| 1 | 大别山的构造变形期次和超高压岩石折返的动力学显示文摘从构造关系上看,大别山可分为南部,中部和北部3个构造系统。大别山南部构造系统为一套(原地)构造堆叠系统(相对的),从上到下依次为:①未变质的震旦纪—早三叠世沉积盖层,它被造山后的侏罗—白垩纪砂-砾岩不整合覆盖;②弱变质的新元古代板岩;③高压变质岩系(宿松群),这些变质岩系大多退变质为绿片岩相;④含柯石英榴辉岩超高压变质单元的异地系统;⑤未经历超高压变质作用的原地(相对的)片麻岩系。北西-南东向的拉伸线理在各个地质单元均有表现。从动力学上看,上盘指向NW的剪切运动被后期的褶皱所改变。大别山中部为(混合岩)热穹窿改造系统,系经历了超高压变质作用的地体叠加了混合岩化作用的产物,它与超高压变质地体的界限为一拆离断层,而正是这个拆离断层使超高压变质地体向地表折返并经历了角闪岩相的退变质作用。大别山北部为构造堆叠系统,早期的面理和南北向的挤压线理被轴面北倾的褶皱所改造,这种褶皱对应于大别山中部同折返期的韧性变形的隆升构造。同时建立了地球动力学模型并讨论了逆冲作用和正断层的作用。 | 林伟 王清晨 Michel Faure 孙岩 舒良树 Urs Scharer | 2003 | 地质学报2003,77,1: | 42 |

| 3 | 欧盟农业和环境政策对化肥消费和生产的影响显示文摘农业施肥引起的环境污染不仅在发达国家,而且在发展中国家也日益受到重视。自1992年欧盟实施以农业环境一揽子计划为主导思想的新的共同农业政策以来,已有效地控制了农业生产对环境的污染。但该政策也对欧盟化肥消费和生产造成了严重的影响。本文通过欧盟农业和环境政策对保护环境及对肥料生产消费影响的介绍,为国内了解欧盟目前农业和环境状况以及制定农业生产、环境保护政策和化肥生产方向提供借鉴。由于国内化肥用量过高,肥料养分利用率低,环境污染严重,尽管目前还没有类似欧盟农业和环境政策的法规,但相信不久的将来政府也会提出相应的法规,因此,化肥行业必须抓紧研究相关问题,尽快制定应对措施。 | 卓懋白 胡云才 Urs Schmidhalter | 2004 | 磷肥与复肥2004,19,2: | 21 |

| 5 | 从德国农业氮投入来认识中国氮污染的严重性及应采取的对策显示文摘为解决中国人多地少所带来巨大的粮食生产压力,近20年来,中国的氮肥消耗大幅度增加。2000年,中国氮肥消耗已占世界总氮肥消耗量的30%,氮肥用量超过225kg/hm2,在个别地区超过500kg/hm2,氮肥利用率仅为30%~40%,远低于发达国家70%~80%的水平,导致了环境污染。德国也曾经历为加速农业生产而大量使用氮肥,并带来环境污染这一发展阶段。20世纪80年代,德国开始制定一系列法规和政策减少氮肥使用,在氮肥消耗量下降的情况下,不但残留氮污染环境的问题得到有效遏制和缓解,而且粮食单产还继续保持增长势头。借鉴德国的发展经验,中国有必要制订相关法规和政策,通过大力提高氮肥利用率,以避免氮肥的过度使用。 | 胡云才 GUTSER Reinhold SCHMIDHALTER Urs | 2004 | 磷肥与复肥2004,19,5: | 14 |
| 6 | 离子液体微波辅助萃取川芎中内酯类化合物显示文摘以离子液体1-丁基-3-甲基咪唑双三氟甲基磺酰亚胺鎓盐([Bmim]Tf2N)为萃取剂,采用微波辅助萃取法(MAE)对川芎中的洋川芎内酯I和H及藁本内酯的萃取进行了研究.考察了温度、时间、相比和原药粒径等因素对萃取效果的影响,比较了MAE和传统溶剂回流萃取法(SRE)的萃取率,并对萃取后的固体做了SEM研究.结果表明,萃取温度对萃取率影响显著,在180℃下对3种内酯类化合物均体现出良好的萃取效率;萃取在1min内达到平衡;固/液比为1/30~1/5g/mL和原药粒径0.096~0.25mm范围内对萃取效率没有显著影响;与SRE相比,MAE耗时短、效率高,对提高藁本内酯萃取效率尤为显著,提高达46%;由样品表面结构变化可见,MAE萃取的样品结构被破坏,有助于活性组分释放、提高萃取率. | 张之达 陈吉平 李长平 颜佩芳 王安杰 Urs Welz-Biermann | 2010 | 过程工程学报2010,10,3: | 14 |

| 9 | 基于光谱指数波段优化算法的小麦玉米冠层含氮量估测显示文摘作物关键生育时期冠层氮素含量的实时监测对于优化氮肥用量和减少环境风险具有重要的意义。为了寻求预测不同作物氮素含量的最佳光谱参数,实现作物氮素无损营养诊断。本研究通过2008年—2011年在德国慕尼黑弗莱辛和河北曲周的不同氮量的小麦玉米田间试验,采用高光谱仪获取小麦玉米冠层的反射光谱,利用光谱理论模型进行光谱指数波段的优化,从而抽取不同冠层结构条件下的小麦玉米氮素营养敏感波段。结果表明与传统的基于红光的光谱指数相比,优化光谱指数显著提高了小麦玉米冠层氮素含量的预测能力,克服了传统的基于红光光谱指数的饱和问题。优化光谱指数的波段结合随着作物品种及其冠层结构的变化而变化,其优化波段范围主要集中在红边(730~760nm)和红边向近红外的过渡区域(760~880nm)。优化结果显示玉米最佳光谱指数为R_(λ766)/R_(λ738)-1,小麦最佳光谱指数为R_(λ796)/R_(λ760)-1,玉米小麦相结合优化后的最佳光谱指数为R_(λ876)/R_(λ730)-1。结果进一步验证了优化光谱指数估测的不同作物含氮量的预测值与实测值相关性最高,且验证偏差最小,证实了优化后的光谱特征参数可对不同作物氮素丰缺状况进行快速、准确、无损估测。试验结果也为设计作物冠层氮素传感器和更好的利用现有基于卫星的传感器实施区域上的作物氮素营养监测提供了理论基础。 | 李丹 李斐 胡云才 Mistele Bodo Urs Schmidhalter | 2016 | 光谱学与光谱分析2016,36,4: | 11 |
