The corrosion and the mechanism of corrosion resistance of steel products have been introduced in this paper,and the research on the corrosion resistance of the super-thin intumescent fire coatings for steel structures ,which are with both high fire performance and insulation and good corrosion resistance and with the resin of crylic acid as the substrate,is mainly included.

介绍了钢材的腐蚀及防腐机理，研究了以对丙烯酸树脂进行复合改性为基料，研制出的一种既具有高效防火隔热性能，又具有优异防腐蚀性能的超薄膨胀型钢结构防火涂料的防腐性能。

A review was given on the current state and development of intumescent fire retardant coatings for steel structure.

Shandong Jingbang Industries Limited Liability Company, established in May 2003 with a registered capital of 6 million yuan, administered Jingbang Steel Co., Ltd., Shandong Province and Shandong Province Jingbang Building Materials Co., Ltd., is a concentrated, large steel structure works Design, production, installation of steel structures for the integration of professional engineering company; company annual production and sales of steel structures and other insulation works centrifugal glass wool carpets, stable quality and reasonable price, by province and the surrounding Provincial and municipal customers praise.

山东靖邦实业有限责任公司，成立与2003年5月，注册资金600万人民币，下辖山东省靖邦钢结构有限公司和山东省靖邦建材有限公司，是一家集中型、大型钢结构工程的设计、制作、安装为一体的专业钢结构工程公司；公司常年生产、销售钢结构工程及其它保温隔热工程所需的离心玻璃棉毡，质量稳定，价格合理，深受本省及周边省市客户好评。

Aiming at the special deformation mechanism during the with tension rolling of H beam in universal pass, a three-dimensional continuous kinematically admissible velocity field is put forward for the first time, in which, the non-uniform distribution of longitudinal velocity in lateral direction and the special deformation mechanism of the web and flange joint deformation zone are taken into consideration.

针对H型钢在万能孔型中带张力轧制时特殊的变形机理，首次提出了考虑金属横向流动的三维、连续运动学许可速度场；速度场中考虑了纵向流动速度沿横向的不均匀分布以及腹板和翼缘交界变形区的特殊变形状态。

The furnace, U-beam separator, and superheater enclosures are constructed entirely of top-supported, gas-tight, all-welded membraned tube walls which do not require hot expansion joints.

炉膛、U型钢分离器，以及过热器的外壳由顶部支撑、气密、全焊接的膜式管墙构成，因此不需要膨胀节。

The research of this technology is successful, to raising H profiled bar be able to bear or endure await gender, corrosion resistance, be able to bear or endure microtherm concussion function has important sense.

该技术的探究成功，对于提高H型钢的耐候性、耐腐蚀性、耐低温冲击性能具有重要的意义。

Through analyzing cold-formed thin-walled C steel column by chosen section with different height and edge condition, we prove the element Shelll8l is appropriate to simulate monosymmetrical members.

通过对选定截面冷弯薄壁C型钢轴心受压柱的在不同柱高与边界条件下的有限元模拟分析，证实运用壳单元Shell181分析单轴对称构件的受力特性是合适的。

Our factory is a specialized enterprise which major in production stainless steel, stainless steel wire,Stainless steel round steel, Stainless steel flat steel, Stainless steel cold-drawing light bar, Stainless steel angle iron, Stainless steel square iron , Stainless steel hexagon bar;,Stainless steel cold-drawing section, Stainless steel wire, Stainless steel chain link, Stainless steel mesh belt, Stainless steel chain wheel, Stainless steel pressing part, rustless iron and special steel products .

本厂是专业生产不锈钢，不锈钢丝；不锈钢圆钢；不锈钢扁钢；不锈钢冷拉光元；不锈钢角钢；不锈钢方钢；不锈钢六角棒；不锈钢冷拉型钢；不锈钢丝绳；不锈钢链条；不锈钢网带；不锈钢链轮；不锈钢冲压件，不锈铁与特殊钢材的专业性企业。

Results of experiment and analysis show that open-web trussed steel reinforced concrete columns have relatively good behavior of ductility and energy dissipation.

试验结果表明：空腹析架式型钢混凝土框架柱具有良好的延性和耗能能力。

The findings of the research demonstrated the existence of "Group Effect" in the connections including more than one screw, which means that the assumption that the connection strength for a multiple screw connection is proportional to the number of screws in the connection, as the calculation method in Chinese current national standard Technical code of cold-formed thin-walled steel structures have based on, would result in an unconservative estimate for the shear capability of connections including more than one screw.

本文研究结果表明：自攻螺钉连接中存在&群体效应&，我国现行《冷弯薄壁型钢结构技术规范》中相关设计计算方法忽略群体效应，对含多颗螺钉的自攻螺钉连接偏于不安全。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
