摘　　要：利用脉冲惰气熔融库仑定氧仪对试样进行条件试验,找出了不使用贵金属铂的最佳条件,结果表明,测试数据准确可靠,重现性良好、偏差小,方法简便快速。By means of Colometric oxygen analyzer of pulse inert atmosphere melting, we studied test condition for samples and found out the optimum conditions without using noble metal of platinum. The result shows that test data are accurate and reliable with good repeatability and small deviation. The method is simple and quick.
