characteristics. Combination of stress wave with resistograph for determination of standing tree interior characteristics could improve the testing accuracy and make up for the deficiency of both instruments. Moreover, there is a good correlation between the information of photographs obtained from stress wave and resistograph and the wood density with more than 0.8.correlation coefficients.
Key words:  stress wave  resistograph  nondestructive test  cedar sample interior characteristics
