The structure parameters, such as the correlation distance a c, average chord lengths , mean square radius gyration g, and integral invariant Q were obtained based on Debye-Bueche scattering theory.

• 用Debye Bueche光散射理论的结构参数 ,如相关距离ac、平均弦长 l、旋转半径 Rg 和积分不变量Q等表征了合金中分散相的尺度及其分布在连续相中的均匀性 ,用扫描电子显微镜 (SEM )定量测定了合金中分散相尺寸的大小和尺寸分布。
