中国已有5000年的文明发展史,中国文化是世界最古老的文化之一,而且是世界上唯一的长期延续没有中断的文化。中国文化之所以具有如此强大的生命力,主要由其本身所固有的内在结构和基本素质所决定。中国文化的结构是“多元一体”的,“多元”是指它早期由多种文化融合而成,后来又接纳了各少数民族文化,且对外来文化具有极强的包容性,从而形成了一种“多元”文化兼容并包的格局;“一体”指多元文化熔铸为一个整体,形成了有着共同的价值观念和鲜明特色的中华民族文化。中国文化“多元一体”的结构造就了它自信宽容的素质,中国文化以我为主,不断吸收外来文化,在吐故纳新中获得了生命的活力。面临当今世界的挑战,饱经风霜的中国文化从容应对,在自我改造和改造世界中展示自己的文化魅力,并永葆青春。

科学就是探求真理。在探求真理的过程中,人们对客观规律的认识要经过艰苦曲折的过程。常常有这样的情形:由于研究的角度不同,掌握资料的差异,认识方法的不同,就会出现“横看成岭侧成峰,远近高低各不同”的情况,以至引起学术上的争论。因此,有作为的科学工作者都把反对的意见看作对自己的莫大的帮助,把对自己的批评当作最珍贵的友谊。正如歌德所说,“我们赞同的东西使我们处之泰然,我们反对的东西才使我们的思想获得丰产。”这都是因为,赞同的意见未必正确,反对的意见未必错误。退一步说,即使错误的反对意见,对自己的科学研究也是很有好处的。

科学研究的方法只是人类思维中必要的工作方式的表现,正是通过这种方式,人类对一切现象进行逻辑推理,并做出精确的解释。科学家的思维活动与普通人的思维活动之间并无实质的区别,其区别有如面包师或者肉匠用普通磅秤称量他们的物品,而化学家则用天平和精确/细致分级的砝码来进行难度很大和复杂深入的分析一样。并不是因为在前一种情况下的磅秤与后一种情况下的天平在构造原理或工作方式上有何不同,只是因为天平是更为精密的仪器,与磅秤比较起来,其称量结果自然要精确得多。如果给你举一些非常熟悉的例子,或许你会理解得更清楚。你会多次听说过科学家们是运用归纳法和演绎法工作,而且,在某种意义上,他们运用这些思维方式从自然界中总结出一些自然规则,然后运用特殊的技巧,在这些自然规则的基础上建立自己的理论。

A convection-conduction model for analysis of the freeze-thaw conditions in the surrounding rock wall of a tunnel in permafrost regions Abstract Based on the analyses of fundamental meteorological and hydrogeological conditions at the site of a tunnel in the cold regions, a combined convection-conduction model for air flow in the tunnel and temperature field in the surrounding has been constructed. Using the model, the air temperature distribution in the Xiluoqi No. 2 Tunnel has been simulated numerically. The simulated results are in agreement with the data observed. Then, based on the in situ conditions of sir temperature, atmospheric pressure, wind force, hydrogeology and engineering geology, the air-temperature relationship between the temperature on the surface of the tunnel wall and the air temperature at the entry and exit of the tunnel has been obtained, and the freeze-thaw conditions at the Dabanshan Tunnel which is now under construction is predicted. Keywords: tunnel in cold regions, convective heat exchange and conduction, freeze-thaw. A number of highway and railway tunnels have been constructed in the permafrost regions and their neighboring areas in China. Since the hydrological and thermal conditions changed after a tunnel was excavated,the surrounding wall rock materials often froze, the frost heaving caused damage to the liner layers and seeping water froze into ice diamonds,which seriously interfered with the communication and transportation. Similar problems of the freezing damage in the tunnels also appeared in other countries like Russia, Norway and Japan .Hence it is urgent to predict the freeze-thaw conditions in the surrounding rock materials and provide a basis for the design,construction and

