氧化还原介体催化强化污染物厌氧降解研究进展

 由于厌氧生物处理技术具有产生剩余污泥少、可回收能源等优点而被广泛用于处理各种有机污染物，尤其在有毒、有害、难降解污染物的去除方面取得了良好的效果。然而，厌氧生物法的处理速率通常比较低，而氧化还原介体可通过自身不断的氧化和还原来传递电子，提高电子在氧化还原反应过程中的传递速率，从而促进污染物高效厌氧降解。醌类物质和腐殖酸是应用较多的氧化还原介体，在催化难降解污染物降解方面取得了一定效果。讨论了氧化还原介体的特点、作用机制，并总结了其对偶氮染料厌氧脱色、反硝化和多氯联苯厌氧降解的强化作用，提出了氧化还原介体未来的研究方向。     

“百病生于气”疾病观的针灸临床应用

 “百病生于气”见于《素问·举痛论》，几千年来始终是中医临床认识疾病、防治疾病的重要理论依据之一。对气的含义及气机失调致病的机制进行了梳理，得出了“百病生于气”的基本含义可以概括为气机失调是疾病发生的基本病机的结论，情志因素、精神心理是导致疾病发生的重要内因。分析认为“百病生于气”的理论对于针灸临床有重要指导意义，针灸诊疗过程中应注重“调气”“调神”，这是针灸取得佳效的根本保障。

Multi-Interactions in Ionic Liquids for Natural Product Extraction

Natural products with a variety of pharmacological effects are important sources for commercial drugs, and it is very crucial to develop effective techniques to selectively extract and isolate bioactive natural components from the plants against the background of sustainable development. Ionic liquids (ILs) are a kind of designable material with unique physicochemical properties, including good thermal stability, negligible vapor pressure, good solvation ability, etc. ILs have already been used in pharmaceuticals for extraction, purification, drug delivery, etc. It has been reported that multi-interactions, like hydrogen bonding, hydrophobic interactions, play important roles in the extraction of bioactive components from the plants. In this review, recent progress in the understanding of scientific essence of hydrogen bonding, the special interaction, in ILs was summarized. The extraction of various natural products, one important area in pharmaceutical, by conventional and functional ILs as well as the specific roles of multi-interactions in this process were also reviewed. Moreover, problems existing in bioactive compound extraction by ILs and the future developing trends of this area are given, which might be helpful for scientists, especially beginners, in this field.     

砂岩在西湖凹陷花港组交互式盖层中的作用初探

西湖凹陷花港组盖层具有砂泥岩交互式发育特征，而与泥岩伴生的砂岩类盖层的油气封闭作用研究较少。采用岩芯、镜下观察及压汞等分析方法，对砂泥岩交互式盖层中的砂岩特征进行了分析。结果表明，盖层中的砂岩可作为有效盖层，砂岩类盖层早期受沉积环境控制，含有较多的泥质而导致早期压实作用较强，加之晚期的黏土矿物转换及胶结物的发育，具备形成良好盖层的条件。在不同地区进行砂岩盖层有效性研究时应以沉积环境为基础，针对不同类型的砂岩进行成岩作用研究，并针对不同类型的砂岩样品进行实验分析以明确砂岩盖层的有效性。

《近思录》的“教学之道”与朱熹的教育思想

朱熹的教育思想与《近思录》"教学之道"的语录文字联结紧密,二者存在相当的一致性;《近思录》语录文字是朱熹辑录与发明,是有意张扬四子思想,并藉以表达自己教育思想之取向。程朱理学,注重人之禀赋的开掘,达成圣贤;强调早期教育,"以豫为先",养成"圣贤坯璞";对传统教学内容的继承与拓展,尤重洒扫应对;对教法阐释透彻,继承而推新。这些在当下对我们有很好的启示。
