Chapter 3 the Persian war, chapter 4 the Vandal war, chapter 5 the Gothic war are all about the same issue "Wars and Peace."By analyzing every war's cause, process, I then make a conclusion of Procopius'conception of history. Chapter 6 "Natural Calamity and Human Disaster"analyzes and discusses the Plague of Constantinople in 542-543 and "Nika riot"in 532. In chapter 7 "Legend, Customs and Natural Phenomena", besides a scrutiny of Procopius'history criticism, I examine and sum up three kinds of digressions in this work. The last chapter "Military and Religion"inquires into the military organization , armies of the services, equipments, strategy and tactics, weapons of Byzantine empire. This chapter also probes into the attitude of Procopius on Christian, heresies and paganism; The epilogue is a conclusion of this dissertation, making a systematic exposition on Procopius'conception of history.

对这三大战争的研究，笔者采用述论相结合的方法，首先分析各大战争爆发的原因，然后详细分析战争的过程，纠正普罗柯比的正误、讳言之处，通过与其他史料的相互对比还原历史真相，总结经验教训，最后，在每章的总结部分论述战争的结果及其对交战双方的影响，通过对具体内容的分析归纳总结普罗柯比的历史观；第六章&天灾与人祸&主要对《战记》中记载的542-543 年君士坦丁堡大瘟疫和532 年尼卡暴乱加以分析论述，通过普罗柯比与其他史家记载的对比探寻查士丁尼大瘟疫的起源、传播路径、症状、传染介质、死亡人数、政府对策及其影响等问题，通过对尼卡暴乱目击者记录的分析揭示尼卡暴乱爆发的原因、真实过程，对尼卡暴乱作出公允的评价；在第七章&神话传说、民族风俗和自然现象&中，通过普罗柯比对这三类插话描写的总结和评论，分析他的历史批判法；在最后一章&军事与宗教&中，剥开《战记》的表层内容，对其中蕴含的较深层次的思想内容进行研究，如拜占廷帝国的军队组织、兵种、装备、战略战术、军事武器等内容的探讨，同时也就普罗柯比对基督教和异教、异端的态度加以分析论述；最后的结语部分主要是作全文的总结，阐述普罗柯比的历史观。

She was lost in 1921 apparently when a structural failure jammed her controls and sent her crashing into power lines near her base near Hampton Roads Va. Filled with hydrogen; she exploded in flames, killing thirty-four crew. The disaster was a major reason for the movement from hydrogen to helium in American airships..

一旦蒙皮里充满压力气体（H2）的时候，升降气囊就会使他像软式飞艇那样浮起来。1921年，他在弗吉尼亚州的汉普顿路附近坠毁，原因很清楚，一处结构损坏，卡住了他的控制器，使他一头撞上了基地附近的电线，造成泄露的氢气爆炸，致使34名机组人员死亡，这场灾难是导致美国飞艇转用氦气的主要原因。

In order to disclosure the reason why the electrocatalysis activeness and selectivity droped after being used several hundred hours continuously, the x-ray diffraction, scanning electron microscopy and energy dispersive spectroscope have been used to characterize the surface condition variations of Monel metal. The results indicated: Monel metal belongs to the Cu-Ni alloy around the electrolysis experiment.And after being used for 600hr, the surface layer element composition and geometry distribution of the alloy changed, namely in the alloy the Cu element /which superficial free enthalpy was smaller,"concentrated" to the alloy surface,and formed one kind of marble structure microcrystallite.Thus the electrode surface becamed rough a

为了揭示蒙乃尔合金阴极在连续使用数百个小时后电催化活性剂选择性下降的原因，采用X射线衍射仪、电子扫描电镜和电子能谱分析仪对电解实验所用的蒙乃尔阴极材料在电解实验前后的表面状态进行了表征，结果表明：所使用的蒙乃尔合金阴极材料在电解实验前后均属于Cu-Ni合金，使用600hr后，由于表面层元素组成和几何排布发生了变化，即合金中表面自由焓较小的Cu元素向合金表面&富集&，形成一种大理石结构的微晶，表面粗糙、不均一，这是造成其对硝基苯电还原的催化活性及选择性随着使用时间延长而逐渐下降的主要原因，同时也为此类电极的修饰改进提供了方向。
