The results show that catholic reduction of pyrolusite can be conducted, but the reduction rate is low. The effects of temperature to pyrolusite reduction on the cathode are remarkable. The exchange current density increases with the increase of temperature. The presence of irons is favorable to reduce pyrolusite.

结果表明软锰矿粒可以在阴极上还原，但所占比例较少，温度对软锰矿影响量大，软锰矿在石墨阴极还原的交换电流密度随温度的升高而增大，阴极极化的传递系数很小，添加铁离子有利于软锰矿的还原。

But how will the computer + the human brain in this intelligent combination of dual-core functions, when the computer system failures as a result of the virus and slow down or even crash, most people can only wait anxiously for the experts, or home computer to be painstakingly maintenance stations for maintenance, because the traditional way to deal with this problem again when the need to use the CD-ROM system (often because the driver would also like to find lost disk driver), a number of computers equipped with the "one-click restore" feature or the current popular technologies only GHOST users can restore your computer to your computer at all times or do the factory GHOST time, and after they were unable to retrieve data, and in the time to do the reduction is due to the use of conventional disk copy, the whole is a long time.

但如何将电脑+人脑这智能的双核功能结合在一起，当计算机由于系统故障、感染病毒而变慢甚至死机时，大多数人只能焦急地等待专家上门或费尽周折将电脑送到维修站进行维修，由于传统方式处理这种问题时需要使用光盘重做系统（常常会因为驱动盘丢失还要找驱动程序），许多电脑配备的"一键还原"功能或目前流行的GHOST技术仅仅可以将用户电脑还原到电脑出厂时刻或做GHOST时刻状态，之后的数据它们是无法找回的，而且在做这些还原的时候由于采用的是常规的磁盘拷贝技术，整个时间也是比较长的。

Taking Shewanella and Geobacter as examples, this paper reviewed three kinds of possible mechanisms of microbial enzyme-catalyzed dissimilatory Fe reduction and its molecular regulation, i.e., direct contact between microbial cell and Fe oxides, siderrophores, and electron shuttling compounds. Many membrane-bound cytochrome proteins are involved in the dissimilatory Fe reduction, forming a complicated regulation network.

以希瓦氏菌和地杆菌为例，本文综述了3种异化Fe还原的酶促反应机制及其分子调控机理：异化Fe还原菌与Fe氧化物直接接触机制、电子穿梭体的作用机制、铁载体作用机制，多种膜蛋白特别是多血红素的细胞色素蛋白参与微生物的异化Fe还原过程，并形成复杂的调控网络。

The direct electroreduction of nitrite requires large overpotential on most electrode surfaces, however, various transition-metal complexes were proved to be good catalysts for nitrite reduction.

NO〓〓的直接电还原需要很高的过电位，但各种各样的金属配合物被证明是NO〓〓电还原的良好催化剂，而我们在实验中惊奇地发现一系列饱和未取代的和稀土取代的杂多化合物对NO〓〓还原产生良好的催化作用。

The ratios of k~1 and k~2 varied within the range of 4.24～133, which showed that the control step for oxidation of CO over REFeO~3 was the reoxidation step of reduced catalyst.

催化剂用CO还原的速率常数k~1比还原了的催化化剂用O~2再氧化速率常数k~2要大， k~1/k~2值在4.22～133之间，这说明在REFeO~3上CO氧化的控制步骤为还原催化剂的再氧化。

Thus, SRB were likely to reduce sulfates to sulfides simultaneously with petroleum oxidization, and directly or indirectly reduce hexavalent uranium U to tetravalent uranium U to precipitate pitchblende.

于是，利用烃类作为生存的碳源，硫酸盐还原菌将硫酸盐还原的同时，直接或间接地把六价铀U还原成四价铀U，导致沥青铀矿形成。

The basic data obtained from the experimental research were calculated and disposed with computer and concluded an important principle of Li〓O by silicon thermoreduction. The factors affected the reduction such as temperature, pressure and time were dicribed by methematical equations. The relation ships of reduction rate with temperature, pressure and time were directly expressed by three-dimension figures. The relating mathematical equations described the process derived from research were proved to be coincided with the practice. Therefore, the obtained results were accurate and reliable and of important value.

运用计算机对试验研究得到的基本数据进行计算和处理，得到了氧化锂硅热还原的重要规律；用数学方程描述了温度、压力和时间还原的影响；用三维立体图直观地表现了温度、压力和时间〓与还原率的关系；研究得到的描述过程的有关数学方程，经验证与实际相符，因此得到的结果准确可靠。

Carbonyl reductase is a monomeric oxidoreductase that catalyzes the NADPHdependant reduction of a variety of quinones, ketones, and aldehydes. It is widely distributed in the cytoplasm of various tissues of mammalian and non-mammalian species, and is involved in detoxification, physical regulation, as well as in drug metabolism.

羰基还原酶是一类依赖于辅酶NADPH催化各种醌、酮和醛等物质还原的单体氧化还原酶，它们广泛分布于哺乳动物和非哺乳动物各种组织的细胞质中，具有解毒、生理调节和药物代谢等重要功能。

It was also pointed out that azo dye reduction occurred mainly under anaerobic condition. Different electron donor resulted in different decolourization rate.

指出厌氧偶氮还原是偶氮染料还原的主要形式，电子供体不同脱色效率不同。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
