Copper(0)-mediated reversible-deactivation radical polymerization(Cu(0)-mediated RDRP) of the water-soluble monomer Nisopropylacrylamide(NIPAM) has been challenging with the problems of high dispersity, poor control over the molecular weights(MWs) or complex or multi reaction steps, etc. In this work, we report the well-controlled polymerization of NIPAM in water via a facile one-pot and one-step Cu(0)-mediated RDRP. The results of this approach show that the key for kicking off the Cu(0)-mediated NIPAM RDRPs is to ensure sufficient Cu~I at the very beginning, and the key to achieve a well-controlled chain growth is to provide adequate deactivation strength during the polymerization process. For NIPAM, which has a high propagation rate constant, the deactivation control can be effectively enhanced by extra adding deactivator(i.e., Cu~II) to the system. Moreover, a low reaction temperature(4 ℃) is necessary in the controlled synthesis of higher MW poly(Nisopropylacrylamide)(PNIPAM) to avoid the compromise in control caused by the phase transition from its lower critical solution temperature(LCST). Through this new kinetically controlled strategy, PNIPAMs with well-defined structure, narrow molecular weight distributions(MWDs) and varied MWs were successfully achieved.

跨界是一种特殊的叙事现象,是指文学作品中的人物、情节、场景等从一个叙事空间迁移到另一个叙事空间。借助可能世界理论中的“跨界同一性”(transworld identity)和“客观对应物”(counterpart)这两个核心概念,可以把跨界叙事划分为纵向跨界叙事和横向跨界叙事两大类型,其中纵向跨界又可以分为下降跨界叙事和上升跨界叙事,而横向跨界叙事则可以细分为同文本横向跨界叙事和跨文本横向跨界叙事。利用可能世界理论的方法对跨界叙事问题进行系统的分类研究,可以从新的视角审视元小说、平行世界、衍生、戏仿、挪用等后现代文学现象,探讨跨界叙事产生的效果。

作为一种跨学科的方法,认知叙述学融合了认知科学和叙述理论,致力于探讨叙事与思维或心理之间的关系,试图解释文学作品中的叙述元素是如何理解、处理和影响人类认知的。然而,由于认知固有的个体化、主观性和不确定性特征,认知叙述学无法成为一种具有普适性的理论。通过对认知叙述学的几个基本概念——“故事世界”“脚本”“体验性”“感受质”批判性地审视,不难发现认知叙述学依然面临一些不发达领域,并存在一些潜在的问题。因此,认知叙述学的理论假设、论证过程和研究发现是否具有有效性和科学性,是需要进一步考察和验证的。

结合秸秆生态补偿特色,构建多元主体协同下的生态补偿框架,阐述框架的运行逻辑,并以山东省郯城县为例,从运行主体、运行制度及运行成效3个方面对生态补偿框架的具体运行进行分析。研究认为:多元主体协同下的生态补偿需要政府、市场与社会公众的共同参与,其中产权界定是市场参与的关键,制度安排、法律监督为政府与市场协同提供保障,政府间职能差异为府际协同创造条件,社会公众参与形成第三方合力。多元主体协同下秸秆生态补偿机制是推进秸秆综合利用和生态修复的重要手段。最后,提出未来需要在生态补偿主体产权界定、多元主体协同下秸秆生态补偿制度和法律体系构建、社会公众参与、府际协同等方面进行完善和优化。

As critical components of aircraft skins and rocket fuel storage tank shells,large thin-walled workpieces are susceptible to vibration and deformation during machining due to their weak local stiffness. To address these challenges, we propose a novel tunable electromagnetic semi-active dynamic vibration absorber(ESADVA), which integrates with a magnetic suction follower to form a followed ESADVA(follow-ESADVA)for mirror milling. This system combines a tunable magnet oscillator with a follower,enabling real-time vibration absorption and condition feedback throughout the milling process. Additionally, the device supports self-sensing and frequency adjustment by providing feedback to a linear actuator, which alters the distance between magnets. This resolves the traditional issue of being unable to directly monitor vibration at the machining point due to space constraints and tool interference. The frequency shift characteristics and vibration absorption performance are comprehensively investigated. Theoretical and experimental results demonstrate that the prototyped follow-ESADVA achieves frequency synchronization with the milling tool, resulting in a vibration suppression rate of approximately 47.57%. Moreover, the roughness of the machined surface decreases by18.95%, significantly enhancing the surface quality. The results of this work pave the way for higher-quality machined surfaces and a more stable mirror milling process.
