Comparing it with the standard electrode potential of nitric acid,the reason of dissolution of HgS in aqua regia was quantitatively revealed,and this is that the high concentration of chloride ions reduces the reduction potential of sulfur in HgS,thus raising the reducing power of HgS rather than that the oxidizing power.

根据热力学平衡原理和设计的可逆电池反应，由 E~0Hg~(2++S/HgS数据，计算了 E~0HgCl_4~(2++S/HgS+4Cl~-数值，将其与 HNO_3的标准电极电位比较，定量地揭示了 HgS 溶于王水的原因在于该溶液中高浓度 Cl~-离子降低了 HgS 中硫的还原电位，从而提高了 HgS 的还原性所致，并非王水的氧化性比 HNO_3的更强。

A good home theatre system must be made to handle a lot of volume,resolve dialogue appropriately,reveal all other sound-track information and recreate realistically dynamic information without breaking up.The Dul'cets meet all these criteria,with an additional bonus-they can be used in audio-only applications,covering smoothly the audible frequency range.

The results showed that nitrogen oxide was strongly deoxidized to nitrogen by iron; Petroleum coke char and CO could promote the heterogeneous reaction of Fe and NO, deoxidize iron oxides, and prolong the active time of iron; while limestone had little effect on the heterogeneous reaction.

结果表明：Fe对NO有很强的还原作用；石油焦焦炭和CO对Fe与NO之间的多相反应具有很强的促进作用，可还原Fe的氧化物，延长Fe的作用时间；而石灰石对Fe与NO之间的多相反应几乎没有作用。

Results All the NQs can activate the calcium release channel to some entent and induce Ca2+ transportation.The modulations of 1,4 NQ,1,2 NQ,1,4 NQ2S and 1,2 N are biphasic and depend on their concentrations.The mechanism of gating modulation depends on oxidation and reduction of NQ.The by-products of NQ during oxidation and reduction do not interact with RyR.

结果 所有NQ都不同程度地激活钙通道引起钙流释放；1，4NQ、1，2NQ、1，2NQ、1，4NQ 2S和1，2NQ4S对RyR的调节表现出强烈的浓度依赖性的双相作用性；NQ通过氧化还原作用调控RyR的门控机制；NQ在氧化还原循环中产生的超氧等伴生物没有参与RyR的相互作用。

In thepreparation of nickel sulfides, nanocrystalline NiS〓 was prepared by solvent-thermaltechnology. By adding a reductive atmosphere in the system, hexagonal phase NiS,which is a metaphase and stable at high temperature, was formed. TEM shows that theparticles are in nanorod shape.

在甲苯中合成了球形的NiS〓纳米粉，并通过还原气氛的调节制备出NiS亚稳相的纳米棒(1000x15nm)，通过前驱物的改变，我们在还原性气氛中还制备出Ni〓S〓纳米粉；同时我们在实验中还发现溶剂对产物的形貌有很大的影响，在乙二胺中作溶剂，分别得到立方形CoS〓和NiS〓及FeS〓纳米棒。

On the NiO/SiO〓 catalyst prepared by IM, the main hydrogenation product of MA was SA, the activity and selectivity were almost no relation with the nickel content and nickel species 3. Summarizing the characterization and activity evaluation of the catalysts, we concluded: On nickel based catalyst, when NiO was crystallite, and the Ni〓 that was prepared by reducing, hydrogenation of the MA could lead to SA but not to γ-BL; when NiO was cluster and had a properly interaction with the support, the Ni〓 prepared by reducing, could hydrogenate MA to SA then to γ-BL. When NiO cluster and crystallite were both existed on the catalyst, the hydrogenation products were mixture of SA and γ-BL, and the amounts of SA and γ-BL were related with the ratio of cluster and crystallite.

综合催化剂的表征和活性评价得出：当镍基催化剂上氧化镍以结晶态存在，经氢还原后的零价镍可使顺丁烯二酸酐加氢得到丁二酸酐，丁二酸酐难以进一步加氢为γ-丁内酯；当镍基催化剂上氧化镍以簇团形式存在，与载体之间有适当的相互作用时，经氢还原后的零价镍可使顺丁烯二酸酐加氢得到的丁二酸酐进一步加氢为γ-丁内酯；若催化剂上氧化镍既有结晶态又有簇团形式时，随二者含量比例不同而得到丁二酸酐和γ-丁内酯的混合物。

This article mainly explains the safety principium of infectant factors in waste water vented by the paper making industry in China. Through the study on the experiment in open country and indoors with soil pole, indicating that it is a complicated process of biochemical degradation to form a layer, which has a biochemical capability to process COD degradation in polluted water from paper making industry.

综述我国造纸业污水中的污染因子危及地下水水质安全的机理，通过对野外试验和室内土柱试验的过程及结果进行分析研究，表明在包气带中形成一个以生物化学作用为主的生化层在造纸污水中COD降解是一个复杂的生物化学降解过程；生化层在天然状态下形成，由生物氧化带和生物氧化还原带形成，其形成过程具有明显的阶段性；只有当生物氧化还原带形成后，生化层才发育成熟，具备对COD降解的生化能力；生化层空间分布，仅局限在污水池、渠底部包气带中有垂向渗流的部分。

BST16 was also proved to encode gene of PSII lOkD protein by protein prosite and conserve domain analysis. The protein encoded by BST16 contained a conserve domain PsbR of PSII lOkD protein from 48 to 140 and its carboxy terminal had an ADH_SHORT prosite of Short-chain dehydrogenases/reductases family signature from 94 to 122, which showed the protein encoded by BST16 would be a reductases.

对该基因可读框架编码的蛋白进行功能位点和结构功能域的分析，同样证明了该基因为PSⅡ 10kD蛋白编码基因，其氨基酸摘要序列 48刁位含有一个保守的光合系统＊ 10kD蛋白结构域 PSbR，在蛋白的猿基端有一个保守的短链脱氢酶／还原酶家族特征序列ADHSHORT（Short－chain dehydrogenases／reductases family signature），位于94－122位，说明了该蛋白可能具有还原酶活性。

The amount ofethylene release by shoot apex and root showed no difference between iron-deficient treatment and control plants above before the appearance ofrelatively high reductase activity,which indicated that ethylene may not playa direct role in regulation of root ferric reductase activity,and the inhibitionof which by〓and〓may be caused by other reasons.

缺铁处理植株茎尖和根系乙烯释放量的测定结果显示，三种植物中，缺铁与对照植株的茎尖及根系所释放的乙烯可能不直接参与缺铁根系还原酶的调控，〓和〓对缺铁根系〓还原酶活性的抑制可能是其它原因所致。

Reductionists of whatever stripe are accustomed to arrive at surprising and far-reaching claims about the conditions for various phenomena: in holding that a given phenomenon reduces to such-and-such configuration of circumstances, they thereby portray those circumstances as necessary for that phenomenon.

各种还原论者习惯于获得关于各种现象的令人惊讶的、深远的主张：一个给予的现象，还原到如此这般环境构成，因此他们描绘这些环境作为现象的必要条件。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
