| 摘要: |
| 文章采用百度实验法对尾赤桉木材干燥特性进行研究，提出了尾赤桉木材干燥基准，并进行工艺实验研究。结果表明，经此种干燥工艺后，60 mm厚尾赤桉木材初含水率从87.05%降至12.55%，干燥周期为46 d，且除纵裂度较大外，其他可见缺陷干燥质量达到国家标准GB/T 6491—1999《锯材干燥质量》规定的一级要求。 |

| Abstract: |
| The characteristics of Eucalyptus surophylla ? E. camaldulensis lumber by artificial drying at 100℃ were studied. The standard of E. surophylla ? E. camaldulensis lumber drying was proposed. The moisture content of 60 mm thick board decreased from 87.05% to 12.55% by drying. The drying period was 46 days. The quality of the drying board reached the 1st level of national standard GB/T 6491—1999, except big longitudinal crack. |
| Key words: Eucalyptu surophylla?E. camaldulensis, drying technology, drying characteristics |
