PE纤维与细橡胶颗粒对泡沫混凝土弯曲韧性的影响

第九届新型太阳能材料科学与技术学术研讨会

作者： guangcheng wu Xuting Dong Guanglei Cui School of Physics and Electronics Information Anhui Normal University

Owing to the outstanding photoelectronic properties, perovskite-based solar cells show prominent performance. Its stability hampers the progress of commercialization, so it is one of important topics to understand the microstructure mechanism of perovskite degradation under the humidity and oxygen environmental conditions. In this work,[1] a meaningful Debye-type dielectric relaxation was observed under water vapor and oxygen co-treatment condition. Interestingly, the relaxation was not observed under water vapor or oxygen treatment individually(Figure 1). This new dielectric relaxation is identified as a direct result of dipoles jump, and its activation energy measured as 630±6 meV. According to the photoelectron spectroscopy and C nuclear magnetic resonance, we suggest that the dipoles are formed by CHNH(MA) and superoxide(O), which originates from the distorted crystal and water vapor weakened hydrogen bonds of Pb-I cages. In addition, the activation energy fitted by dielectric relaxation might be the energy of ion migration. This work contributes to understanding the mechanism of perovskite degradation from the view of microstructure relaxation and evolution, and also provides a method to analysis ion migration energy.

研究了聚乙烯(PE)纤维及其与细橡胶颗粒复掺对泡沫混凝土弯曲破坏模式、峰值强度、能量吸收特性和弯曲韧性的影响,并结合孔结构分析和微观形貌观察探究了其作用机理.结果表明:PE纤维使泡沫混凝土出现多缝开裂模式,显著提升了其峰值强度、能量吸收能力和弯曲韧性;复掺细橡胶颗粒可以进一步提升泡沫混凝土试件的比能量吸收和弯曲韧性;掺入PE纤维可以降低泡沫混凝土的平均孔径;复掺细橡胶颗粒导致泡沫混凝土试件的平均孔径增大,联通孔增多,对其峰值强度有不利影响;PE纤维及细橡胶颗粒提升泡沫混凝土弯曲韧性的主要原因在于其削弱了裂纹尖端的应力集中,同时增强了能量耗散作用.

朋霍费尔(Dietrich Bonhoeffer,1906-1945)是一位杰出的德国神学家。他所倡导的狱中神学指出,世界已经成年,基督教乃是非宗教的、此世的信仰方式。耶稣的受苦和遭弃彰显了上帝的苦弱,做门徒的代价正是要追随基督的典范,积极地参与生活。这样的基督教观把上帝视为不在之在,对后世重新理解基督教提供了不同的思路,对战后的基督教神学理论建设乃至整个西方思潮产生深远影响。

论阿奎那创世论的形而上学原则

阿奎那的创世论有着鲜明的形而上学原则。在阿奎那看来,不仅信仰肯定创世,理性也同样证明之。阿奎那把存在视为本质的现实化,一种现实活动,把本质看成事物成其所是的依据,强调存在的现实性和本质的潜在性,以及存在对于本质的优先性。同... 详细信息

阿奎那的创世论有着鲜明的形而上学原则。在阿奎那看来,不仅信仰肯定创世,理性也同样证明之。阿奎那把存在视为本质的现实化,一种现实活动,把本质看成事物成其所是的依据,强调存在的现实性和本质的潜在性,以及存在对于本质的优先性。同时,他坚持存在即善的原则,从分有的角度看待万物的存在、善及其与上帝的存在的关联。立足于这样的一种形而上学原则,阿奎那的创世论显然就是一种存在论。上帝的存在与本质同一,就是一种纯粹的现实活动;创造作为上帝的神圣活动,就是存在的给予。而万物之受造,就是存在的分有。在不失信仰立场而又坚持理性原则的双重诉求下,阿奎那把创世论和形而上学有机结合,构建了一个谨严的理论范式。

约翰·希克是当代著名的宗教哲学家之一,宗教多元主义的积极倡导者。他通过对传统的宗教解释和自然主义的宗教解释的区分,试图做出一种综合性的宗教解释。他把宗教视为一种“家族相似”概念,并从人的认知规律和生活经验出发,对宗教的合理性做出某种辩护。他从神圣者因素和属人因素两方面来描述宗教,提出了他的“实在者”概念和救赎论结构,从而形成他的宗教多元时代里的宗教观。
