| 摘 要： | 以我国粗皮桉人工林木材为试验材料,分别采用中国国家标准(GB/T 1933-2009)的直接测量法、X线密度仪和SilviScan木材材性快速测定仪对粗皮桉木材的气干密度进行了测定。结果表明,采用直接测量法、X线密度仪和SilviScan得到的粗皮桉木材试样的气干密度值之间有很好的相关性,并用近红外光谱方法对这些木材密度进行了快速预测,预测效果较好。该研究结果可为将来木材密度快速测定方法的研究和粗皮桉木材的科学合理利用提供依据。

| Abstract: | Three methods were adopted to measure the density of air-dried Eucalyptus pellita wood: direct measurement based on China National Standard Method(GB/T 1933-2009),X-ray densitometry and SilviScan.Good correlation were observed among the density values measured by the methods mentioned above.Satisfactory results were also achieved by using near infrared spectroscopy to predict the density quickly.The results could supply reference for studying the methods of rapid measuring air-dry density and rational utilization of E.pellita. |
