炉膛水冷壁高温腐蚀原因分析及治理对策

湖北汉川电厂1－3号机组燃烧区域水冷壁管普遍发生高温腐蚀。1－2号炉由于运行时间较长，表现的更为严重，1号炉由于高温腐蚀而泄漏的管壁厚度仅为1mm左右，严重影响机组的经济、安全与稳定运行。经多方面考察与研究，在分析高温腐蚀的机理上，制定出相应的治理对策，为今后的维护、维修、调试及运行作参考。

裂缝—孔隙型双重介质应力敏感模拟试验研究

在上覆压力75MPa、地层温度120℃、地层压力30MPa和水饱和度下的全直径全模拟降压开采试验揭示了裂缝—孔隙型双重介质由于生产压差的增大所导致有效上覆压力的增加而使裂缝高度减小所造成的地层气相渗透率的损害规律:渗透率越高,渗透率的损害越大。在此基础上,作者提出了不同类型储层的临界生产压差。

When Do Visual and Verbal Memories Conflict? The Importance of Working-Memory Load and Retrieval.

Examinations of interference between verbal and visual materials in working memory have produced mixed results. If there is a central form of storage (e.g., the focus of attention; N. Cowan, 2001), then cross-domain interference should be obtained. The authors examined this question with a visual-array comparison task (S. J. Luck & E. K. Vogel, 1997) combined with various verbal memory load conditions. Interference between tasks occurred if there was explicit retrieval of the verbal load during maintenance of a visual array. The effect was localized in the maintenance period of the visual task and was not the result of articulation per se. Interference also occurred when especially large silent verbal and visual loads were held concurrently. These results suggest central storage along with code-specific passive storage.

Learning Motion of Dexterous Manipulation For A Pair of Multi‐DOF Fingers With Soft‐TIPS

This paper shows that a pair of dual multi‐DOF fingers with soft‐tips can learn iteratively a desired periodic motion of manipulation of an object if sensory feedback signals are designed adequately. It is shown that dynamics of the overall fingers and object system satisfy passivity but residual error dynamics for a given periodic posture of the object and a fixed value of contact force satisfy output‐dissipativity only in an approximate sense. Numerical simulation results are presented which show that the pair of fingers manipulating an object is capable of learning iteratively a variety of dexterous motions with a good performance.     

Effect of firing atmosphere on air-fireable glass-free electrically conductive thick film

The firing atmosphere (air, oxygen, and argon) was found to affect the electrical and mechanical properties of an air-fireable electrically conductive glass-free silver-based thick film. For the optimum firing temperature of 930°C, air results in the lowest resistivity, but a minor amount of pinholes; oxygen results in the largest thickness, the smoothest surface, and no pinhole; and argon results in the highest resistivity, large pinholes, the smallest thickness, vanishing of macroscopic parts of the film, and the poorest scratch resistance. Argon gives higher resistivity than air or oxygen at essentially all firing temperatures.
