摘要:1988年,Okamura和Ishiwata在脊椎动物骨骼肌肌原纤维发现了张力和肌节长度的自发振动,并称之为SPOC(spontaneous oscillation contraction)。SPOC发生的条件是让肌肉处于松弛-收缩的中间态。这一条件可通过高浓度的MgADP和Pi或者低于微摩尔浓度Ca2+实现。
  关于肌肉的自发振动国外学者建立了两个理论模型,这些理论拓展了我们对肌肉收缩及其自发振动的认识,但理论结果很难与实验结果进行比较。内蒙古大学生物物理学科工作者利用Baker等人给出的肌肉态方程,建立了等张力条件下肌肉收缩及其自发振动的理论模型,并且理论结果与实验结果基本相符,但无法解释等长条件下的肌肉收缩及其自发振动。针对这一问题,本文利用肌肉收缩时的张力及各种弹性成分,结合肌肉的特殊结构,建立等长条件下肌肉收缩及自发振动的动力学方程,理论结果同实验结果基本相符。
  本文共分为四章,第一章介绍了肌肉收缩的滑行学说、肌球蛋白的结构、肌球蛋白工作循环的机械化学偶联。第二章介绍了肌肉收缩及其自发振动的定义及其特性。第三章介绍了国内外学者对SPOC的历史研究。第四章是本文的核心内容,基于对肌肉收缩及其自发振动的理解,构建了等长条件下肌收缩的动力学模型,并且将得到的理论结果与实验进行相比较。

摘要:Possession is a work written by A.S.Byatt in her brilliant period of writing andgot published in 1990.It talks about two modern scholars chasing after themysterious past of two fictive Victorian poets.Its modem and Victorian historicalbackground and writing techniques draw attention from scholars from both home andabroad.The author of this paper conducts her researches on Byatt's historiographicwriting strategies by utilizing theories of Linda Hutcheon and narratological theories.First of all, this paper reviewed some existing researches on Possession done byChinese and foreign scholars.Thus, from the literature review, the author of this paperdeduced to focus on the historiographic writing strategies of Possession as aneo-Victorian novel which is rarely dabbled.
  First of all, this paper introduces some basic information about neo-Victoriannovel.Three aspects are included in this part as historical background of the rising ofneo-Victorian novel, its development and its features.Then it comes to the specificstrategies applied by Byatt in Possession in her historiographic writing process.Inchapter three, the paper focuses on the spatiotemporal strategy of this novel.Byemploying spatial theory of Joseph Frank and temporal theory of narratology, twoperspectives are illustrated.First, history is traced through presenting fictive historicalmaterials to build the temporal order.Then the author analyzed its spatial order thatcontains history through Victorian locale descriptions.In chapter four, intertext isinvolved to uncover the historiographic writing strategies of Byatt.Because Byattuses fairy tales, myths and Victorian poems and historical figures in this novel, thefunctions of intertexts in contributing to historiographic writing should be analyzed.This paper picks out important intertexts such as The Glass Coffin, Melusina,Proserpina, images in Victorian poems to study on.In this way, her peculiar method oflinking history to literature is discovered.The other strategy contributed tohistoriographic writing in this novel is the suppression strategy.Chapter five tries toanalyze the function of the order of presenting history by switching points of view andstory layers of the novel.
  At the end, the author of this paper conclude that Byatt successfully modesPossession into a typical postmodern novel by applying techniques like special formto present time and space, intertexts and shifting of points of view and story layers.Asa neo-Victorian novel, its historical background is foregrounded to enlighten themodern people and readers by linking history, reality and literature together.
