研究了KH_2PO_4、KD_2PO_4、NH_4H_2PO_4溶液、H_2和D_2O对激光的折光性。测定了它们对He-Ne激光和钠光的折光率温度系数及色散能力。确定了不同溶液折光指数与浓度的关系。单独给出了几种饱和溶液的折光规律,并用激光纹影法精确测定了相应溶液的饱和度数据。
The refractive index of KH_2PO_4, KD_2PO_4, NH_4H_2PO_4 solution, H_2 and D_2O on laser were studied. The refractive index temperature coefficients and dispersion capacities of He-Ne laser and sodium light were measured. The relationship between the refractive index and the concentration of different solutions was determined. The refractive laws of several saturated solutions are given separately and the saturation data of the corresponding solutions are accurately measured by laser profiling.
