摘要
从高分子材料的时间－温度等效、应力－时间等效及应力－温度等效的原理出发，首次对著名的ＷＬＦ半经验方程进行了理论推导并使该方程中经验的Ｃ１．Ｃ２参数得到了具有明确物理意义的表达式．此外还结合３０多种高分子材料的Ｃ１，Ｃ２值讨论了固有活化能△Ｅ．
In this paper, for the first time the famous W.L.P equation will be inferred by the equivalency between time and temperature, stress and time, stress and temperature. The experienced parameters c1, and C2 will be experssed by definite formulas and the relation between the intrinsic activation energy △Eo and the parameter of temperature sensitivity rand flexibility of polymers will be discussed by the C1 and C2 of the thirty kinds of polymer materials.
