特殊会话隐涵是发话人所要表达的实际意思或意图，语用预设是发话人对他的说话语境和受话人的认知语境的一种假定，是实施其言语行为所必须满足的适切条件；分析、推导特殊会话隐涵必须借助上下文语境，而分析、推导语用预设有时不必借助上下文语境。

It is deemed here that the legitimacy of power under the peculiar conditions of ancient societies was destined by the other world outside of human beings', such as religion, theology, etc. In ancient societies, the power and governance were justified by means of God's will, divine regulations, exceptional human power and exterior transcendentalism.

本文认为，在古代社会特有的历史条件下，古代社会中权力的合法性由宗教、神学等外在于人的彼岸世界所支撑，古代社会的权力，往往要借助神的意志或是神法规则，借助超人的力量和外在的先验秩序来赋予自身统治的合法性。

Firstly, we select features by using CHI distribution. Secondly, we cluster the selected features by using an improved method which based on density. In virtue of the sort distribution information, we reduce the number of features twice and the information lost few. Lastly, based on the sort of texts, we use the distributing of probability to express text with matrix. By using matrix norm, we realized the text categorization.

In this thesis, a series of complexes based on aromatic multicarboxylic acids have been successfully synthesized in solutions or under hydrothermal conditions. Their structure and properties are investigated.(1) Eight complex compounds have been synthesized and characterized by X-ray single crystal diffractive technology: The eight complexes are listed as following: [Cu242] complex 1 [Cd22(H2O)4]·4H2O complex 2 [Co(H2btc)(H2O)3] complex 3 [Co2(H2O)2]·H2O complex 4 [Ni22(H2O)4] complex 5 [Cu22(H2O)4] complex 6 [Co(H2biim)2(H2O)2](H2btc) complex 7 [Zn(H2biim)2(H2O)2](H2btc) complex 8 The structure of complex 1 is dinuclear complex resulted from weak interactions（0-D chain）; complex 2 is 1-D chain stucture result from interactions of water molecules; complex 3、4、5、6 are coordination polymers using hydrothermal synthses, where the first kind ligand is H4btc, the second kind ligand is phen and Co2+、Ni2+、Cu2+ as center ions, respectively. While the coordination enviroment of Co2+ is the same in complex 3, the coordination geometries around the Co atoms in complex 4 are obviously different because of the different reaction conditions. In complex 4, the 1-D chains are connected into 2-D layer through carboxy groups of ligand H4btc. The structures of complex 5、6 are 1-D chain stucture result from interactions of carboxy groups in ligand H4btc. Complex 7、8 are homeomorphy compounds. Either of them are linked to the 3-D chains through intermolecular hydrogen bonds. Each H4btc lose two protons and H2btc2- acts as negative electron balance.
