The geology research of carbonate reservoirs in Ordovician of Tahe oilfield showed that many large dissolved vugs and fractures were developed. The spread of the reservoir take on a very heterogeneous state. And the typical fractured-vuggy reservoirs was formed. According to the combination of the various spaces, the formation was divided into vuggy formation, fractured-vuggy formation and fractured formation. The research showed that development of the vug is relevant to the its position on the structure, the fractures, the water surface and the weathering surface. Multi-phase charge and recharge of the oil in the reservoirs resulted in the complexity of the fluid distribution. So the"Bottle Model"was brought forward to explain the movement of the water-oil contact. The special storage space and the complex fluid distribution lead to the unstability of the production and the complexity of the water cut. In order to explain the characteristic of the fracture-vug unit was brought forward and the basic principle and method of the partition of the fracture-vug unit was formed. The classification and evaluation of the units were performed according the reserve and energy. Based on the research of geology characteristic and the fluid flow in the reservoir the comprehensive numerical simulation plan of the fractured-vuggy reservoirs were established. Through the selection of the simulation unit, fluid flow type and parameter equivalent the triple media reservoir simulation model was established. Considering the practical application the model was resolved by the DKR decomposition conjugate grads method. Based on the fine reservoir description of Dsitrict IV of the Tahe oilfield the various space type were classified and combined together. The geology model of Unit S48 was constructed. Two typical single well model was established according to the geology and the dynamic phenomena. Finally the single well model and the Unit S48 were simulated by the triple media reservoir simulator. Via the local grid refinement and coarsening in the simulation good matchs were gained. Based on the results of the simulation the reserve distribution, percent of reserve produced in various space and the natural energy were analyzed. The fluid was storaged in the fractures and vugs mostly and more than 90% the produced oil came from the systems. The energy belonged to the active one. The results of simulation accorded with the fact and showed the validity and practicability the research and the simulator.

However, during New Trend '85, Gu Wenda differentiated himself from most artists of Chinese Painting of the time and showed his contemporary consciousness by experimenting on traditional ink painting materials and techniques. This brought out a new possibility for the contemporaneity of Chinese Painting. Since then, unremitting efforts have been made to "modernize" Chinese Painting through traditional abstract elements like ink-wash and Calligraphy. These efforts streamed into a new trend called "modern ink"(or "abstract ink","experimental ink") in late 1980's, though seemed not widely acknowledged for its resemblance to Abstract Expressionism of 1960's and 1970's American art. What is interesting is that while some artists are endeavoring to "westernize" their art, a new trend grouped as "Neo-literati Painting" appears with very traditional form and mood. This can be explained as a group of people's resistance to the reformation of traditional culture as well as their nostalgia to traditional ideals. However, this school tends to be artificial for the absence of the particular context, and the expression with traditional brushwork is also regionally limited. Of all the efforts of reformation, Chinese Painting that accordingly adopts the tradition heads the list because of the cultural identification of the big number of population and greater market as a result of the economic growth of China. Meanwhile, the immense conservative inertia of traditional Chinese culture can also be detected.
在"现代艺术"风起云涌的"85新潮"中,谷文达以传统水墨的材料和方法表达出不同于当时大多数中国画艺术家们这种文化心态和文化认知的现代意识,为中国画的现代性提供了一种方案;以水墨、还有选择中国传统书法的抽象因素等可能来进行现代性探索,一直是中国画连绵的努力,在80年代后期汇聚成"现代水墨"(又或曰"抽象水墨"、"实验水墨"),是中国画的又一流向,但是不是没有脱离60、70年代美国的"抽象主义"意义,反而还有了拾人牙慧之嫌,所以始终难以获得更大的认可和成功;很有趣的是,与此"西化"流向同时的,还有以非常传统的方式出现的"新文人画"潮流,或许可以把这看着是部分中国文化人在中国以西方为参照的新文化背景下对之的抵制,对传统理想的怀念和诉求,但由于已经失去了其语境和环境,"新文人画"显得娇情和造作,而且这种以非常地域化的传统笔墨语言来表现的方式也失去了更为普遍化的可能;反而是延续传统一脉的国画,由于有巨大的人数基础的本土文化的认同,在中国经济发展后有了更大的市场,所以还是蔚然为中国画的一大潮向,从这也可以看到中国文化承传的保守性的力量。

The histamine in the particles will increase the transmission capacity of capillary and the velocity of the tissue-fluid flow and the superficial shear stress of related mast cell will be increased, which will once again activate mast cells to discharge active substance. Part of the active substance will be absorbed by capillary and the other part will be passed by tissue fluid to a remote place and it will activate the mast cells and the capillaries there. The directional path of the tissue fluid is approximately the same as the meridian, which forms the phenomenon of feeling-along-meridian on macroscale.

Through difference significance tests and analyses, it finds that (1) man students more possibly form identity achievement, and woman students more possibly form identity foreclosure and identity diffusion; and (2) the difference of self-identity status between man and woman students is associated with various domains; and (3) self-identity status between man and woman students have some similarities that identity exploration has the same importance to both; and (4) grade-one is a period when students face up to more identity crises, and grade-two is key period of identity formation, and grade-three is a developmental period of identity that provides the basis for re-solution of the emergence of new identity crises in grade-four;(5) there is a gradually enhanced direction from lower self-identity statuses to advanced ones from grade-one to grade-three, but there is also a direction that reentry into the identity crisis by grade-four. It indicates that the identity achievement formation does not mean the end of development of self-identity and proves that there is a continuous MAMA cycle in self-identity development; and (6) that students self-identity status mainly is identity moratorium provides some evidence for which there is a Moratorium in student development, and which self-identity formation is not easy; and (7) the development of student self-identity is associated with various domains, what students pay most attention to firstly is vocation, secondly life philosophy, and lower interesting in political and religious domains in ideology; for relational domains, students pay more attention to dating and friendship compared to sex role and recreation domain.

In the first part of this thesis, Stress relaxation method set up in the software of DMA was used to perform the aromatic and aliphalic (D2192-BAPP) PI film stretching process. To study the optical anisotropies property to the light leakage from the crossed polarizers, we put the stretched samples into one set of crossed polarizers and as expected, the stretched PI films could reduce the light leakage at view angle of ±45 deg, and exhibited a visually observed compensating property of an A-plate. No color shift wasobserved, and the birefringence was very uniform. These results prove a uniform birefringence can be obtained by a stretched process for PI films.

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。
