The relation between oil and water in reservoirs with low and ultra-low permeability is very complicated. Gravitational separation of oil and water is not obvious. Normal reservoirs are located in depression and structural high spot, oil and water transitions are located in their middle. Stagnation is the key fact of oil-forming reservoir in the axis of a syncline based on the research of oil, gas and water migration manner, dynamics and non-Darcy flow in the Songliao basin. In low and ultra-low permeable reservoir, gas and water migrate easily through pore throats because their molecules are generally smaller than the pore throats; but the minimum diameter of oil droplets is larger than pore throats and they must be deformed to go through. Thus, gas and water migrate in advance of oil, and oil droplets remain behind. Pressure differential and the buoyancy force in a syncline reservoir are a main fluid driving force; and capillary force is the main resistance to flow. When the dynamics force is less than resistance, oil is immobile. When the buoyancy force is less than the capillary force, a gravitational separation of oil and water does not occur. The reservoir in the mature source rock of a syncline area with the low and ul- tra-low permeability belongs to an unconventional petroleum reservoir.

The expression vector pBPC30, which carries the high molecular weight glutenin subunit (HMW-GS) 1Dx5 and 1Dy10 genes, was transferred into hexaploid winter wheat cv. Jinghua No. 1, Jing411 and Jingdong No. 6 ex-plants of immature embryos and immature inflorescence by particle bombardment. A large number of resistant trans-genic plants were obtained under the selection of herbicide bialaphos or phosphinothricin (PPT). Confirmed transgenic plants of T0 generation showed successful integration of HMW-GS genes and bar gene into the wheat genome. T1 generation of transgenic plants can resist 20150 mg/L PPT. Protein analysis of T2 seed by SDS-PAGE showed that HMW-GS 1Dx5 and 1Dy10 genes were well expressed in offspring seed of transgenic lines by co-expression with or substitution of endogenous 1Dx2 or 1Dy10. In one transgenic line, TG3-74, a new protein band between endogenous pro-tein subunits 7 and 8 (marked as 8*) of glutenin appeared, but endogenous subunit 8 (encoded by 1By8 gene) was ab-sent. Analysis of gluten rheological quality on seed proteins of 102 T3 plants showed that the sedimentation value of 5 transgenic lines (44.249.0 mL) was remarkably improved, 59.6%64.3% higher than that of wild type Jinghua No. 1 and Jingdong No. 6, similar to bread wheat Cheyenne (48.0 mL). Analysis of dough rheological properties of transgenic lines showed that the dough stable time of 5 transgenic lines range from 16 to 30 min, whereas the dough stable time of wild type was only between 37 min. Our research suggests that introducing novel HMW-GS genes into wheat is an effi-cient way to improve its bread-making quality.

福克纳短篇小说“干旱的九月”在叙事方面的一个显著特征是隐喻性的叙事语言。本文以“干旱的九月”、“流言”、“血色黄昏”、“尘土”这些代表性的隐喻为焦点,将它们放在历史、神化、宗教的语境中,从语义、语用、审美等方面研究其内涵与作用。笔者认为,“干旱的九月”是“秋天”的具象,隐含着悲剧的原型意象;“流言”是《圣经》中所昭示的罪孽;“血色黄昏”预示着人们酒神般暴虐与疯狂,而“尘土”则象征着“罪与罚”及“死亡”。这些隐喻在语义上相互交叉,相互关联,紧密围绕着“疯狂、暴力、死亡”的主题,形成了巨大的语义网络,使主题表现更加深刻,富有内涵。从审美功能来看,这些隐喻简洁凝练、言简意赅,富有哲理,同时又委婉、生动,富有诗意。

战争是英国新上任的桂冠诗人卡罗尔.安.达菲诗歌创作的主题之一。国内外学者大都聚焦于其诗歌所反映的性别、自我、身份等问题,而忽略了她的反战主题。达菲认为战争即悲剧。在"流星"一诗中,达菲采用魔幻现实主义的手法,让一位犹太妇人的亡灵打开尘封的记忆,以碎片式的叙事形式,借助"流星"、"戒指"、"强暴"、"弑婴"等象征隐喻,讲述了自己和他人在纳粹集中营所遭受的残害与蹂躏,揭露了战争的罪恶本质,表达了对人世间战火依旧不断,人们迅速遗忘了战争的残酷,继续淡漠生命的尊严所产生的深切忧虑以及对世界和平的渴望。诗中人鬼对话并非灵异巫术,而是诗人借助亡灵之口,表达反战的心声。

This paper presents an application of the hazard model reliability analysis on wind generators, based on a condition monitoring system. The hazard model techniques are most widely used in the statistical analysis of the electric machine＇s lifetime data. The model can be utilized to perform appropriate maintenance decision-making based on the evaluation of the mean time to failures that occur on the wind generators due to high temperatures. The knowledge of the condition monitoring system is used to estimate the hazard failure, and survival rates, which allows the preventive maintenance approach to be performed accurately. A case study is presented to demonstrate the adequacy of the proposed method based on the condition monitoring data for two wind turbines. Such data are representative in the generator temperatures with respect to the expended operating hours of the selected wind turbines. In this context, the influence of the generator temperatures on the lifetime of the generators can be determined. The results of the study can be used to develop the predetermined maintenance program, which significantly reduces the maintenance and operation costs.
