A modified piano key weir with a rounded nose and a parapet wall (MPKW) can improve the discharge capacity significantly compared to a standard piano key weir. However, the optimum of the inlet/outlet width ratio (Wi/Wo) on the discharge efficiency of MPKW is still not investigated numerically. The present work utilized the numerical modeling to investigate and analyze the effects of the inlet/outlet key width ratios on the hydraulic characteristics and discharge capacity of the MPKW. To validate the numerical model with the experimental data, the results indicate that the average relative error is 2.96%, which confirms that the numerical model is fairly well to predictthe specifications of flow over on the MPKW. Numerical simulation results indicated that the discharge capacity of the MPKW can be improved up to 8.5% by optimizing the Wi/Wo ratio ranging from 1.53 to 1.67 even if the other parameters of the MPKW keep unchanged. A big Wi/Wo ratio generally leads to an increase in discharge capacity at low heads and a little effect on the discharge efficiency at high heads. The discharge efficiency of the inlet and outlet crests increases up to 9.6% for high heads, while discharge efficiency of the lateral crest decreases up to 23.5% compared with the reference model. The findings of the study revealed that the intrinsic influencing mechanism of the Wi/Wo ratio on the discharge performance of MPKWs.

本文认为文艺复兴时期人文主义文学在汲取“两希”文学的人文养料后,孕育出了西方文学现代形态里“人”的母题。这一母题的文化包容性反映出作为文艺复兴指导思想的人文主义之内涵的丰富性和文化互补性。人文主义对现代西方社会的意义,不仅仅表现在它对人智与原欲的解放上,还表现在它对人的精神与理性的提升上。以世俗人本传统为核心内容的现代价值观推动着西方社会的发展,但也有明显的弊端。

《魂断威尼斯》(Morte a Venezia,1971)改编自德国作家、1929年诺贝尔文学奖得主托马斯?曼(Thomas Mann)的小说《死于威尼斯》(Der Tod in Venedig,1911),讲述了年过半百的作曲家古斯塔夫?阿申巴赫(Aschenbach)来到威尼斯城休养,却痴狂地迷恋上美少年塔奇奥(Tadzio),而无暇顾及此时横行的霍乱,最终染疾而亡的故事。“互文性”(Intertextuality)是由后结构主义符号学家朱丽娅?克里斯蒂娃(Kristeva)结合巴赫金的对话理论而提出来的概念,她认为所有的文本都是由其他文本编织、拼贴而成,是一种“马赛克的建构”。[1]简而言之,“互文性”就是指在文本主体性以外的相互关系。而对于电影与文学尤其是“经典改编”来说,二者之间的关系便是“跨媒介互文性”。一部电影在被制作和被阐释的过程中,既可能包含对文学等其他艺术形式的映射,也可能包括对过往电影的指涉,还有可能包括对性别、地域、宗教等诸多文化要素的投射。

The high content of aluminum(Al)impurity in the recycled cathode powder seriously affects the extraction efficiency of Nickel,Cobalt,Manganese,and lithium resources and the actual commercial value of recycled materials,so Al removal is crucially important to conform to the industrial standard of spent li-ion battery cathode *** this work,we systematically investigated the leaching process and optimum conditions associated with Al removal from the cathode powder materials collected in a wet cathode-powder peeling and recycling production line of spent li-ion batteries(liBs).Moreover,we specifically studied the leaching of fluorine(F)synergistically happened along with the removal process of Al,which was not concerned about in other studies,but one of the key factors affecting pollution prevention in the recovery *** mechanism of the whole process including the leaching of Al and F from the cathode powder was indicated by using NMR,FTIR,and XPS,and a defluoridation process was preliminarily investigated in this *** leaching kinetics of Al could be successfully described by the shrinking core model,controlled by the diffusion process and the activation energy was 11.14 kJ/***,the leaching of F was attributed to the dissolution of liPF6and decomposition of PVDF,and the kinetics associated was described by Avrami *** interaction of Al and F is advantageous to realize the defluoridation to some *** is expected that our investigation will provide theoretical support for the large-scale recycling of spent liBs.

超验主义是美国历史上承前启后的哲学思潮。超验主义的出现,既是艾默生等人对17世纪以来美国清教主义传统的反思,也是对美国19世纪飞速发展的工业文明的忧虑和反省。超验主义的自然观,既是对古希腊人与自然相分离的传统的反拨,同时也带有一定的中国道家“天人合一”的特点。艾默生等人通过回归自然的方式表达了对人的自由、尊严与灵魂价值的肯定,一定程度上体现了19世纪处于上升时期的美国人对人与社会、人与自然关系的浪漫主义思考。

Anode-free solid-state lithium metal batteries(AF-SSLBs)have the potential to deliver higher energy density and improved safety beyond lithium-metal ***,the unclear mechanism for the fast capacity decay in AF-SSLBs,either determined by dead li or solid electrolyte interface(SEI),limits the proposal of effective strategies to prolong cycling *** clarify the underlying mechanism,herein,the evolution of SEI and dead li is quantitatively analyzed by a solid-state nuclear magnetic resonance(ss-NMR)technology in a typical liPF6-based polymer *** results show that the initial capacity loss is attributed to the formation of SEI,while the dead li dominates the following capacity loss and the growth rate is 0.141 mA h cm^(−2)cycle−*** reduce the active li loss,the combination of inorganic-rich SEI and self-healing electrostatic shield effect is proposed to improve the reversibility of li deposition/dissolution behavior,which reduces the capacity loss rate for the initial SEI and following dead li generation by 2.3 and 20.1 folds,*** a result,the initial Coulombic efficiency(ICE)and stable CE increase by 15.1%and 15.3%in li-Cu cells,which guides the rational design of high-performance AF-SSLBs.
