防腐蚀的

I plant the radiator using current advanced welding technology, in the process do not change the steel structure, the connection point of the solder joints using ultrasonic non-automatic laser welding, weld contact surface so that greater and more uniform, and no welding slag, to ensure welding safety, strengthened the combination of the Department of Welded Joints of alkali and acid mist erosion of professional skills, enhanced anti-corrosion products, while research and development of new technologies, new materials for new product development.

我厂散热器采用当前先进的焊接工艺，在加工过程中不改变钢的结构，连接点采用超声波无焊点的自动激光焊接，使焊缝接触面更大，更均匀，且无焊渣，确保了焊接的安全性，加强了焊口结合部的耐碱和酸薄雾侵蚀等专业技术，增强了产品的防腐蚀性能，同时不断的研发新技术，新材料用于新产品的开发。

When complete a deep and ultra-deep well casing program, especially a gas well, strength design, thread sealing design and anticorrosion design are needed to introduce. Meanwhile, many factors including external loadings, casing strength models selection, plastic rock creep stress, intermediate casing wear, temperature effect, thread air tight ability are necessarily considered.

认为对于深井超深井套管，尤其是气井必须引入强度设计、密封设计、防腐蚀设计，需要从外载的计算、强度模型的选择、塑性岩石蠕动引起的载荷、技术套管磨损、温度效应、螺纹的密封性以及套管本身强度的选择等方面进行研究。

Especially for the of concrete frame structure building and steel frame structure building without traditional brittle filler wall, using steel-mesh-cement-mortar plastering as inter insulating layer connected with the main structure to forming flexible composite wall can meet the requirement of saving 65% of energy for wall in the cold region and ensure the safety of the device installed on the opening to shield sunshine and facilitate its installation.

聚酯薄膜和聚丙烯酸酯乳液都是耐久性非常好的材料，可达到40年有效防腐期，有希望达到50年的有效防腐期，远远高于现在的钢材防腐蚀涂层十几年的寿命，在粘接强度满足使用要求条件下，及提高混凝土构件的柔性，对社会的可持续发展具有重要意义。

Herein through investigation on the collected CO2 corrosion data from different CO2-contained oil and gas fields, this study analyzed the serious damage and hazards on the gas production, summarized up the general rules of CO2 corrosion and its peculiarities at different areas. According to studies on phenomena, features, mechanism, and influencing factors on CO2 corrosion, this study put forward that a few effective countermeasures should be taken for anti-corrosion technology including injecting corrosion inhibitor, adopting stainless steel or bimetallic materials for the combination casing strings or well tubings.

为此，对我国几个不同类型含CO2油气田的现场的CO2腐蚀资料进行了调查、研究，分析了CO2腐蚀给天然气生产带来的严重危害性，总结出在不同类型油气田中CO2腐蚀的一般规律和不同区域CO2腐蚀的特殊性；在对CO2腐蚀的现象、特点、类型、机理以及腐蚀的影响因素研究的基础上，提出了含CO2气井防腐工艺技术应着重解决好含CO2气井的完井、生产管柱采用不锈钢或双金属复合油管、加注缓蚀剂等几种有效的防腐蚀措施。

Carving gravure of business card printing and membership card making production and offset business card printing and membership card making, and so on are very different, first of all the manuscripts submitted to approx 10 times, the perimeter line by hand is decisived on top of a piece of zinc tablet with a smaller machine to get an outside line back into the original large carved in a piece about an inch of eight brass, and copper strip it is some anticorrosive toppedwith films, because of copper strip is triggered from the perimeter line, so the rough body by hand for the film, when removed, and then use the medicine to the erosion of deep water, and proto-end knife with a magnifying glass and, thetolerant to the edge, sharp corners repaired, such as location on a layer of chrome, it's a printing plate.

雕刻凹版的制卡和会员卡制作制作与柯式制卡和会员卡制作等有很大的分别，首先把来稿放大约十倍，把外围线用手工刻划在一块锌片之上，再用一部缩细机械把外线缩回原大刻在一块约八份一寸的铜片上，而这件铜片上是涂有一些防腐蚀薄膜的，因为铜片只是勾上字的外围线，所以要用手工将粗身地上的薄膜刮去，然后用药水将印纹蚀深，最后仍要用放大镜及雕刻刀，耐性地将线边、尖角等位置修好，再镀上一层铬，这印版便大功告成。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
