用Mie理论计算了任意尺寸和材料的球的原位电偶极子极化率。这种与尺寸相关的极化率，与克劳修斯-莫索蒂方程一起，对非零尺寸球体的麦克斯韦-加内特方程进行了有效的偶极推广。计算出的有效光学常数用于计算银球悬浮液的反射率。结果与Lee等人最近的反射率测量结果很好地吻合。[j] .化学工程学报，1999,17(1):1 - 2。
The Mie theory is used to find the in situ electric dipole polarizability of a sphere of arbitrary size and material. This size-dependent polarizability, together with the Clausius-Mossotti equation, yields an effective dipole generalization of the Maxwell Garnett equation for spheres of nonzero size. Calculated effective optical constants are used to find the reflectance from a suspension of Ag spheres. The results are in good agreement with the recent reflectance measurements of Lee et al.[Phys. Rev. B 37, 2918 (1988)] on porous glass media containing Ag particles.
