摘　　要：以落叶松锯材为试验对象,依据日本JAS235《构造用集成材日本农林规格》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 sawn timber as the experimental object and in accordance with the relevant rules of visual grading detailed in Japanese JAS235 Japanese Agricultural Standard for Structural Glued Laminated Timber, visual grading of plantation larch sawn timber is carried out, with knots as the inspecting and measuring object and a bending failure test of sawn timber after classification is conducted. The correlation between the visual grading results and the bending failure test results is analyzed and compared.
