红椿硬度

本数据记录了红椿中硬度的序号、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 for hardness tests, log serial numbers, specimen serial numbers, moisture content, end hardness during testing, end hardness adjusted to 15% moisture content, tangential hardness during testing, tangential hardness adjusted to 15% moisture content, radial hardness during testing, radial hardness adjusted to 15% moisture content, and other relevant records for Toona ciliata wood.

All measured physical and mechanical property indicators of wood directly reflect the strength and other characteristics of this wood species, providing reliable scientific data for wood utilization and wooden structure standard development.

This database includes 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 related to wood physical and mechanical properties.
