煤层物性测井评价方法初探

依据煤岩的赋存方式和结构特点，利用电阻率和井径测井资料在不同煤质结构的煤层所表现的差异性，建立了2个指标(即深侧向电阻率与微球电阻率之间的比值，井径与钻头之间的比值)对煤质结构进行了准确的识别。用多元回归的概率模型建立了煤岩镜质反射率的测井计算模式，其结果与已有的煤心分析数据对比，两者具有较好的一致性。在综合分析的基础上，对煤层的重要物性参数煤阶、煤质结构进行了测井评价。     

Visual evaluation at scale of threshold to suprathreshold color difference

Visual evaluation experiments of color discrimination threshold and suprathreshold color‐difference comparison were carried out using CRT colors based on the psychophysical methods of interleaved staircase and constant stimuli, respectively. A large set of experimental data was generated ranged from threshold to large suprathreshold color difference at the five CIE color centers. The visual data were analyzed in detail for every observer at each visual scale to show the effect of color‐difference magnitude on the observer precision. The chromaticity ellipses from this study were compared with four previous published data, of CRT colors by Cui and Luo, and of surface colors by RIT‐DuPont, Cheung and Rigg, and Guan and Luo, to report the reproducibility of this kind of experiment using CRT colors and the variations between CRT and surface data, respectively. The present threshold data were also compared against the different suprathreshold data to show the effect of color‐difference scales. The visual results were further used to test the three advance color‐difference formulae, CMC, CIE94, and CIEDE2000, together with the basic CIELAB equation. In their original forms or with optimized K_L values, the CIEDE2000 outperformed others, followed by CMC, and with the CIELAB and CIE94 the poorest for predicting the combined dataset of all color centers in the present study. © 2005 Wiley Periodicals, Inc.

大坝安全信息权研究

大坝原型观测数据本身包含了丰富的信息，内在反映了监测项目之间的某种客观关系，基于此，应用PCA法及PPA法建立了确定大坝安全评价信息权重的正分析模型，一方面能够对数据进行降维处理，另一方面能挖掘数据内在信息，提取指标的相对重要性；并基于最优化准则，建立了信息赋权整合模型，解决了多种数学方法计算结果不一致性问题，最大限度地保持原始信息的完整性。

Do High-Achieving Female Students Underperform in Private? The Implications of Threatening Environments on Intellectual Processing.

Stereotype threat research has demonstrated that stereotypes can harm student performance in the face of public evaluation by peers or an experimenter. The current study examined whether stereotypes can also threaten in private settings. Female students completed a math test in 3-person groups, which consisted of either 2 other women (same gender) or 2 men (minority). In addition, students either believed their performance would be broadcasted to their peers (public) or not (private). Results revealed that minority students performed worse than same-gender students in both public and private environments. This finding supports the concept of threatening intellectual environments and shows how far reaching the effects of stereotypes can be. The authors discuss these findings in relation to research on tokenism and to stereotype threat and its educational implications. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

管内装元件强化传热的技术经济评价

提出了一种管内装元件强化传热的技术经济评价方法，此方法综合考虑了强化换热器管内传热膜系数的提高和管内流体阻力的增大，与普通的管壳式换热器相比，所带来的投资费用和使用费用变化，这个变化量可用净现值增量△NPV来表示。根据△NPV值来评价强化传热技术，从而为强化传热技术的开发和推广及进行决策提供指导。
