In this paper, aerobic digester was fed with anaerobically digested sludge, and its seed sludge was activated sludge.

好氧生物反应器的进料物是经厌氧作用的消化污泥，而其接种体是活性污泥。

Methods The presence and localization of the dilatant nasal mucosa capillaries in proband was determined by endoscope of nasal cavity; clinical diagnosis of HHT was established by obtaining the patient's bleeding history, family history, and observation of bleeding sites.

完善血常规、肝肾功能和胸片、腹部B超、血氧饱和度等检查；进行出凝血时间、血块回缩率、血小板聚集功能等检查；对与先证者有血缘关系的家系成员进行胸片、腹部B超、血氧饱和度检查，以排除和诊断HHT，绘制HHT遗传系谱图。

The result showed that, the effect of the synergistic reaction of alkyl-phenol-polyoxythylene ether phosphate dispersant TERSPERSE 4896, nonyl phenyl polyoxyethylene ether dispersant TERSPERSE 2210 and XG to suspension was different. Both the rheological curves were same presented as pseudoplastic fluid when they stored in R. T (18~25℃) for 10 days, but the rheological curve of suspension with the synergistic reaction of TERSPERSE 2210 and XG was changed to dilatant fluid when it stored in R.

结果表明，烷基酚聚氧乙烯磷酸酯类分散剂TERSPERSE 4896、壬基酚聚氧乙烯醚类分散剂TERSPERSE 2210与增粘剂黄原胶协同使用所得悬浮体系，室温(18~25℃)贮存10d仍表现出二者共同的流变特性，呈假塑性的流变曲线；但室温贮存150d后，含TERSPERSE 2210与黄原胶的悬浮体系的流变性质发生了明显变化，由假塑性流体向膨胀型流体转变。

The influences of the amount of 1,2-diaminoethane, temperature, molar ratio of epichlorohydrin and dimethylamine, and time on the viscosity and cationic degree of polyamine flocculants were investigated.

以环氧氯丙烷和二甲胺为原料，乙二胺为交联剂，制备有机阳离子聚合物，研究乙二胺加入量、反应温度、环氧氯丙烷和二甲胺的摩尔比、聚合时间等对聚合物粘度和阳离子度的影响。

A tunable Diode laser was used to probe gain spectra of a supersonic COIL.

用小型亚音速氧碘激光器做探测光源，逐点测量超音速氧碘激光器的小信号增益二维空间分布，最大增益为1.1×10〓cm〓。

For each temperature,the compositions of solvent mixture are 0,5,10,15,20,25 and 30% of dioxane.

每个温度有7个不同的二氧六圜和水的成分(0%，5%，10%，15%，20%，25%，30%的二氧六圜)，因此得到49个速度常数。

The circular dichroism spectra of soluble CSL in the presence of dioxane showed that dioxane made the αhelicity of the CSL increase.

CSL在二氧六环介质中的CD谱的变化表明：二氧六环使CSL分子中的α-螺旋含量有所增加。

Dioxane is a byproduct of a petrochemical process called ethyoxylation, which involves using ethylene oxide to process other chemicals in order to make them less harsh.

1，4二氧六环的副产品是一个石化过程被称为ethyoxylation ，其中包括利用环氧乙烷，其他化学品，以使它们显得温和。

In the study of by-product dioxane in polymerization reaction of EO,it is found that the effect of solvent is very small.And so do the catalyst BF_3-H_2O complex and catalyst H~+.

计算结果也解释了BF_3-H_2O催化环氧乙烷聚合产物分子量达到某一极限值后不再增加，消耗的单体都生成了二氧六环的原因。

It was also found that at experimental concentrations there was no regularity for the change of activity of copper salicylate encapsulated in negatively charged liposomes, and copper salicylate encapsulated in liposomes with more negative charges could promote the dismutation of superoxide anion free radicals, however, so could copper salicylate encapsulated in liposomes with fewer negative charges only in lower concentrations.

并发现在实验浓度范围内，负电性脂质体包裹的水杨酸铜，活性变化无规则，且荷负电量多的脂质体包裹的水杨酸铜促进超氧自由基的歧化，而荷负电量少的脂质体仅在低浓度区对超氧的歧化表现为促进作用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
