黄心木基本密度

本数据记录了黄心木中基本密度的序号、记录本序号、试样序号、试样弦向尺寸、试样径向尺寸、试样顺纹方向尺寸、最大体积、烘干后试样重、基本密度等记录。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 number of basic density entries, logbook serial number, test specimen serial number, tangential dimension of the specimen, radial dimension of the specimen, dimension along the grain direction, maximum volume, post-drying specimen weight, basic density and other related records. Various measured physical and mechanical properties of wood directly reflect the strength and other characteristics of this yellow-heartwood species, providing scientific data for wood utilization and the formulation of wood structural specifications. This database contains physical and mechanical property data and their corresponding test methods (please refer to Attachment 1: National Standard of the People's Republic of China GB 1927–1943-91 "Test Methods for Physical and Mechanical Properties of Wood", and Attachment 2: Definitions of various items for wood physical and mechanical properties).
