| 1 | Effect of Laser Power on Microstructure and Wear Resistance of WC_P/Ni Cermet Coating显示文摘Laser cladding nickel-based alloy coating (Ni60) and nickel-based composite coating doped with WC par-ticles by 35 %( WCP/Ni) were produced onthelow-carbon steel substrate by CO2continuous wavelaser with pow-er of 5 kWusing theinjected powder technique . The effect of laser power on microstructure and wear resistance oflaser cladding WCP/Ni cermet coating was investigated . The WC_P/Ni alloy coating with evenly distributed WCce-ramic phases and the better bond with the substrate alloy was obtained at a power of 2·2 kW. Diffusion solutionreaction happened between WC particles and the substrate alloy during laser cladding ,and led to the formation ofblock rich-tungsten carbide on the edges of the WC particles ,especially at higher power . The WC_P/Ni alloy coat-ing consists of the undissolved WC particles ,the block or dendritic rich-tungsten carbide ,the bar-like rich-chromi-umcarbide ,and dendrite solid solution and eutectic structure among the carbides . Microhardness and wear resist-ance of the WC_P/Ni coating at different powers were much higher or better than those of Ni60 alloy coating ,andthe best results were obtained at power of 2·2 kW. | SI Song-hua YUAN Xiao-min LIU Yue-long HE Yi-zhu Keesam Shin | 2006 | Journal of Iron and Steel Research(International)2006，13，3： | 6 |
| 2 | Constructing confidence intervals of extreme rainfall quantiles using Bayesian,bootstrap,and profile likelihood approaches显示文摘Hydrological risk is highly dependent on the occurrence of extreme rainfalls.This fact has led to a wide range of studies on the estimation and uncertainty analysis of the extremes.In most cases,confidence intervals(CIs)are constructed to represent the uncertainty of the estimates.Since the accuracy of CIs depends on the asymptotic normality of the data and is questionable with limited observations in practice,a Bayesian highest posterior density(HPD)interval,bootstrap percentile interval,and profile likelihood(PL)interval have been introduced to analyze the uncertainty that does not depend on the normality assumption.However,comparison studies to investigate their performances in terms of the accuracy and uncertainty of the estimates are scarce.In addition,the strengths,weakness,and conditions necessary for performing each method also must be investigated.Accordingly,in this study,test experiments with simulations from varying parent distributions and different sample sizes were conducted.Then,applications to the annual maximum rainfall(AMR)time series data in South Korea were performed.Five districts with 38-year(1973–2010)AMR observations were fitted by the three aforementioned methods in the application.From both the experimental and application results,the Bayesian method is found to provide the lowest uncertainty of the design level while the PL estimates generally have the highest accuracy but also the largest uncertainty.The bootstrap estimates are usually inferior to the other two methods,but can perform adequately when the distribution model is not heavy-tailed and the sample size is large.The distribution tail behavior and the sample size are clearly found to affect the estimation accuracy and uncertainty.This study presents a comparative result,which can help researchers make decisions in the context of assessing extreme rainfall uncertainties. | CHEN Si LI YaXing SHIN JiYae KIM TaeWoong | 2016 | Science China(Technological Sciences)2016，59，4： | 4 |

| 4 | 幽门螺杆菌感染与结直肠肿瘤的风险:一项系统综述和荟萃分析显示文摘全世界约有一半人口感染了幽门螺杆菌,幽门螺杆菌感染是消化性溃疡和胃癌等消化道疾病的危险因素。据报道,幽门螺杆菌也与胃癌以外的恶性肿瘤有关,如结直肠肿瘤等。为评估幽门螺杆菌感染与结直肠肿瘤之间的关系,研究者对相关文献进行了系统综述和荟萃分析。通过检索Medline、Embase和Cochrane Library数据库中截至2019年9月发表的关于结直肠腺瘤、进展期结直肠腺瘤、结直肠癌和幽门螺杆菌感染的风险研究,进行荟萃分析。最终48项研究纳入荟萃分析,包括171045例患者,其中24项、8项和31项分别报告了幽门螺杆菌感染与结直肠腺瘤、进展期结直肠腺瘤和结直肠癌的风险。结果显示,幽门螺杆菌感染与结直肠腺瘤的风险显著相关(OR=1.49,95%CI:1.37~1.62);与进展期结直肠腺瘤的风险显著相关(OR=1.50,95%CI:1.28~1.75);也与结直肠癌的风险显著相关(OR=1.39,95%CI:1.27~1.52)。尽管这项基于观察性研究的荟萃分析不能显示因果关系,但它表明,结直肠腺瘤、进展期结直肠腺瘤和结直肠癌都与幽门螺杆菌感染有关。 | Choi DS Seo SI Shin WG 芦波(编译) | 2022 | 中华医学杂志2022，102，22： | 2 |

| 20 | Placement of a fully covered self-expandable metal stent in a young patient with chronic pancreatitis显示文摘Plastic stent insertion is a treatment option for pancreatic duct stricture with chronic pancreatitis.However, recurrent stricture is a limitation after removing the plastic stent.Self-expandable metal stents have long diameters and patency.A metal stent has become an established management option for pancreatic duct stricture caused by malignancy but its use in benign stricture is still controversial.We introduce a young patient who had chronic pancreatitis and underwent several plastic stent insertions due to recurrent pancreatic duct stricture.His symptoms improved after using a fully covered self-expandable metal covered stent and there was no recurrence found at follow-up at the outpatient department. | Kyong Joo Lee Kwang Joon Kim Dong Ho Shin Joo Won Chung Jeong Youp Park Seungmin Bang Seung Woo Park Si Young Song | 2010 | World Journal of Gastrointestinal Endoscopy2010，2，11： | 1 |
