摘要：

A theory is presented to calculate the changes in the optical properties of a solid in the presence of a nonuniform perturbation. The treatment has general validity and shows that the spatial variation of the perturbation not only results in changes of spectral lineshapes due to averaging effects, but also causes an apparent mixing of the real and imaginary parts of the dielectric function. This effect is readily observable in electroreflectance at fundamental edges and accounts for many experimental observations.
