折光率油液的配制方法及其有关的学理,在好些書刊上均有介紹。今將我們在进行这一工作中的点滴体会結合实驗材料,介紹于下,供同志們参考。混合油液的折光率及其圖解实驗已有証明,兩种不同折光率的油液混合后所得的混合油液;其折光率必介于前二者之間,故亦可 Refractive index oil preparation methods and related theories, in a number of books are introduced. Now we will do some work in this experience combined with experimental materials, introduced in the next, for the comrades for reference. The refractive index of the mixed oil and its graphic experiments have shown that the mixture of two different refractive index of the oil mixture obtained; the refractive index must be between the former two, it is also possible
