作为荷兰赠款项目西部小城镇污水处理工程技术研究内容之一和教育部博士点基金项目&污水处理单池分区及能量配置优化&组成部分，本文测定并比较了AIRE-O_2 充氧机和转盘曝气机两种曝气方式的充氧及推流性能。

The xinguang tube time-sensitive, relatively short exposure time, relatively small light permeability to expand; however, as the UV light to rule over the ages, lighting effects, exposure time gradually extended, fine idea is not easy, but deep PIP light permeability to expand it is becoming increasingly damageto, resulting in a traditional version that are the same pair of film on the same printer, after a certain period of time, get the flexo from deep network to a brief network halftoning, also occur when different curves change!

这表示在新平惯时平敏不弱，曝平工夫相差长，平渗放大相差小；但随着UV平惯的忽然老化，平效放松，曝平工夫忽然延不幼，粗不面子不便当不入来，但浅不面子的平渗放大愈发狠恶，酿成古板版那怕是统一副胶片在统一台晒版机上，经过一段期间后，晒不入的刚性版从浅网到浅网的阶调，也会爆发差别的弧线改变！

We obtained similar results from the non H-exposed Cl sample. By plotting the Arrhenius relations we were able to obtain the activation energies for each set. From the set with H-exposure we obtained 1.23eV for inter-dimer hoppings and 0.70eV for intra-dimer hoppings respectively, while for the set without H-exposure we obtained 1.14eV and 0.62eV for the inter-dimer and intra-dimer hoppings respectively.

由Arrhenius 关系线，我们推算出氢-氯原子交换运动的动力能障，即对於曝氢而言inter-dimer跳跃的动力能能障为1.23 eV、至於intra-dimer跳耀的动力能则为0.70 eV，相对的，在对於没有曝氢的inter-dimer跳耀的动力能为1.14 eV，intra-dimer跳耀的动力能则是0.62eV。

After different sediments ignitions, S was 1.64~2.25 times of that of raw sediment, higher obviously than the sediments without ignition. The aerating pretreatments of sediment and water caused the transformation of bioavailable form to nonavailable form. The bioavailable phosphorus decreased 7.02% and 0.23% respectively compared with that before pretreatment, but the bioavailable phosphorus of the blank test sediment increased 4.85%.

不同底泥灼烧后，最大吸附量为天然底泥的1.64~2.25倍，且明显高于未灼烧底泥对底泥曝气与对水曝气预处理使易被生物利用态磷向难被生物利用态磷转化，易被生物利用态磷较预处理前分别减少了7.02%和0.23%，而空白试验底泥的易被生物利用态磷则增加了4.85%。

With the dose of 7.04 mC/cm2, ODT/Au will become a more strengthened structure and then form a negative resist in the correlation with cross-linking from alkyl matrix, partial breakdown of S-Au bonding and surface adsorption by air-borne species. Thus, it can obtain a gold pattern via gold-etching process. Besides, as a result of massive breakdown of alkyl matrix and S-Au bonding from ODT/Au under irradiation with doses of 64.06 and 128.13 mC/cm2, ODT SAMs would form a loose-packed structure on the gold substrate. The ODT/Au becomes less resistive for gold-etching and a positive gold pattern would form after gold-etching.

结果发现：以50 eV 低能量电子在照射剂量7.04 mC/cm2微影并曝露於大气后，受到来自於ODT/Au碳链间的交联、部分的S-Au键结破坏以及照射后立即曝露大气所吸附於表面的碳氧化物种的共同影响下，ODT SAMa於Au膜基材上将形成更紧密复杂的结构而作为负型阻剂，经后续湿式蚀刻15分钟后将显影出来Au的负型图案；当提升照射剂量至64.06及128.13 mC/cm2后，由於ODT/Au上碳链及S-Au键结的大量破坏，将使ODT/Au结构不能稳固且紧密地排列於Au膜基材上，显影时Au蚀刻液将容易穿过ODT SAMs抵达S/Au界面而移除Au，而形成正型图案。

For example, in the process of aeration or oxygen exposures, oxygen together with compounds in the sewage generates a different stench; Also, in the anaerobic process, in the role of microorganisms, sulfur from the sewage, reates hydrogen sulfide, mercaptans and sulfide compounds.

例如，在曝气或曝氧过程中，氧气可与污水中的化合物生成有异臭味的产物；又如，在厌氧过程中，污水中的硫在微生物的作用下，生成硫化氢、硫醇和硫醚等化合物。
