Attention and implicit memory in the category-verification and lexical decision tasks.

Prior research on implicit memory appeared to support 3 generalizations: Conceptual tests are affected by divided attention, perceptual tasks are affected by certain divided-attention manipulations, and all types of priming are affected by selective attention. These generalizations are challenged in experiments using the implicit tests of category verification and lexical decision. First, both tasks were unaffected by divided-attention tasks known to impact other priming tasks. Second, both tasks were unaffected by a manipulation of selective attention in which colored words were either named or their colors identified. Thus, category verification, unlike other conceptual tasks, appears unaffected by divided attention, and some selective-attention tasks, and lexical decision, unlike other perceptual tasks, appears unaffected by a difficult divided-attention task and some selective-attention tasks. Finally, both tasks were affected by a selective-attention task in which attention was manipulated across objects (rather than within objects), indicating some susceptibility to selective attention. The results contradict an analysis on the basis of the conceptual-perceptual distinction and other more specific hypotheses but are consistent with the distinction between production and identification priming.

PL 油田调整井合理生产厚度预测新方法

PL 油田含油井段长,单井钻遇厚度大,目前采用一套井网开发,处于中高含水期,面临着综合开发调整。应用油田相渗数据和原油高压物性资料,绘制不同粘度下无因次采油指数与含水率关系图版,将油田近年来调整井初期含水米采油指数校正到含水为0时米采油指数。在此基础上,回归生产厚度与无水米采油指数的关系,利用油田研究的合理生产压差结果预测不同生产厚度下油井初期产量,确定合理的生产厚度,为油田的分层系开发调整和调整井的射孔方案提供依据。     

底盘漏斗分段矿房法的应用与发展

底盘漏斗分段矿房法在赞比亚的穆富利拉铜矿、我国的赤马山铜矿及后沟金矿获得了实际而有效的应用。文中全面地分析了使用该法损失贫化率低,矿房顶板易于控制,生产率高,成本低,作业安全性好等方面的巨大优越性及今后的研究方向;指出在矿岩中等稳固的、倾角25°～54°、厚度6～20m、品位低的金属矿床中应用此法是一种技术上可行、经济效益显著、灵活性强的采矿方法,具有广泛的应用前景。