| 10 | 离子液体[C_npy][NTf_2](n=2,4,5)的动力粘度和电导率(英文)显示文摘在298.15-338.15K和283.15-338.15K温度范围内,分别测量了N-烷基吡啶双三氟甲磺酸亚胺(烷基链分别为:乙基、丁基、戊基)三种疏水型离子液体的动力粘度和电导率.利用Arrhenius方程和Fulcher方程将测量的动力粘度和电导率对温度拟合,得到了动力粘度和电导率随温度变化方程式.从电导率和密度计算出了上述三种离子液体在283.15-338.15K温度范围内的摩尔电导率.应用Walden规则,描述了动力粘度与摩尔电导率之间的关系. | 刘青山 颜佩芳 杨淼 谭志诚 李长平 WELZ-BIERMANN Urs | 2011 | 物理化学学报2011,27,12: | 11 |
| 11 | 曲安奈得:用于玻璃体内注射的配制法显示文摘目的:具有抗增生、抗水肿、抗炎和血管稳定作用的曲安奈得(TA)混悬液在眼水肿、新生血管和增生性疾病,特别是黄斑疾病的应用正在不断增加。本文描述玻璃体内注射用的TA的配制法并分析赋形剂(苯甲基乙醇)过滤后的实际剂量。方法:从40mgVolonA瓶中,相当于Kenalog40mg,抽取0.625mL结晶混悬液,相当于TA25mg。在无菌条件下,过滤混悬液以去除溶剂苯甲基乙醇,结晶体用9g/L氯化钠洗涤4次,进行TA玻璃体注射。需要密切随访,监测在头2wk内的眼内炎和1 ̄2mo的高眼压。结果:预期25mgTA的浓度在溶剂过滤后测量为23.8mg。在另一个药学实验室,同样过滤后结果是12.8mg,均不是预期的剂量25mgTA。结论:还没有玻璃体内注射TA的标准剂量。手术医生应该知道过滤后玻璃体内注射TA的剂量将比预期的要少。需要在注射后密切随访:在第1wk监测无菌性眼内炎或假性眼内炎,在第2wk要识别感染性眼内炎,它可能出现在无痛和不充血的眼,但必须立即治疗。继发性高眼压可能在注射后1 ̄2mo发生;一般可用抗青光眼药物控制。 | Ingrid Kreissig Jost B.Jonas Urs Vossmerbaeumer 王琳 惠延年 | 2005 | 国际眼科杂志2005,5,5: | 11 |

| 15 | 田间土壤硝态氮快速测定方法的研究与应用前景显示文摘对田间土壤硝态氮(NO3N)快速测定方法的研究,包括土壤水分快速测定方法、快速提取技术(经济、易于获得的提取剂和简易、快捷的提取方法)、温度校正系数以及合理使用试纸反射仪的研究。大量的试验结果表明,田间土壤硝态氮快速测定方法所得的土壤硝态氮含量与实验室标准方法所得结果有着良好的线性相关关系。本研究所提出的田间土壤硝态氮快速测定方法具有经济、操作简单、便于农民掌握等特点。目前中国存在着施肥不合理的现象,亟须简易可靠的田间测土技术,因此,田间土壤硝态氮快速测定方法在中国将有着广阔的应用前景。 | Urs Schm idhalter 胡云才 | 2006 | 磷肥与复肥2006,21,3: | 8 |
| 16 | Ductal adenocarcinoma of the pancreatic head:A focus on current diagnostic and surgical concepts显示文摘Complete surgical resection still remains the only possibility of curing pancreatic cancer,however,only 10% of patients undergo curative surgery.Pancreatic resection currently remains the only method of curing patients,and has a 5-year overall survival rate between 7%-34% compared to a median survival of 3-11 mo for unresected cancer.Pancreatic surgery is a technically demanding procedure requiring highly standardized surgical techniques.Nevertheless,even in experienced hands,perioperative morbidity rates(delayed gastric emptying,pancreatic fistula etc.) are as high as 50%.Different strategies to reduce postoperative morbidity,such as different techniques of gastroenteric reconstruction(pancreatico-jejunostomy vs pancreatico-gastrostomy),intraoperative placement of a pancreatic main duct stent or temporary sealing of the main pancreatic duct with fibrin glue have not led to a significant improvement in clinical outcome.The perioperative application of somatostatin or its analogues may decrease the incidence of pancreatic fistulas in cases with soft