气井泡沫排水剂的评价方法研究

用当前国内外测试起泡剂性能的几种方法对七种起泡剂进行了试验研究。大量试验数据表明:起泡剂的起泡能力依评价方法不同而有差异。在分析比较了几种评价方法的优缺点后,建议用气流法为主、辅之以Ross—Miles法对气井用起泡剂进行综合评价较为符合生产实际。     

When syndromal similarity obscures functional dissimilarity: Distinctive evoked environments of externalizing and mixed syndrome boys.

This research examined how syndromal approaches to assessment can obscure differences between children in the quality of their social interactions. Mixed boys (high for externalizing and internalizing problems) showed heterogeneity in the responses they evoked from others: For one subgroup, aggression and withdrawal evoked aversive responses from others, and even prosocial behavior evoked hostile peer responses; for the other, aggression and withdrawal evoked positive peer responses. Externalizing boys also showed heterogeneity in the patterning of their evoked responses. Within-group heterogeneity was not explained by boys' syndrome scores but was linked to their reactions to specific antecedent events. The results illustrate how a contextualized analysis of behavior can reveal distinctive social interactional patterns that underlie similar overall rates of problem behaviors.

Methodologies used for evaluation of video tools and algorithms in MPEG-4

MPEG-4 issued two calls for proposals requesting submission of algorithms and tools relevant to standardization of MPEG-4. This paper reports on the evaluation of tools submitted for evaluation in November 1995 and January 1996. Complete video coding schemes submitted in January 1996 are also covered. The goal of the evaluation was to cluster the tools according to the technical areas they address, to evaluate them according to the issues relevant to the standardization process, and finally to suggest areas of core experiments to improve a video verification model (VM) as soon as the VM becomes available. Altogether, MPEG evaluated 87 tools and 19 complete coding algorithms, most of them highlighted in this paper. During the evaluation, 19 areas for core experiments were identified. Each core experiment is targeted at different functionalities like compression efficiency, content-based coding, error resilience, scalability. This definition of core experiments caused close collaboration and supported mutual fertilization between organizations working on similar tools, which allowed the VM to progress much faster than expected.     

Shape detection with limited memory

A new approach to shape detection through the generalized Hough transform is introduced. The method is based on a limited memory implementation of the transform, that reduces its cost and makes it suitable for hardware implementation. The rationale of the method is that a shape is bound by a circle whose radius is, in most practical situations, much smaller than the dimensions of the image processed. This a priori knowledge can be used during the vote collection phase of the transform to guide flushing operations against a filled memory. The method is tested in the simple case of circles detection and in more practical situations of IC inspection.

油气田地应力可分为均匀和非均匀两类，相应的井眼和水泥环形状分别为圆形和椭圆形。文章应用有限元方法对不同地应力条件下水泥环形状对套管应力的影响进行了研究。得出结论认为：在均匀地应力条件下，圆形水泥环对套管受力是有利的，应在钻井过程中尽量保持井壁稳定;在非均匀地应力条件下，如果固井质量良好，那么椭圆形水泥环可使套管最大应力及受力不均匀程度有所下降，对套管保护有利，应当在设计与钻井作业中予以利用。另外，数值计算结果表明，在非均匀地应力条件下，套管偏心对套管应力载荷的影响并不大，但尽量保持套管居中仍是必要的。