中国的对外贸易外文翻译及原文

外文翻译 原文 Foreign T rade o f China Material Source:W anfang Database Author:Hitomi Iizaka 1.Introduction On December11,2001,China officially joined the World T rade Organization(WTO)and be c a me its143rd member.China’s presence in the worl d economy will continue to grow and deepen.The foreign trade sector plays an important andmultifaceted role in China’s economic development.At the same time, China’s expanded role in the world economy is beneficial t o all its trading partners. Regions that trade with China benefit from cheaper and mor e varieties of imported consumer goods,raw materials and intermediate products.China is also a large and growing export market.While the entry of any major trading nation in the global trading system can create a process of adjustment,the o u t c o me is fundamentally a win-win situation.In this p aper we would like t o provide a survey of the various institutions,laws and characteristics of China’s trade.Among some of the findings, we can highlight thefollowing: ?In2001,total trade to gross domestic pr oduct(GDP)ratio in China is44% ?In2001,47%of Chinese trade is processed trade1 ?In2001,51%of Chinese trade is conduct ed by foreign firms in China2 ?In2001,36%of Chinese exports originate from Gu an gdon g province ?In2001,39%of China’s exports go through Hong Kong to be re-exported elsewhere 2.Evolution of China’s Trade Regime Equally remarkable are the changes in the commodity composition of China’s exports and imports.Table2a shows China’s annu al export volumes of primary goods and manufactured goods over time.In1980,primary goods accounted for 50.3%of China’s exports and manufactured goods accounted for49.7%.Although the share of primary good declines slightly during the first half of1980’s,it remains at50.6%in1985.Since then,exports of manufactured goods have grown at a much

Thronson Unbenownst to most Americans, the United States is presently under thirty presidentially declared states of emergency. They confer vast powers on the Executive Branch, including the ability to financially incapacitate any person or organization in the United States, seize control of the nation’s communications infrastructure, mobilize military forces, expand the permissible size of the military without congressional authorization, and extend tours of duty without consent from service personnel. Declared states of emergency may also activate Presidential Emergency Action Documents and other continuity-of-government procedures, which confer powers on the President—such as the unilateral suspension of habeas corpus—that appear fundamentally opposed to the American constitutional order.

提高塔式复合人工湿地处理农村生活污水的 脱氮效率1 摘要: 努力保护水源,尤其是在乡镇地区的饮用水源,是中国污水处理当前面临的主要问题。氮元素在水体富营养化和对水生物的潜在毒害方面的重要作用,目前废水脱氮已成为首要关注的焦点。人工湿地作为一种小型的,处理费用较低的方法被用于处理乡镇生活污水。比起活性炭在脱氮方面显示出的广阔前景,人工湿地系统由于溶解氧的缺乏而在脱氮方面存在一定的制约。为了提高脱氮效率,一种新型三阶段塔式混合湿地结构----人工湿地(thcw)应运而生。它的第一部分和第三部分是水平流矩形湿地结构,第二部分分三层,呈圆形,呈紊流状态。塔式结构中水流由顶层进入第二层及底层,形成瀑布溢流,因此水中溶解氧浓度增加,从而提高了硝化反应效率,反硝化效率也由于有另外的有机物的加入而得到了改善,增加反硝化速率的另一个原因是直接通过旁路进入第二部分的废水中带入的足量有机物。常绿植物池柏(Taxodium ascendens),经济作物蔺草(Schoenoplectus trigueter),野茭白(Zizania aquatica),有装饰性的多花植物睡莲(Nymphaea tetragona),香蒲(Typha angustifolia)被种植在湿地中。该系统对总悬浮物、化学需氧量、氨氮、总氮和总磷的去除率分别为89%、85%、83%、83% 和64%。高水力负荷和低水力负荷(16 cm/d 和32 cm/d)对于塔式复合人工湿地结构的性能没有显著的影响。通过硝化活性和硝化速率的测定,发现硝化和反硝化是湿地脱氮的主要机理。塔式复合人工湿地结构同样具有观赏的价值。 关键词: 人工湿地;硝化作用;反硝化作用;生活污水;脱氮;硝化细菌;反硝化细菌 1. 前言 对于提高水源水质的广泛需求,尤其是提高饮用水水源水质的需求是目前废水深度处理的技术发展指向。在中国的乡镇地区,生活污水是直接排入湖泊、河流、土壤、海洋等水源中。这些缺乏处理的污水排放对于很多水库、湖泊不能达到水质标准是有责任的。许多位于中国的乡镇地区的社区缺乏足够的生活污水处理设备。由于山区地形、人口分散、经济基础差等原因,废水的收集和处理是很成问题的。由于资源短缺,经济欠发达地区所采取的废水处理技术必须低价高效,并且要便于施用,能量输入及维护费用较低,而且要保证出水能达标。建造在城市中基于活性污泥床的废水集中处理厂,对于小乡镇缺乏经济适用性,主要是由于污水收集结构的建造费用高。 1Ecological Engineering,Fen xia ,Ying Li。

