As a representative of non-evaporative getter,Zr-V-Fe has gained widespread attention due to its advantages including low activation temperatures and rapid hydrogen absorption *** this study,we investigated the impact of La and Ce doping on the thermodynamic,kinetic,and activation properties of Zr_(7)V_(5)Fe alloy.x-ray diffraction analysis shows that rare earth doping causes a decrease in the cell volume of both the ZrV_(2) andα-Zr phases of Zr_(7)V_(5)Fe alloy,which results in an increase in the plateau pressure of the *** kinetic curves illustrate that rare earth doping leads to a coarseα-Zr phases and a larger particle size after activation,resulting in a decrease in the hydrogen absorption kinetic *** for the activation process,the rare earth doped alloys exhibit excellent activation with shorter incubation periods.x-ray photoelectron spectroscopy investigations reveal that Zr and V are initially in a highly oxidized *** the heating temperature increases,they undergo a transition from oxidation state to metal *** content of metal Zr in rare earth doped alloys is higher than that in undoped alloys at 250℃,primarily due to rare earth elements'affinity for oxygen.

Size-fractionated particulate matter(PM_(2.5)and PM>_(2.5))was collected at a traffic site in Kanazawa,japan in a seasonal sampling work in *** polycyclic aromatic hydrocarbons(4-to 6-ring PAHs)were determined in fine and coarse *** gas/particle partitioning coefficients(K_(p))of the PAHs were calculated from the supercooled liquid vapour pressure and octanol-air partitioning coefficient based on the relationships obtained in previous traffic pollution-related *** PAHs were estimated by K_(p) and the concentrations of PM and particulate *** concentrations of total PAHs were 32.5,320.1 and 5646.2 pg/m^(3) in the PM>_(2.5),PM_(2.5) and gas phases,*** seasonal trends in PAHs were observed(particle phase:lowest in summer,gas phase:lowest in spring,particle and gas phase:lowest in spring).Compared to 2019,the total PAH concentrations(in particles)decreased in 2020,especially in spring and summer,which might be due to reduced traffic trips during the COVID-19 *** incremental lifetime cancer risk(ILCR)calculated from the toxic equivalent concentrations relative to benzo[a]pyrene(BaP_(eq))was lower than the acceptable limit issued by the US Environmental Protection Agency,indicating a low cancer risk in long-term exposure to current PAH *** is notable that gaseous PAHs considerably contributed to BaP_(eq) and ILCR(over 50%),which highlighted the significance of gaseous PAH monitoring for public health *** low-cost estimation method for gaseous PAHs can be expected to reliably and conveniently obtain PAH concentrations as a surrogate for traditional sampling in the future work.

为降低火灾环境对消防员皮肤烧伤的危害,构建空气层三维传热模拟装置,模拟服装开口处的衣下空气层状态,并开展低热辐射条件下的热暴露试验,探究着装人体与外界环境的热量交换及对人体皮肤热防护的影响规律。结果表明:与封闭空气层相比,开放空气层条件下织物受热面的峰值温度更低;空气层厚度的增加和边界的开放能够提升织物系统的热防护能力;3 mm空气层条件下,封闭状态的热防护性能更好,而其它厚度下开放空气层的防护能力更好;与无空气层条件相比,3~18 mm的封闭空气层可将热流密度衰减提升16.2%~44.5%、皮肤温度降低9%~26.7%、二级烧伤时间延长10.0%~100.8%;开放空气层可将热流密度衰减提升8.0%~50.7%、皮肤温度降低4.7%~30.0%、二级烧伤时间延长7.2%~140.9%。

魏晋南北朝文学中取法、援用和咏写地图的特出时代现象,顺应了汉末以降史学及其附属的地理学不断成长的学术发展态势。地图作为其时史部地理类文献中主要且特殊之一种,融时间与空间、图像与文字、技术与艺术于一炉,不唯与历史地理学密不可分,同时也与都邑、山水、行旅等诸多文学题材息息相关。这一时段内,有关文学展示出的地图影响特点表现在:首先,地图绘制的理念、元素、方法,不时渗入文学作品的书写模式、内容形态、语言体制中;其次,地图承载着的真确、精博的图文资料,屡屡构成文学创作的知识来源和校核依据,催生了一股崇真尚实的文风潜流。在技术和工具层面之外,地图蕴含的美学属性和象征寓意,还能唤起文人的阅读想象力,故此将地图用于审美和隐喻思维的表达,丰富和增进了文学的表现力。上述因地图之制作、观览与想象所造成的三重影响,使其在汉唐之间的文学演进过程中扮演了重要的角色。
