1应用IVE模型计算上海市机动车污染物排放显示文摘为了解上海市机动车污染现状,建立上海市机动车源排放清单,分别选择上海市中心城区、商业区和收入相对较低区域中的主干道、快速道和次干道3种共9条典型道路,开展机动车技术水平参数、比功率(VSP)分布状况、启动状况等测试,并在此基础上将InternationalVehicleEmission(IVE)模型本地化.调查结果表明,上海市区实际道路上轻型客车、出租车、公交巴士、卡车和摩托车(包含助动车)分别占道路总车流量的41.0%、30.8%、15.6%、6.9%和5.7%;从技术组成看,约85%的轻型客车和97%的出租车均安装有三元催化装置,约30%的公交巴士和90%的卡车没有达到欧I标准;机动车的VSP分布主要集中在-2.9~1.2kW·t-1.模式计算结果表明,2004年上海市机动车CO、VOC、NOx和PM排放量分别为57.06×104t、7.75×104t、9.20×104t和0.26×104t;20%的高排放车对总排放量的贡献占到25%~45%;启动过程中排放的CO、VOC和PM占总排放量的15%~25%,NOx仅占总排放量的4.5%.王海鲲 陈长虹 黄成 潘汉生 景启国 王冰研 戴懿 赵静 李莉 James Lents Matthew Barth Richard Nikkila 钱华 戴海夏 2006环境科学学报2006,26,1:68
2重型机动车实际排放特性与影响因素的实测研究显示文摘利用美国Sensors公司生产的SEMTECHD车载排放测试仪在上海随机选择了7辆重型柴油车开展实际道路的排放测试,该实验累积测试道路长度为186km,共取得29090个逐秒的有效工况点数据,其中城市主干道12979个,次干道12368个,快速干道3743个.给出了车辆在不同道路上的工况点分布,分析了速度、加速度对燃油消耗、尾气排放的影响.测试结果表明,在选定的城市道路上,车流的平均怠速工况比为17%,加速工况比23.6%,等速工况比为31.0%,减速工况比为28.5%.被测车辆的CO、THC、NOx平均排放因子分别为(4.41±2.46)g·km-1、(1.77±1.17)g·km-1和(6.96±1.93)g·km-1,车辆排放状况因车速、加速度等因素而不同.测试结果基本反映了目前上海道路的交通状况和柴油卡车的排放现状,同时也说明过低的车速和频繁加减速是加重机动车污染的重要原因.陈长虹 景启国 王海鲲 潘汉生 李莉 黄成 赵静 戴懿 黄海英 Matt Barth Nick Nikkila 2005环境科学学报2005,25,7:57
3重型柴油车实际道路排放与行驶工况的相关性研究显示文摘采用SEMTECH-D车载排放测试仪测量了东风柴油卡车在城市实际道路工况以及等速和加速工况下的油耗及污染物排放状况.测试结果显示,测试卡车实际道路综合百公里油耗为17.8L,NOx、CO和Hc排放因子分别为3.96、8.86和2.15g ·km^-1.其中主干道路况相对较差,油耗与排放因子较高,是所有测试道路平均水平的1.3-1.8倍左右.研究结果表明,重型车油耗及污染物排放与各行驶工况下的速度、加速度均密切相关,车辆在高速加速行驶状态下易产生高排放.车辆在30~50km·h^-1速度区间内等速行驶时。油耗与排放因子最为经济且环境友好.车辆在加速行驶时,油耗与NOx、CO排放因子可达到城市实际道路平均水平的2.0、2.2、1.4倍,急加速时达到2.8、2.1、14倍.应用比功率概念可准确描述车辆在各运行工况下的排放水平,但在重型车上缺乏实验依据,有待进一步研究.黄成 陈长虹 景启国 潘汉生 王海鲲 黄海英 李莉 赵静 戴懿 Matthew Barth Richard Nikkila 2007环境科学学报2007,27,2:41
4轻型柴油车排放特性与机动车比功率分布的实例研究显示文摘引入机动车比功率概念研究了驾驶条件(Diving Condition)对机动车排放的影响及二者间的关系.利用美国Sensors公司生产的SEMTECHD车载排放测试仪在上海选取2辆轻型柴油客货两用车开展了实际道路排放测试.测试道路包括城市快速道、主干道和次干道,2辆轻型车测试的道路全长分别为31.8和39.7 km.通过计算逐秒的比功率值,研究了实际行驶中机动车比功率(VSP)与机动车油耗、空燃比和污染物排放的关系.回归分析结果表明,比功率比加速度能够更好地反映与NOx排放之间的关系,不同道路上机动车的CO、TC、NOx排放速率和油耗的比功率区间(VSP bin)分布具有较好的一致性.实测研究中VSP bin分布于-20~20 kW·t-1的范围内,其中超过50%的数据分布在-3~1 kW·t-1之间.高排放集中在分布频率较低的高VSP区间.应用污染物排放与VSP分布的关系式和VSP bins的频率分布可以估算机动车污染物排放总量.排放速率计算式具有一定的不确定性,还有待将来进一步修正.潘汉生 陈长虹 景启国 黄成 黄海英 王海鲲 李莉 赵静 戴懿 蔺宏轶 王少俊 Matt Barth Nick Nikkila 2005环境科学学报2005,25,10:30
5智能网联汽车协同生态驾驶策略综述显示文摘为了跟踪近年来智能网联汽车(CAV)协同生态驾驶策略的研究进展,分析了车辆、驾驶行为、交通网络和社会这4类因素对CAV能耗的影响程度,以车辆、基础设施和旅行者为对象对目前CAV生态研究进行分类,重点分析了信号交叉口生态驶入与离开、生态协同自适应巡航控制、匝道合流区生态协同驾驶、生态协同换道轨迹规划和生态路由5种典型车辆协同生态驾驶应用场景的研究现状。分析结果表明:相比人类驾驶方式,在任何交通流量CAV 100%渗透率的条件下和低交通流量CAV部分渗透率的条件下,CAV油耗节省效果显著,最高可达63%,而具有部分智能化和网联化等级的CAV油耗可至少节省7%;现有研究较少考虑人机共驾情况下,驾驶人反应延迟和自动控制器传输延迟导致的轨迹跟踪偏离;现有研究将车车通信/车路通信假定为理想数据交互过程,未考虑通信拓扑、传输时延、通信失效与基站切换等因素对CAV生态协同驾驶策略的影响;现有研究较少探讨多车道、交叉口转向-直行共用车道和U型车道等交通场景,以及不同智能网联等级CAV与人类驾驶汽车、行人、自行车等共存的混合交通条件下的生态驾驶策略;受限于自动驾驶技术和基础设施尚未成熟和完善,真实交通场景下的测试验证工作尚未开展;车辆控制、车车通信、多车协同、混合交通流场景、半实物仿真测试和真实交通场景测试等方面将是CAV协同生态驾驶策略的进一步发展方向。杨澜 赵祥模 吴国垣 徐志刚 MATTHEW Barth 惠飞 郝鹏 韩梦杰 赵周桥 房山 景首才 2020交通运输工程学报2020,20,5:26
6重型柴油车车载排放实测与加载影响研究显示文摘采用车载排放测试仪,对2辆重型柴油卡车在空载和加载条件下进行实际道路车载排放测试.通过分析获得了油耗与排放速率的速度一加速度及其工况点的分布,发现高油耗与高排放工况点主要集中在高速加速区域,加载时油耗与排放高值随工况点分布更广;车辆在(30±2.5)km·h^-1等速及加速行驶时受加载影响最大,此时加载油耗与排放约是空载的1.6~3.2倍左右;由实测结果发现,卡车Ⅰ和卡车Ⅱ加载时油耗及CO、HC、NO,排放因子分别是空载的1.6倍、3.5倍、1.1倍、1.5倍以及1.2倍、1.0倍、0.9倍和1.5倍,加载对油耗与NO,排放影响最为明显,对HC影响最小,CO影响取决于车辆保养水平;卡车Ⅱ较卡车Ⅰ车型更大,发动机功率更高,相同荷载时受加载影响较小,说明重型车在发动机负荷可承受的范围内合理装载,有助于避免油耗与排放恶化,提高燃油经济性和排放水平.黄成 陈长虹 景启国 潘汉生 王海鲲 李莉 黄海英 赵静 戴懿 王少俊 蔺宏轶 Matthew Barth Richard Nikkila 2006环境科学2006,27,11:18
