Five typical coals of low-to-medium rank (Huolinhe brown coal, Majiata non-caking coal, Datong weakly caking coal, Huozhou gas coal, Lingshi fat coal) and their macerals are prepared. The molecular structure and the oxygen functional groups of the selected coals and their macerals are studied by means of the conventional coal properties analysis, chemical analysis and the advanced instrumental methods such as FTIR,XRIK 13C-NMR.N XPS. The molecular structure characteristics, regularities and the results are discussed. Additionally, the total oxygen content and distribution characteristics of different oxygen functional groups in the raw coals and their macerals are studied.
本文中选取了中低变质程度煤中的五种典型煤种——霍林河褐煤、马家塔不粘煤、大同弱粘煤、霍州气煤、灵石肥煤以及它们的不同显微组分作为研究对象,采用了常规的煤质分析、化学分析法以及先进的仪器分析法如傅立叶变换红外光谱、X射线衍射、高分辨固体~(13)C核磁共振谱~(13C-NMR及X光电子能谱等方法,全面地研究分析了所选煤样的惰质组、镜质组的分子结构及煤中氧的赋存形态,得到所选煤样惰质组分的分子结构特征及结构参数,分析比较了惰质组与镜质组在分子结构上的差异性,并讨论了惰质组分的分子结构特征及结构参数随煤变质程度的变化规律;同时,通过研究得到了所选原煤样及其显微组分中总氧含量及各种不同类型含氧官能团的含量分布特征。

我们测定了斑腿蝗科10亚科20种蝗虫和其它蝗科3种蝗虫的16S rDNA序列片段,并从GenBank中下载了斑腿蝗科3种、其它蝗科10种及蚱总科2种的16S rDNA相应序列片段,然后对这共计38种蝗亚目昆虫的16S rDNA序列片段进行了同源性比较,以其中2种蚱作外群构建了蝗总科的分子系统树,得到的结论如下:1斑腿蝗科并非是一单系群。2该科中的切翅蝗亚科、稻蝗亚科、黑蝗亚科、秃蝗亚科、卵翅蝗亚科、蔗蝗亚科均不是单系群,分子系统树的聚类结果与基于形态特征的斑腿蝗科的分类体系有较大的出入。3支持将黑蝗亚科和秃蝗亚科合并为一个亚科——秃蝗亚科。4卵翅蝗、伪稻蝗和稻蝗三者有很近的亲缘关系。

Except the foreword, this paper is divided into four chpaters:Chapter One: the common vivid featrues of dramatic personae in the phyletic biography of people in Shiji. The charater accords with the described methods, it has the obvious feature of kindred, It leans to the type of the figural creation in our country's later gerneration novels.Chapter Tw phyletic biography of people not extrudes the common featrue of drmatic personae but also emphersizes the personality description. The figural creation turns personal description from typical description gradually in the later generation novels, although the same typical charaters have the differnt lookings.Chapter Three: phyletic biography of people stands out the charaters with the typical events, the same charater can appears the differnt phyletic biography of people, it shows the differnt features (This is the commuteritive incarnate in Shiji). The later generation novels figure the charaters with their action, the same character lean to the differnt points, they show their differnt characteristics.Chapter Four: phyletic biography of people has the multiform modality, it includes paratactic description, coherend interclude, cascade rising and so on. The later generation novels use for reference the paratactic in the arrange of polt structure.
除引言外,全文分为四部分:第一章:《史记》各&类传&中&传主&的共同特征鲜明,人物选择符合以类相从、连类相及的方法,&类&的特色极为明显;我国后世小说中人物形象塑造呈现出类型化的倾向;第二章:&类传&在突出传主共同特征的基础上也注重人物的个性描写,传中人物在符合&类属&的前提下自身的特色同时显现出来:后世小说中人物形象塑造逐步由类型化向个性化发展,即便是同一群体的人物也具有各自不同的面目;第三章:&类传&选取传中人物的典型事件来突出人物形象;同一人物可以进入不同的类传中,表现出不同的特性(这是《史记》全书人物塑造上的&互现法&的典型体现);后世小说中注重选择具有行动性特征的细节来塑造人物形象;同一人物在不同作品中有不同的侧重,呈现出不同的面目;第四章:&类传&结构安排的多样形式,主要有并列分叙、联贯穿插、层叠上升等几种形式;后世小说在情节结构安排上对&类传&的借鉴。
