摘　　要：提出了采用反射光谱测量纸浆卡伯值的新方法。就硫酸盐纸浆浓度对纸浆反射光谱的影响进行了研究。结果表明: 在指定波段内纸浆的光反射率受到硫酸盐纸浆水分含量(纸浆浓度)的影响, 随着纸浆水分的增加, 纸浆的光反射率下降, 在长波长处的光反射率降幅大于短波长处; 使用该方法时为了有良好的测量分辨率,硫酸盐纸浆浓度应大于2%。A newmethod for the measurement of the kappa number of Kraft pulp with reflecting spectrum is presented.The influence of kraft pulp consistency on the reflecting spectrum was studied in detail.It was found that the light reflecting ratio at a given wavelength range would decrease with the increase of moisture content of kraft pulp and the decrease would be greater at the longer wavelength.The kraft pulp consistency should be higher than2%in order to achieve a good measuring resolution of the reflecting spectrum.
