摘要
根据中国、日本、美国的外观分等标准对落叶松试材进行了以强度为基础的外观分等,然后对试材进行应力波检测,分析比较不同外观分等结果与应力波检测的相关关系。
According to the standards for the classification by appearance in China, Japan and America, larch test pieces are classified by appearance based on strength and are inspected using stress wave. The relations between different classifications by appearance and stress wave inspection in the above three countries are analyzed and eompared.