7公交柴油车道路排放特征的实测研究初探显示文摘利用GPS和SEMTECH—D车载排放测试仪测量了上海市公交车行驶工况和公交柴油车在市区道路上的排放状况.该研究共获得193400组公交车行驶工况数据,累计测量里程820km,排放数据75420个.测量结果显示,上海市公交车平均车行速度14km·h^-1,最高车速为60km·h^-1;市区公交车平均车行速度14km·h^-1,最高车速小于60km·h^-1,市区公交车的怠速时间比在25%以上.被测公交柴油车的CO、THC和NOx平均里程排放因子为(3.41±0.86)、(1.95±0.47)和(4.56±0.99)g·km^-1,与陈长虹等人2005年提供的卡车3和卡车5的排放状况相近.测量结果还显示,被测车辆进出站时单位里程排放量是正常行驶条件下的10倍.此外,在交通高峰期或拥堵期,车行速度降低至0—5km·h^-1时,被测公交柴油车的CO、THC和NOx平均里程排放因子升高至17.49、6.68和15.85g·km^-1,是平均车速时候的5.13倍、3.4倍和3.48倍,车辆排放污染将明显加剧。测量结果说明,加强城市交通管理,减少车辆拥堵,不仅可以提高公交车运行效率,而且也是降低公交车污染的有效措施。景启国 陈长虹 潘汉生 黄成 李莉 黄海英 王海鲲 赵静 戴懿 Matthew Barth Richard Nikkila 2006环境科学学报2006,26,9:17

9Proposal of an ultrasonographic classification for hepatic alveolar echinococcosis: Echinococcosis multilocularis Ulm classification-ultrasound显示文摘AIM: To establish an ultrasonographic classification based on a large sample of patients with confirmed hepatic alveolar echinococcosis(AE).METHODS: Clinical data and ultrasonography(US) findings of 185 patients(100 males; 85 females; mean age at diagnosis: 51.4 ± 17.6 years; mean age at time of US examination: 58.7 ± 18.2 years) were retrospectively reviewed with respect to the US morphology of hepatic AE lesions. The sonomorphological findings were grouped according to a five-part classification scheme.RESULTS: Application of the new classification resulted in the following distribution of sonomorphological patterns among the patients examined: hailstorm(54.1%); pseudocystic(13.5%); ossification(13.0%); hemangioma-like(8.1%); and metastasis-like(6.5%). Only 4.9% of lesions could not be assigned to a sonomorphological pattern.CONCLUSION: The sonomorphological classification proposed in the present study facilitates the diagnosis,interpretation and comparison of hepatic alveolar echinococcosis in routine practice and in the context of scientific studies.Wolfgang Kratzer Beate Gruener Tanja EM Kaltenbach Sarina Ansari-Bitzenberger Peter Kern Michael Fuchs Richard A Mason Thomas FE Barth Mark M Haenle Andreas Hillenbrand Suemeyra Oeztuerk Tilmann Graeter 2015World Journal of Gastroenterology2015,21,43:16
10Alveolar echinococcosis-spreading disease challenging clinicians: A case report and literature review显示文摘Human alveolar echinococcosis (AE) is a potentially deadly disease; recent studies have shown that the endemic area of Echinococcus multilocularis , its causative agent, is larger than previously known. This disease has low prevalence and remains underreported in Europe. Emerging clinical data show that diagnostic difficulties are still common. We report on a 76-year old patient suffering from AE lesions restricted to the left lobe of the liver who underwent a curative extended left hemihepatectomy. Prior to the resection a liver biopsy under the suspicion of an atypical malignancy was performed. After the intervention he developed a pseudoaneurysm of the hepatic artery that was successfully coiled. Surprisingly, during surgery, the macroscopic appearance of the tumour revealed a growth pattern that was rather typical for cystic echinococcosis (CE), i.e. , a gross tumour composed of multiple large vesicles with several centimeters in diameter. In addition, there were neither extensive adhesions nor infiltrations of the neighboring pancreas and diaphragm as was expected from previous imaging results. The unexpected diagnosis of AE was confirmed by definite histopathology, specific polymerase chain reaction and serology results. This is a