China's sulfur dioxide and nitrogen oxides governance started very late, so far still in the exploratory stage, some power plant flue gas desulfurization denitration device most of Europe, the United States, Japan, the introduction of technology, or experimental, and equipment to deal with flue gas is very small, not yet ripe.

摘要我国对二氧化硫和氮氧化物的治理方面起步很晚，至今还处于摸索阶段，国内一些电厂的烟气脱硫脱硝装置大部分欧洲、美国、日本引进的技术，或者是试验性的，且设备处理的烟气量很小，还不成熟。

By using the water and electricity associated effect, a new method to remove SO2 and NO in flue gas, developed from the popularly studied methods at present, is mainly discussed in this paper and described in detail as following: A simplized model is built to describe the desulfuration and denitration process in gas phase by corona discharge plasma.

为找到新的更有效的脱除SO2 和NO 的方法，本文在现有的脱硫脱硝方法的基础上，选定了水-电协同脱除烟气中SO2和NO 作为研究的重点，具体内容如下：建立了描述电晕放电等离子体脱硫脱硝过程中气相反应的简化模型，并利用龙格-库塔法模拟了放电产生的HO。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
