| 摘 要： | 本文讨论了波长范围的选取对三刺激值计算精度的影响；简述了ＣＩＥ关于三刺激值计算的有关规定；介绍了波长范围截短后产生的最大误差的计算方法，并在实际样品大量测试计算的基础上，选出２２个有代表性样品的测试计算结果。从中可看出一般样品的误差量值以及外插法校正后的效果。

| Abstract: | For discussing the influence of the waveleugth range upon the calculating accuracy of tristimulus valus. We brief discribe CIE recommendations concerning the calculation of tristimulus values and introduce a algorithm for calculating the largest truncation error. According to the measurements and computations of a large number of color samples, selected 22 representative ones provided the results of the truncation error and provided the evidence for which the extrapolation could reduce obviously the tristimulus values error. |
