At its liquid fermentation culture process , the most appropriate carbon source is glucose and white sugar , while the most appropriate nitrogen source is ammonium tartrate . the results also indicate that cg grows best between ph value 6 . 0 - 8 . 0 , in which its growth period is about 15 days , and the best inoculating amount and the liquid capacity are respectively 10 - 15 % and 100 - 200ml . all these results will provide the theory bases for the reproducing of cenococcum geophilum 其液体培养最适碳源为葡萄糖、市售白糖；最适氮源为酒石酸铵。在ph值为6 . 0 - 8 . 0之间生长最快，其生长周期为15d左右，最佳接种量和装液量分别为10 - 15 %和100 - 150ml 。以上试验结果为土生空团菌的扩大繁殖提供了理论依据。
It shows that the injection quantity and the difference of temperature distribute as a parabola which is at the same load , and the minimum of the parabola corresponds to the optimum quantity of injection ( g ) . under the condition that the quantity of injected mass , the air speed and the heat quantity is respectively g , v and q , the research demonstrates that the pentium iv chip ' s temperature variation can be controlled under 40c and work normally when the wind speed overpass 1 . 5m / s and the power dissipation of the chip is 60w . otherwise this paper calculates the flooding limit of thermosiphon with several different methods 对其充灌量、散热量、电子元件( cpu模拟芯片)表面与环境温度之差及通风、流速的影响进行了系统的测试，发现充液量与温差的关系在负荷不变时呈抛物线分布，其极小值点对应的充液量是最佳充液量g 。在充液量为g时，对风速v 、散热量q进行的研究表明，当风速超过1 . 5m / s后，奔腾芯片在60w发热条件下芯片温度小于40 ，能满足长期正常工作。
The xylanase activity of the mutant kept stable after 10 generations . after orthogonal designing experiment , the optimum fermentation conditions of a . niger j 506 were obtained , which is as followed : concentration of the major carbon resource 4 % , ratio between bran and corncob 5 : 5 , concentration of glucose 0 . 1 % , concentration of ammonium oxalate as supplemental nitrogen resource 2 . 0 % , the initial ph of liquid medium 5 . 0 , 100ml / 250ml flask 经过正交试验设计，得出突变株a . nigerj506产木聚糖酶最佳的工艺条件为：主碳源浓度4 、麸皮与玉米芯的比例为5 ： 5 、辅加碳源葡萄糖的浓度是0 . 1 、辅加氮源草酸铵的浓度是2 . 0 ，培养基初始ph为5 . 0 ， 250ml三角瓶的装液量为100ml 。
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 本研究以黑曲霉m - 1为出发菌株，对其-葡萄糖转苷酶的产酶影响因素、纯化、酶学性质以及必需基团进行系统的研究，结果如下：通过对影响黑曲霉m - 1产-葡萄糖转苷酶的单因素分析，得液态发酵生产-葡萄糖转苷酶的最适产酶条件为： 4 a ， 2 b和1 g ；在33 ，起始ph值为6 . 5 ，转速为140r min ，接种量为6 ，装液量100ml条件下，发酵4 . 0d ，酶活力达296 . 05u ml ，添加0 . 1mmol l的酶作用底物甲基- - d -葡萄糖苷对产酶的诱导作用最大。
This type of dryer was fitful for liquid drying in concurrent , counter - current or mixed air - flow . the dryer can produce powders , granules , hollow spherical particles and agglomerates products . the spraying capacity and particle size were changed by altering the parts assembled in the nozzle 压力喷雾干燥装置其雾化器的结构适用易调，可通过改变喷嘴的内部结构得到所需要的喷液量和雾滴尺寸，目前该型式干燥机已推广应用于食品、化工、医药、建材、环保等行业。
