目的研究除草剂丁草胺对泥鳅(Misgurnus anguillicaudatus)体内重要器官过氧化物酶(POX)、非特异性酯酶(NSE)、碱性磷酸酶(ALP)、酸性磷酸酶(ACP)、琥珀酸脱氢酶(SDH)和腺苷三磷酸酶(ATPase)等6种代谢与免疫相关酶活力的影响。方法将泥鳅暴露在不同浓度的丁草胺中96 h,解剖取其心脏、肝胰脏、鳃、头肾、胃和肠等6种器官,采用冰冻切片、酶组织化学及光密度分析技术检测酶活力变化。结果POX在头肾中活性显著较高,其余器官中活性均较低;高浓度丁草胺显著抑制头肾POX活性,但显著促进肝胰脏、胃和肠POX活性。NSE在肝胰脏中活性显著较高,心脏中活性显著较低;高浓度丁草胺对除心脏和胃以外的体内器官NSE活性具有显著抑制作用。ALP在胃中活性显著较高,心脏和头肾中未检测出明显的酶活性;高浓度丁草胺显著抑制胃和肠ALP活性,对肝胰脏和鳃ALP活性无显著影响。ACP在胃和肠中活性显著较高,心脏中活性显著较低;高浓度丁草胺显著抑制肝胰脏、鳃、头肾、胃和肠ACP活性,对心脏ACP活性无显著影响。SDH在心脏中活性显著较高,鳃和头肾中未检测出明显的酶活性;高浓度丁草胺显著抑制心脏、肝胰脏和胃SDH活性,对肠SDH活性无显著影响。ATPase在心脏中活性显著较高,头肾和肠中活性显著较低;高浓度丁草胺显著抑制心脏、肝胰脏和头肾ATPase活性,但对胃和肠ATPase活性具有显著促进作用。结论丁草胺可能通过抑制心脏SDH和ATPase活性影响泥鳅的血液循环,通过抑制胃和肠ALP和ACP活性降低泥鳅对营养物质的消化和吸收能力,通过抑制肝胰和头肾NSE、ACP和ATPase活性损害泥鳅的解毒与免疫防御功能。

There are many kinds of linear canonical transform(LCT)-based Wigner distributions(WDs),which are very effective in detecting noisy linear frequency-modulated(LFM) signals. Among WDs in LCT domains, the instantaneous cross-correlation function type of Wigner distribution(ICFWD) attracts much attention from scholars, because it achieves not only low computational complexity but also good detection ***, the existing LCT free parameters selection strategy, namely a solution of the expectation-based output signal-to-noise ratio(SNR) optimization model, is not unique. In this paper, by introducing the variance-based output SNR optimization model, a multiobjective optimization model is established. Then the existence and uniqueness of the optimal parameters of ICFWD are investigated. The solution of the multiobjective optimization model with respect to one-component LFM signal added with zero-mean stationary circular Gaussian noise is derived. A comparison of the unique parameters selection strategy and the previous one is carried out. The theoretical results are also verified by numerical simulations.

克莱斯特在《洪堡亲王》中一反普鲁士以情感控制为核心的斯多葛主义传统,再现了洪堡亲王的抗命激情与死亡恐惧。本文拟通过探讨这一情感表现与18世纪电学知识之间的关联,为克莱斯特“对普鲁士趣味谜样的违背”提供一种解读视角。克莱斯特在18世纪电学知识的基础上展开文学想象,借助静电感应的极化原则塑造了洪堡亲王在勇敢和怯懦的情感两极之间的往复与突变,因此主人公的死亡恐惧作为其中一极必然会被涉及。18世纪电学的蓬勃发展导致电成为爱情和灵感的情感隐喻,克莱斯特在剧中频频用雷电隐喻洪堡亲王违抗作战计划的冲锋激情的动机与内涵,是对上述现象的挪用与重构,其深意最终指向了以电为“绝对隐喻”的现代战争。

德国作家米夏埃尔・勒斯的《黑分五色》是现当代德国文学史上第一部以南京为叙事背景的长篇小说。本文结合德・赛托和本雅明的城市空间理论,关注小说主人公在南京城中的“行走”与“游荡”这两种空间实践的意义内涵:前者表现了霍尔茨寻觅异质空间的日常生活美学实践,后者则蕴涵了他对现代都市及现代性本身的矛盾性体验。主人公的双重空间实践构建出南京作为文学空间的三重维度,即中国传统水墨画美学渲染下的诗意自然空间、文化他者视角下的汉字符号空间和具有“魅像”色彩的都市梦幻空间,呈现出古典与现代杂糅的迷人城市意象。
