Photocatalytic aerobic oxidation reactions are largely governed by the efficiency of charge separation and subsequent reactive oxygen species(ROS) generation. Herein, we report a polarization engineering strategy to promote the charge separation and ROS generation efficiency by substituting the benzene unit with furan/thiophene in porous organic polymers(POPs). Benefiting from the extent of local polarization, the thiophene-containing POP(JNU-218) exhibits the best photocatalytic performance in aerobic oxidation reactions, with a yield much higher than those for the furan-containing POP(JNU-217) and the benzenecontaining POP(JNU-216). Experimental studies and theoretical calculations reveal that the increase of local polarization can indeed reduce the exciton binding energy, and therefore facilitate the separation of electron-hole pairs. This work demonstrates a viable strategy to tune charge separation and ROS generation efficiency by modulating the dipole moments of the building blocks in porous polymeric organic semiconductors.

为探究富春江水库浮游植物群落结构的演替特征、水华风险机制及关键影响因素,分别于2020年8月和11月与2021年1月和4月在富春江库区及上下游11个断面采样分析浮游植物、浮游动物群落结构及相关理化指标,对浮游植物进行功能群(FG)分类,并应用非度量多维尺度分析(NMDS)和冗余分析(RDA)等统计方法探讨功能群变化的影响因素.结果发现,富春江水库浮游植物可分为18个功能类群,其中10个为优势类群;功能群的组成存在显著时空差异:空间上,库区上游江段主要以小环藻(Cyclotella)为代表的C类群和以沟链藻(Aulacoseira)为代表的P类群占优,与该江段中富营养混合水体的环境特征相符;富春江库区仍以P类群为主,但沿程优势度逐渐减小;库区下游江段MP类群逐渐占优,且在钱塘江口占据绝对优势,反映了感潮河流扰动频繁、浊度较高的环境特征;季节上,夏季功能群类型最为丰富,为P+L0+J+M+S1+H1+MP型,除了全年都占优的沟链藻为代表的P类群,还包括多个以蓝藻和绿藻为代表的类群,反映出生境多变、生产力旺盛的水环境特征;秋季演替以长孢藻(Dolichospermum)为代表的H1类群占优,总体为P+H1,反映了水量减少、流态趋于静止的水环境特征;冬季小环藻的突增,C类群占据优势,总体为P+C,反映出换水减弱、富营养化加剧的环境条件变化;而春季类群又逐渐丰富,为C+D+P+MP,也反映出降雨增多、气温升高引起的河流生境多变的环境背景特征.根据C-R-S生长策略分析,R策略类群是富春江水库浮游植物的主导类群,与富春江流域各江段高干扰、低胁迫的总体生境特征吻合.RDA分析表明,水温、浮游动物生物量、高锰酸盐指数、流量、总氮和总磷与浮游植物功能群组成显著相关(P<0.05),温度和流态是影响富春江水库浮游植物功能群时空差异的主导因素,浮游动物是影响浮游植物功能群时空差异的关键因素.研究表明,水文气象过程对富春江流域浮游植物群落结构影响至关重要,夏季高温季节流态变化可能是诱发富春江库区蓝藻水华的关键因子;降低藻类水华的风险,应在河流氮磷负荷控制的基础上,充分考虑水利调度的协同控制.

庞德时代的翻译标准是以忠实为核心的学术性翻译,要求译者忠实地传达原文的思想与精神。在自己的儒家经典翻译实践中,庞德反对以忠实为核心的学术性翻译,倡导译为创用、译为新作的译创融合思想,认为译文不是对原文的复制,而是一个不同于原作的新的作品。基于这种理念,庞德通过自身的儒家经典翻译实践对时代翻译标准发起了挑战。
