中国精制漆研究——Ⅰ.透明精制漆漆酶活性的测定方法——薄膜-光度法 STUDY OF THE CHINESE REFINEMENT URUSHI Ⅰ. The determination, method of laccase activity of transparent refinement urushi——film-spectrophotometry 邓南圣 Den Nansheng Yu Congyan first-author 余从艳 本工作建立了测定精制漆漆酶活性的方法——薄膜-光度法。样品不需预处理,不需称量,用量少（30—50mg）,涂成膜直接测定。测定结果精密度好。实测八个样品,其相对标准偏差分别为4.80,3.60,3.14,3.30,5.37,4.18,4.78和4.13%。 In the present work a determination method of laccase activity of refinement urushi has established. The method is called film-spectrophotometry. Pre-treatment and weigh of the sample is unnecessary. Sample used is less（30-50mg）. Sample can be determined in the form of a film. The method is simple and rapid. Precision of determination results is good. Relative standard deviation of the determination results for 8 samples are 4.08, 3.60, 3.14, 3.30, 5.37, 4.18, 4.78 and 4.13% respectively. 1986-01-01 2021-04-01 1
