鹼金属钾、钠的微量测定,近来常用的是火焰光度法,而且火焰光度法也几乎是唯一的一种比较准确的方法,但是这种仪器设备目前还不算普遍,因此寻找其他比较简单的测定方法还是有必要的。 1948年,Fisher,Parsons和Morrison从氨基酸的纸上色层分离实验中,证明了一条非常重要的规律,即:“色层谱斑点面积与氨基酸溶液的原始浓度的对数成直线关系”。1949年,Brimley.用热传导和扩散的理论说明了这条规律。如果以S代表斑点面积,C代表未知物原始浓度,则得下列数学关系式:

Effects of the urban landscape on heatwave-mortality.associations in Hong Kong: comparison of different heatwave definitions

引用

Frontiers of Environmental Science & Engineering 2024年第1期18卷 145-156页

作者： Jinglu Song y. lu Thomas Fischer Kejia Hu Department of Urban Planning and Design Xi’an Jiaotong-Liverpool UniversitySuzhou 215123China Department of Architecture and Civil Engineering City University of Hong KongKowloon TongHong Kong 999077China Environmental Assessment and Management Research Centre School of Environmental SciencesUniversity of LiverpoolLiverpool L35TRUK Research Unit for Environmental Sciences and Management Faculty of Natural and Agricultural SciencesNorth West UniversityPotchefstroom 31750South Africa Institute of Big Data in Health Science School of Public HealthZhejiang UniversityZijingang CampusHangzhou 310058China

Despite increased attention given to potential modifiers of temperature-mortality.associations, evidence for variations between different urban landscape characteristics remains limited. It is in this context that in this paper effect modifications of multiple urban landscape characteristics are explored under different heatwave definitions for different age groups and gender in Hong Kong, China. Daily.meteorological data and heatwave-related mortality.counts from 2008 to 2017 were collected from the Hong Kong Census and Statistics Department, China. A case-only.design was adopted, combined with logistic regression models to examine the modification effects of five urban landscape characteristics under six heatwave definitions. Stratified analy.es were conducted to investigate age- and gender-specific effect modifications. It is found that individuals living in greener areas experienced lower levels of mortality.during or immediately.after heatwaves. In contrast, a higher building density.and nighttime land surface temperature (LST) were associated with a higher heatwave-related mortality.risk. Pronounced effect modifications of these urban landscape characteristics were observed under hotter and longer heatwaves, and in older adults (age ≥ 65 y.ars) and males. The findings provide a scientific basis for policy.akers and practitioners when considering measures for coping with hotter, longer, and more frequent heatwaves in the context of global climate change.

Exploring the impacts of major events on the sy.temic risk of the international energy.market

Petroleum Science 2024年第2期21卷 1444-1457页

This study.examines the sy.temic risk caused by.major events in the international energy.market(IEM)and proposes a management strategy.to mitigate it. Using the tail-event driven network(TENET)method, this study.constructed a tail-risk spillover network(TRSN) of IEM and simulated the dy.amic spillover tail-risk process through the cascading failure mechanism. The study.found that renewable energy.markets contributed more to sy.temic risk during the Paris Agreement and the COVID-19pandemic, while fossil energy.markets play.d a larger role during the Russia-Ukraine conflict. This study.identifies sy.temically.important markets(SM) and critical tail-risk spillover paths as potential sources of sy.temic risk. The research confirms that cutting off the IEM risk spillover path can greatly.reduce sy.temic risk and the influence of SM. This study.offers insights into the management of sy.temic risk in IEM and provides policy.recommendations to reduce the impact of shock events.
