水曲柳硬度

本数据记录了水曲柳中硬度的序号、记录本序号、试样序号、含水率、试验时端面硬度、含水率15%时端面硬度、试验时弦面硬度、含水率15%时弦面硬度、试验时径面硬度、含水率15%时径面硬度等记录。木材物理力学的各项测定指标，直接反映此种木材的强度等特性，为木材利用和木结构的规范等提供科学数据。本数据库包括物理力学数据和其试验方法（请参看附件1中华人民共和国国家标准GB1927～1943-91《木材物理力学性质试验方法》，附件2木材物理力学各个项目的定义）。This dataset records the serial numbers of hardness tests, log serial numbers, specimen serial numbers, moisture content, end hardness during testing, end hardness at 15% moisture content, tangential hardness during testing, tangential hardness at 15% moisture content, radial hardness during testing, radial hardness at 15% moisture content, and other related records for Fraxinus mandshurica. All measured physical and mechanical properties of wood directly reflect the strength and other characteristics of this wood species, providing scientific data for wood utilization and wooden structure code formulation. This database includes physical and mechanical test data and their corresponding test methods (please refer to Attachment 1: Chinese National Standard GB 1927~1943-91 "Testing Methods for Physical and Mechanical Properties of Wood", and Attachment 2: Definitions of various items for wood physical and mechanical properties).
