摘　　要：本文研究了对人脊柱C3段椎骨应力松弛力学性质,为临床提供生物力学参数;以自动控制电子万能试验机测定了脊柱C3段椎骨应力与时间的变化规律;根据线性粘弹性理论拟合了试验曲线,得出了应力松弛方程;结果表明:C3段椎骨7235应力松弛量为0.232MPa其为粘弹性材料。objective In this paper we did research on the mechanics property of the extending stress relaxat-ion experiment of human cervical spine C3 segment, provided parameter of biomass for clinical. Methods Measure the stress-time and strain-time of human cervical spine C3 segment relationships and regularity. Results By viscoelastic properties theory regressed the experimental curve. Obtained the extending stress relaxation of C3 segment. Conclusions the extending stress relaxation quantity of human cervical spine C3 segment is %, and it is viscous and stretch material.
