【摘要】 反应气氛法（RAP）的目的是去除氯化钾中10.6μm处具有高吸收截面的多原子分子/离子杂质。采用锆铝合金吸气剂纯化载气（氩）是必要的。RAP KCl已被分析,其中SO₄^2-、MnO_<sup>-的含量分别为30ppb和<130ppb。利用10.6μm激光卡计测量RAP KCl的光吸收得到β_10.6μm≈4.2×10^-4cm^-1。更多还原

【Abstract】 The aim of reactive atmosphere process（RAP）is to eliminate the polyatomic molecular/ion impurities with high absorption cross section, at 10.6μm in KCl. It is necessary to purify the carrier（argon）by Zr-Al alloy absorbent. RAP KC1 has been analysed in which the contents of SO₄²⁺ and MnO₄^- are 30ppb and <130ppb respectively. The optical absorption of RAP KCl measured by a 10.6μm laser calorimeter, is β_10.6μm≈4.2×10^-4cm^-1.更多还原
