铸铁中的磷和镁量,用户的化验室获得的验收结果,常与生产单位化验室的分析结果不一致.美国铸造学会铸铁分会化学分析委员会决定光谱用分析试样,看一看各试验室间分析的磷和镁量的复现率如何?
The amount of phosphorus and magnesium in the cast iron, the acceptance results obtained by the user’s laboratory, are often inconsistent with the analytical results of the laboratory in the manufacturing unit. The Foundry Society of America Casting Branch Chemical Analysis Committee decided to analyze the spectra with a sample and take a look at the inter- What is the rate of recurrence of phosphorus and magnesium analyzed?
