| 摘 要： | 采用分光光度计对塑料白度进行测定,是精确度比较高的一种方法。通过测定样品的各个波长光谱反射率,同时选取特定的标准光源与CIE标准观察者光谱三刺激值,从而计算出样品颜色三刺激值。在此基础上采用Taube白度公式(CIE推荐)即可计算出样品白度。

| Abstract: | The whiteness of foamed PVC were measured with an UV-Vis spectrophotometer. This method is more precise than normal colorometer. The calculation is based on the measurement of reflectivity and the selection of CIE spectro three stimulating values. Taube formula recommended by CIE was used in this calculation. |
