With respect to syntax, the roles of tagmeme in the structure of word and sentence and Chomsky's Generative-Transformational Grammar are discussed. The spatial relation theory and existing research achievements are investigated. Having noticed the shortage of the capability of topological and metrical relation in the description of spatial information structure, the author proposes Combinational Qualitative Geometry based on the two invariables under ordinary transformations, distance ratio and direction difference, the CQG-based spatial relation system between topological and metrical constraint is thus constructed, on which several spatial relations such as parallel, perpendicularity, co-linearity, sequence and direct neighborhood are derived. Based on extended theory of spatial relation, the language anamorphosis is analyzed from the aspects of phonetics, semantics and syntax. The mere geometric and formalized spatial relation is then integrated with concrete geographic ontology to accommodate richer and indicative spatial configuration of spatial information in the different geographic context. Finally a syntax framework for spatial information is put forward.
在语法结构方面,首先阐述了法位和法素在语法结构词法和句法中的地位和作用,以及Chomsky生成转换语法的核心内容;详细介绍了地理信息系统空间关系理论及现有的研究成果;在分析现有的拓扑关系和量度关系对空间信息结构描述能力不足的基础上,提出了基于长度比和角度差两个不变量的组合定性几何,以此建立了介于拓扑及量度约束之间的组合定性关系体系,并以此为基础派生出平行、垂直、共线、次序、直接邻近等空间关系描述;本文基于扩展的空间关系理论,详细讨论了空间关系在语音、语法和语义三个方面的语言变体,将纯几何和纯形式化的空间关系与具体的地理本体结合起来,可以获得更为丰富的、更能反映空间关系在不同语言上下文中具体体现的组合关系;最后给出了一个空间信息的语法结构的基本框架。

All characters that have been used to delimit more narrowly defined species in other treatments of Chinese Clethra exhibit a strongly continuous pattern of variation from west to east across the range of the species in China (i.e., leaf size and shape, the number of secondary veins on each side of the midvein, anther size and shape); they also exhibit geographically correlated or seemingly random patterns, but without correlated gaps in character states among any two or more characters (i.e., style pubescence, corolla abaxial surface, stamen exsertion).
用来界定更狭窄定义的中国的Clethra的其它种的全部特征,从中国种的分布区的西部到东部,展示了一种强烈的连续变异的样式(如,叶大小和形状,中脉每边次脉的数目,花药的大小和形状);他们还展示出地理分布的相关或好像随机的样式,但是在任何2或更多特征状态间没有相关的特征间隔(如,花柱被短柔毛,花冠背面、雄蕊伸出)。叶大小与形状,在中脉,花药大小与形状的每边次脉的数量;也的他们展览好象地理上有相互关联或随机模式,但是没有有相互关联特征差距在任何2 特征或更多中说明即,花柱短柔毛,花冠背面,雄蕊exsertion。

From the point of view of geobotany, with the method of correlative factors of growth of plants, a countrywide theoretic ecological division was done for the introduction of Camptotheca acuminata and three kinds of areas of ecological preferent zone, ecological adaptive zone and ecological unadaptable zone were divided. With the theory of synecology, the characteristic on environment, constitution, life form spectrum, diversity, similarity of plots of communities were researched. Applying the method of species association, discrete distribution, indensity index, fractal geometry, etc. to research relations between the species of the communities, space distribution of Camptotheca acuminata, structure of age of Camptotheca acuminata, in different communities. Using the theories of autoecology, distibutons of seeds on land and growth of seedlings in vertical and horizontal directions, biomass of organ of Camptotheca acuminata were analyzed. On the opinions of conservation biology, the external and internal factors impressing Camptotheca acuminata were analyzed to research the mechanism of the endangered species, and with using of CTM Model, the future development direction of Camptotheca acuminata in different communities were forecasted, and. Standing on the position of resources ecology, discussing the regularity of camptothein in Camptotheca acuminata of different sites and seeding of different resources, also the the derive technics of camptothecin.

