    随着居民经济收入的提升,传统的体检服务已经不能满足消费者深层次的需求,催生了体检旅游产业。消费者不断追求健康检查与旅游需求的双重满足,且需求量在不断增长。厦门作为一个旅游大城市和区域性医疗服务中心,具有丰富的旅游资源和提供体检旅游的服务能力,但其体检旅游产业发展水平仍相对落后。因此,在国内外都缺乏对体检旅游消费者需求及消费行为等详实分析的情形下,有必要加强对体检旅游产业的调查与研究,以帮助厦门提升与推广体检旅游业。 基于上述,本文通过综合国内外研究,对医疗旅游、体检旅游以及体检旅游消费行为等概念进行了界定,以某专业体检中心的消费群体——体检旅游者为对象;以消费者心理影响理论、消费者需求层次理...With the improvement of the residents' economic income, the traditional physical examination service has been unable to meet the deep-seated needs of consumers, gave birth to the medical tourism industry.

    搜寻X射线双星并建立大规模样本是解决众多科学问题(如\"银河系中有多少黑洞X射线双星?黑洞和中子星之间有无质量间隙?球状星团中有无黑洞?\"等)的基础.爱因斯坦探针卫星拥有更灵敏的探测能力,将在运行的几年之中,预计可以发现一批新的中子星和黑洞X射线双星,研究其空间和动力学质量分布成为解决上述问题的关键.国家重点研发计划(编号:2016YFA040080X);;国家自然科学基金(编号:1133305);;中国科学院战略性先导科技专项(编号:XDA15052100,XDB23040000)资助项

    Phenanthrene sorption by sediments from Yellow River Estuary: Effects of environmental factors

    To understand the environmental behaviors and ecological risks of polycyclic aromatic hydrocarbons(PAHs)in the transport processes from the river to the estuary, and subsequently coastal waters, the sorption of phenanthrene on the Yellow River estuary sediments was investigated under varying conditions including sediment concentrations, dissolved organic matter(DOM), temperature, and salinity. Phenanthrene sorption by estuarine sediments and marine sediments were also compared. The results showed that sediments with low concentration exhibited high sorption capacity for phenanthrene. Phenanthrene sorption was enhanced in the presence of DOM, and the effect of humic acid(HA)was more significant than that of fulvic acid(FA). The sorption capacity declined with increasing temperature, whereas it increased with increasing salinity. Surface adsorption and partitioning of phenanthrene occur simultaneously on the sediments. For estuarine sediments, adsorption was predominant, while partitioning was the main mechanism for marine sediments. Moreover, the sorption capacity of marine sediments was higher than that of estuarine sediments. Based on these results, it can be concluded that phenanthrene is inclined to be adsorbed on sediments in the transport processes from the river to the estuary, and subsequently coastal waters, which may reduce the ecological damage in water, but raise the potential health risks to benthonic organisms in offshore marine areas

    为了加深对地面覆盖措施保墒增产机理的认识,通过大田试验,对黄土高原南部旱塬区秸秆和地膜两种覆盖方式下玉米农田土壤水分动态、作物产量形成和水分利用效率进行了分析。结果表明:在试验年份,与不覆盖相比,秸秆覆盖后玉米生育期内土壤储水量提高了5.2%~8.4%(P<0.05),籽粒产量和水分利用效率分别降低了7.8%和3.5%;而地膜覆盖下土壤储水量的差异不显著,但显著提高了产量构成指标,其籽粒产量和水分利用效率分别较对照提高了14.1%和10.6%(P<0.05),显示后者抑制土表蒸发所增加的土壤水分更多地、更有效地被作物根系吸收利用了。从产量形成和水分利用效率角度分析,本地区旱作玉米农田使用地膜覆盖有较好的保墒增产效果。Abstract:To understand the mechanisms of soil moisture conservation and crop yield increasing by soil surfacemulching deeply,soil water dynamic,crop yield formation and water use efficiency in a corn field under strawmulching and plastic film mulching were studied by a field experiment conducted in the dryland of the southern Loess Plateau.In the years of the experiment,compared with the contrast without mulching,soil waterstorage under straw mulching treatment in corn growth stage increased by 5.2%~8.4% (P<0.05)andgrain yield and water use efficiency under straw mulching treatment decreased by 7.8%and 3.5%,respectively.The difference of soil water storage induced by plastic film mulching was not significant,but plasticfilm mulching remarkably raised yield formation index and increased grain yield and water use efficiency by14.1%and 10.6%over the contrast(P<0.05),respectively.This suggests that the soil moisture incrementby the inhibition of plastic film mulching on soil surface evaporation was absorbed by crop roots,more largely and more effectively.In terms of yield formation and water use efficiency,the adoption of plastic filmmulching in dry-farming corn fields of the region may induce better effects of soil moisture conservation andcrop yield increasin

    采用分步浸渍法制备了NiO/α-Al2O3、NiO—CuO/α-Al2O3和NiO-La2O3/α-Al2O3三种催化剂,运用程序升温表面反应(TPSR)技术考察了助剂CuO和La2O3对NiO/α-Al2O3甲烷催化部分氧化(CPOM)反应引发过程的影响。结果表明,无论是否经过预还原处理,NiO/α-Al2O3催化剂在CH4/O2混合气氛下进行程序升温表面反应(CH4/O2-TPSR)时,即使升高到910oC也不能引发CPOM反应。添加助剂CuO或La2O3后,NiO—CuO/α-Al2O3和NiO—La2O3/α-Al2O3催化剂在CH4/O2-TPSR过程中均可以引发CPOM反应。原因分别是CuO促进了CH4对NiO的还原以及抑制了O2对Ni^0的再氧化,La2O3减小了Ni晶粒粒径和还原时扩散阻力促进NiO的还原
