建筑饰面材料不同方向反射光亮度测量误差研究

A Research on Measuring Error of the Building Facing Materials'Reflective Luminance Illuminated from Different Orientations

通过对建筑饰面材料不同方向反射光亮度测量数据的系统和偶然误差研究 ,得到不确定度和置信度的数值 ,其置信度在 95 4 5 %以上 ,证实了测量值的可靠性。

By means of systematic error analysis and accidental error analysis of the measuring data of the building facing materials'reflective luminance illuminated from Different Orientations,this paper works out the indeterminacy and the confidence.The confidence is more than 94^45% which proves the measuring data is reliable.
