杉木基本密度

本数据记录了杉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 serial numbers associated with the basic density of Chinese fir, including log serial number, specimen serial number, tangential dimension of specimen, radial dimension of specimen, dimension along the grain direction, maximum volume, post-drying specimen weight, basic density and other relevant items. Various measured indices of wood physical and mechanical properties directly reflect the strength and other characteristics of this timber, providing scientific data for wood utilization and wood structure code formulation. This database contains physical and mechanical property data and their corresponding test methods (please refer to Appendix 1: National Standard of the People's Republic of China GB1927～1943-91 "Test Methods for Physical and Mechanical Properties of Wood", and Appendix 2: Definitions of each item of wood physical and mechanical properties).
