For the fermentation coupled with distillage recycle,every five days,the total backset distillage collected was directly used to mix the corn powder,and the experimental results revealed that the concentrations of ethanol,residual reductive sugar,inorganic phosphate and total solids in the broth were maintained s.

实验结果表明，在稀释速率0.05 h-1，废糟液全循环条件下，装置达到稳定状态后，乙醇、残还原糖、无机磷、无机氮、蛋白和总固型物浓度分别稳定在9.4%、26 g/L、11 g/L、3.36 g/L、0.136 g/L和85 g/L左右；乙醇浓度与对照组相差不大，但残还原糖、无机磷及总固形物在废糟液循环使用的初期出现积累，但随运行时间的延长而趋于稳定，说明对酵母生长和乙醇发酵没有产生明显影响。

The results showed that 1,5-naphthalene disulfonic acid could be degradated effectively by the catalytic supercritical wa...

结果表明，催化超临界水氧化技术能有效地降解1，5-萘二磺酸，COD去除率可达98%以上；随着反应温度的升高，停留时间的延长，COD去除率也提高；1，5-萘二磺酸在超临界水中催化氧化降解反应的级数对COD和氧气分别为0.89和0.28，活化能为56.8 kJ/mol。

In the absence of additional cross-linker, increasing molding temperature from 25 to 125℃significantly enhances crosslinking density of the three-dimensional proteinnetwork through disulphide bonding, leading to increase of tensile strength, Young\'smodulus and relaxation time.

未添加任何交联剂时，仅将模压温度从25℃升高到125℃，可提高蛋白质网络的二硫键交联密度，导致拉伸强度和杨氏模量增高、松弛时间延长。

Subcordiformis in Huanghai Sea near Dalian, it can be able to evolve H〓 photosynthetically. Comparing with Chlamydomonas reinhardtii in our lab, the H〓 productivity is same. By the elementary macro regulation of H〓 production with 2, 5-dibromo-3-methyl-6-isopropyl-p-benzoquinone , N, N'-dicyclohexylcarbodiimide , 3-(3, 4-dichlorophenyl)-1, 1-dimethylurea , sodium dithionate, sulfur-deprivation and cell immobilization, the results show that DCCD, immobilization and sulfur-deprivation has a positive effects on the H〓 production.

利用DCCD（质子泵抑制剂N，N'-dicyclohexylcarbodiimide）、DBMIB（光合电子传递抑制剂2，5-dibromo-3-methyl-6-isopropyl-p-benzoquinone）、DCMU[PSⅡ光合放氧抑制剂3-（3，4-dichlorophenyl）-1，1-dimethylurea]、连二亚硫酸钠、无硫调控及固定化扁藻等手段，对该扁藻产氢进行初步的宏观调控，发现DCCD的加入、扁藻的固定化和无硫调控对产氢均有正效应，其中无硫调控使扁藻产氢时间延长，总产氢量提高了近10倍。

Ankle Foot Orthosis is usually applied for stroke patients to prevent foot drop during swing phase, and provides some range of ankle dorsiflexion after mid stance phase on walking. These conditions cause cyclic tensile and compression force on the AFO, and result in breaking or tearing of AFO after several weeks or months usage. Therefore, it is important for therapists to know what geometric modification of AFO can prolong its usage. The purpose of this study was to develop a motion simulator for observing the effect of simulated heel strike impact and foot dorsiflexion on the AFO. The geometry of motion simulator was designed similar to human leg.

足踝副木经常被使用在中风患者下肢以避免走摆荡期发生垂足现象，同时，副木於站期中期后也能提供些许的踝关节背曲角，此一况导致副木遭受循环的张与挤压，常於星期或个月的使用后，导致副木疲断或撕，因此，让治师解副木的几何外型改设计能延长使用时间是很重要的，也因此，本研究目的为设计一评估副木疲破坏的运动模拟器，用以观察副木遭受模拟的脚跟著地冲击与足踝跖曲与背曲弯折对副木的效应。

This work might lead to develop many better methods or means of preventing and controlling dysenteric diarrhea.To elucidate the role of H-NS protein in bacterial physiology, the hns gene insertion and deletion mutants were constructed with RecA and Red recombination system. Then, growth curve and invasion ability of wild strain and deletion mutant were studied.

为了更深入的了解hns基因在细菌生命活动中所起的作用，我们首先利用RecA重组系统构建了痢疾杆菌2457T hns基因的插入突变体；随后，对基于Red重组系统的痢疾杆菌2457T缺失突变体的构建方法进行了摸索并成功地敲除了hns、hdeA、hdeB、yhiE和yhiF 5个基因，研究表明延长同源臂的长度可以明显提高同源重组的效率，缩短构建缺失突变体所需的时间。

The removal abilities for naphthalene by Eichhornia crassipes solms increased with temperature and exposing time under sunlight respectively.

在一定范围内，凤眼莲对萘水溶液的净化效率分别随气温的升高及太阳光照时间的延长而升高。

Eichhornia crassipes solms not only could survive wider range of pH (5～12), furthermore it could make the pH towards neutral.

在净化萘水溶液的过程中，凤眼莲不仅能够适应较广的pH（5～12），且能随净化时间的延长使pH逐渐趋于中性。

It was shown that, the flow pattern in the EMPT was more complex than that in traditional one, that is, in the column chamber, the short circuit flow from the outlet nozzle of the ladle was depressed by the rotating molten steel, and horizontal recurrent flow appeared in rectangular chamber, which prolonged the average staying time of the molten steel, then reduced the volume fraction of inactive area in EMPT.

结果显示，电磁净化中间包的流场比传统中间包的流场复杂：在圆形腔中，旋转运动抑制了大包水口至矩形腔的短路流，而在矩形腔中形成水平环流，从而延长钢液在中间包的平均停留时间，死区减小，电磁净化中间包的上述流场结构及传输行为对钢液中的非金属夹杂物去除非常有利。

Causted entirely by fees encharge they says unless the fees reflect actual costs, services would be have to cut back wating time for applicans would increase.

他们表示除非服务收费能反映实际成本，不然他们只能减少服务开支，而移民申请者的等待时间也会因此延长。
