As a major source of air pollution in urban areas, the motor vehicle exhaust has attracted more and more attention due to its growing amount and serious harm to human health. It is of benefit to the pollutant control to make clear the transportation characteristics of vehicle exhausts. In this paper, the transportation characteristics of vehicle exhaust pollutants are investigated by means of the on-site measurement based on a typical Beijing expressway-Badaling expressway （G6 state expressway）. The concentrations of CO, NOx, S02 and particles near the expressway were obtained, by which the variations of the particle num- ber and mass concentrations, as well as the gas pollutant volume concentrations in the vicinity of the roadways with the dis- tance from the expressway were fitted. The results show that the gas pollutant concentrations and particle concentrations de- crease almost exponentially with the distance from the expressway, which is helpful for the air pollutant database establish- ment and future pollution control in big cities.

As important precursors of ozone(O_(3))and secondary organic aerosol(SOA),reactive aromatic hydrocarbons(AHs)have typically been classified as anthropogenic air ***,biogenic emission can also be a potential source of atmospheric ***,field observations in a eutrophic lake were combined with laboratory incubation experiments to investigate the biogenic AH *** work showed that the water-air fluxes of AHs measured at sites with high cyanobacteria abundance could reach an order of magnitude greater than those at sites with low cyanobacteria abundance,suggesting that cyanobacteria could be the important contributor to measured *** incubation experiments further confirmed the AH emission of cyanobacteria and revealed that the emission could change significantly over the lifespan of cyanobacteria and varied to their growing *** combining field observations and laboratory incubation experiments,it has been suggested that the emission of different AH species from cyanobacteria could be modulated by variable biogeochemical mechanisms and that the biochemical process of toluene could be different from that of other *** study investigates AH emissions from inland aquatic ecosystem and suggests that biogenic emission could be a potential source of atmospheric AHs.

Nitrogen-containing organic compounds(NOCs)may potentially contribute to aqueous secondary organic aerosols,yet the different formation of NOCs in aerosol particles and cloud droplets remains *** the in-situ measurements performed at a mountain site(1690 m a.s.l.)in southern China,we investigated the formation of NOCs in the cloud droplets and the cloud-free particles,based on their mixing state information of NOCscontaining particles by single particle mass *** relative abundance of NOCs in the cloud-free particles was significantly higher than those in cloud residual(cloud RES)*** were highly correlated with carbonyl compounds(including glyoxalate and methylglyoxal)in the cloud-free particles,however,limited correlation was observed for cloud RES *** of their mixing state and temporal variations highlights that NOCs was mainly formed from the carbonyl compounds and ammonium in the cloud-free particles,rather than in the cloud RES *** results support that the formation of NOCs from carbonyl compounds is facilitated in concentrated solutions in wet aerosols,rather than cloud *** addition,we have identified the transport of biomass burning particles that facilitate the formation of NOCs,and that the observed NOCs is most likely contributed to the light *** findings have implications for the evaluation of NOCs formation and their contribution to light absorption.

基于一套冷模填料塔晃动试验装置研究海上晃动工况对填料塔流体分布性能的影响。根据横摇、纵摇、横荡、纵荡、垂荡、艏摇6个单自由度晃动试验结果,分析筛选出对流体分布性能影响较大的晃动形式。以此为基础两两相互耦合得到两自由度耦合晃动工况。再通过分析塔出口截面处的整体流量分布、环形流量分布、径向流量分布、壁流量分布试验指标,得出两自由度耦合晃动条件下填料塔流体分布规律。结果表明,摇摆及摇摆+摇摆的耦合晃动工况对液体的流动性能影响较大,并且随着晃动幅度增加,流体不均匀性增大。平荡对于液体流动性能的影响较小。

共同富裕是社会主义的本质要求。社工站建设也已成为夯实基层民政力量、推动基层治理现代化、增进人民福祉的重要举措,其价值理念与共同富裕的目标相一致,任务相契合。共同富裕的丰富内涵与社工站建设的目标导向明确了社工站协同推动者、福利传递者、服务提供者、资源链接者的角色定位。然而,在社工站现实作用发挥过程中,其面临着政社关系与资源牵制、福利输送表象化、服务成效短暂以及力量薄弱联动困难等诸多问题。为此,应着力构建合作型政社关系,加快福利理念传递与服务提升,不断完善考核机制,促进专业服务提质增效,积极营造共建共享的社会氛围,合力助推共同富裕。
