摘　　要：用一维电子密度相关函数方法,分析了国产尼龙-1010不同拉伸比时的SAXS现象,由实验相关函数曲线可算得长周期(L),中间层厚(d_(tr)),片晶层厚(d_?),非晶层厚(A_?),平均片层厚(d),积分不变量(Q),比内表面O_s以及(η_c-η_a)等数值及其变化规律。实验结果表明尼龙-1010的结晶结构是由结晶层、非晶层以及结晶-非品中间层三部分组成。The structures of Nylon-1010 with different draw ratio have been investigated by usingSmall-Angle X-ray Scattering(SAXS). It is shown that by using a simple geometrical cons-truction the following structure parameters can be directly derived from the correlation func-tion the long period(L), the thickness of the crystalamorphous interphase (d_(tr)), the lamellarthickness(d), the 'invariant'(Q), the specific inner surface (O_s), and the electron densitydifference between the core of the crystallites and the amorphors matrix(ηc - ηa). The crystalline Nylon-1010 is probably consisted of three-phases: a crystalline layer, anamorphous layer and a transition zone between amorphous(Ao) and crystalline layer(do).
