Color difference is an important factor to evaluate the quality of printing and packaging products. Based on the Munsell Renotation data, CMC(1:c) CIE94 and CIEDE2000 were analyzed using PF/3. The result showed that the performances of the three color difference formulae have little difference.

色差是评定印刷包装产品质量的一个重要参数，在孟塞尔新标数据集的基础上，用PF/3方法对CMC(1：c)、CIED94和CIEDE2000三个色差公式进行了对比分析，结果表明在该数据集下3个色差公式的性能相差不大。

Carbon source,nitrogen source,cultivation temperature,the initial pH of the culture medium,the speed of shaker are involved in the experiments,and the evaluation of retting is based on the residual gum content in retted flax roving.Then flax roving treated under the optimal conditions is compared with untreated roving in ingredient analysis,scanning electron microscope and infrared spectrum analysis.The result shows that the microbe treat...

用筛选出的一种真菌对亚麻粗纱生物处理的工艺进行了探讨，以残胶率作为评定标准，研究了碳源、氮源、温度、pH值、摇床转速对亚麻粗纱生物处理效果的影响，并在最佳工艺下对亚麻粗纱再处理，对处理后的粗纱进行成分分析、扫描电镜、红外光谱等测试，结果表明：亚麻粗纱的生物处理是可行的。
