Alkaline-surfactant-polymer （ASP） flooding using sodium hydroxide as the alkali component to enhance oil recovery in Daqing Oilfield, northeast China has been successful, but there are new problems in the treatment of produced crude. The alkali added forms stable water-in-crude oil emulsion, hence de-emulsification process is necessary to separate oil and water. The problems in enhanced oil recovery with ASP flooding were investigated in laboratory by using fractions of Daqing crude oil. The oil was separated into aliphatics, aromatics, resin and asphaltene fractions. These fractions were then mixed with an additive-free jet fuel to form model oils. The interfacial properties, such as interfacial tension and interracial pressure of the systems were also measured, which together with the molecular parameters of the fractions were all used to investigate the problems in the enhanced oil recovery. In our work, it was found that sodium hydroxide solution reacts with the acidic hydrogen in the fractions of crude oil and forms soap-like interfacially active components, which accumulate at the crude oil-water interface.

This paper presents a high-precision maneuvering target contour tracking method based on Kalman filtering algorithm for video, against to the requirement to express the target contour accurately in engineering , and the fact that presently most of target tracking methods in video are not precise, target is easy to lose. By compensating the priori state error in update process of Kalman filtering algorithm, the method in this paper can track the target contour which occasionally moves sharply, especially it is suitable for the condition that target outline is clear against background. This method provides an approach to get target contour as well as internal information precisely, and has practical value in engineering. By the analysis of experiment, when severe maneuvering of the target happens or in the environment where there is background contour interference, the method can still track the target contour accurately, in addition it is easy to implement and has good real-time performance.

《春秋》经文庄公十三年冬所书写的“公会齐侯盟于柯”,出场的人物只有“鲁公”与“齐侯”。但在作为一个事件指称的“柯之盟”,则在《公羊》、《谷梁》、《左传》之三《传》的释义传文中,鲁庄公、齐桓公、管仲、曹沫(刿、子)皆已出现。传文释义的主轴环绕在“齐桓伯(霸)业”上,但对于“伯”之为“伯”抑或“霸”上,则出现了观点上与褒贬上的分歧。其次,“曹沫(子、刿)”从经文的未书写,到传文中的出场,再到战国时诸典籍的被世人称颂,或与管仲并提,或被鲁仲连、荆轲视为人物的典型,“曹沫(刿)”在历史流传中正被后世塑其型,进而成为一篇传文中的“传主”,在书写文中有其自身的生命形态与叙事情节,已完全脱离了三《传》传文中的释义性格,这也正是《太史公书》中《刺客列传》之首篇《曹沫传》的书写意义。
