本文利用真空热扩散和气相色谱分析技术研究了几种工业铝合金表面氢与体内氢的分离方法。结果表明,利用成对的表面积与重量之比不同的样品,分别测出其总氢含量,再通过解二元一次方程,可合理地求出固态铝合金的真实氢含量。
In this paper, vacuum thermal diffusion and gas chromatography analysis of several industrial aluminum alloy surface hydrogen and hydrogen separation method. The results show that the true hydrogen content of solid aluminum alloy can be calculated reasonably by the solution of binary equation by using the samples with different surface area and weight ratios.