In general, this issue belongs to the category of environmental history. While when it comes to some specific issues, trace element in soil is the cut-in point to study the changes of Chinese ancient society. At the present time, such research method hasn\'t been applied in history studies domestic and abroad so far. Therefore, the studies of the paper are only exploratory and immature researches.Three issues are concerned here:lTrace element in soil under geographical environment and the Hun and the Hsienpei\'s levirate.
本文主要探讨地理环境下的土壤微量元素与中国古代社会变迁的关系问题;在总体上,这一专题是属于环境史的范畴;但在具体问题上,则是以地理环境下的土壤微量元素问题做为切入点,来研究中国古代社会变迁问题的;就目前的情况看,这种研究方法在国内外历史学的研究中尚无先例;所以,本文的相关研究只能是带有一些探索性的、不成熟的研究。

The appearance of the specific levirate custom existing in the Hun and the Hsienpei Tungusic in Han and Wei dynasties is the inevitable results of the laws of geographical environment and social development. Living in the high latitudes and dry cold inland areas, plus being heavily short of virtual zinc, a trace element in soil, lead to a high death rate of child-bearing age women. In order to guarantee a normal birth-rate, the Hun and Hsienpei Tungusic had to adopt levirate to ensure healthy child-bearing age women to give birth to offspring as many as they can.2 Trace element in soil under geographical environment and the cultural process of Huang-huai-hai Plain(the Yellow River, Huai River and Hai River ) in historical period.
本文具体的研究涉及三个问题:地理环境下的土壤微量元素与匈奴、鲜卑的"收继婚"问题:我认为汉魏时期匈奴和鲜卑族中特有的"收继婚"俗的产生,是地理环境和社会发展规律相互作用的必然产物;由于匈奴、鲜卑所处纬度高、气候干燥而寒冷的内陆地区,加之土壤微量元素中严重缺乏有效锌,因而造成了育龄妇女的大量死亡,以致为了保证正常的种的繁衍,匈奴和鲜卑不得不采取"收继婚"的婚姻形式,来确保健康的育龄妇女尽可能的去生育后代。

Smilax, there are the phylogenetic relationships and distributive pattern to be found based on the combined ITS and maiK. tree: 1 a clade with the African species (S. kraussiana) and Australian species (S. australis), being a sister group; 2 a clade with the S. zeylanica of sect. Macranthae and S. bona-nox of sect. China, the former from Southeast Asia and latter native to US, showing they are a sister species which is disjunctive between Asia-North America, similar to the species pair of S. hispida and S. sieboldii; 3 S. perfoliata from Indonesia being sister to S. ocreata of China and S. megacarpa of Indonesia, which are very similar to each other in morphology; 4 the three species from China (S. lanceifolia, S. perfoliata and S. chapaensis) and S.ovalifolia from Indonesia showing a 87-92% bts monophyletic clade; 5 S.bracteata from China and two species of Indonesia (S. leucophylla and S. sp.) forming a clade in the ITS tree; 6 S.

The reason included five aspects:①the effect of physical environment: the open geographical environment and barren soil urge the Greeks to look for development outward while the close geographical environment and advantaged condition for agriculture shaped the Chinese conservative thought and obstructed their steps of going out.②the advancing and blocking of the economic: the frequent trade offered an abundant living supply and open view while the self-sufficient agriculture with restraining trade rigidified the thought.③ the difference in politic institute and situation: the democracy polis of ancient Greece is exclusive in the ancient world. It shaped the atmosphere of freedom, democracy and adversary. While the monarchy in ancient China pursued the "united country" and shaped the atmosphere serving for politic and consolidating thoughts.④the guiding of traditional culture: the Greeks pursued freedom and wisdom and were curious about nature while the Chinese adored ancestor and obeyed the authority and prefer to pragmatism.
出现这种关系的原因本文从以下五点进行分析:①自然环境的影响:古希腊开放的地理环境和贫瘠的土壤种植条件促使古希腊人向外寻求发展,而古代中国封闭的地理环境和优越的农业环境阻碍了中华民族外出的脚步和开放的思维;②经济条件的推动与束缚:工商业发展的农业经济和自给自足的小农经济所创造的物质条件和对思维影响的差别是很大的;③政治制度和政治形势的差异:古希腊民主城邦制在古代世界是独树一帜的,它所营造的自由、民主的氛围和古代中国追求&大一统&的君主专制下为政治服务、思想趋向统一的氛围截然不同;④传统文化的引导:古希腊人在长期的城邦生活和参与海外贸易的生活中形成的开放、自由、对自然充满好奇、追求智慧等民族文化传统与中国保守崇古、讲究实用的文化传统形成了鲜明的对比;⑤思想家本身(来源:A58BC论文网www.abclunwen.com)目的不同:古希腊思想家为了变得智慧而获取知识,享受知识带来的乐趣,而古代中国思想家的一切动机都是为了&成化天下&、&以政裕民&服务。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
