The great potentials for exploration of litho-stratigraphic reservoirs do not appear until new methods and technologies have been applied and in-depth understandings have been gained. In recent two or three years, big discoveries have been made in Jilin oilfield, in which 80 percent of reserves are found in some areas of thin sand-shale interbedding of its delta front. There still exist petroleum potentials amounting to 6×10^8 t for exploration in this area, especially in southern Songliao basin where the litho-stratigraphic traps will be more important domains and deserve extra attention. Hence, geologically speaking, this study on the hydrocarbon accumulation of litho-stratigraphic reservoirs in Songliao basin is of vital significance to exploration of the southern Songliao basin.

In this paper, the theory, algorithm, and experiment of automatic object detection and tracking are studied in depth. It is firstly pointed out that the essential of Mean Shift method is a special Newton-Gaussian method. A new method named Fast Mean Shift is established to stretch the conservative step of Mean Shift method. The convergence and validity of this new method are proved in theory. And it is also proved that the convergence speed of Fast Mean Shift is faster than that of Mean Shift. The contrast experiments of searching the maximum possibility density of random of data sets in plane and 3D space are done. The results show that this new method can reduce the iterations greatly. A new object tracking method based on Fast Mean Shift is built to improve the object tracking performance, which is shown in the face tracking experiment with the tennis sequence provided by the Ohio State University, and the car tracking experiment with the car sequence provided by Kalsruhe University. The face trcking experiment with highly noised images show that the object tracking method based on Fast Mean Shift has strong anti-jamming ability. A new fast color object detection technology based on characteristic color is established, which use characteristic color distribution to compute the characteristic color vector of any area in an image quickly. With the high performance search method, the fast object detection is achieved. At last, using object tracker based on Fast Mean Shift and color object detector based on characteristic color with the Kalman filter, PID controller, searial communication and other technologies, automatic object detection and tracking system with control system is built. The availability and anti-jamming ability of this system are verified by some object detection and tracking tests in different scenes.

Methods the family members of 160 psychotic patients who had finished treatment in hospital were surveyed in demands for education such as health idea,content and way.results although the family members had a little of health information,they were short of health information guidance.some of them were lack of enthusiasm in the recovery of the patients so as to misdoubt that mental disease could be under control for long.but they needed much in the content of health education, and individual conversation was a way they liked to choose.telephone consultation was welcomed,as well.conclusion health education should be stressed in depth and extent,so are the content and the way.more helps need to be given to family members.

采用问卷方式对160例住院治疗结束后的精神病病人家属进行健康获得观念、教育内容、方式需求调查。结果家属有一定的健康信息储量，缺乏较深层次的健康知识指导；部分家属不相信精神病可以得到长期控制，对精神病人的康复训练缺乏热情；对健康教育内容需求较多，教育方式多选用个别交谈，咨询方式以电话咨询最受欢迎。结论家庭健康教育需加强知识的深度和广度，重视教育内容与形式的研究，加强家属的心理支持，需要得到全社会的共同关注。

Firstly, most articles about Hong Kong by Taiwanese authors during 1950s and 1960s featured transients and refugees, revealing the tumultuous Hong Kong society in early 1950s. Secondly, in their writings between 1970s and 1980s, most Taiwanese writers either vented their thinking of the motherland or witness the moment of political transform and opening-up or directly throw themselves in the rising wave in Hong Kong of the pursuit of their Hong Kong and emotion identities, which offers insight into the social phenomena and the concerns over the future of the city. Thirdly, before and after Hong Kong's return to China in 1997, Taiwanese authors had in-depth observation and comprehension of the atmosphere and ambience in Hong Kong at the time. Lastly, in the new era after the return of Hong Kong, Taiwanese authors started to excavate, using their unique esthetic views and values, the pleb culture that can best represent the spirit of Hong Kong and in the meantime constructed the distinctive landscape of sense of taste and memory of Hong Kong beyond its skyscrapers.

This paper attempts to study those typical texts in detail,on the basis of the in-depth analysis of the narrative art and techniques of the 1940's narrative poems,mainly from four aspects:the lyric narration,imagery narration, dramatic narration,"moledicized" narration,so as to explore and appraise their historical contribution,values,functions and limitations in the modem poem history.In the narrative poems in the 1940s,the technique of"lyric narration" is embodied mainly in the high degree of artistic integration of "felling" and "polt".The lyricism is fully embodied in both structure and language,and generally through two ways:the lyricism of the dramatis personae and the lyricism of relaters or poet himselfThe narrative poets in 1940s have further developed the "mood" type of narrative poems(a kind of structure model of the modem narrative poem)which was created by predecessors.

本文试图在对有代表性的文本进行细致研读的基础上，对40年代叙事长诗的叙事艺术与策略进行深入剖析，主要从抒情化叙事、意象化叙事、戏剧化叙事、谣曲化叙事四个层面展开，以发掘、评判其在现代诗歌史上的历史贡献、价值、功能及局限等。40年代叙事长诗中的&抒情化叙事&策略主要体现于&情&与&事&的高度艺术融合，抒情形态表现在抒情结构与抒情语言方面；其抒情策略大体有两种方式：一是诗中人物的自我抒情，一是诗人自己或叙述人的抒情。40年代叙事诗人进一步发展了前人创造的&情绪型&叙事诗这种现代叙事诗的结构模式。
