叙述了脉冲加热、惰性气氛熔化法测氢的原理及有关试验条件的选择。结果表明，用Ｓｎ作熔池，选择合适的功率（Ｔｉ、Ｚｒ、Ｈｆ为２５００Ｗ，Ｔａ、Ｎｂ为２７００—２８００Ｗ）、试样量和加热时间（Ｔｉ、Ｚｒ、Ｈｆ及其合金３０ｓ，Ｔａ、Ｎｂ及其合金４０ｓ），可对Ｔｉ、Ｚｒ、Ｈｆ．Ｔａ、Ｎｂ及其合金中的氢进行分析，该法准确度高，优于真空热提取法。
he principle and optional conditions of inert gas fusion (impulse heating) method for determination of hydrogen with Sn-flux are described. The results show that the method for determinating hydrogen in Ti. Zr. Hf. Ta. Nb and their alloys is accurate. The POwer for analysing are 2500W for Ti. Zr and Hf and 2700-2800W for Ta and Nb. The heating-times are 30s for Ti. Zr and Hf and 40s for Ta and Nb, respectively.
