摘　　要：以落叶松锯材为试验对象,依据美国材料试验协会ASTMD245中外观分等的相关规则,对人工林落叶松锯材进行了以节子为检量对象的外观分等,并对分等后的锯材进行了弯曲破坏试验,分析比较了外观分等结果与其弯曲破坏检测结果的相关关系。With Larch lumber as the experimental subject and according to the visual grading-related rules specified in ASTM D245, the visual grading of plantation larch lumber is conducted, with knots as measurement subject, a bending failure test is carried out after grading and the correlation between visual grading results and bending failure test results are analyzed and compared.

关 键 词：落叶松 目测分等 静态抗弯弹性模量 抗弯强度
