摘　　要：试样用（Ｎａ２ＣＯ３＋Ｂ２Ｏ３）混合熔剂熔融，熔决用ＨＣｌ与Ｈ２Ｏ２浸取，在浸取液中加入Ｋ２Ｃｒ２Ｏ７作内标，制成试样溶液，将此溶液取０．０５ｍｌ，滴到φ４的平头电极上，将溶液蒸干，用交流电弧激发，中型石英摄谱仪摄谱、测量黑度、绘制坐标轴为△Ｓ与ｌｇｃ相对应的工作曲线．方法有较高准确度，操作简易、快速．The analysis method is as following: at first, the sample is melted in mixed solvent(Na2CO3+B2O3),next the clinker is immersed in the HC; and H2O2 solution. K2Or2O7 isadded in the solution as internal standard'0.05ml of this solution is taken to put on the 4 flat head electrode, when the solvent evaporate dry, excite with alternating current are,end the spec trum photography was taken for further anclysis.The methods is of higher accuracy and easilyand quickly operating features.
