摘要: 生物力学应用力学原理和方法对生物体中的力学问题进行定量研究。本文把"本构关系"和"应力-生长关系"总结为生物力学的两个核心问题。通过"血浓于水"、"动脉硬化"、 "骨头受力"这3个例子说明本构关系的含义;通过"骨生长"、"硬气功"、"高血压与心血管病"这3个例子说明应力-生长关系的含义。本文内容可以启发读者从身边的事物中体会生物力学的科学道理。

关键词: 本构关系, 应力-生长关系, 自我调节

Abstract: The biomechanics is the science of applying the mechanical principles and methods to quantitatively study mechanical problems in organisms. This paper points out that the constitutive relationship and the stress-growth relationship are the two core issues in the biomechanics. The meaning of the constitutive relationship can be explained by using three examples: the "blood is thicker than water", the "artery hardening" and the "bone under loading"; and the meaning of the stress-growth relationship can be explained by using other three examples: the "bone growth", the "hard Qigong" and the "hypertension and cardiovascular diseases".

Key words: constitutive relationship, stress-growth relationship, autoregulation
