白桦抗劈力

本数据记录了白桦中抗劈力的序号、记录本序号、试样序号、劈力面宽度、试验时含水率、径面破坏荷载、径面抗劈力、弦面破坏荷载、弦面抗劈力等记录。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 following information regarding the cleavage strength of white birch (Betula platyphylla): serial number of the test entry, log number, specimen serial number, width of the cleavage surface, moisture content during testing, radial surface failure load, radial surface cleavage strength, tangential surface failure load, tangential surface cleavage strength, and other relevant test records.

All measured physical and mechanical properties of wood directly reflect the strength and other characteristics of this timber, providing scientific data for wood utilization and the formulation of wood structural codes and related standards.

This database includes physical and mechanical property data and the 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 for the definitions of each item in wood physical and mechanical tests.
