膏盐岩地层地质特征与录井技术

石油勘探实践和研究结果表明，许多油气藏的形成都与膏盐岩地层有关，也常与膏盐岩地层伴生，成功钻穿膏盐岩地层是钻井难题之一，录井技术成为钻进安全监测、膏盐岩地层准确预报的重要手段。针对上述情况，介绍了膏盐岩地层的主要类型、沉积模式以及与油气的关系，归纳总结了膏盐岩地层的录井技术经验，包括：在随钻录井过程中熟悉地质设计与邻井资料；在没有预测钻遇膏盐岩地层的情况下，通过钻井液中Cl^-的变化判定是否钻遇膏盐岩地层；预计钻遇膏盐岩地层时，使用饱和盐水钻井液；钻遇膏盐岩地层后观察盐岩是否以岩屑形式返出；同时，把握膏盐岩地层的岩性、岩性组合、层位、顶底界和厚度是非常重要的。通过S1井实例分析，论述了在膏盐岩地层中钻进时，防卡、防漏是录井人员监测和预报的重点。

基于滑窗结构的软输出维特比算法的实现

文章在对软输出维特比算法(SOVA)进行推导的基础上，分析了软信息的提取过程。同时从硬件实现的角度考虑，提出了一种基于滑动窗1：3结构的SOVA算法实现方案，该算法大大降低了算法实现复杂度和译码延迟，同时通过调整滑窗参数，可以取得与非滑窗SOVA算法几乎相同的性能。     

The role of experience in liking "read-to-drink" alcoholic beverages.

Ready-to-drinks (RTDs) are composed of an alcoholic component and a soft-drink base and are primarily consumed by a youth market. The authors explored whether liking and experience with an RTD soft-drink base predicts liking for the RTD. Participants (N=350) from ages 12 to 30 years sampled 3 RTDs and their respective soft-drink and alcoholic components. For milk- and fruit-based RTDs, liking for and familiarity with their soft-drink base was the best predictor of liking for and familiarity with the RTD itself. For the Coke-based RTD, familiarity with and liking for bourbon best predicted familiarity with and liking for the RTD. All of these effects were consistent across blind and nonblind testing. The authors' results suggest that where there is perceptual similarity between the RTD and its soft-drink base, these beverages may provide an easy transition into alcohol consumption for novice drinkers.

新型超微晶软磁合金FePCCuMoSi微观结构缺陷的正电子湮没研究

用正电子湮没方法研究了新型超微晶软磁合金的微观结构缺陷，样品选用的是在不同温度下退火的Ｆｅ８１Ｐ１２Ｃ３Ｃｕ１Ｍｏ０．５Ｓｉ２．５合金，结果表明，合金的微观结构构陷大小，密度随退火温度有规律地变化，这种现象可能与非晶的晶化过程有关。     

Modelling aerodynamic sound in the airways of a human body: A possible diagnostic tool

The sound generated aerodynamically by a pillow-like body simulating an obstacle in the human airway is observed through a soft wall from outside the duct. It is intended to provide a physical basis for an attempted medical diagnostic technique for detecting an obstacle by observing the sound during breathing. So far at least two kinds of sound have been identified: One is sound of the half-jet flow formed downstream of the obstacle, and the other is sound due to unsteady motion of the separation point on the curved surface of the obstacle. For simulating the flow condition downstream of the vocal cords during inhalation, cases with an obstacle at various positions relative to a jet flow are also examined. In this case, the sound due to the downstream obstacle exhibits a complicated dependence on the geometry and flow parameters. Nevertheless, increase in the sound, or more correctly, deformation in the sound power spectrum, due to the presence of an obstacle is detectable from outside, opening up possibilities of its use as a diagnostic aid.
