查询词典 DO

Nitrosobacteria was selectively cultivated on the biofilm and short-cut nitrification was achieved in 4 weeks by controlling the following conditions as HRT=1 d, DO=0.5—1.0 mg·L-1, pH of about 7.5, T =30℃ and no sludge recycle.

结果表明，在控制HRT=1 d、温度30℃、DO=0.5～1.0 mg·L-1、pH=7.5左右、无污泥回流等条件下，经过4周的运行，成功地选择培养出亚硝化型生物膜，实现了短程硝化。

According to the above study result, the diversity of microorganisms population in the SUFR system is complex and the bio-community formed in the SUFR system is stable. The close relations between abundance of bacteria and nutrients were found. The correlation between heterotrophic bacteria and COD was 0.949. The correlation between organic phosphate bacteria and TP was 0.815. The correlation between nitrosobacteria and NH3-N was 0.909. The correlation between disnitrifier bacteria and TN was 0.653. These inneglectable great factors effecting on phosphorus-uptake and phosphorus-release of phosphorus accumulating organisms are the influent COD、the concentration of DO、the sludge retention time、the temperature. The diversity of organic phosphate bacteria population in the SUFR reactor was complex and there is no phosphate bacteria taking the absolute superiority in quantity. The near-native pure culture method powerfully complement the traditional pure culture technique and enrich culture technique. The sludgy bioactivity is very good in whole SUFR reactor. By the quality of being biochemistry, the anaerobic phase is higher than anoxic phase and the anoxic phase is higher than aerobic phase of SUFR.

通过以上试验内容研究发现，SUFR 系统中的微型动物种群较多，微生物生态系统稳定；系统中微生物的数量与营养盐的含量密切相关，其中总异养菌与COD的相关系数r 为0.949，有机磷细菌与TP 的相关系数r 为0.815，亚硝化菌与NH4+-N的相关系数r 为0.909，反硝化菌的数量和TN 的相关系数r 为0.653；污水生物除磷工艺中进水COD 的浓度、DO 浓度、泥龄的长短、温度都是影响聚磷菌释磷及吸磷效果的不可忽视的因素；SUFR 系统中的磷细菌呈现种群多样化的趋势，没有占绝对优势数量的磷细菌；微孔滤膜近自然培养法是对传统纯培养技术和富集培养技术的有力补充；整个SUFR 反应器系统中污泥的生物活性很好，就可生化性来讲，厌氧反应器大于缺氧反应器大于好氧反应器；按照动力学方程式求出的细胞生长动力学特征值和SUFR 脱氮除磷系统工艺的实测值结果基本吻合。

Both DO and ORP are used as fuzzy control parameters of SBR1 aerobic duration, which can maintain heterotrophs for organics removal and Nitrosomonas in different reactors and make TSSBR system operate stably and reliably.

将DO和ORP联合作为SBR1阶段好氧反应时间的模糊控制参数，可使去除有机物的异养菌和硝化菌存在于不同的反应器内，保证两段SBR系统长期稳定运行。

Again, Mikyo Dorje said, in Tuton Gyatsa, that there are eight things to be given up by the monks, like meat, alcohol, weapons and things like that—I can't remember all of them—because this is what has been described in Do Palmo Che.

此外，米觉多杰在他的着作《修行百颂》（《Tuton Gyatsa》）中提到过，有八样东西是出家人必须舍弃的，像是酒、肉、武器这一些，我记不起来每一样是什么了，但在《华严经》（《Do Palmo Che》）内也是有这样的记述的。

Aquatic plants were soaked in two purifying-tanks to investigate the effects of illumination intensity and aeration on diurnal variations of Chla,SP,POD of Pontederia cordata and pH,DO,COD,NH+4-N,TP of water from purifying-tanks when treating the malodorous river water at seven different times,another blank purifying-tank was set as a control. Comparative studies and correlation analysis of these different indicators were carried out to improve the plants working efficiency and provide scientific basis for optimal operation of plant purifying-tanks.

测定了曝气和非曝气的2个植物净化槽在1 d中7个不同时间点的出水水质理化指标(pH、DO、COD、NH+4-N、TP)及植物叶片的叶绿素、可溶性蛋白含量及过氧化物酶活性，另设空白槽为对照；试验目的是研究各指标的日变化情况及相互关系，为提高梭鱼草净化黑臭河水的处理效率及其植物净化槽的合理优化运行提供科学依据。

It is important to realize that DO-178B/ED-12B not only states that dead code "should be removed": Section 6.4.4.3c continues with the statement that "an analysis performed to assess the effect and the need for reverification."

由此可见，死代码处理包括两件事，一是消除，二是分析，必要时还要做第三件事——重新验证。虽然标题里说&深入理解&，但这只是一种愿望，文章内容未必有深度，或许还有错误。敬请DO-178B加油站网友指正。

The results show a remarkable change in the chemical properties of rainfall after passing through the forest canopies. There is an observed decrease in pH and DO, obvious increase in TURB and TDS, and different degrees of increase in other chemical elements.

结果表明：大气降水经过林冠层后，其水化学特征发生了明显变化，pH和DO降低，TURB和TDS明显增加，化学元素含量均不同程度增加。

When studying simultaneous nitrification and denitrification in membranebioreactor,it was foud that the concentration of DO was a key factor and the influence of C/N,pH value and temperature were unconspicuous.

在研究同步硝化反硝化作用时发现，C／N、pH值和温度对同步硝化反硝化作用无影响，DO是影响系统同步硝化反硝化的关键因素。

Loop-control parameters shall be available inside the do-loop for words that use or change these parameters, words such as I , J , LEAVE and UNLOOP .

回圈控制参数必须在 do-loop 中可被用来改变这些参数的词存取，像是 I ， J ， LEAVE 和 UNLOOP 。

The need for a small pavilion at the Vila do Conde's museum's garden, where children and adults can have a rest and stop for some time during a visit to the museum, was the ideal starting point for exploring this idea of multiplication.

该项目是应Vila do Conde博物馆花园的需求而建，这里需要一个为儿童和游人准备的可休息和停留的空间，因此设计师设计了这个多功能亭。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
