摘要
通过试验，实现了ＩＴＨＡＣ－２００２仪对金属铬中氢的测定。对分析电流，分析时间，脱气电流，脱气时间，梯度时间等进行了逐一选择。方法标准偏差为０．４６％，变异系数为３．３６％。
In the experiment,the ITHAC-2002 was used to determine H_2 in metal chrome,Op-tions of analysis current,analysis time,degassing current,degassing time and gradient time were made one by one. The standard deviation was 0.46%and variation factor 3.36%.