预测高速公路建设项目最终的预算和时间 摘要 目的——本文的目的是开发模型来预测公路建设项目施工阶段最后的预算和持续的时间。 设计——测算收集告诉公路建设项目,在发展预测模型之前找出影响项目最终的预算和时间,研究内容是基于人工神经网络(ANN)的原理。与预测结果提出的方法进行比较,其精度从当前方法基于挣值。 结果——根据影响因素最后提出了预算和时间,基于人工神经网络的应用原理方法获得的预测结果比当前基于挣值法得到的结果更准确和稳定。 研究局限性/意义——因素影响最终的预算和时间可能不同,如果应用于其他国家,由于该项目数据收集的都是泰国的预测模型,因此,必须重新考虑更好的结果。 实际意义——这项研究为用于高速公路建设项目经理来预测项目最终的预算和时间提供了一个有用的工具,可为结果提供早期预算和进度延误的警告。 创意/价值——用ANN模型来预测最后的预算和时间的高速公路建设项目,开发利用项目数据反映出持续的和季节性周期数据, 在施工阶段可以提供更好的预测结果。 关键词:神经网、建筑业、预测、道路、泰国 文章类型:案例研究 前言 一个建设工程项普遍的目的是为了在时间和在预算内满足既定的质量要求和其他规格。为了实现这个目标,大量的工作在施工过程的管理必须提供且不能没有计划地做成本控制系统。一个控制系统定期收集实际成本和进度数据,然后对比与计划的时间表来衡量工作进展是否提前或落后时间表和强调潜在的问题(泰克兹,1993)。成本和时间是两个关键参数,在建设项目管理和相关参数的研究中扮演着重要的角色,不断提供适当的方法和

