严重非均质油藏高含水期剩余油分布研究进展

目前，我国东部大多数油田在经过长期注水开发后己进入高－特高含水采油阶段，但油藏内仍然有约５０％的可采储量，它们的分布日趋分散、复杂，开采难度越来越大，其中一个最主要的原因是油藏（或储层）的严重非均质性，文章对国内外剩余油分布状况进行了详细分析。针对我国东部老油田的开发现状，从开发地质的角度出发，详细论述了严重非均质油藏剩余油分布及其动态预测的研究内容和方法，并指出了相应的研究思路和技术关键。重建适合开发后期的具有预测功能的储层地质模型，对稳定东部，改善油田开发效果，提高油田最终采收率具有重大的意义。

大强度举重训练对女运动员CK、BUN、Hb指标的影响

为了解大强度训练时女子举重运动员血中肌酸激酶(CK)、血尿素(BUN)和血红蛋白(Hb)的变化规律，对8名优秀女子举重运动员进行了连续2周的跟踪测试，观察发现：大强度举重训练对血清CK活性的变化产生显影响，而对血清BUN水平变化不大。整个测试过程中Hb水平略有下降。

Surface modification of Ti-45Al-8.5 Nb alloys by microarc oxidation to improve high-temperature oxidation resistance

Microarc oxidation(MAO)electrolysis plasma deposition was used to prepare Al_2O_3coatings on Ti-45Al-8.5 Nb alloys to improve high temperature oxidation resistance.The surface and cross-section morphologies before and after high-temperature oxidation,the chemical composition,and the phase identification of the coatings were investigated by scanning electron microscopy(SEM),electron probe microanalyses(EPMA),and X-ray diffraction(XRD).The results show that Al_2O_3coatings with a thickness of approximately 8μm can be obtained on the Ti-45Al-8.5 Nb alloys by MAO for 600 s.The samples with the Al_2O_3coatings exhibited better high-temperature oxidation resistance.A minimal weight gain of only 0.396 g/m~2after 100 h oxidation at 900°C was observed for the coatings formed with a deposition voltage of 400 V and using a duty cycle of 3%.The deposition mechanism of the Al_2O_3coatings and the effect of the MAO parameters are also described.     

Effect of cold rolling process on microstructure and mechanical properties of high strength β titanium alloy thin sheets

The microstructure and mechanical properties of Ti-3.5Al-5Mo-6V-3Cr-2Sn-0.5Fe high strength titanium alloy sheets prepared by unidirectional cold rolling and two-step cross cold rolling were investigated. Results showed that the β phase grains were refined significantly by cold rolling followed by solution treatment for a short time.Compared to unidirectional cold rolling, the short time solution treatment after two-step cross rolling could significantly reduce the non-uniformity of the microstructure of the alloy sheets. After aging treatment at 550 ℃,the anisotropy of the mechanical properties still existed in the unidirectional rolled sheets, and the tensile strength was highest along the rolling direction. After solution and aging treatment, the anisotropy of the mechanical properties of the two-step cross rolling process sheet was not obvious than unidirectional cold rolling,and alloy had good strength and plasticity matching.     

I ain’t afraid of no ghost

This paper criticizes the traditional philosophical account of the quantization of gauge theories and offers an alternative. On the received view, gauge theories resist quantization because they feature distinct mathematical representatives of the same physical state of affairs. This resistance is overcome by a sequence of ad hoc modifications, justified in part by reference to semiclassical electrodynamics. Among other things, these modifications introduce ”ghosts”: particles with unphysical properties which do not appear in asymptotic states and which are said to be purely a notational convenience. I argue that this sequence of modifications is unjustified and inadequate, making it a poor basis for the interpretation of ghosts. I then argue that gauge theories can be quantized by the same method as any other theory. On this account, ghosts are not purely notation: they are coordinates on the classical configuration space of the theory—specifically, on its gauge structure. This interpretation does not fall prey to the standard philosophical arguments against the significance of ghosts, due to Weingard. Weingard’s argumentative strategy, properly applied, in fact tells in favor of ghosts’ physical significance.
