According to the structure and property of feather fibre fabric and the sizing ingredients,choosing the biological catalyst-enzyme which has high catalysis efficiency and undivided reactivity,to desize the feather fibre fabric ,the paste would be removed quickly and efficiently.

在羽毛纤维织物结构性能基础上，结合织物上所含浆料的组成，选择催化效率高、反应专一的生物催化剂酶对羽毛纤维织物进行退浆处理，可以快速、高效退除织物上的浆料，同时酶退浆时反应条件温和，不需要高温、高压、强酸、强碱的作用条件；采用超声波对羽毛纤维织物进行退浆可以缩短处理时间、降低处理温度，减少药剂用量，而处理效果优于常规法退浆。

The growth rate and enzyme activities significantly decreased when dikaryotic hypha ofPleurotus ostreatus were irradiated with γ-rays and subsequently treated with either caffeineor Na2-EDTA in comparison with γ-rays treatment alone. The inhibition effect of treatmentwith either caffeine or Na2-EDTA before irradiation was more obvious than that after irradi-ation. Treatment with either caffeine or Na_2-EDTA could cause biological damages on hyphawhen the concentrations of caffeine and Na_2-EDTA were up to 0.5 and 1.0mg/ml respective-ly.

侧耳双核菌丝经γ射线辐照后用咖啡因或Na＿2－EDTA处理，其生长速度和漆酶及多酚氧化酶活性较单一γ射线辐照明显降低，使辐射损伤加剧；辐照前用咖啡因和Na＿2－EDTA处理，抑制辐射损伤修复的效果优于辐照后处理；咖啡因和Na＿2－EDTA浓度分别达到0.5和1.0mg／mL后，单独处理侧耳菌丝会直接引起生理损伤。

Simultaneously, the total extractible myoglobin decreased and the proportion of metmyoglobin increased significantly when the pressure above 400MPa. Beef discoloration after pressure processing may result from oxidation of ferrous myoglobin to ferric metmyoglobin, globin denaturation and structural changes. At 40℃, the changes of beef color was similar to that of room temperature's. When the temperature rise to 60℃, most of muscle proteins denatured, a small quantity of native myoglobin could not affect the color of beef significantly. Therefore, protein denaturation was attributed to the main cause of discoloration in beef muscle after pressurization at 60℃.

压力处理导致色泽变化的直接原因可能是由于二价铁的肌红蛋白氧化成三价铁的高铁肌红蛋白、球蛋白的变性及结构的变化所致。40℃时的压力处理，色泽的变化规律与室温下相似，只是色泽变化的程度更为剧烈，蛋白质变性在色泽变化中起到的作用逐渐加强。60℃下的压力处理，绝大部分蛋白质发生变性，少量未变性的肌红蛋白对色泽不会产生明显的影响，此温度的压力处理，蛋白质变性是造成肌肉失去红色的主要原因。

G.E.Hubb root is from 0.20mm to 0.50mm, and 95% roots, diameter is thinner than 0.40mm. The total surface areas of roots is 10139.68cm^2, and the surface areas of roots is about 2 to 3 times to soil surface areas in the surface layer. Enlacing sod concretion to soil profile of Eulaliopsis binata G.E. Hubb root and the gigantic adsorption to soil grains of root surface are the mechanism why Eulaliopsis binata G.E.
