根据Ｓａｎｄｅｒｓｏｎ电负性均衡原理，对烷烃分子中氢的平均正电荷分数、Ｗｉｅｎｅｒ指数与折光率之间的关系进行了研究，提出了烷烃折光率的计算式ｎ２０Ｄ＝ａΔδＨ＋ｂΔｐ＋ｎ′２０Ｄ，计算值与实验值吻合较好
According to the Sanderson electronegativity equalization principle, the relationship between the average positive charge fraction of hydrogen and the refractive index of hydrogen in paraffin molecules was studied. The calculation formula of alkane refractive index n20D = aΔδH + bΔp + n’20D was proposed, The values match well