rare case of unusual macroscopic presentation of AE that posed immense diagnostic challenges and had an eventful course. To our knowledge this is the first case of an autochthonous infection in this particular geographic area of Germany, the federal state of Saxony. This report may provide new hints for an expanding area of risk for AE and emphasizes the risk of complications in the scope of diagnostic procedures and the limitations of modern radiological imaging.Georgi Atanasov Christoph Benckert Armin Thelen Dennis Tappe Matthias Frosch Dieter Teichmann Thomas FE Barth Christian Wittekind Stefan Schubert Sven Jonas 2013World Journal of Gastroenterology2013,19,26:14
11Hepatitis C virus:Is it time to say goodbye yet? Perspectives and challenges for the next decade显示文摘The majority of individuals exposed to hepatitis C virus(HCV) establish a persistent infection,which is a leading cause of chronic liver disease,cirrhosis and hepatocellular carcinoma.Major progress has been made during the past twenty-five years in understanding the HCV life cycle and immune responses against HCV infection.Increasing evidence indicates that host genetic factors can significantly influence the outcome of HCV infection and the response to interferon alpha-based antiviral therapy.The arrival of highly effective and convenient treatment regimens for patients chronically infected with HCV has improved prospects for the eradication of HCV worldwide.Clinical trials are evaluating the best anti-viral drug combination,treatment doses and duration.The new treatments are better-tolerated and have shown success rates of more than 95%.However,the recent breakthrough in HCV treatment raises new questions and challenges,including the identification of HCVinfected patients and to link them to appropriate health care,the high pricing of HCV drugs,the emergence of drug resistance or naturally occurring polymorphism in HCV sequences which can compromise HCV treatment response.Finally,we still do not have a vaccine against HCV.In this concise review,we will highlight the progress made in understanding HCV infection and therapy.We will focus on the most significant unsolved problems and the key future challenges in the management of HCV infection.Heidi Barth 2015World Journal of Hepatology2015,7,5:12
12Proposal of a computed tomography classification for hepatic alveolar echinococcosis显示文摘AIM: To establish a computed tomography(CT)-morphological classification for hepatic alveolar echinococcosis was the aim of the study. METHODS: The CT morphology of hepatic lesions in 228 patients with confirmed alveolar echinococcosis(AE) drawn from the Echinococcus Databank of the University Hospital of Ulm was reviewed retrospectively. For this reason, CT datasets of combined positron emission tomography(PET)-CT examinations were evaluated. The diagnosis of AE was made in patientswith unequivocal seropositivity; positive histological findings following diagnostic puncture or partial resection of the liver; and/or findings typical for AE at either ultrasonography, CT, magnetic resonance imaging or PET-CT. The CT-morphological findings were grouped into the new classification scheme.RESULTS: Within the classification a lesion was dedicated to one out of five 'primary morphologies' as well as to one out of six 'patterns of calcification'. 