工具,使施工经理有效处理一个项目,以实现其在前期建设和在施工阶段的目标。在施工阶段,一个常见的问题要求各方参与一个项目,尤其是一个所有者,最终项目的预算到底是多少?或什么时候该项目能被完成? 在跟踪和控制一个建设项目时,预测项目的性能是非常必要的。目前已经提出了几种方法,如基于挣值技术、模糊逻辑、社会判断理论和神经网络。将挣值法视为一个确定的方法,其一般假设,无论是性能效率可达至报告日期保持不变,或整个项目其余部分将计划超出申报日期(克里斯坦森,1992;弗莱明和坎普曼,2000 ;阿萨班尼,1999;维卡尔等人,2000)。然而,挣值法的基本概念在研究确定潜在的进度延误、成本和进度的差异成本超支的地区。吉布利(1985)利用平均每个成本帐户执行工作的实际成本,也称作单位收入的成本,其标准差来预测项目完工成本。各成本帐户每月的进度是一个平均平稳过程标准偏差,显示预测模型的可靠性,然而,接受的单位成本收益在每个报告期在变化。埃尔丁和休斯(1992)和阿萨班尼(1999)利用分解组成成本的结构来提高预测精度。迪克曼和Al-Tabtabai(1992)基于社会判断理论提出了一个方法,该方法在预测未来的基础上的一组线索,源于人的判断而不是从纯粹的数学算法。有经验的项目经理要求基于社会判断理论方法的使用得到满意的结果。Moselhi等人(2006)应用“模糊逻辑”来预测潜在的成本超支和对建设工程项目的进度延迟。该方法的结果在评估特定时间状态的项目和评价该项目的利润效率有作用。这有助于工程人员所完成的项目时间限制和监控项目预算。Kaastra和博伊德(1996)开发的“人工神经网络”,此网络作为一种有效的预测工具,可以利用过去“模式识别”工作和显示各种影响因素的关系,然后预测未来的发展趋势。罗威等人(2006)开发的成本回归模型能在项目的早期阶段估计建筑成本。总共有41个潜在的独立变量被确定,但只有四个变量:总建筑面积,持续时间,机械设备,和打桩,是线性成本的关键驱动因素,因为它们出现在所有的模型中。模型提出了进一步的洞察了施工成本和预测变量的各种关系。从模型得到的估计结果可以提供早期阶段的造价咨询(威廉姆斯(2003))——最终竞标利用回归模型预测的建设项目成本。 人工神经网络已被广泛用在不同的施工功能中,如估价、计划和产能预测。神经网络建设是Moselhi等人(1991)指出,由Hegazy(1998)开发了一个模型,该模型考虑了项目的外在特征,估计加拿大的公路建设成本: ·项目类型 ·项目范围

