摘　　要：本文以氩载气洗提，气相色谱法测定低温核供热反应堆环路冷却水中的微量氢，可测定氢气最低浓度为０．２０ｍＬ／ＬＨ＿２Ｏ，在此浓度下，分析１０次的精密度（相对标差）为１０％。The extracdon and GC analysis of mi-cro amount of hydrogen dissolved in coolingwater of a heat reactor were studied.A sim-ple and rapid procedure for the preparationof aqueous samples for calibration and asampling device were designed.A methodwas given for the correction of the error re-sulted from the escaped nitrogen bubble insampling tube from the nitrogen-saturatedsample, Hydrogen at the concentration of 0.20mL/L H_2O can be determined with a pre-cision of 10%
