摘　　要：成年Ｗｉｓｔａｒ大鼠坐骨神经（ＳＣＮ）１４侧，随机分为２组，分别在半活体和离体两种不同状态下进行单轴拉伸试验，结果表明：当轴向应力在０～３６ｋＰａ范围时，半活体和离休的ＳＣＮ应力应交关系为指数函数关系，但材料常数Ｘａ间有显著性差异（Ｐ＜０．０２）。14 sciatic nerves of rats(SCN) were randomly divided into two groups for the stretching experiments in semi-vivo and in vitro. The results show that the axial constitutive equation of the sciatic nerve can be expressed in the relation of exponential function in semi-vivo and in vitro when the stress is between 0--36 KPa, but the difference between the two groups'material constants(X3) is statistically significant (P<0. 02).
