An In Situ Testing Method for Analyzing the Changes of Active Groups in Coal Oxidation at Low Temperatures

This study details an in situ Fourier transform infrared spectroscopy analytical system that was employed to follow chemical variations in the functional groups on coal surface during the oxidation process at low temperatures. In the reported in situ Fourier transform infrared spectroscopy system, a special chamber was used to contain the coal powders, and a gas inlet tube and a programmable heater were used to simulate different reaction atmospheres and temperatures. The comparisons between in situ and ex situ Fourier transform infrared spectroscopy spectra indicate that the in situ Fourier transform infrared spectroscopy data offer a more accurate reflection of changes in the functional groups. The real-time changes of aliphatic hydrocarbon groups and oxygen-containing groups in a lignite coal sample were analyzed from 30°C to 220°C using in situ Fourier transform infrared spectroscopy. The experimental results indicate that the chemical variations in the functional groups are affected by their relative chemical activities. The results show that the presence of aliphatic groups on the coal surface varies with temperature. Over the range of 30–70°C the presence of these groups decreases, but then their abundance increases over the range of 70–180°C and finally decreases again when the temperature is increased to between 180°C and 220°C. With respect to oxygen-containing functional groups, three various trends were observed as the test temperature was varied. Our conclusion was that these variations are a function of the reaction activities of the various oxygen-containing functional groups.     

华南上扬子区奥陶纪特马豆克阶的海平面变化

在较为精细的生物地层学研究基础上,对位于华南上扬子区4条剖面的沉积相组合以及沉积相序列进行分析,建立上扬子区特马豆克期高分辨率相对海平面变化曲线。识别出10个沉积相,划分出3个沉积相组合,分别沉积于浅潮下带、深潮下带和页岩盆地带;识别出5次重要的海侵事件,分别发生在TS.1a早期、TS.1a晚期、TS.1c早期、TS.1c晚期和TS.1d晚期,其中TS.1c早期的海侵为特马豆克期最大海侵事件。通过与其他板块海平面变化曲线的对比,发现上扬子区海平面变化主要受全球海平面变化的控制。

严王之争与王世贞心态的发展变化

严、王之争不仅彻底影响了王世贞的政治命运，也从根本上影响了他后半生人格心态之发展。随着严、王之争的展开，王氏以文章垂名不朽的人生志趣逐渐确立；严、王之争也改变了王世贞的文化心态，庄禅思想对王世贞文化心态的渗透使其形成出禅入玄的人生态度。心态的转变使王世贞的眼光更开阔，对于复古与创新、尊雅与尚俗之间的关系理解得也更为透彻，这使他超越了前后七子的其他成员，成为复古派中转变最大也是影响最大的一位。     

Nonlinear-driven instability of dynamical plasma in solids: Emergence of spatially self-organized order and chaotic-like behavior

We analyze in detail the nonlinear kinetics of a carrier system in a photoinjected plasma in semiconductors under the action of constant illumination with ultraviolet light. We show that the spatially homogeneous steady-state becomes unstable, and a charge density wave emerges after a critical intensity of the incident radiation is achieved. It is shown that this instability can only follow in doped p-type materials. In bulk systems the critical intensity was found to be too high making the phenomenon not observable under realistic experimental conditions. However, a more efficient electron excitation can be obtained in low dimensional p-type systems, like some molecular and biological polymers, where the interaction may follow by chemical interaction with the medium. We show that for intensities beyond the critical threshold an increasing number of modes provide further contributions (subharmonics) to the space inhomogeneity. It is conjectured that this process could lead the system to display chaotic-like behavior. Received 8 July 1998 and Received in final form 6 May 1999

一份由财政部正式发布的,包括39项企业会计准则和48项注册会计师审计准则的中国新会计准则正式出台,并将于2007年1月1日起执行。新会计准则将带来“革命性的变化”,同时也表明我国会计标准与国际会计惯例接轨的进程中又迈出了可喜的一步。本文对新会计准则中的若干变化进行了介绍与评析,以期对实际工作中理解和执行新会计准则有所裨益。     

扶余油田水驱开发储层参数变化实验研究

为了研究扶余油田进入高含水阶段后储层参数变化规律,在该油田检24和检25两口井的不同层位选取具有对比性的岩芯共12块。根据测井解释渗透率,将岩芯按高、中、低渗层位分组。分别对测定的油水相对渗透率曲线、储层孔渗参数及孔喉结构变化进行了研究。对实验结果分析发现,经过长期水驱开发,储层油水相渗曲线,两相区变宽,水相相渗端点值变高,储层孔隙度和渗透率都有所增大。该研究成果对目前油田高含水、高采出阶段评估油田开发潜力,确定下一步挖潜方向具有重要意义。
