摘　　要：摩托车催化转化器贵金属含量测试属于摩托车产品强制检验项目中使用化学分析方法检验的一个项目,测试得出的数据其有效数字位数的选取和确定、数据记录的准确性以及计算过程和结果数据的处理都会影响到最终结果的准确性,以AAS方法测试为例,简要阐述这些影响结果准确性的因素在实际测试中的具体处理方法。The measurement of precious metals content in motorcycle catalytic converter belongs to a test item using the chemical analysis method of compulsory inspection of motorcycle products. The selection and determination of significant figure of the data obtained through tests, the accuracy of data recording,the calculation process and the processing of the result data will affect the accuracy of the final results.Taking the atomic absorption spectrometry method(AAS) test as an example, the manuscript briefly describes the specific treatment methods of these factors which affect the accuracy of the results in the actual test.
