摘要
由于钢精粉样品均匀性差,成分分析数据误差大,因此对样品进行了预处理,经试验表明,分析成分偏差在0.003%~0.0786%之间。结果的准确度和精密度均符合标准要求。
Due to poor uniformity of steel powder samples, there was a large error in the analysis data of compositions, and so the pretreatment of samples was carried out, then the experiment showed that the deviation of composition analysis was between 0. 003% and 0. 0786%. The accuracy and precision of results conformed to the standard requirements.
