查询词典 acidification

When the system run at a low temperature, the biogas production and COD removal rate in UASB reactor went down, but acidification did not occur. The performance of SBR was not influenced greatly by low temperature.

开发了三阶段两相厌氧工艺即酸化、内电解、厌氧产甲烷的工艺处理皂素废水。从理论上分析了该工艺处理黄姜皂素废水的机理和优势。在实验条件相同时，改变内电解在工艺中的位置进行间歇式厌氧处理，测得2种厌氧工艺的处理效果。实验结果表明内电解在两相厌氧中间CODC r的去除率要优于内电解在酸化前

The soil environment of solar greenhouse deteriorate with the growing ages increased and this causes the obstacle matters in soil of succession planting cucumber, mainly perform as soil physicochemical properties worsening, soil hypo-salinization, soil acidification.

The experiment researched the effect of different catch crops on cucumber yield and soil physicochemical properties.

Uses the advanced water-oil separation design technology, the equipment has dynamically filters, the automatic slime function, therefore effectively alleviates the oil the acidification, the inhibited oil acid value elevates with the pollution, this equipment not only saves gas and oil, also the very great degree enhanced the product quality and product outward appearance unattractiveness.

采用先进的油水分离设计技术，设备具有动态过滤、自动沉渣的功能，因此有效缓解油的酸化、抑制油的酸价升高和浑浊，本设备不仅节油，也很大程度提高了产品的品质和产品外观的漂亮。

Four uncropped soils in subtropical tea producing area were applied in soil column experiments to study the influence of urea and fallen tea leaves on soil acidification.

用亚热带茶区的4种未垦荒地土壤作土柱模拟，研究了重施尿素和表覆茶树落叶对土壤酸化的影响。

Hyphae, loaded with CTC under pH 6. 8 condition and then grown in pH 8. 0 medium for a little while to destroy the apical acidification, could gave very diffuse fluorescence images of CTC membrame bound Ca〓 and vermiform fluorescence spots due to mitochondrias under pH 6. 8 no longer were clearly distinquished, which implied that besides mitochondrias, other cellular organelles with Ca〓 also were stained with CTC. Thus mitochondrias are not the only one intracellular Ca〓 storage, endoplasmic reticulums and Golgi bodies in the same zone may be also the Ca〓 storages. But the extreme apical zone under 2μm of the growing hyphal tip was still almost devoid of stain under pH 8. 0.The CTC fluorescence was concentrated in the subapic zone beyond about 2μm from the tip and then gradually became lower behind about 40μm from the tip. These results did not support the hypothesis which suggested that the cell wall vesicles in the extreme apical zone were intracellular Ca〓 storages.

将菌丝在pH6.8条件下负载CTC，再置于pH8.0培养介质中短暂生长一会儿以消散菌丝顶端的酸化区域，则CTC膜结合Ca〓呈现弥散的荧光影像，在pH 6.8培养条件下显示的蠕虫状的线粒体荧光斑点不再能够清晰辨认，说明除了线粒体之外，还有其它含Ca〓细胞器，也被CTC染色，线粒体并不是细胞内唯一Ca〓库，还可能包括内质网、高尔基体等细胞器，但菌丝最顶端2μm以前的细胞壁泡囊区域不能被染色，最大荧光强度仍位于菌丝顶端2μm以后区域，约45μm以后荧光变弱，实验结果不支持细胞壁泡囊为菌丝胞内Ca〓库的假设。

Professor Wootton says the most troubling finding is the speed of acidification, with the pH level dropping at a much greater rate than was previously thought.

伍顿教授称，最恼人的发现是酸化的速度，PH值以前所未有的速度下降。酸化速度要比以前预测的模型快10到20倍。