204/JOURNAL OF BRIDGE ENGINEERING/AUGUST1999

JOURNAL OF BRIDGE ENGINEERING /AUGUST 1999/205 ends.The stress state in each cylindrical strip was determined from the total potential energy of a nonlinear arch model using the Rayleigh-Ritz method. It was emphasized that the membrane stresses in the com-pression region of the curved models were less than those predicted by linear theory and that there was an accompanying increase in ?ange resultant force.The maximum web bending stress was shown to occur at 0.20h from the compression ?ange for the simple support stiffness condition and 0.24h for the ?xed condition,where h is the height of the analytical panel.It was noted that 0.20h would be the optimum position for longitudinal stiffeners in curved girders,which is the same as for straight girders based on stability requirements.From the ?xed condition cases it was determined that there was no signi?cant change in the membrane stresses (from free to ?xed)but that there was a signi?cant effect on the web bend-ing stresses.Numerical results were generated for the reduc-tion in effective moment required to produce initial yield in the ?anges based on curvature and web slenderness for a panel aspect ratio of 1.0and a web-to-?ange area ratio of 2.0.From the results,a maximum reduction of about 13%was noted for a /R =0.167and about 8%for a /R =0.10(h /t w =150),both of which would correspond to extreme curvature,where a is the length of the analytical panel (modeling the distance be-tween transverse stiffeners)and R is the radius of curvature.To apply the parametric results to developing design criteria for practical curved girders,the de?ections and web bending stresses that would occur for girders with a curvature corre-sponding to the initial imperfection out-of-?atness limit of D /120was used.It was noted that,for a panel with an aspect ratio of 1.0,this would correspond to a curvature of a /R =0.067.The values of moment reduction using this approach were compared with those presented by Basler (Basler and Thurlimann 1961;Vincent 1969).Numerical results based on this limit were generated,and the following web-slenderness requirement was derived: 2 D 36,500a a =1?8.6?34 (1) ? ??? t R R F w ?y where D =unsupported distance between ?anges;and F y =yield stress in psi. An extension of this work was published a year later,when Culver et al.(1973)checked the accuracy of the isolated elas-tically supported cylindrical strips by treating the panel as a unit two-way shell rather than as individual strips.The ?ange/web boundaries were modeled as ?xed,and the boundaries at the transverse stiffeners were modeled as ?xed and simple.Longitudinal stiffeners were modeled with moments of inertias as multiples of the AASHO (Standard 1969)values for straight https://www.docsj.com/doc/0815619391.html,ing analytical results obtained for the slenderness required to limit the plate bending stresses in the curved panel to those of a ?at panel with the maximum allowed out-of-?atness (a /R =0.067)and with D /t w =330,the following equa-tion was developed for curved plate girder web slenderness with one longitudinal stiffener: D 46,000a a =1?2.9 ?2.2 (2) ? ? ? t R f R w ?b where the calculated bending stress,f b ,is in psi.It was further concluded that if longitudinal stiffeners are located in both the tension and compression regions,the reduction in D /t w will not be required.For the case of two stiffeners,web bending in both regions is reduced and the web slenderness could be de-signed as a straight girder panel.Eq.(1)is currently used in the ‘‘Load Factor Design’’portion of the Guide Speci?cations ,and (2)is used in the ‘‘Allowable Stress Design’’portion for girders stiffened with one longitudinal stiffener.This work was continued by Mariani et al.(1973),where the optimum trans-verse stiffener rigidity was determined analytically. During almost the same time,Abdel-Sayed (1973)studied the prebuckling and elastic buckling behavior of curved web panels and proposed approximate conservative equations for estimating the critical load under pure normal loading (stress),pure shear,and combined normal and shear loading.The linear theory of shells was used.The panel was simply supported along all four edges with no torsional rigidity of the ?anges provided.The transverse stiffeners were therefore assumed to be rigid in their directions (no strains could be developed along the edges of the panels).The Galerkin method was used to solve the governing differential equations,and minimum eigenvalues of the critical load were calculated and presented for a wide range of loading conditions (bedding,shear,and combined),aspect ratios,and curvatures.For all cases,it was demonstrated that the critical load is higher for curved panels over the comparable ?at panel and increases with an increase in curvature. In 1980,Daniels et al.summarized the Lehigh University ?ve-year experimental research program on the fatigue behav-ior of horizontally curved bridges and concluded that the slen-derness limits suggested by Culver were too severe.Equations for ‘‘Load Factor Design’’and for ‘‘Allowable Stress Design’’were developed (respectively)as D 36,500a =1?4?192(3)? ?t R F w ?y D 23,000a =1?4 ?170 (4) ? ? t R f w ?b The latter equation is currently used in the ‘‘Allowable Stress Design’’portion of the Guide Speci?cations for girders not stiffened longitudinally. Numerous analytical and experimental works on the subject have also been published by Japanese researchers since the end of the CURT project.Mikami and colleagues presented work in Japanese journals (Mikami et al.1980;Mikami and Furunishi 1981)and later in the ASCE Journal of Engineering Mechanics (Mikami and Furunishi 1984)on the nonlinear be-havior of cylindrical web panels under bending and combined bending and shear.They analyzed the cylindrical panels based on Washizu’s (1975)nonlinear theory of shells.The governing nonlinear differential equations were solved numerically by the ?nite-difference method.Simple support boundary condi-tions were assumed along the curved boundaries (top and bot-tom at the ?ange locations)and both simple and ?xed support conditions were used at the straight (vertical)boundaries.The large displacement behavior was demonstrated by Mi-kami and Furunishi for a range of geometric properties.Nu-merical values of the load,de?ection,membrane stress,bend-ing stress,and torsional stress were obtained,but no equations for design use were presented.Signi?cant conclusions include that:(1)the compressive membrane stress in the circumfer-ential direction decreases with an increase in curvature;(2)the panel under combined bending and shear exhibits a lower level of the circumferential membrane stress as compared with the panel under pure bending,and as a result,the bending moment carried by the web panel is reduced;and (3)the plate bending stress under combined bending and shear is larger than that under pure bending.No formulations or recommendations for direct design use were made. Kuranishi and Hiwatashi (1981,1983)used the ?nite-ele-ment method to demonstrate the elastic ?nite displacement be-havior of curved I-girder webs under bending using models with and without ?ange rigidities.Rotation was not allowed (?xed condition)about the vertical axis at the ends of the panel (transverse stiffener locations).Again,the nonlinear distribu-
