摘　　要：氮是人造金刚石晶体中最常见的杂质,它以可替代方式固溶于人造金刚石中,氮杂质作为人造金刚石的最主要结构缺陷,对晶体本身的光学、热学、电学和机械性能有着重要影响,进而影响其在工业发展和高科技领域中的潜在应用前景[1,2]。A method for the simultaneous determination of oxygen and nitrogen in synthetic diamonds by inert gas high temperature extraction-impulse heating method was proposed. The sample weight, the selection of analysis power and the calibration curves of oxygen and nitrogen were discussed. Oxygen and nitrogen in analytical samples are determined. Values of RSDs （n=7） for oxygen and nitrogen were less than 4. 5% and 4. 0% respectively. The analytical results of oxygen and nitrogen obtained by the proposed method were in good agreement with those by inert gas fusion-impulse heating method.