pancreatic tissue and a small main pancreatic duct(< 3 mm).The positive effects of external pancreatic main duct drainage and antecolic gastrointestinal reconstruction have been observed to decrease the rate of pancreatic fistulas and delayed gastric emptying,respectively.Currently,the concept of extended radical lymphadenectomy has been found to be associated with higher perioperative morbidity,but without any positive impact on overall survival.However,there is growing evidence that portal vein resections can be performed with acceptable low perioperative morbidity and mortality but does not achieve a cure. | Mehdi Ouassi Urs Giger Guillaume Louis Igor Sielezneff Bernard Sastre Olivier Farges | 2012 | World Journal of Gastroenterology2012,18,24: | 7 |
| 17 | Response to endoscopic therapy for biliary anastomotic strictures in deceased versus living donor liver transplantation显示文摘BACKGROUND:Endoscopic therapy has been successful in the management of biliary complications after both deceased donor liver transplantation(DDLT) and living donor liver transplantation(LDLT).LDLT is thought to be associated with higher rates of biliary complications,but there are few studies comparing the success of endoscopic management of anastomotic strictures between the two groups.This study aims to compare our experience in the endoscopic management of anastomotic strictures in DDLT versus LDLT.METHODS:This is a retrospective database review of all liver transplant patients undergoing endoscopic retrograde cholangiopancreatography(ERCP) after liver transplantation.The frequency of anastomotic stricture and the time to develop and to resolve anastomotic stricture were compared between DDLT and LDLT.The response of anastomotic stricture to endoscopic therapy was also analyzed.RESULTS:A total of 362 patients underwent liver transplantation between 2003 and 2011,with 125 requiring ERCP to manage biliary complications.Thirty-three(9.9%) cases of DDLT and 8(27.6%) of LDLT(P=0.01) were found to have anastomotic stricture.When comparing DDLT and LDLT,there was no difference in the mean time to the development of anastomotic strictures(98±17 vs 172±65 days,P=0.11),likelihood of response to ERCP [22(66.7%) vs 6(75.0%),P=0.69],mean time to the resolution of anastomotic strictures(268±77 vs 125±37 days,P=0.34),and the number of ERCPs required to achieve resolution(3.9±0.4 vs 4.7±0.9,P=0.38).CONCLUSIONS:Endoscopic therapy is effective in the majority