| 1 | 中澳水资源管理比较及启示(英文)显示文摘澳大利亚和中国都面临水资源管理的巨大挑战,本文比较了中澳两国在水资源管理方面的异同点。主要结论是:①除人均可利用水资源量外,中澳两国的水资源状况基本类似,两国的年均降雨量比较接近,降雨和径流都具较高的时空变异性;农用灌溉是主要的水利用方式,占年抽取水量的70%;两国都过度开发地表水和地下水,已经导致环境退化;②两国在管理制度和举措中却存在很大差别,相对而言,澳大利亚水管理体制简单可行,其通过伙伴关系建立的流域管理局在水资源综合管理中发挥了非常重要的作用。与此相反,中国有一个复杂的水管理系统,以自上而下的体系设置和跨部门协调为主;在灌溉水管理和流域管理中,澳大利亚已经把重点放在系统化的方法上,应用工程、技术、经济和体制方面的综合措施,相比之下,中国尽管制定了一些经济和体制方面的改革规划,但更重视工程和技术措施。这种水资源管理重点的差异,影响了两国在未来几年内水资源研究的重点,澳大利亚研究优先为政策和管理,而中国则重视技术开发和工程建设;③中国可以从澳大利亚的经验中受益的是系统化的水资源管理理念,包括:用系统化的思路提高水的利用效率,流域一体化的水资源管理以及加强科研和政策管理间的联系;两国也面临着一些共同挑战,包括气候变化、提高水的生产效率的同时恢复农业生态系统、以及理解地表水和地下水的相互关系。 | 尉永平 John Langford 夏军 占车生 柳文华 | 2009 | 资源科学2009，31，9： | 9 |
| 2 | 论变化环境下流域管理的知识创新显示文摘提出全球气候变化与世界社会经济动荡等变化环境下流域可持续发展的科学内涵、制约因素以及解决途径。以自然与社会协同进化的复杂系统作为变化环境下流域概念的抽象表征,以科研能力与管理能力作为流域可持续发展的重要影响因素,以流域管理中科学研究与管理实践的相互作用机理为出发点,分析当前流域管理中科学研究与管理实践的种种错位,提出适应变化环境的流域管理知识创新机制,为提高流域科研水平、充分发挥科学在流域可持续发展中的作用提供理论支撑。 | Wei Yongping 郑航 John Langford 程国栋 | 2012 | 地球科学进展2012，27，1： | 8 |
| 3 | Revisiting support optimization at the Driskos tunnel usinga quantitative risk approach显示文摘With the scale and cost of geotechnical engineering projects increasing rapidly over the past few decades,there is a clear need for the careful consideration of calculated risks in design.While risk is typically dealt with subjectively through the use of conservative design parameters,with the advent of reliability-based methods,this no longer needs to be the case.Instead,a quantitative risk approach can be considered that incorporates uncertainty in ground conditions directly into the design process to determine the variable ground response and support loads.This allows for the optimization of support on the basis of both worker safety and economic risk.This paper presents the application of such an approach to review the design of the initial lining system along a section of the Driskos twin tunnels as part of the Egnatia Odos highway in northern Greece.Along this section of tunnel,weak rock masses were encountered as well as high in situ stress conditions,which led to excessive deformations and failure of the as built temporary support.Monitoring data were used to validate the rock mass parameters selected in this area and a risk approach was used to determine,in hindsight,the most appropriate support category with respect to the cost of installation and expected cost of failure.Different construction sequences were also considered in the context of both convenience and risk cost. | J.Connor Langford N.Vlachopoulos M.S.Diederichs | 2016 | Journal of Rock Mechanics and Geotechnical Engineering2016，8，2： | 4 |
| 4 | 基于优化模型的城市供水多水源配置研究显示文摘在人口增长、社会发展和气候变化的多重影响下,城市缺水问题日益严重,多水源供水成为解决此问题的主要途径。本文建立了城市多水源供水优化模型,以澳大利亚墨尔本为例,针对不同气候和需水情景研究了海水淡化与外调水在城市供水系统的配置问题。结果显示,两种水源均能够提升需水临界点、提高供水可靠性,实现增强供水系统安全性的目标。正常气候条件下,两种水源对供水系统改善效果近似,考虑供水成本,应优先采用外调水水源;干旱气候条件下,稳定可靠的海水淡化水源优于受气候变化影响的外调水水源,但成本较高。增加供水水源、实施需求管理是保障城市供水系统安全的重要措施,城市供水多水源的配置应综合考虑供水可靠性与供水成本。 | 郑志磊 郑航 刘悦忆 LANGFORD John | 2020 | 水利水电技术2020，51，9： | 3 |
| 5 | Helicobacter pylori arginase mutant colonizes arginase Ⅱ knockout mice显示文摘AIM: To investigate the role of host and bacterial arginases in the colonization of mice by Helicobacter pylori (H.pylori).METHODS: H.pylori produces a very powerful urease that hydrolyzes urea to carbon dioxide and ammonium,which neutralizes acid.Urease is absolutely essential to H.pylori pathogenesis;therefore,the urea substrate must be in ample supply for urease to work efficiently.The urea substrate is most likely provided by arginase activity,which hydrolyzes L-arginine to L-ornithine and urea.Previous work has demonstrated that H.pylori arginase is surprisingly not required for colonization of wild-type mice.Hence,another in vivo source of the critical urea substrate must exist.We hypothesized that the urea source was provided by host arginase Ⅱ,since this enzyme is expressed in the stomach,and H.pylori has previously been shown to induce the expression of murine gastric arginase Ⅱ.To test this hypothesis,wild-type and arginase (rocF) mutant H.pylori strain SS1 were inoculated into arginase Ⅱ knockout mice.RESULTS: Surprisingly,both the wild-type and rocF mutant bacteria still colonized arginase Ⅱ knockout mice.Moreover,feeding arginase Ⅱ knockout mice the host arginase inhibitor S-(2-boronoethyl)L-cysteine (BEC),while inhibiting > 50% of the host arginase Ⅰ?activity in several tissues,did not block the ability of the rocF mutant H.pylori to colonize.In contrast,BEC poorly inhibited H.pylori arginase activity.CONCLUSION: The in vivo source for the essential urea utilized by H.pylori urease is neither bacterial arginase nor host arginase Ⅱ;instead,either residual host arginase Ⅰ?or agmatinase is probably responsible. | Songhee H Kim Melanie L Langford Jean-Luc Boucher Traci L Testerman David J McGee | 2011 | World Journal of Gastroenterology2011，17，28： | 3 |
| 6 | 参数振动系统亚谐共振理论的新结果:退化分叉解显示文摘本文应用Liapunov-schmidt方法和奇异性理论,首次研究了参数激励非线性振动系统亚谐共振情况下的退化分叉解,这里的退化是指在分叉方程(10)中a_1=0时的情况,这种情况工程振动系统中有时会遇到.文中给出了用Liapunov-schmidt方法计算分叉方程系数的简有效的方法,使计算工作量大大减少.奇异性理论的应用,证明了系统在a_1=0的情况下为余三,这时系统呈现出十分复杂、有趣的动力学现象,如图2所示,从而使我们对该类非线性振动统动力学行为有了更深的了解.一般认为,参数振动系统只有当ε>δ时才可能有周期解,但本证明了由于Strutt图顶点的后移,在ε<δ时也可能存在周期解.数值计算表明,本文的理论果有足够的精度. | 陈予恕 詹凯君 Langford W.F. | 1990 | 振动工程学报1990，3，2： | 3 |
