Topos概念的提出(即elementary topos的公理化)是在研究了如下几类范畴之后:Grothendieck topos,集合的范畴S,以及集合论的布尔值模型。 Grothendieck提出用拓扑空间X上的set valued sheaf的全体做成的范畴Sh(X)作为推广了的拓补空间X,... Topos概念的提出(即elementary topos的公理化)是在研究了如下几类范畴之后:Grothendieck topos,集合的范畴S,以及集合论的布尔值模型。 Grothendieck提出用拓扑空间X上的set valued sheaf的全体做成的范畴Sh(X)作为推广了的拓补空间X,用以研究空间X上的上同调.他把拓扑的概念推广到小范畴(smallcategory)C上,称为一个site(或称为Grothendieck拓扑,参看第2节)。这样就可以考虑给出的site(C,J)上的set valued sheaf的全体做成的范畴Sh(C,J),用它来研究site(C,J) 展开更多

This paper introduces the origin of Inclusive Financial System, summarizes the basic theories and views on inclusive financial system development and poverty reduction from experts and scholars at home and abroad. The paper establishes a theoretical analysis framework which impacts poor family income gap by using exponential smoothing method. The government should improve the credit market in poverty- stricken area by the way of macro-management to establish inclusive financial system, to overcome the difficulty of poor farmers' credit, to make more poor families to obtain credit opportunities. 展开更多

Its history dates back to the second millennium B.C. The ancient history of Jiroft and its proximity to the River ofHalil Roud have attracted archeologists during the recent decades. So far various historical works have been unearthed from the region of which marble ones are especially noteworthy. Basically, marble works were used more commonly in central plateau of Iran than other ones. The marble works discovered in Jirofl region are only comparable with those from the recently excavation at Shahr-I Sokhta in Zabol. The scientific examination of such works may pave way to identify their internal structures and to compare them in terms of their provenance. The present study will focus on the characterization of marbles discovered in Konar Sandal, Jiroft. In addition to petro graphical studies, XRD and XRF investigations were used to identify the crystalline structures as well as balk chemical composition of the discovered marbles. The obtained results revealed that the major constituents of the discovered marbles in Jiroft were Ca and CaO. The structure of discovered marbles had orderly compact patterns resulted mainly from metamorphism conditions. This structure is actually Unsimilar to those from Shahr-I Sokhta. 展开更多

In this paper, the author uses literature data and logical analysis in the ',China Dream" background and discusses the opportunities and challenges of Chinese Wushu industry. The author points out that China's development should be directed to the development of the fusion of traditional Chinese culture, to help China establish an energetic, self-improvement image and the pursuit of harmony and common prosperity. The image of peaceful rise of a big country enhances China's international status and influence Martial Arts and Martial industrial development should focus on the rich cultural connotations, tap the cultural symbol it could develop, build martial arts industry brands through various media channels, government support and other ways to expand the widest range of consumer groups, and expand development of martial arts industry 展开更多

The practice of more than 30 years of building socialism with Chinese characteristics contains within it a five-step evolution: "functional thinking → government leadership theoretical guidance → hybrid structure → the people in the principal position"; in the course of the further development of the practice of building socialism with Chinese characteristics, the important responsibility and mission of Chinese Communists (exercising governance for the people) and the new expectations of the people (innovative practice) determine that its basic tendency should be to carry out reform and breakthroughs at three levels: "deep structures → core institutions → operational means," embodied in "structural adjustment → restructuring → change of methods →construction of order." 展开更多
