查询词典 ozone layer

The effects of electroplated Ni layer and electroless plated Ni-P layer on the diffusion behavior in Sn-Ag/Cu solder joint were studied. The results by EPMA analysis showed that the electroless plated Ni-P layer acted as a good diffusion barrier between Sn-Ag solder and Cu substrate. However, the electroplated Ni layer can not hinder the inter-diffusion and reaction between molten Sn-Ag solder and Cu substrate when reflowing, and there was a layer of IMC (Cu6Sn5) at interface of Sn-Ag/C u solder joint.

摘 要：研究了电镀Ni层和化学镀Ni-P合金层对Sn-Ag/Cu焊点扩散行为的影响，电子探针分析表明：化学镀Ni-P合金层能很好地阻止Sn-Ag/Cu焊点在焊接过程中的Cu，Sn互扩散和相互反应；而电镀Ni层则不能阻止Sn-Ag/Cu焊点在焊接过程中的Cu，Sn互扩散和相互反应，界面反应产物仍以Cu6Sn5为主。

Ozone oxidation is a efficient degradation method, but excessive ozone is not enough for the acenaphthene mineralization.

臭氧氧化法可以对其有效的降解，但是过量的臭氧也难以实现对苊的矿化，在苊浓度下降的同时将生成中间产物。

Due to ozone can cause upper respiratory tract inflammation, injury terminal bronchiole epithelial cilia, thus weakening the defense of the upper respiratory tract, so long-term exposure to a certain concentration of ozone is also easy to secondary upper respiratory tract infection.

由于臭氧能引起上呼吸道炎症、损伤终末细支气管上皮纤毛，从而削弱了上呼吸道的防御功能，因此长期接触一定浓度的臭氧还易于继发上呼吸道感染。

This paper introduces development and application of ozone biological activated carbon process and compared ozone biological activated carbon process with other similar process.

本文介绍了臭氧生物活性炭工艺的发展及应用状况，并将臭氧生物活性炭工艺与其它相似工艺进行比较。

0MgL^(-1) of ozone with 11 min exposure caused complete inactivation of young Chironomid larvae in filtrated water in the dynamic experiment. 0.8mgL^(-1) of ozone combined with GAC treatment was able to entirely eliminate Chironomid larvae with low activity.

动态试验中，臭氧投加量1.0mgL^(-1)，接触11min，臭氧对滤后水中的低龄期摇蚊幼虫可以达到100%灭活率；投加量0.8mgL^(-1)，臭氧－活性炭工艺的协同作用可以完全去除水中生物活性减低的摇蚊幼虫。

Ozone significantly enhanced the chlorobenzene removal rate of the biofilter. When the inlet ozone concentration was between 60~120 mg·m-3, the removal rate was more than 90%.

臭氧明显促进了生物过滤塔的氯苯去除性能，当进口臭氧浓度在60~120 mg·m-3时，氯苯平均去除率可由70%提高到90％以上。

Residual ozone disassociation is another problem that affects the application of ozone technology.

剩余臭氧分解是影响臭氧技术应用的另一个难题。
