This article generalized the theory of reflectivity between parallel polars of aniso-tropic minerals Ran and formulated for the first time the functional relation between R(11) and the properties of anisotropic rotation. By the formula, the reflectivity between parallel polars of a mineral can be calculated after measuring its principal reflectivity R1 and R2 and the apparent rotation angle of anisotropism Ar.The article, then, formulated the functional relations among the three factors: reflectivity of anisotropic mineral at random position Rψ, reflectivity between parallel polars Ran and reflectivity between crossed polars R+. In the last part of the article, the relative errors between R(11) and R( )45 of the mineral at inexact position of 45° are calculated.
