  • 1949年後周作人散文中,有關魯迅的回憶文章是其重要組成部分。特别是《魯迅的故家》,展现了形成當下周作人鲁迅的过去经验,根源,历史,文化,地域传统以及逐渐衰败的士大夫家的荒凉内面。周作人在《魯迅的故家》上的魯迅回忆法很独特。明明以魯迅的文章《朝花夕拾》为引子,但很快就超越了原本。他望着被魯迅漏掉或遗忘的百草园内外徘徊。那里有鬼園,有漂泊在鬼園之上的灵魂,也有些生活在想象和历史的境界里的人。甚至还有被他遗忘似的祖父和父親。《魯迅的故家》在虚构和历史,想象和事实或魯迅和周作人这两个领域之間无数次往返,跳跃,并创造出上下四面扩张的新世界。但是在这个时空中,真实和虚构已经不再是個问题。因为在虚构和事实之间徘徊的《魯迅的故家》中的人和事不知不觉间变得更加立体,时时刻刻变化,拥有丰富的内涵。 但是另一方面,随着《魯迅的故家》中出现的魯迅周围人物和事迹具有具体的质感,魯迅本身其形象和存在感也变得模糊不清。因此,"《魯迅的故家》实际上是周作人的故家"的不满和由周作人對魯迅谈论的结果,被认为是 '对左翼鲁迅的放逐'。周作人復原了魯迅早年和青年時代。那是被推頌爲 "現代中國聖人","革命家"以前的周作人長兄的魯迅,是生活在衆多背景和事件中凡人魯迅,是非革命性的非戰鬥性的魯迅。這是周作人創造的另 一個世界,是周作人和魯迅的文學和學術發祥地,也接近于曾分化成許多不同面貌的原生質世界。

  • This study investigated the effects of nanoparticles on the fracture toughness of cement mortar. Three-point bending tests, compressive tests, and slump tests were conducted on cement mortars reinforced with carbon nanotubes(CNTs), nanosilica(NS), and nano calcium carbonate(NC), respectively. Cement mortar with a water-to-cement ratio and a sand-to-cement ratio of 0.45 and 1.5, respectively, and reinforced with 0 and 2 vol.% of 19.5 mm steel fibers, respectively, was used. Reinforcement with nanoparticles partially improved the fracture toughness and compressive strength of the cement mortar. However, in the case of cement mortar reinforced with steel fibers, the reinforcement with nanoparticles was found to reduce the flowability of the mortar, adversely affecting the dispersion of steel fibers, and ultimately leading to a decrease in fracture toughness, contrary to the intended enhancement. Additional research is needed to improve the decrease in mortar fluidity caused by the reinforcement with nanoparticles.
