大庆油田油气勘探“五五”工程的实践与效果

大庆油田公司确立的油气勘探“五五”工程的核心是立足油气勘探长远发展、统筹老区与新领域勘探,兼顾工程实施与地质研究、系统配套相关技术理论,内容是调整工程和投资结构、完善油气勘探地质理论、发展各项适用技术,目的是促进油气勘探寻求大发现、获得大突破。通过实施“五五”工程,勘探工作运行平稳,勘探成果殷实丰硕,勘探领域层次分明,对油气勘探工作的发展产生了巨大的推动力,确保了大庆探区油气勘探实施的效果。通过对油气勘探“五五”工程实践过程的深入剖析,认为在油气勘探中“思路决定出路、前置加载量是基础、新技术应用是关键”。     

炼油厂废水的最小化

石油炼厂作为用水大户，在水资源逐渐短缺、环境污染日益严重的情况下，实施废水最小化改造具有重要的现实意义。笔者以石油炼厂整个水分配系统年度费用最小为目标函数，提出采用回用、再生回用和再生循环3种措施减少新鲜水用量和废水排放量。利用超结构建模求解所得优化的水分配系统不但要满足各用水过程的需求，而且使排放的废水达标。给出的实例证明，所提出的方法更全面地考虑了废水最小化的机会，且所得结果可行、有效。

Category Norms as a Function of Culture and Age: Comparisons of Item Responses to 105 Categories by American and Chinese Adults.

Understanding how aging influences cognition across different cultures has been hindered by a lack of standardized, cross-referenced verbal stimuli. This study introduces a database of such item-level stimuli for both younger and older adults, in China and the United States, and makes 3 distinct contributions. First, the authors specify which item categories generalize across age and/or cultural groups, rigorously quantifying differences among them. Second, they introduce novel, powerful methods to measure between-group differences in freely generated ranked data, the rank-ordered logit model and Hellinger Affinity. Finally, a broad archive of tested, cross-linguistic stimuli is now freely available to researchers: data, similarity measures, and all stimulus materials for 105 categories and 4 culture-by-age groups, comprising over 10,000 fully translated unique item responses.

Orientation-based unique representation for planar curves and shapes

This paper presents an orientation-based representation for planar curves and shapes. The new representation can uniquely represent all types, of planar shapes, be it convex, nonconvex, polygonal, smoothly curved, or piecewise smooth shapes. It is based on a new parameterization, theabsolute integral orientation. This representation is invariant under translation and rotation. The absolute integral orientation is a parameter invariant under scaling. As a result, matching of similar shapes (i.e., determination of the relative orientation and the scaling factor) using the absolute integral orientation as the parameter is easier than using the arclength as the parameter. In addition, the new representation has the feature of adaptive sampling, making it more compact and efficient than arc-length-based representations.
