一、前言由于人们对自身的健康水平和生活质量的更多关怀,已经使生物医学方面的需求越来越明显地成为材料科学发展的重要推动力之一.生物材料(Biomaterial)正是在这种推动力的影响下产生出来的一个新的材料科学分枝,这种材料的使用方式一般是制成人工器官植入人体或作为填充性支持物理入体内.所以,任何一种材料,当其能安全地使用于生物体内的环境中时,它就成为生物材料的一员,与其它工程材料不同,生物材料除了要求一定的物理化学性质(包括力学性质)之外,还要求有良好的生物相 I. INTRODUCTION As biomedical concerns have become more and more apparent as people become more concerned with their own health and quality of life, Biomaterial is where biomaterials A kind of new material science branch which is produced under the influence of kinds of driving forces, and this kind of material is usually used to make artificial organs into the human body or as a filling support body into the body, so any kind of material, Safe to use in the environment of the living body, it becomes a member of biological materials, and other engineering materials, biological materials in addition to require certain physicochemical properties (including mechanical properties), but also requires a good biological phase
