Because of the recent growth in ground-level ozone and increased emission of volatile organic compounds(VOCs),VOC emission control has become a major concern in *** response,emission caps to control VOC have been stipulated in recent policies,but few of them were constrained by the co-control target of pM_(2.5)and ozone,and discussed the factor that influence the emission cap ***,we proposed a framework for quantification of VOC emission caps constrained by targets for pM_(2.5)and ozone via a new response surface modeling(rSM)technique,achieving 50%computational cost savings of the *** the pearl river Delta(prD)region,the VOC emission caps constrained by air quality targets varied greatly with the NOxemission reduction *** control measures in the surrounding areas of the prD region were not considered,there could be two feasible strategies for VOC emission caps to meet air quality targets(160μg/m^(3)for the maximum 8-hr-average 90th-percentile(MDA8-90%)ozone and 25μg/m^(3)for the annual average of pM_(2.5)):a moderate VOC emission cap withreductions or a notable VOC emission cap with>60%NOxemission *** the ozone concentration target were reduced to 155μg/m^(3),deep NOxemission reductions is the only feasible ozone control measure in *** of seasonal VOC emission caps based on the Monte Carlo simulation could allow us to gain higher ozone benefits or greater VOC emission *** VOC emissions were further reduced in autumn,MDA8-90%ozone could be lowered by 0.3-1.5μg/m^(3),equaling the ozone benefits of 10%VOC emission reduction *** method for VOC emission cap quantification and optimization proposed in this study could provide scientific guidance for coordinated control of regional pM_(2.5)and O_(3)pollution in china.

关节软骨是覆盖关节表面的一层承载生物重量的组织。关节软骨在正常状态下,软骨蛋白多糖的弹性和胶原纤维的张力保持平衡。这种平衡的微小变化会引起关节软骨的退化。关节软骨特别是其表层区域的膨胀是和骨关节炎的退化相联系的,定量的测量关节软骨的膨胀可以表征骨关节炎的退化变化。本文的主要目的是介绍一种新的实时超声膨胀测量系统,并把该系统应用到关节软骨的研究中。该系统使用50MHz的超声来实时动态观测用胰岛素和0.15M生理盐水溶液分别浸泡处理的牛膝盖关节软骨的非均匀瞬时深度依赖膨胀行为。实验表明,实时超声检测的方法为关节软骨的退化研究提供了独特的工具。这项技术结合关节内窥镜检查,具有潜在的早期诊断体内关节退化的价值。

总悬浮物(TSM)是水环境评价的重要参数之一,也是遥感水质反演的重要指标。GF-1/WFV和GF-6/WFV作为高分系列对外免费开放的卫星数据,在遥感监测中的应用较为广泛,但目前针对两种数据的对比分析以及GF-6/WFV新增波段在水体水质参数反演中的适用性研究较少。以云南滇池水域为研究区域,对与水体实测数据同步过境(或时相相近)的GF-1/WFV和GF-6/WFV遥感影像采用统计分析的方法进行相同波段(蓝、绿、红、近红外)一致性分析,在此基础上运用经验回归方法分别构建两种数据的TSM反演模型,并将加入GF-6/WFV新增波段的模型与GF-1/WFV构建的模型进行对比分析,选择最优模型应用于滇池2020年的6幅GF-6/WFV图像得到滇池TSM分布图。结果表明:GF-1/WFV与GF-6/WFV的蓝、绿、红、近红外波段的相关系数分别为0.98,0.98,0.97和0.99,两种数据的表观反射率具有很高的一致性。GF-1/WFV基于蓝、绿、近红外波段构建的差值模型“B2+B4-B1”反演精度较高,模型反演的均方根误差为6.35 mg·L^(-1),平均绝对百分比误差为23.60%。GF-6/WFV基于近红外、红边1和红边2波段构建的比值模型“1/B5+B6”反演精度较高,模型反演的均方根误差(rMSE)为3.07 mg·L^(-1),平均绝对百分比误差(MApE)为20.65%,以GF-1/WFV构建的差值模型“B1-B4”与GF-6/WFV构建的“B5-B4”对比发现后者均方根误差减小了2.61 mg·L^(-1),平均绝对百分比降低了32.33%,实验表明加入红边波段的模型反演效果较其他模型更好。采用建模公式得到了2020年滇池TSM分布图,滇池TSM的变化范围在4~45 mg·L^(-1),均值为18.23 mg·L^(-1),总体空间分布呈现北重南轻的分布态势,滇池TSM时间分布表现为上升-下降趋势。该研究不仅可以为湖泊水质监测传感器波段设置提供参考和借鉴,也为滇池水资源监管部门进行水质遥感监测提供了技术支撑。

为了解干湿循环引起的压实黄土强度劣化规律,开展考虑干密度、干湿循环幅度、干湿循环下限含水量三种影响因素的干湿循环三轴试验,得到不同因素影响下的压实黄土强度劣化曲线。采用双曲线函数对劣化度进行拟合,定量分析干密度、干湿循环幅度、干湿循环下限含水量对压实黄土强度劣化规律的影响,建立综合考虑三种影响因素的“压实黄土干湿循环强度劣化模型(CLDM)”,并通过SEM图像分析从微观结构角度对强度劣化进行解释。最终通过基于python语言的二次开发将CLDM模型应用至有限元软件ABAQUS,实现了干湿循环作用下压实黄土填方边坡稳定分析,验证了CLDM模型在数值模拟中的适用性。研究结论可为压实黄土干湿循环强度劣化的分析以及填方边坡灾害预测提供参考。

中等挥发性有机物(Intermediate Volatility Organic Compounds,IVOCs)是二次有机气溶胶(SOA)的重要前体物.然而,当前我国IVOCs排放清单研究相对较少,现有研究大多采用基于IVOCs/pOA比值法估算,导致IVOCs排放表征存在很高的不确定性.以移动源为研究对象,在优先采用本土实测的排放因子的基础上,构建了基于实测排放因子的广东省2019年移动源IVOCs排放清单,并与基于IVOCs/pOA比值法建立的排放清单进行对比评估.结果显示:2019年广东省移动源IVOCs总排放量为2.1万t,其中,道路移动源IVOCs排放量为1.5万t,占总排放量的70%,主要来自柴油重货(33%)、柴油轻货(23%)、汽油小客(14%).其中,道路移动源IVOCs汽油车主要以国四、国五标准车型为主,分别占汽油车排放的36%和49%,而柴油车主要以国三、国四标准车型为主,分别占柴油车排放的53%和28%.相比实测因子法,比值法计算的道路移动源IVOCs排放整体偏高了100%~200%,但计算的非道路移动源IVOCs排放整体偏低了近1/3.通过不确定性量化对比也发现,实测因子法建立的IVOCs排放清单不确定性整体比比值法平均降低了60%,表明实测排放因子能够提高IVOCs表征的可靠性.此外,本土和国外实测排放因子建立的道路移动源IVOCs排放也有明显差异,采用国外实测排放因子可能会导致广东省2019年道路移动源IVOCs排放低估30%~50%.
