The region along the Taihang Mountains in the North China Plain(NCP) is characterized by serious fine particle pollution. To clarify the formation mechanism and controlling factors, an observational study was conducted to investigate the physical and chemical properties of the fine particulate matter in Jiaozuo city, China. Mass concentrations of the water-soluble ions(WSIs) in PM_(2.5) and gaseous pollutant precursors were measured on an hourly basis from December 1, 2017, to February 27, 2018. The positive matrix factorization(PMF) method and the FLEXible PARTicle(FLEXPART) model were employed to identify the sources of PM_(2.5). The results showed that the average mass concentration of PM_(2.5) was 111 μg/m^(3) during the observation period. Among the major WSIs, sulfate, nitrate, and ammonium(SNA) constituted 62% of the total PM_(2.5) mass, and NO_(3)^(-) ranked the highest with an average contribution of 24.6%. NH_(4)^(+) was abundant in most cases in Jiaozuo. According to chemical balance analysis, SO_(2)-4, NO_(3)^(-), and Cl^(-) might be present in the form of(NH_4)_(2)SO_4, NH_4NO_3, NH_4Cl, and KCl. The liquid-phase oxidation of SO_(2) and NO_(2) was severe during the haze period. The relative humidity and pH were the key factors influencing SO_(4)^(2-) formation. We found that NO_(3)^(-) mainly stemmed from homogeneous gas-phase reactions in the daytime and originated from the hydrolysis of N_(2)O_5 in the nighttime, which was inconsistent with previous studies. The PMF model identified five sources of PM_(2.5) : secondary origin(37.8%), vehicular emissions(34.7%), biomass burning(11.5%), coal combustion(9.4%), and crustal dust(6.6%).

欧亚主义是20世纪20年代出现于俄侨知识分子阶层的一种思想潮流,它从自然—地理前提出发,广延至历史、文化、经济、政治、文学及宗教等诸多领域。欧亚主义者根植于本国土壤,强调俄罗斯的独特性,先后提出许多颇有见地的思想和主张,积极为转型中的俄罗斯发展探求道路。在同期文学创作中,欧亚主义思想亦有萌生和书写。我们在梳理该思想产生的社会背景、理论渊源及核心内容基础上,着重分析维·伊万诺夫、勃洛克、别雷以及阿·托尔斯泰、皮里尼亚克、普拉东诺夫等作家创作中的欧亚主义观念。借助"东方与西方"、"民族与世界"、"传统与现代"等主题,诠释欧亚主义思想与文学创作的相互丰富作用。欧亚主义是俄罗斯民族意识增强的一种彰显,亦是俄罗斯思想发展的一个不可或缺的重要环节。
