摘　　要：人造骨是骨科治疗中的新材料,将该材料引入到弯曲法测杨氏模量中,可作为医用物理设计性实验。对人造骨材料杨氏弹性模量测量结果发现其值与生物骨参数较为一致,生物相容性好。笔者还研究了它与湿度、温度及生理盐水浸泡的关系,数据表明该材料的物理稳定性极好。Artificial bone is a kind of new material in orthopedic therapy. Inducting this material in the measurement of Young＇s elastic modulus with bending method can be used as medical physics design experiment. The measurement results of the Young＇ s elastic modulus of artificial bone are coincided with that of biological bone, and indicate that it has fine biocompatibility. The relationship between Young＇ s modulus and temperature, humidity or immersion in physiologic saline, were also researched. The results prove that the physical stability of the material is excellent.
