摘要
采用指数函数模型λ＝ＡｅｘｐＢｌｏｇＮ拟合４种不同配方ＮＲ／顺丁橡胶硫化胶的疲劳破坏曲线，结果表明，计算值与实测值吻合良好，相对偏差为－２．８３％～２．８９％，且分布较均匀，相关系数为０．９９６６～０．９９９５。
Fatigue failure curves of natural rubber/cis-1,4-polybutadiene rubber vulcanizates at different recipes were fitted with exponential function model λ=Aexp B log N.The result showed that calculated data were in good agreement with the experimental data.The relative deviation values were-2.83%～2.89% with homogeneous distribution, the correlation coefficients were 0.9966～0.9995.
