受气候变暖影响,东北北部地区冻融灾害频发,对寒区工程设施造成了重要影响。地基温度场的研究是分析与解决工程基础冻融灾害的重要手段。文中我们以漠河机场跑道为对象,通过有限单元法研究了洁净砾石换填对机场道基温度场的影响,并对运行30年内道基温度场进行预测。结果表明,换填使季节最大冻结深度(MSF)增加,且换填对道基下MSF的水平影响范围在道面中心线两侧30 m左右。之后,通过比较不同换填深度(1.5(顶)~3.5(底)、1.5~4.5、1.5~5.5和1.5~6.5 m)的道基温度场变化,发现:换填底部深度达到4.5 m时,MSF变化的速率开始减小。最后,根据IPCC第六次评估报告(AR6)未来100年间不同气候变暖速率模型模拟研究了无换填与不同换填深度下的MSF可能变化。结果发现,到2100年,在SSP2-4.5情景下,未换填及不同换填深度的道基下MSF分别为1.63、1.86、1.84、1.84和1.84 m。因此,利用换填法来减少跑道冻融灾害时换填深度应至少达到4.5 m。同时,应加强漠河机场道基地表水与该跑道区地下水的防排水设施建设与维运。研究结果有助于进一步认识换填对多年冻土和活动层水热状态的影响,可为解决道基冻胀和融沉问题提供重要科学依据。

作者： DING Han-ming zhang Da-wei LI jiang KONG Ai-guo SHAN Yong-kui Department of Chemistry East China Normal University Shanghai 200062 P. R. China

A new titanium-silicate material was synthesized with cubic cage-like tetramethylammonium octasilicate and TiCl4 ethanol solution as precursors. The product was characterized by FTIR, ^29Si NMR, UV-Vis, and XRD. Struc-tural and ingrediental analyses suggest that this material has a layered structure with cubic cage-like polyhedral oligo-silsesquioxane as building blocks and titanium as bridging atoms.

Elevated Arsenic Exposure Is Associated with an Increased Risk of Chronic Hepatitis B Virus Infection： NHANES （2003-2014） in U.S. Adults

Current Medical Science 2018年第4期38卷 610-617页

作者： wei-hua zhang jiao HUANG Mei FENG Ye-qing TONG Xu-hua GUAN Hong-wei jiang Sheng wei Department of Epidemiology and Biostatistics Key Laboratory of Environment and Health of Ministry of Education School of Public Health Tongji Medical College Huazhong University of Science and Technology Wuhan 430030 China Department of Preventive Medicine School of Medicine Ningbo University Ningbo 315211 China Institute of Infectious Disease Control and Prevention Hubei Provincial Center for Disease Control and Prevention Wuhan 430079 China

Studies concerning the association between arsenic exposure and hepatitis B virus （HBV） infection have been lacking. The present study aimed to examine the association between total urinary arsenic （TUA） and infection ofHBV. A total of 5186 participants from National Health and Nutrition Examination Survey （NHANES） 2003-2014 were included in the analysis. We used logistic regression to evaluate the association. We defined two measures of TUA. TUA1 was the sum of arsenous acid, arsenicacid, monomethylarsonic acid and dimethylarsenic acid. TUA2 was defined as TUA minus arsenobetaine and arsenocholine. The results showed that the weighted overall prevalence of HBV infection was 6.08%. For NHANES 2003-2014, the medians （interquartile range） of TUA1 and TUA2 were 5.60 μg/L （3.97-8.09 μg/L） and 4.91 μg/L （2.36-9.11 μg/L）, respectively. Comparing the highest quartile to the lowest quartile after multivariable adjustment showed that the odds ratios （ORs） and 95% confidence intervals （CIs） for TUA1 and TUA2 were 2.44 （1.40-4.27） and 2.84 （1.60-5.05）, respectively. In conclusion, elevated urinary arsenic was associated with the risk of HBV infection. Further studies, especially prospective studies, are needed to confirm the causal relationship between arsenic exposure and HBV infection.
