We obtain several estimates of the essential norms of the products of differen- tiation operators and weighted composition operators between weighted Banach spaces of analytic functions with general weights. As applications, we also give estimates of the es- sential norms of weighted composition operators between weighted Banach space of analytic functions and Bloch-type spaces.

农村题材电视剧在我国独具特色并展现出特有的社会功能,其中,《乡村爱情》系列电视剧颇具代表性。以该系列电视剧作为研究对象,结合内容分析与叙事分析方法,可探讨该剧获得成功的多维因素,并可对该剧建构的乡村文化景观进行分析。该剧突出了农村题材电视剧的乡村形象建构与振兴政策宣导的功能,积极表现乡村现代化发展与乡村治理困境;但在市场化过程中,尤其自"弃台从网"等策略开始后,该剧自身的现实主义色彩又有所减弱,甚至一定程度上固化了某种农村形象。未来的相关影视剧创作应运用艺术语言描绘乡村振兴的伟大成果,探索出更多的优秀主旋律作品。

监测了北京市某A^(2)O工艺污水处理厂不同工艺段逸散出的微生物气溶胶的浓度和粒径分布情况,统计了各工艺段所有采集样本污染程度和可吸入颗粒占比,分析了影响各工艺段微生物气溶胶浓度和可吸入颗粒数变化的因素.同时,计算了各工艺段暴露风险值,判断微生物气溶胶对不同人群的危害性.结果表明,各工艺段微生物气溶胶均有不同程度的释放,浓度变化范围在107~37139 CFU·m^(-3)之间,其中,生物池释放浓度最低,为107~624 CFU·m^(-3),一直处于清洁等级;板框脱水间释放浓度最高,为3329~37139 CFU·m^(-3),粉尘颗粒较多是造成板框脱水间微生物气溶胶浓度极高的重要原因.各工艺段可吸入颗粒(1),需引起重视.
