疏松砂岩油藏大孔道定性识别新方法研究

疏松砂岩油藏在长期注水开发过程中,往往伴随着大孔道的出现,这严重影响了油藏水驱开发效果,制约了采出程度的进一步提高,因此,大孔道识别及有效封堵成为该类油藏急需解决的关键问题.通过研究分析,确定了影响大孔道从形成到发展的7种主要静态因素,以及标志大孔道形成的6种主要动态因素.将层次分析法及灰色关联法相结合,分别计算静态及动态因素的权重,建立了全新的大孔道定性识别模型.示踪剂监测结果验证了该方法的实用性和有效性.     

从作者性别批评视角看简·爱和吕蓓卡的人物形象差异

简·爱与《名利场》中的女主角吕蓓卡是英国维多利亚时期文学中两个具有同样独立反叛意识但被作者赋予不同命运结局的女人。从作者的性别视角去解读这两个传统女性形象的本质差异,能看出男女作者对女性反抗压迫行为的不同理解和价值判断,并能更好地发掘出被别的批评视角忽略或误读的文本内涵。

Decoration of disclinations by solidification-induced band texture and focal-conic texture for a low-molar-mass liquid crystal

Two decoration techniques, solidification-induced band texture decora tion and focal-conictexture decoration, have been established to exhibit the director field of disclinations in a low-molar-mass methacrylate liquid crystal. The disclinations with strength s = 1/2 and s = ±1 are observed by the two decor ation methods. For the solidification-induced band texture decoration, the molecular orientation is perpendicular to the direction of the band. While for focal- conictexture decoration, it has been proved by the results of IR dichroism that the direction of the director is parallel to the direction of the focal-conic. Therefore, the sketch map of the molecular director filed can be mapped according to the morphological pattern of the solidification-induced band textureor focal-conic texture.     

Photon emission of phagocytes in relation to stress and disease.

Phagocytes, the first-line cells of the body's defence mechanisms against invading pathogens, kill microorganisms by means of lysosomal degradative enzymes and highly toxic reactive oxygen intermediates. The reactive oxygen compounds are produced, in a process called the 'respiratory burst', by the NADPH oxidase complex in plasma membranes, and by myeloperoxidase in phagolysosomes after degranulation. These processes generate electronically excited states which, on relaxation, emit photons, giving rise to phagocyte chemiluminescence (CL). This paper describes the conditions for the measurement of CL, and reviews the activity of phagocytes from individuals undergoing stress or disease. The capability of phagocytes to emit photons reflects remarkably well the pathophysiological state of the host. In many cases even the magnitude of the stress, the presence of a pathogen in the body, or the activity of the disease can be estimated. Physiological changes, e.g. in the reproductive cycle, can also be predicted.

Experimental gout from alloxan in pigeons. Findings in the joints and serous membranes

Zusammenfassung Bei Tauben erzeugt intravenös gegebenes Alloxan bekanntlich Läsionen, die denen der Eingeweidegicht ähneln. Chemische und mikroskopische Untersuchungen zeigten eine große Menge von Uraten auf Perikardium, Peritoneum und Pleura. Die große Zunahme der Harnsäure im Blute, die von anderen Autoren kolorimetrisch festgestellt wurde, wird durch die Urikasemethode bestätigt. In der vorliegenden Mitteilung wird weiterhin über ein der Gelenkgicht ähnliches Bild bei alloxanbehandelten Tauben berichtet. Verschiedene Tierarten mit einem «ureotelic-proteic metabolism» zeigen nach Alloxan weder eine nennenswerte Harnsäurezunahme im Blut noch eine Gicht der Eingeweide oder der Gelenke.     

Polarized Emission of Molecular Film With Lanthanide (Ⅲ) Complex

1 Results In the coordination system by using complexation with organic ligand, the ff emission of lanthanide(Ⅲ) (Ln(Ⅲ)) is induced the excitation energy transfer form the organic chromophore under the light-irradiation. However, there are not so much number of reports to discuss the energy relaxation mechanism in such complexes with Ln(Ⅲ). Recently, we succeeded firstly to estimate the rate constant of the energy transfer between the ligand and Ln(Ⅲ) in Pr(Ⅲ)-phenanthroline analogs[1]. Here, we will di...
