The selection of a suitable discretization method(DM)to discretize spatially continuous variables(SCVs)is critical in ML-based natural hazard susceptibility assessment.However,few studies start to consider the influence due to the selected DMs and how to
Bangladesh experiences frequent hydro-climatic disasters such as flooding.These disasters are believed to be associated with land use changes and climate variability.However,identifying the factors that lead to flooding is challenging.This study mapped fl
目的探讨木犀草素对哮喘大鼠气道炎症的影响机制。方法SPF级雄性SD大鼠48只，用随机数字表法随机平均分为对照组、哮喘组、木犀草素组3组：哮喘组、木犀草素组复制大鼠哮喘模型，即在第1、8天腹腔注射卵白蛋白/氢氧化铝混合液，2周后以1%的卵白蛋白生理盐水溶液雾化激发，每周3次，持续8周。对照组参照上述方法，但以生理盐水代替卵白蛋白/氢氧化铝混合液及卵白蛋白生理盐水。每次激发后30 min，对照组与哮喘
茹尔群岛(又称赖于尔群岛)位于东南极普里兹构造带的东部边缘,是一个由太古宙和中元古代岩石组成的复合高级变质地体.中元古代岩石是含有富Fe-Al的含石榴子石-矽线石的费拉副片麻岩组合,经历了格林维尔和泛非两期变质作用.太古宙正片麻岩是含有富Mg-Al的含假蓝宝石的超高温泥质麻粒岩组合(梅瑟副片麻岩组合),主要由经历超高温变质作用的含假蓝宝石的泥质麻粒岩、 富Mg的石榴子石-矽线石泥质片麻岩、 斜方辉石-矽线石石英岩、 含石榴子石镁铁质麻粒岩和钙硅酸盐麻粒岩等组成.其中,含假蓝宝石泥质麻粒岩中石榴子石变斑晶和
In China\'s Loess Plateau severe gully erosion(LPGE)region,the shoulder-line is the most intuitive and unique manifestation of the loess landform,which divides a landform into positive and negative terrains(PNTs).The spatial combination model of PNTs is
目的探讨双源CT及其后处理技术在急性肺动脉栓塞诊断中应用价值。方法收集滨州医学院附属医院2011年10月至2013年5月收治20例可疑肺栓塞患者，进行双源CT扫描，应用3D软件、肺血管分析软件(lung vessels)、肺栓塞分析软件(PED)以及lung PBV软件对扫描图像进行分析，探索肺动脉成像(CTPA)、lung vessels、PED对肺栓塞检出率差异有无统计学意义，筛选对肺段肺栓塞
Crushing and embedment are two critical downhole proppant degradation mechanisms that lead to a significant drop in production outputs in unconventional oil/gas stimulation projects.These persistent production drops due to the non-linear responses of prop
极地地区 (南极和北极) 具有独特的地理位置、 地质地貌和生态环境, 是研究地球演化过程和认识全球海陆构造格局不可或缺的重要一环, 但也是全球地学研究的最薄弱区域. 南极是被大洋围陷的大陆,它是地球上最古老的大陆之一, 经历并保存了地球形成和演化过程中一些重大地质事件的记录, 包括太古宙古陆核的形成、 古元古代造山事件、 格林维尔期 (～10亿年) 构造热事件、 泛非期 (～5亿年) 构造热事件以及显生宙大陆边缘增生与陆块分离, 因此是研究全球超大陆聚散过程的重要基石.
The Yubei-Tangbei area in the southern Tarim Basin is one of the best-preserved Early Paleozoic northeast-southwest trending fold-and-thrust belts within this basin.This area is crucial for the exploration of primary hydrocarbon reservoirs in northwestern
The Sichuan-Yunnan-Guizhou(SYG)Zn-Pb metallogenic zone in SW China contains＞400 carbonate-hosted hydrothermal Zn-Pb deposits.Some of these,such as the Huize,Tianbaoshan,and Daliangzi deposits,are super-large deposits with significant reserves of Cd,Ge,and
