介绍了一种光谱校正积分光度法及其在蓝光LED光通量测量中的应用，对测量中的各种不确定因素作了理论分析，并与单纯的分光光度法和积分光度法的不确定度作了比较，证明该方法可实现极高的测量精度。

For two continuous casting billets of typical stainless sheets (304 and 0Cr13), three positions including the edge, 1/2 and 1/4 along the thickness were spectroscopically analyzed through successive layer and multiple point modes. The uniformity of lumpish continuous casting billet sample was studied by statistical analysis and the major factors influencing the accuracy of spectral analysis were discussed.