'primary morphology' and 'pattern of calcification' are primarily focussed on separately from each other and combined, whereas the 'primary morphology' V is not further characterized by a 'pattern of calcification'. Based on the five primary morphologies, further descriptive sub-criteria were appended to types Ⅰ-Ⅲ. An analysis of the calcification pattern in relation to the primary morphology revealed the exclusive association of the central calcification with type Ⅳ primary morphology. Similarly, certain calcification patterns exhibited a clear predominance for other primary morphologies, which underscores the delimitation of the individual primary morphological types from each other. These relationships in terms of calcification patterns extend into the primary morphological sub-criteria, demonstrating the clear subordination of those criteria.CONCLUSION: The proposed CT-morphological classification(EMUC-CT) is intended to facilitate the recognition and interpretation of lesions in hepatic alveolar echinococcosis. This could help to interpret different clinical courses better and shall assist in the context of scientific studies to improve the comparability of CT findings.Tilmann Graeter Wolfgang Kratzer Suemeyra Oeztuerk Mark Martin Haenle Richard Andrew Mason Andreas Hillenbrand Thomas Kull Thomas F Barth Peter Kern Beate Gruener 2016World Journal of Gastroenterology2016,22,13:10

16交通拥堵与温室气体排放显示文摘缓解拥堵项目可减少温室气体排放,但基于单个变量(如仅基于出行距离)的CO2排放预测并不精确。为了准确预测缓堵项目减少的CO2排放量,利用车辆运行检测技术、车辆活动数据库及根据车辆类型设计的排放模型,通过分析速度与排放的关系绘制速度-排放曲线,并结合交通运行检测数据,评价缓堵策略、速度管理策略、交通平滑策略等交通运行管理技术在CO2减排方面的作用。以南加州某高速公路为例进行的研究显示,上述三项交通管理策略中任何一项都可减少7%~12%的CO2排放量;三条策略同时使用可减少大约30%的CO2排放量。Matthew Barth Kanok Boriboonsomsin 邵玲 2012城市交通2012,10,1:5

19Neutralizing antibodies in hepatitis C virus infection显示文摘Hepatitis C virus (HCV) is a major cause of hepatitis world-wide. The majority of infected individuals develop chronic hepatitis which can then progress to liver cirrhosis and hepatocellular carcinoma. Spontaneous viral clearance occurs in about 20%-30% of acutely infected individuals and results in resolution of infection without sequaelae. Both viral and host factors appear to play an important role for resolution of acute infection. A large body of evidence suggests that a strong, multispecific and long-lasting cellular immune response appears to be important for control of viral infection in acute hepatitis C. Due too the lack of convenient neutralization assays, the impact of neutralizing responses for control of viral infection had been less defined. In recent years, the development of robust tissue culture model systems for HCV entry and infection has finally allowed study of antibody-mediated neutralization and to gain further insights into viral targets of host neutralizing responses. In addition, detailed analysis of antibody-mediated neutralization in individual patients as well as cohorts with well defined viral isolates has enabled the study of neutralizing responses in the course of HCV infection and characterization of the impact of neutralizing antibodiesfor control of viral infection. This review will summarize recent progress in the understanding of the molecular mechanisms of antibody-mediated neutralization and its impact for HCV pathogenesis.Mirjam B Zeisel Samira Fafi-Kremer Isabel Fofana Heidi Barth Franoise Stoll-Keller Michel Doffo■l Thomas F Baumert 2007World Journal of Gastroenterology2007,13,36:3
