目前由于脉冲加热技术广泛被应用于金属中气体分析领域中,为金属中气体分析的热源创出了一条新的途径,显示了它的优越性。金属及合金中氢的测定,通常于真空或惰性气氛熔化试样或加热到1000～1450℃之间抽取氢。熔化法虽可以同时测定氧,但由于从总的抽取出的气体中求氢的含量是沿用以前的办法, At present, as the pulse heating technology is widely used in the field of metal gas analysis, it creates a new way for the heat source of metal gas analysis and shows its superiority. Determination of hydrogen in metals and alloys. Hydrogen is usually extracted by melting the sample in a vacuum or inert atmosphere or by heating to between 1000 and 1450 ° C. Although the melting method can determine oxygen at the same time, since the content of hydrogen extracted from the total extracted gas follows the previous method,
