查询词典 contamination

It is well recognized that people are the major source of contamination in an aseptic processing filling operation.

这是一个很好的认识：人是无菌灌装操作过程中的主要污染物。

Continental basalt ; island-arc or active continental margin basalt ; crustal or lithospheric contamination ; asthenosphere or plume

Moreover, the atomy economy increases; meanwhile, the environment effect decreases. This experiment need not consume sodium chloride to reduce the 4-chloro-2-nitrophenol solubility. The working procedure of hydrolysis may participate in reduction process without being liquid-solid separation; consequently there is no waste water to bring contamination.

将中间体4-氯-2-硝基苯酚钠(C6H3ClNO3Na)改为4-氯-2-硝基苯酚(C6H4ClNO3)的工艺，其原子利用率和环境因子有所提高；不需再加入食盐来降低4-氯-2-硝基苯酚在水中的溶解度；水解反应不需要进行固-液分离，直接进入还原工序，没有"三废"问题。

Compared to wet season, arsenic is difficult to mobile in dry season. Attenuation constant in dry season is 0.3082(1/km), but it is 0.0569(1/km)in wet season. If initial concentration of As was 500μg/L without other contamination source in down stream, arsenic would deceased to 50μg/L in down stream 7.5km in dry season but 40km in down stream 40km. As is dominate species in river running throμgh mining area.

砷在枯水期较丰水期难以迁移，通过计算得到，在枯水期砷的衰减系数K值为0.3082(1/km)，而在丰水期为0.0569(1/km)；在污染口浓度达到500μg/L时，下游没有其它的砷的污染源(或会影响砷衰减的其它污染源)时，枯水期砷会在下游7.5km之后浓度降到50μg/L，而丰水期则要在下游40km之后才能降到同样的值，所以在丰水期砷污染的影响的流域更广。

Background: The autograft preparation process for anterior cruciate ligament reconstruction has a potential for graft contamination.

背景：在前交叉韧带重建的自体移植物预备过程中，存在污染的可能。

In particular, Bacillus cereus contamination detection rate as high as 100%.

尤其是蜡样芽孢杆菌的污染检出率高达100%。

Furthermore, additional research on the value of time to positivity and quantity of growth for differentiating culture contamination from bacteremia is necessary.

另外，有必要进一步研究区分血培养污染菌的生长时间和数量。

In contrast, all of the positive controls (100%) in this group demonstrated obvious bacterial contamination.

与之相反的是，所有的阳性对照组均表现为显著的细菌污染。

Bacteriological contamination in the condensed water is reduced by constructing the apparatus from components that retard bacteria growth.

细菌污染，在冷凝水是减少了建设器具从组件延缓细菌生长。

You can also soak clothes and bed linen in disinfectant before washing them to reduce the risk of contamination.

您也可以泡衣服和床单，在消毒前的清洗他们，以减少污染的危险。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.
