煤炭实验室运用χ^(2)检验开展人员比对试验的探究

Discussion on usingχ^(2) test to carry out personnel comparison test in coal laboratory

在煤炭采制化实验室中,采用χ^(2)检验法对制样人员之间的操作水平进行显著性分析,判断不同人员因技术能力对检测结果造成的影响;有助于加强煤炭采制化实验室的内部质量管控,保持实验室检测能力,提升实验室检测水平。

In the laboratory of coal mining and chemical industry,χ^(2) test method was used to analyze the operation level of sample preparers,and to judge the influence of technical ability of different personnel on the test results.It is helpful to strengthen the internal quality control of the coal mining,manufacturing and chemical laboratory,maintain the testing ability and improve the testing level of the laboratory.
