理智 禁锢——解读《到十九号房间》的悲剧结局

小说《到十九号房间》讲述了一位现代知识女性自杀于一家小旅馆的十九号房间的悲剧故事。女主人公在迷失自我与寻找自我的矛盾中挣扎,最终以自杀的方式寻求彻底的解脱。她悲剧人生的内在原因是理智束缚下的女性内心世界的痛苦矛盾,造成女主人公人生悲剧的更深层次的社会根源是男性中心主义价值观。

《一千英亩》的女性主义解读

简·斯迈利的《一千英亩》的故事框架来自于莎士比亚的《李尔王》，但表现的却是不一样的主题和意义。小说通过女主人公吉妮与三位男性的情感纠葛，揭示出了父权制对女性的压抑和紧闭，同时通过对吉妮女性自我意识觉醒和反叛的描写，表达了新一代美国女性要求摆脱传统束缚、获得独立和自由的心声。     

Dynamic confinement of SAPO-17 cages on the selectivity control of syngas conversion

The OXZEO (oxide−zeolite) bifunctional catalyst concept has enabled selective syngas conversion to a series of value-added chemicals and fuels such as light olefins, aromatics and gasoline. Herein we report for the first time a dynamic confinement of SAPO-17 cages on the selectivity control of syngas conversion observed during an induction period. Structured illumination microscopy, intelligent gravimetric analysis, UV-Raman, X-ray diffraction, thermogravimetry and gas chromatography-mass spectrometer analysis indicate that this is attributed to the evolution of carbonaceous species as the reaction proceeds, which gradually reduces the effective space inside the cage. Consequently, the diffusion of molecules is hindered and the hindering is much more prominent for larger molecules such as C₄₊. As a result, the selectivity of ethylene is enhanced whereas that of C₄₊ is suppressed. Beyond the induction period, the product selectivity levels off. For instance, ethylene selectivity levels off at 44% and propylene selectivity at 31%, as well as CO conversion at 27%. The findings here bring a new fundamental understanding that will guide further development of selective catalysts for olefin synthesis based on the OXZEO concept.

Analysis and behaviour of FRP-confined short concrete columns subjected to eccentric loading

Fibre-reinforced polymer （FRP） composites were widely utilized in civil engineering structures as the retrofit of reinforced concrete （RC） columns. To design FRP jackets safely and economically, the behaviour of such columns should be predicted first. This paper is concerned with the analysis and behaviour of FRP-confined RC circular and rectangular short columns subjected to eccentric loading. A simple design-oriented stress-strain model for FRP-confined concrete in a section analysis was first proposed. The accuracy was then proved by two test data. Following that, a parametric study including amount of FRP confinement, FRP strain capacity, unconfined concrete strength and shape of column section is provided. Some conclusions were obtained at the end of the paper. The work here will provide a comprehensive understanding of the behaviour of FRP-confined concrete columns. The simplicity of the model also enables a simple equivalent stress block to be developed for direct use in practical design.
