Superoxide dismutase (EC 1.15.1.1;SOD) is a metal-containing enzyme that widely exist in organisms. It catalyzes the dismutation of superoxide free radical and produces hydrogen peroxide and oxygen.It plays an important role in protecting the plasmalemma from the reactive oxygen species.A recombinant plasmid pPICZA-sodM18 was constructed and after its linearization was transferred into chromosome of Pichia pastoris GS115 by electroporation.

超氧化物歧化酶(Superoxide dismutase；EC 1.15.1.1；SOD)是广泛存在于生物体内的金属酶，是机体内唯一以超氧阴离子自由基(O_2~-)为底物的酶，它能专一地催化O_2~-的歧化反应，生成过氧化氢和氧气，能有效的抵御氧自由基和其他氧化物自由基对细胞质膜的毒性，对机体防御氧化损伤起着十分重要的作用。

The structure shown in the figure : The governing body received direct or roller drying cylinder, as the main components of the rotation; After finishing the outside of the sphere, Bottom Cover and soak spherical carbon graphite seal ring joint seal reliable seal friction deputy, Sealing ring in the spherical shell of its annular space sliding, in addition to oil-free bearings and with the close cooperation of Shell, Rotating connector so that the free support, and therefore do not require a high level of accuracy installed; Spherical seal ring wear, Spring means of pressure at any time in advance to receive compensation, compensation for the shell slowly moved backward, accessible through the tube outside the inscription on the line to observe the seals wear; When steam, Oil flows through the media or other spherical sealing ring and oil-free bearings, the formation of thin liquid film, sealing and lubrication, thereby reducing friction and wear, extending the service life.

其结构如图所示：外管体直接接到辊子或烘筒上，为主要的旋转部件；经过精加工的外管本球面、底盖和浸泡碳石墨球面密封环共同组成密封可靠的动密封磨擦副，球面密封环在其壳体内的环形空间中滑动，加之无油轴承与壳体的密切配合，使旋转接头自由支撑，故对装机精度要求不高；球面密封环磨损后，借助于弹簧的预压力随时得到补偿，补偿时壳体缓缓向后移动，并可通过外管体上的刻线观察到密封件的磨损程度；当蒸汽、油或其它介质流经球面密封环和无油轴承时，形成一层很薄的液膜，提供密封和润滑，从而减轻了摩擦和磨损，延长了使用寿命。

The properties of TCC with ATS were as good as the TCC with HTS, better that the requirement of standard GB8744-88 for semi-graphitic carbon block. As good as TCC with HTS in industrial cells, the TCC with ATS also reduces the sodium penetration to cathodic lining, no tear-off of the coating was found after starting up of the cells. As compared with reference cells, the operation of coating cells with ATS was also improved to keep good shape of cell chamber, reduce the formation of sludge on the cell bottom, and gain more uniform current distribution. The ohmic drop of TCC cell bottom was lessened by 11. 5mV. The current efficiency was increased by about 1. 48% in average. It was estimated that the TCC life could be 44 months. Obviously, the TCC with ATS could also improve the performance of industrial cells, save energy, and increase the cell life.

对常温固化涂层槽的考核表明，与高温固化涂层槽一样，阴极内衬对钠的吸收减少，钠渗透速度减缓，从而减小钠膨胀危害，减少了铝电解槽早期破损的几率；启动后，常温固化涂层不脱落，同样具有良好的粘接性能；与对比槽相比较，常温固化涂层槽正常生产后，阴极表面干净、光洁，无沉淀或结壳，炉膛规整，阴极、阳极电流分布均匀，炉底压降降低（平均降低11.5mV），电流效率提高（平均提高1.48％）；涂层在电解槽内存在的时间可达到44个月以上；常温固化涂层同样可以起到改善电解槽工作状态、节能降耗、延长槽寿命的作用。

One is a hierarchy of endogamous status groups –castes - constituted by rules of propriety and a division of labour among castes, a hierarchy from the lowest to the highest, the most polluted to the purest, in which aspiration to rise in the hierarchy can be realised by caste, or sub-caste mobility, through domination converted into caste, or by acquiring higher caste accomplishment and changing or disguising one's natal status.

一个是族内婚姻群体阶序——种姓制度——各种姓间要遵循等级适当原则和劳动等级分工。该阶序从最底等级到最高等级，最污浊等级到最纯洁等级。在该阶序中，等级上升的愿望可以通过种姓或亚种姓的改变而实现。改变种姓或亚种姓的方法有通过正式的皈依进入种姓，或者取得较高种姓的成就，以及改变或隐瞒其天生的等级地位。

The result of immobilization showed that hydrophile membranes were more advantageous than hydrophobe ones to act as immobilization carrier. Crosslinking organophosphorus hydrolase by glutaraldehyde on polyethersulfone membrane is a simple and practical immobilization method. An appropriate amount of bovine serum albumin and crosslinker is necessary to get a good result of immobilization. In the biodegradation of methyl-parathion through enzyme membrane reactor, the effect of immobilized enzyme amount, flow rate of peristaltic pump, pH of the feed, and the methyl-parathion concentration on biodegradation rate was studied. It was shown that the biodegradation rate increased with immobilized enzyme amount and substrate concentration. Biodegradation rate didn't increase when the folw rate of the peristaltic pump was larger than 7 ml/min.
