The characteristic of this series leveler iS that it has adopted two national patent technologies:group driving plate levelling machine ZL200420001176.0 and axial decelerating motor leveler ZL200520007514.6.Each top roll is driven by a set of decelerating motor.and every two lower rolls are driven by a set of dynamic system,so that the line speed of each roll iS consistent with sheet metal speed of the contacting part,and it has solved the problems existing in traditional transmission system,such as friction between sheet metal and roll surface.and mechanical interference problem in the system And the working roll adopts spherical roller bearings which have little friction resistance.so this series leveler has such advantages as high levelIing quality,Iittle noise,low energy consumption and environmental protection.compared with traditional levelers.

该系列矫平机的特色之处在于：采用分组驱动板材矫正机(ZL200420001176.0)和一种轴装式减速电机矫平机(ZL200520007514.6)两种国家专利技术，每根上辊由一套减速电机驱动，每两根下辊由一套动力系统驱动，从而使各辊的线速度与所接触部位的板料速度相一致，消除了传统传动系统存在的板料与辊面之间的摩擦和传动系统内部的机械干涉问题，同时由于工作辊的轴承均采用轧机用调心辊子轴承，摩擦阻力小，因此，该系列矫平机与传统矫平机相比，矫平质量高、噪音小、能耗低、节能环保。

In fishing,the sliding cone blocks enter the fish cavity easily acted by a guide shoe and a guide cone,slide downward by its own weight,produce relative displacement to the guide rail slope,and the radial distance between its tooth face and the spear rod increases until it touches the inner wall of the fish cavity; while lifting the drilling string,the guide rail slope on the spear rod forces the sliding cone blocks to bite the inner wall of the tubing fished.

打捞时在引鞋和导锥的作用下滑牙块能够顺利进入鱼腔并依靠自重下滑，沿导轨外伸直至其齿面与鱼腔内壁接触；随后上提钻柱，矛杆上的导轨斜面迫使滑牙块咬紧被打捞油管内壁，当油管严重偏磨使一对滑牙块卡在磨穿位置时，另一对能有效卡在未磨损部位，同时外筒限制了油管外胀变形。

Lijiang city is situated in northwest Yunnan province. It is a beautiful city. There are the magnificent, snow-topped Yulong mountains, the boundless Jinsha River, and the original site of Lijiang Old Town, with its long history. Xuan Ke was born here in 1930, the son of a minister. His father was a broad-minded man, and had several foreign friends, which gave Xuan Ke an exposure to English in his youth. He later continued his English studies at a religious school, and in no time the clever lad was speaking fluent English.

解说：丽江市位於云南省部，是一个美丽的城市，这里有壮丽的玉龙雪山，气势磅薄的金沙江，还有历史悠远的丽江古城。1930年，宣科出生在丽江古城，他的父亲是个牧师，他思想开明，还结交了一些外国朋友，这使宣科在幼年时就有机会接触到英语，后来他进入丽江教会学校继续他的英语学习，天资聪明的宣科很快就能讲一口流利的英语了。

The small-grained spherical copper powder is large in the contact area with the steel base and binds sufficiently and firmly in the process of sintering.

小颗粒球形铜粉与钢基体接触面积大，烧结过程中结合充分、牢固，大颗粒球形铜粉与小颗粒球形铜粉烧结相容性好，结合牢靠，并且大颗粒铜粉之间的间隙大，螺旋铜钉层可进一步加大这个间隙，改性聚甲醛可以深埋在螺旋铜钉及大颗粒铜粉的间隙中，使改性聚甲醛工作更可靠。

With this method the copper plating graphite powder was made up in 50% copper content .The silver- copper plating graphite composite was prepared while the silver- copper-graphite composite and the silver-graphite composite were also made up together .The mechanical and electric characteristics of the three kinds of composites were tested and it was found that the copper plating graphite powder can only optimize the properties of the silver matrix composite under the high content of the graphite ,the conductivity and the mechanical property was improved and the material could take higher current in the same carbon content .At 20% carbon content, the resistivity of Ag-graphite composite was 1.67 times as high as that of silver- copper plating graphite composite, the resistivity of Ag-Cu-graphite composite was 3.23 times as high as that of silver- copper plating graphite composite. The bending strength of silver-copper plating graphite composite was 2.17 times as high as that of silver- copper-graphite composite, and the bending strength was 2.11 times as high as that of silver- copper-graphite composite. The wearability of silver- copper plating graphite composite was also enhanced greatly at high carbon content.

利用该方法制备了50%铜含量的镀铜石墨粉，然后进一步制备了一系列相同碳含量的银-石墨复合材料、银-铜-石墨复合材料、银-镀铜石墨复合材料，对三种材料的机械、电气性能进行了综合对比，发现在低碳含量时镀铜石墨粉不能改善复合材料的上述主要性能，而在中高碳含量时则能明显优化复合材料的整体性能，提高了复合材料的电导率，使复合材料在中高碳含量时既具有较高的耐磨性同时也能负载较大的电流，复合材料的机械性能也因镀铜石墨粉的加入而大幅提高，20%碳含量时，银-石墨复合材料的电阻率是银-镀铜石墨复合材料的1.67倍，银-铜-石墨复合材料的电阻率为银-镀铜石墨复合材料的3.23倍，银-镀铜石墨复合材料抗弯强度是银-铜-石墨复合材料的2.17倍，是银-石墨复合材料的2.11倍，同时，在实验给定的条件下，中高碳含量时银-镀铜石墨复合材料的机械磨损耐磨性和通电磨损耐磨性都得以显著提高，银-镀铜石墨复合材料在实验时的接触电压降也更为稳定。

Contact found in 80 works will impose upon space and the norm of thinking seems to exist faults and barriers, ahead of fashion conscious consumers continue to derive more imaginative ideas to make their work a kind of weightlessness a sense of unconscious, self-desire expansion and to meet the Gengrang has become such a vague sense of, when hidden, at times, a lot of 80, after describing himself as an artist is not weight of objects, flying freely in the air, floating, this subjective state of consciousness driven by the description of means that the objective mental states, disorders and emptiness, extreme inflation and a good self-concept of a serious departure from the idealism and sense of reality, greatly outstrips reality, a feeling based on fantasy or fantasy thinking.

在我们接触的作品中会无形中发现80后的思维空间与常态似乎存在着断层和隔阂，超前时尚的消费意识不断派生出更有想象力的观念使他们的作品有种无意识的失重感，自我欲望的膨胀和满足更让这样的意识变得虚无飘渺、时隐时现，很多80后艺术家将自己描述成没有重量的物体，在空中自由自在的飞行、飘浮，这种主观意识状态驱使下的描述，意味着客观精神状态的失常和空虚，极度膨胀和自我良好的唯心意识观严重背离了现实，凌驾于现实之上的感觉建立在空想或幻想的思维中。