of biliary complications relating to liver transplantation.Anastomotic strictures occur more frequently in LDLT compared with DDLT,with equivalent endoscopic treatment response and outcomes for both groups. | Calvin HY Chan Fergal Donnellan Michael F Byrne Alan Coss Mazhar Haque Holly Wiesenger Charles H Scudamore Urs P Steinbrecher Alan A Weiss Eric M Yoshida | 2013 | Hepatobiliary & Pancreatic Diseases International2013,12,5: | 7 |

| 20 | Early life exposure to per-and polyfluoroalkyl substances(PFASs):A critical review显示文摘Due to the dynamic developmental processes during pregnancy,infancy,childhood and adolescence,exposure to PFASs is hypothesized to have the most pronounced negative effects during this period.In this review we critically evaluate the current state of the science regarding human early life exposure processes(until 18 years of age)to per-and polyfluoroalkyl substances(PFASs).Efficient placental transfer of perfluoroalkyl acids(PFAAs)results in relatively high prenatal exposure compared with many neutral organic contaminants.The few biomonitoring studies that specifically target infants,toddlers and other children suggest relatively high serum concentrations of perfluorooctane sulfonic acid(PFOS)and perfluorooctanoic acid(PFOA)in early life with peak concentrations occurring sometime before the child reaches 20 months.This peak in serum concentrations is most likely explained by exposure via breastfeeding,ingestion of house dust and/or specific contact events with consumer products leading to high body weight normalized estimated daily intakes(EDIs).Although children have higher EDIs of PFASs than adults,these are not always reflected by higher serum levels of PFASs in children in cross-sectional biomonitoring studies due to the confounding effect of age and birth cohort,and different exposure histories due to production changes.Longitudinal exposure studies measuring internal and external exposure(for multiple pathways and PFASs)at several time points during early life are strongly encouraged to understand temporal changes in exposure of individual children.A better quantitative understanding of early life exposure processes would help to improve the validity of epidemiological studies and allow informed decisions regarding setting of regulatory thresholds and appropriate mitigation actions. | Kerstin Winkens Robin Vestergren Urs Berger Ian TCousins | 2017 | Emerging Contaminants2017,3,2: | 6 |
