制造零件时使用的材料合金含量通常应准确符合标明的等级,因此应严格加以检测。可是这种检测并不简单,因为合金中可能有多种成分,而且每种合金成分的比例也是多变的。通常这类检验是通过分析合金蒸气光谱的方法来实现的,因为组成合金的每种元素,能产生组合光谱线。为此,分析中 Materials used in the manufacture of parts should generally be alloyed to the exact grade indicated and should therefore be tested strictly. However, this test is not simple, because the alloy may have a variety of components, and the proportion of each alloy composition is also changing. Often this type of inspection is done by analyzing the vapor spectrum of the alloy, as each of the elements that make up the alloy produces a combined spectral line. To this end, the analysis
