中文摘要：
研究了用石蜡油法，溴化钾压片法对氟硅酸钠，氟硅酸钾的红外分析，得到了不同方法制得的红外谱图，确定了氟硅酸钠，氟硅酸钾吸收峰的位置。通过红外谱图分析，结果表明：氟硅酸钾的含量与其特征峰的吸收强度呈良好的线性关系，对氟硅酸钾做了简单的定量分析，得到相关系数达0．99以上。
英文摘要：
This paper study about the methods of Liquid Paraffin and Pressure of potassium bromide which are based on the Fra- IR spectroscopy of the sodium fluosilicate and potassium silico -fluoride. The different infrared spectra figures of the sodium fluosilicate are obtained by the methods of Liquid Paraffin and Pressure of potassium bromide. Beside, according to the quantitative analysis of potassium silicofluoride, the result shows that these are in the good linear relationship of the potassium of Fluorine silicon and the intensity of absorption of the characteristics. The relative coefficient is 0.99.
