中国南方志留系泥质岩盖层动态评价研究

在前人研究成果的基础上,针对目前天然气勘探研究的现状,总结确定了泥质岩演化阶段与封堵性能的对应关系。根据地质条件下岩石平均孔隙的直径与油气分子的大小，动态地评价了中国南方志留系盖层单剖面封盖条件，重点评价了从加里东期、海西期、印支期、燕山期到现今的川东北地区、黔中隆起及其周缘地区和江汉地区志留系盖层封盖能力的变化情况，认为这种评价可为天然气勘探提供理论依据。     

长距离气力输送系统与应用

气力输送虽然在许多领域中被广泛应用，如煤炭、粮食等，但其理论计算尚不够完善，许多计算公式还依赖试验数据。位于上海市浦东外高桥的上海海洋钻井工程公司，是东海油气勘探开发的重要基地。为东海油气勘探开发而建的气力输送油井水泥和钻井泥浆材料系统装置经过几个月生产运行，证明该系统装置运行安全可靠，集储存、于混、输送于一体，是目前国内外石油行业输送距离最长、技术水平先进、设备配置较好的气力输送系统。     

Materials and technology of Chinese jades dating to the Western Zhou period (1050-771 BCE)

Excavated jades dating to the Western Zhou period (1050-771 BCE) from the Xi’an area in Shaanxi Province, China, and contemporaneous jades in the collections of the Arthur M. Sackler Gallery at the Smithsonian Institution have been studied to learn about the jade and stone materials and how they were worked during the Western Zhou period. Materials identification was carried out using a combination of techniques such as Fourier-transform infrared spectroscopy and X-ray diffraction. Tool marks were studied using stereomicroscopy and examination of mold impressions using scanning electron microscopy. All of these objects were produced through simple processes involving solid drilling, riffling, and sharp point abrasion; and no evidence was found for the use of rotary tools for incising or sawing.     

中国石油物探五十年──谨以此文祝贺中国地球物理学会成立五十周年

经过五十年的艰苦历程，中国石油物探形成了一支具有相当技术水平、丰富工作经验和庞大工业技术体系的队伍，她已成为中国油气勘查工作中相对独立的、十分重要的技术手段和提供信息量最大的资料来源，并被认为必须把她放到“先行之先”“重中之重”的地位。五十年来中国石油物探可分为三个发展时期，不同时期有不同的发展特点，今天她已走上基本成熟的阶段，并已跻身于世界石油物探队伍的先进行列。但要使石油物探适应２１世纪中国石

A note on iterative marginal optimization: a simple algorithm for maximum rank correlation estimation

The maximum rank correlation (MRC) estimator was originally studied by Han [1987. Nonparametric analysis of a generalized regression model. J. Econometrics 35, 303-316] and Sherman [1993. The limiting distribution of the maximum rank correlation estimator. Econometrica 61, 123-137] from the econometrics point of view, and most recently attracted much attention from the classification literature due to its close relationship with the receiver operating characteristics (ROC) curve [Baker, 2003. The central role of receiver operating characteristics (ROC) curves in evaluating tests for the early detection of cancer. J. Nat. Cancer Inst. 95, 511-515; Pepe, 2003. The Statistical Evaluation of Medical Tests for Classification and Prediction. Oxford University Press, Oxford; Pepe et al., 2004. Combining predictors for classification using the area under the ROC curve. University of Washington Biostatistics Working Paper Series]. Compared with its nice theoretical properties and successful applications, the MRC estimator's computational aspects are not trivial. This is because the MRC objective function is neither smooth nor continuous. Therefore, the traditional Newton-Raphson type algorithm cannot be used to find the MRC estimator. As an easy solution, we propose in this article a very simple fitting algorithm named iterative marginal optimization (IMO), which guarantees a monotone increasing of the MRC objective function at each iteration step in a very efficient manner. We show via extensive simulation that the proposed IMO algorithm is not only computationally stable but also reasonably fast. Moreover, real data about the China stock market are analyzed to further illustrate the usefulness of the proposed.     

对当代中国哲学困境的思考

哲学的真正价值在于为人的生存和发展提供安身立命之本和可靠的支撑点.前苏联体制的束缚和教育产业化等因素的影响,是当代中国的哲学陷入困境和被边缘化的根源.深深植根于现实生活世界中,是当代中国的哲学走出困境的根本出路.
