A major problem encountered in the animal cell culture bioreactor design and scale-up is that the animal cells are susceptible to damage in the presence of mechanical agitation and/or gas sparging needed to supply sufficient oxygen and mixing to the cultures. Based on the analysis of the cell damage mechanisms, here the principle of the bioreactor design for suspended animal cell cultures has been developed.

The removal efficiency of VOCs by the air sparging process depends critically on the contact volume of the contaminated groundwater by the injected air, or the sweep efficiency.

气提法是藉著注入地下水层中的空气将溶於地下水及非饱和层中的挥发性有机污染物带出，因此空气在含水层之流动路径及接触污染物的排扫效率就成了影响气提法现场污染整治成效的重要因素。

With porous microcarrier cell culture, the macroporous structure allows growth of the cells inside the microcarriers, protecting them from potentially damaging effects of fluid flowing, mechanical agitating and gas sparging.

采用多孔微载体培养细胞，由于细胞生长在其内部，可为细胞创造良好的微环境，细胞生长不受流体流动、机械搅拌和气体喷射的影响。

The integration of the in-situ chemical oxidation, the air sparging and soil vapor extraction is an innovative technology. However, as the domestic remediation cases are concerned, the local contractors use gravitational injection to inject chemical oxidants in order to save cost.

现地化学氧化法整合空气曝气法及土壤气体抽取法系统为一项创新的技术，而国内现阶段之整治案例，厂商为节省成本考量化学氧化剂注入方式系以重力式注入为主。

Experimental results showed that gas sparging could increase permeate flux and improve the efficiency of fractionation during the ultrafiltraion of xylanases. The lower the liquid flow rate, or the higher transmembrane pressure, the more pronounced the enhancement in the ultrafiltration efficency.

结果发现，通入少量的空气即能显著改善溶剂透过率和分离因数，这种改善效果与操作条件相关，液相进料速度较低、操作压强较高时，气体鼓泡所产生的效果较为明显。

Solvents are normally degassed before pumping by sparging with helium, sonication or using on-line membrane/vacuum modules to avoid the creation of gas bubbles in the detector cell.

溶剂被抽之前，通常用氦气鼓泡，超声波或使用再线膜/真空组件来去除气体，以避免检测池中气泡的产生。

We suspect the reason that a high Ks was achieved with the combination of thermophiles and ultrasound irradiation is that the experiment was partial continuous and the air sparging mixer was not automated.

结果显示，经超音波震荡与高温消化确实可使污泥中微生物基质亲和力增加，使基质愈容易被分解。

Because soil vapor extraction technology and air sparging technology mainly depend on physical mechanisms, such as basic computation of fluid dynamics, the expected results are often obtained if one can control the required variables.

本论文主要针对国内已完成整治加油站污染场址，经由场址背景资料汇整与场址采用整治方式之适切性及其成效做探讨，分析几个影响整治成果之因素，包括采样位置、污染时间、地下水位等，进一步选定常见的土壤气体抽除法及空气注入法成功案例评析，而依据各场址整治流程发现，整治工法能否成功，掌握改善作业之关键点因素是最重要的部分，如场址特徵，污染物扩散情形、土壤质地，及是否适合现地整治等，由於土壤气体抽除法及空气注入法之整治方式，主要为物理性机制，牵涉到一些基本流体力学的计算，只要掌握足够之变数因子，利用推导方式，设置适合之整治井数量，通常应能获得预期之成效，但前提仍是现地场址的特性调查须完整，如此推导之结果才具有足够之可信度，由於国内整治计画及成果报告内容中，针对污染场址所施行工法的设计参数资料大多仅略述，仅将重点放在整治后采样之数据上，因此往往其整治成效在理论推导上较缺乏支持。

In order to simply the method, we further propose using magnetic stirring with weighted ring in stead of argon sparging; using air-circulated incubator in stead of water bath for better observation and sample collection; using centrifuging in stead of filtration for extract pretreatment; using one phase of simplified bioaccessibility extraction method instead of the two-phase method for a better estimate to the in-vivo method.

爲进一步简化试验方法，建议将开放式反应槽改为密闭式；使用可调速磁力搅拌及具载重环磁石，取代昂贵之氩气搅拌；将水浴温控改为气控式，以利试验观察与采样。此外，小肠相萃取不使用吸附剂，萃取液前处理利用高速离心取代压阻较高之过滤方式。本研究二阶段试验之生物有效性皆低估动物试验RBF，建议可将二阶段胃肠体外试验方法改为单相一阶段生物有效性萃取(simplified bioaccessibility extraction， SBET)试验方法。

We will see more and more activist government policies that distinguish economic activities according to the nationality of the actors.

我们将看到越来越多激进的政府政策，这些政策根据企业的国籍来区分经济活动。

If we can prove the independence of an axiomatic system, then we can guarantee the conciseness of this system, ie.

如果能够证明某个一阶谓词系统的独立性，那么就能够保证该系统的建立是精炼的，即没有任何一条公理或推理规则是多余的。
