Shijiazhuang is one of the cities in the North China *** recent decades,this city has experienced high levels of fine particulate matter(PM_(2.5)),which have potentially significant effects on human *** this study,the health effects of PM_(2.5)exposure in Shijiazhuang were estimated by applying an integrated exposure-response *** mortality,years of life lost(YLL),and the mortality benefits linked to reduced levels of PM_(2.5)were quantified for the period 2015–*** 2015,2016,and 2017,cerebrovascular diseases caused the highest premature mortality(2432,2449,and 2483,respectively),followed by ischemic heart diseases(1391,1479,and 1493,respectively),lung cancer(639,660,and 639,respectively),and chronic obstructive pulmonary diseases(533,519,and 473,respectively).Notably,the total number of premature deaths caused by PM_(2.5)exposure in Shijiazhuang in 2015,2016,and 2017 were 4994,5107,and 5088,***,the YLL in the same years were 47001,47880 and 47381,***,the YLL per 1000 females was lower than that per 1000 ***,we noted that premature mortality and YLL decreased by 84.2%and 84.6%when the PM_(2.5)levels diminished to 10µg/m^(3).Overall,the results of this study improve our understanding of how high PM_(2.5)concentrations affect human health and suggest the application of more stringent measures in Shijiazhuang to alleviate the associated health risks.

价值观的形成与发展离不开具体的媒介环境。文章从媒介的演进考察各时期价值观引导的特征,并认为,由媒介的变革引发了价值观引导的变迁,其积极的影响表现为公共媒介的公共文化传播、从媒介主体到自我主体的证验和从面对媒介到面对人的回归,其消极的影响表现为持久与扩张的错位、去中心化以及价值观的"看"僭越了价值观的"读"。由此,文章认为,在当代媒介环境下价值观的引导应当加强媒介素养教育和媒介规制,培养读与思、听与说的书面、口语传统习惯。

水平井凭借其独有的技术和经济优势,已成为高效开发致密气藏的关键技术,但是其在非层状气藏的开发中却效果较差。为此,针对鄂尔多斯盆地苏里格气田二叠系下石盒子组8段含气砂体孤立分散的分布特点,采用露头类比、地质统计、密井网先导试验3种方法研究了该气田含气砂体的展布方向及规模特征,结合密集井网区精细地质解剖成果,提出了4种适用于该气田盒8段部署水平井的含气砂体分布样式：①厚层块状孤立型;②具物性夹层的垂向叠置型;③具泥质夹层的垂向叠置型;④横向串糖葫芦型。统计当前已实施水平井钻遇含气砂体的情况,发现所钻遇的含气砂体长度多数分布在670~1300 m。以苏X区SuX-18-36典型井组的物性夹层垂向叠置型砂体为例,结合生产数据修正法、数值模拟法及经济评价法,优化了气田合理水平段长度,认为在当前经济技术条件下,1200 m以内的水平段长度适合于该气田的该类叠置样式的砂体。该成果为该气田的后续高效开发提供了技术支撑。

在应用于工程装备的混合动力交直交电驱系统中,永磁同步电机在进行再生制动时往往回馈过量的电功率至直流母线上,容易引起直流母线电压泵升,影响发动/发电机组的运行性能.为解决该问题,从电机制动时逆变器和储能系统双向DC/DC占空比匹配不一致的角度分析母线电压泵升的原因,在此基础上提出了一种在传统逆变器双闭环矢量控制的转速外环上添加前馈补偿的控制策略,通过将直流母线电压与其参考值的误差进行比例-微分调节,并利用其输出的补偿量作为下垂因子作用于q轴电流给定值上,减小电机制动阶段的转矩电流和逆变器的占空比,限制电机回馈的电功率.仿真结果表明,该控制策略能有效改善混合动力电驱系统电机制动阶段母线电压泵升的问题,能较好地保护母线电气安全.
