摘　　要：探讨采用多项式λ＝ｂ０＋ｂ１ｌｇＮ＋ｂ２ｌｇ２Ｎ逼近ＮＲ／ＢＲ共混硫化胶料疲劳破坏曲线。结果表明，试验值与理论值吻合良好，相对偏差的绝对值小于或等于２４５２％，且分布较均匀，相关系数均大于或等于０９９８８。表明该多项式方程可描述ＮＲ／ＢＲ共混胶料的疲劳断裂曲线。The fatigue failure curves of NR/BR blend were fitted with polynomial λ = b 0 + b 1 lg N + b 2 lg 2 N .The results showed that the calculated values were in agreement with the measured data;the fractional errors were homogeneously distributed and their absolute values were less than or equal to 2.452%;the correlation coefficients were greater than or equal to 0.998 8;and the polynomial equation could be used to describe the fatigue failure curves of NR/BR blends.
