-
Rufifacies, peak 16 ( unknown ) and 25 ( 11 -, 13 -, 15 - methyl - hentriacontane ) for b. peregrina and peak 3 ( unknown ), 4 ( tricosene ) and 23 ( unknown ) for p. crassipalpis. additionally, the models were developed respectively to determine the larval age of different flies accurately. 2 temperature effects of time - associated characteristic in cuticular hydrocarbons of aldrichina grahami larva highly significant correlation were observed between the relative abundance of some larval cuticular hydrocarbons associated with gas chromatographic peaks and the chronological age of al
2溫度對巨尾阿麗蠅幼蟲表皮碳氫化合物組成時間特徵的影響及日齡推斷模型的建立巨尾阿麗蠅幼蟲表皮碳氫化合物組份色譜峰，即p30 （二十五烯a ） 、 p33 （正二十五烷） 、 p48 （二十七烯a ） 、 p49 （二十七烯b ）和p79 （正三十一烷）含量與幼蟲日齡呈極顯著相關，且在不同恆溫（ 16 、 20 、 24和28 ）下的變化趨勢基本一致。 -
A. niger m - l which was screened in our laboratory produced a strongly a - transglucosidase. in this paper, studies on the fermentation conditions, purification and characterization of a - transglucosidase and its necessary groups was carried out in this dissertation. the main reports were as following : the fermentation conditions in shaking flasks were investigated by the method of single - factor analysis, the suitable main medium was achieved : which contained 4 % a, 2 % b and 1 % g ; the a. niger m - l was inoculated into 100ml medium in flask, shaking in 33 c at 140r / min for four days, with initial ph6. 5 and 6 % inocula volume ; adding 0. 1 mmol / l methyl a - d - glucopyranoside had inductive effect on enzyme formation, the a - transglucosidase activity amounted to 296. 05u / ml
本研究以黑麴黴m - 1為出發菌株，對其-葡萄糖轉苷酶的產酶影響因素、純化、酶學性質以及必需基團進行系統的研究，結果如下：通過對影響黑麴黴m - 1產-葡萄糖轉苷酶的單因素分析，得液態發酵生產-葡萄糖轉苷酶的最適產酶條件為： 4 a ， 2 b和1 g ；在33 ，起始ph值為6 . 5 ，轉速為140r min ，接種量為6 ，裝液量100ml條件下，發酵4 . 0d ，酶活力達296 . 05u ml ，添加0 . 1mmol l的酶作用底物甲基- - d -葡萄糖苷對產酶的誘導作用最大。 -

The contact angle for water of the film which prepared according to above conditions is 4 ? ( 2 ) b plus voltage is 1. 2kv ; sputtering time is 80min ; the target parameters are : 100 % anatase tio2, the thickness is 6. 5mm, the diameter is 53. 5mm, the quality is 24. 99g and the density is 1. 71g / cm3 ; anode current is imax. the constant of reaction kinetics of the film which prepared according to above conditions for degrading methyl orange is 0. 0192
Fe20 ;的摩爾含量為0 . 5 %時光催化活性最好;而在fezo3的摩爾含量為0 . 05一0 . 1 %時，獲得了具有超親水性能的復合薄膜;但fezo3 / tio :的疊層膜及復合疊層膜的光催化活性及親水性能均不理想，主要原因是fezo3的存在具有光生載流子復合中心的作用。
