This experiment passing to grope for the carbon source constitutes of the culture medium and using t. reesei rut c - 30 induced the expression of # - mannanase ( # - 1, 4 - mannan mannohydrolase ec 3. 2. 1. 78 ). in this experiment i put the constant carbon source ( lactose and locust bean gum ) in the foundation culture medium ( mandels nourishment liquid ) of t. reesei rut c - 30, then proceeded the variable carbon source ( dragon spruce fiber, com rush pith fiber, wheat straw fiber, wheat straw xylan, corn rush pith xylan, dragon spruce mannan ) to single factor, double factor, three factor, four factor and five factor orthogonal experiment. 1 determined the activity of p - mannanase using locost bean gum as substract by the 3, 5 - dinitosalicylic acid method, and observed the growing situation of the gernic at the end i selected the directions for the inducement expression of the # ? mannanase from trichoderma reesei rut - c30 that contained the dragon spruce fiber, wheat straw xylan, dragon spruce mannan
在里氏木霉rutc - 30的基礎培養基（ mandels營養液）中加入固定碳源乳糖和槐豆膠，然後將可變碳源（雲杉纖維、玉米芯纖維、麥桿纖維、麥桿木聚糖、玉米芯木聚糖、雲杉甘露聚糖）進行單因子、雙因子、三因子、四因子、五因子的里氏木霉rutc - 30正交培養實驗，並以槐豆膠為底物用3 ， 5二硝基水楊酸法測定培養液中?甘露聚糖酶的活力。從而確定了酶活最高且菌體生長良好的含雲杉纖維、麥桿木聚糖和雲杉甘露聚糖的誘導培養基為最佳培養基，用該培養基培養的里氏木霉（ t . reesei ） rutc - 30使其轉錄的-甘露聚糖酶（ - 1 ， 4 - mannanmannohydrolaseec3 . 2 . 1 . 78 ） mrna量能夠滿足rt - pcr的要求。Filament winding machine is the key device which uses continuous fibre reinforced plastics to wind produce, its primary function is through which continuous fibre ( such as glass, aramid, carbon fibres and wire ) or fabric is wound on the mandrel surface on which produce is shaped according to needed pattern laws by special mechanical moves and controls
纖維纏繞機是用連續纖維增強塑料來纏繞製品的關鍵設備，其首要功能是通過特定的機械運動和控制，將浸漬過樹脂膠液的連續纖維帶（如玻璃纖維、碳纖維、芳綸纖維、金屬絲等）或布帶，按照所要求的線型規律排布在制品成型的芯模表面上。5 have a better recovery. the flux - transmembrane pressure curves of several kinds of pu composite hollow fiber membranes differed completely from non - deformation membranes, deviated from the linear relation obviously. this strongly indicated that, due to pu characteristics, such as good elasticity and strong recovery, pu - sio2 composite hollow fiber membranes have a comparatively good pressure - responsivity
通過調整紡絲液濃度、 sio _ 2含量、中空芯液流量、紡絲溫度、凝固浴溫度等參數，紡制出5種較為理想的壓力響應性pu復合中空纖維膜，其中，含有20和25 sio _ 2的pu復合中空纖維膜孔徑增加和孔徑回復最為理想。
