A highly diversified macrofossil assemblage was discovered from the Jiucheng Member of the uppermost Ediacaran of Jinning and Jiangchuan areas in eastern Yunnan. In addition to abundant Vendotaenia and Tyrasotaenia, large multicellular benthos such as Tawuia-like and Longfengshaniaceae fossils with diverse holdfast structures, have a distinct dominance, while there are still some other macrofossils with peculiar configurations as well as indistinct relatives. There is an obvious distinction between this assemblage and the macrofossil assemblages from the Doushantuo Formation and the Shibantan Member of the Dengying Formation in South China.

在中国云南东部晋宁、江川地区的埃迪卡拉系顶部灯影组旧城段，新发现了多样的宏体化石群，其中除了丰富的Vendotaenia与Tyrasotaenia类化石以外，以形体较大的Tawuia类和Longfengshaniaceae科等具固着构造的底栖多细胞藻类化石占据优势，另有一些形态奇特、亲缘关系不明的宏体化石，该组合与华南陡山沱组和灯影组石板滩段的宏体化石组合存在着明显的差别。

The second chapter describes the formation of the pool of state controlled lands and the establishment of land market. The third chapter analyzes the government policies regarding land sale from the Independence to 1850s and the federal government"s diversified land distribution polices in the latter half of the 19th century. In the Forth chapter, the author assesses how American government" s land policies assisted the development of agriculture, communications and transportation, western urbanization and the formation of a national market. Chapter Fivediscusses the controversial issues of the land speculation and The Homestead Law, which affected the governments land policies.

全文分五章：第一章简要介绍美国土地问题的研究概况；第二章描述了美国建国以后国有土地的形成和国有土地市场的建立；第三章分析了美国建国后至十九世纪中期联邦政府以销售为主的土地政策，以及十九世纪后半期联邦政府多元化的土地分配政策；第四章从农业、交通运输业、西部城市化、国内统一市场四个方面入手，分析了土地政策对西部开发的推动作用；第五章对与土地政策密切相关的、学术界争论较大的土地投机问题和《宅地法》进行了简评。

The heavy mudstone layers in Third Member of Shahejie Formation (Es3) provide favorable hydrocarbon source rock and cap formation, diabase and hornfels belts serve as reservoirs, faults and microcracks in the wall rocks as the pathways for oil and gas migration.

沙三段厚层生油岩为火成岩储层提供了良好的烃源岩和封盖层；辉绿岩及角岩带为主要的储层带；断层及围岩中的微裂缝为油气运移提供运移通道。

By using the theories of conservation of momentum,conservation of energy and hydrokinetics,a mathematical model for describing the relationship among the fluid parameters,the formation parameters and the vibrant operation parameters was established.The analytic solutions of one-dimensional and radial transfusion equation for compressive and single-phase fluid flow through the compressive formation were obtained.The effects of each parameter on the vibrant operation were also gotten.On the basis of the above results,the computation models were established.

应用动量守恒、能量守恒、流体动力学等基本原理，建立了地层参数、流体参数和振动作业参数之间相互耦合的数学模型，求出了单相微可压缩流体在可压缩地层中的平面一维和平面径向渗流方程的解析解，得到了各项参数与振动作业效果之间的关系，为振动采油的数值模拟提供了初始压力分布表达式。

On research of the study of low permeability formation and damage characteristic of Xing shu gang oilfield, we acquire why the injection wells have problems of little hygroscope thickness and low hygroscope capacity.

本文针对杏树岗油田薄差层渗透率低、物性差、粘土含量高、吸水能力较差的问题，通过对杏树岗油田薄差层储层敏感性评价和储层伤害机理的研究，详细分析了造成该油田注水井吸水能力较差的原因。

Thisarticle attempts to study the formation, characteristics and humanistic implications ofChinese hymnody in three chapters. Chapter 1 introduces the formation anddevelopment of Chinese hymnody from the political, religious, and culturalperspectives. Chapter 2 analyzes the various features of Chinese hymnody anddemonstrates that Chinese hymnody is a synthesis of Chinese and western culture andmusic. Chapter 3 explains the value, significance and influence of Chinese hymnodytoday from cultural, progressive, and aesthetic perspectives.

第一章简介了中国基督教圣诗音乐生成的政治及宗教文化背景，指出其对中国基督教圣诗音乐的作用与影响，并梳理了中国基督教圣诗音乐本色化发展概况；第二章论述了中国基督教圣诗音乐的多样性及崇拜性表现特征，从词曲的来源、和声的民族化及在崇拜中的表现特征分析中国基督教圣诗音乐中西融汇的多元特征；第三章是从人文角度对中国基督教圣诗音乐的透视，从其文化内涵、现代性变迁及审美取向来三个方面阐明了中国基督教圣诗音乐在当代的价值、意义及影响。

Furthermore, the NBO calculation implies that relative stabilities of all 15 conformers can be attributed to the steric and hyperconjugation effects. In addition, the result derived from G3MP2 shows that the heats of formation of all conformers are positive and heats of formation of ring conformers are greater than those of chain conformers.

而且，NBO的立体和超共轭分析表明立体交换排斥能和超共轭作用对这些分子的相对稳定性起了重要作用。G3MP2计算结果表明氮氢化合物的生成热均为正，并且环状分子的能量和生成热都高于链状分子。
