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。 -
In addition, super - short term strategies also earn significantly positive returns. nevertheless the contrarian strategies under long formation horizons and holding horizons ( beyond 36 weeks ) may yield significantly positive returns. we also find, considering markert factor ( market return, cross - sectional variance of equity returns ) and characteristic of individual stock ( trading volume, firm size, price, price / earnings, be / me ), there exist clearer and more significant patterns of profitability in momentum or contrarian strategies
具體而言，大體上以中短持有期的慣性策略（持有期4 ? 24周）有較顯著之利潤，超短期形成期的慣性策略在1 ? 12周的獲利性亦很顯著，而較長形成期（ 36周以上）與較長持有期搭配的反向策略則可能獲得顯著的正收益。 -
The curvatures of the curves between total formation conductivity c, and total water saturation swt, are greatly affected by formation matrix conductivity cma, while it is less affected by clay conductivity ccl. the curvatures of the curves between c, and swt are only affected by w, a factor number that is related to relative volume of water content in the formation, while is not much affected by the matrix factor number ma. when ct is kept to be constant, swt increases ash ma increases, and decreases as w increases
通過對該模型的影響因素分析，發現泥質分佈形式對模型計算的含水飽和度有很大影響；隨cma變化， ct與swt關系曲線的曲率發生變化；隨ccl變化， ct與swt關系曲線的曲率基本不變；只有或_ w變化， ct與swt關系曲線的曲率發生變化；只有_ （ ma ）變化， ct與swt關系曲線的曲率相近； ct一定， swt隨或_ （ ma ）增大而增大，隨_ w增大而減小。
