摘要
通过实验室与现场测试验证了不同行业工况下烟尘颗粒物对基于β射线法烟尘直读仪的数据影响分析,分析了实验室验证数据产生负偏差的原因及解决措施,综合实验室与现场验证数据得出β射线法的烟尘直读仪测量数据不仅准确度高,而且与重量法数据相关性高,说明了β射线法烟尘直读仪不受不同行业工况的烟尘颗粒物影响。
Through laboratory and field tests,the causes of the negative deviation of laboratory verification data are analyzed.The verification data shows that the measurement data of theβ-ray method is not only highly accurate,but also highly correlated with the data using the gravimetric method,indicating that theβ-ray method is not affected by soot particles under different industry conditions.
