松辽盆地南部岩性圈闭识别技术及效果

寻找隐蔽油气藏一直是油气勘探中的难题,我国东部吉林油田的中浅层已进入高成熟勘探阶段,油气勘探已由早期的构造圈闭勘探转变为现今的以隐蔽圈闭勘探为主的阶段。本文针对松辽盆地南部的西部前缘带三维连片工区及伊通地堑岔路河断陷,综合应用构造精细解释、声波曲线重构波阻抗反演、层序地层学、地震相及沉积(微)相分析、模型正演、地震属性分析、频谱分解及三维可视化等技术手段,所提供的多口探井获得工业油气流或有良好的油气显示,取得了较好的解释效果。     

水库淤积初步平衡问题

水库淤积平衡问题对于确定淤积危害程度、可持续利用标准等都非常重要。本文通过分析大量已建、在建和规划水库淤积情况,对水库淤积初步平衡后淤积变化趋势与设计淤积标准等问题进行了讨论和商榷。研究表明,水库淤积初步平衡后,兴利库容淤积发展仍然很快,库尾河床与水位抬升仍在继续,并未最终稳定。水库淤积平衡应该更加注重兴利库容淤积情况和库尾河床与水位抬升趋势,仅仅关注总淤积量变化情况是不够的。从区域长远利益考虑,大江大河上的水库设计淤积年限还应大大加长。     

苏里格低渗强非均质性气田开发技术对策探讨

鄂尔多斯盆地苏里格气田储集层具有低渗、强非均质性、中强压敏的特点，气井产能低，稳产期短。根据单井模拟及生产动态分析，气井低产量生产可以降低压敏效应的影响，加强气井低产量生产阶段的管理，有利于合理利用地层能量，提高井控外围低渗区储量动用程度；分层压裂、多层合采可以在纵向上充分动用气井控制储量，增加气井最终累计产气量和稳产时间；地质研究与地震相结合，是提高储集层预测精度和钻井成功率的技术关键；降低成本，争取优惠政策也是提高经济效益的有效途径。

The effect of home storage conditions and packaging materials on the quality of frozen green beans

Home storage is the final step of the frozen foods distribution chain, and little is known on how it affects the products quality. The present research describes frozen green beans (Phaseolus vulgaris, L.) quality retention profile during the recommended ‘star marking’ system dates, at the storage temperatures of +5, −6, −12 and −18 °C (along 1, 4, 14 and 60 days, respectively).

The quality profile was assessed by a simulation system. Simulations were set by a response surface methodology to access the effect of different packaging materials (thermal conductivities and thickness), surface heat transfer coefficient, and refrigerator dynamics (effect of refrigeration cycles at the different storage temperatures) on the average retentions of Ascorbic Acid, total vitamin C, colour and flavour.

Green beans quality losses along frozen storage are significantly influenced by temperature, refrigerator dynamics and kinetic properties. Quality is also highly dependent on packaging materials thermal insulation (e.g. at temperatures above the melting point). Temperature cycles inside frozen chambers have a long term effect, and at the higher storage temperatures (e.g. T>−6 °C) are detrimental to frozen green beans quality after shorter periods.     

Life Calculations for Header – PGV-1000 Steam Generator Connector Weld Joints under NPP Service Conditions

The procedure for calculating the life of header – steam generator connector weld joints is proposed. It allows for running out the material plasticity reserve upon static cyclic elastoplastic loading as well as operating conditions, local stress concentrations, and residual stresses after welding.     

Exceptions that prove the rule--Using a theory of motivated social cognition to account for ideological incongruities and political anomalies: Reply to Greenberg and Jonas (2003).

A meta-analysis by J. T. Jost, J. Glaser, A. W. Kruglanski, and F. J. Sulloway (2003) concluded that political conservatism is partially motivated by the management of uncertainty and threat. In this reply to J. Greenberg and E. Jonas (2003), conceptual issues are clarified, numerous political anomalies are explained, and alleged counterexamples are incorporated with a dynamic model that takes into account differences between "young" and "old" movements. Studies directly pitting the rigidity-of-the-right hypothesis against the ideological extremity hypothesis demonstrate strong support for the former. Medium to large effect sizes describe relations between political conservatism and dogmatism and intolerance of ambiguity; lack of openness to experience; uncertainty avoidance; personal needs for order, structure, and closure; fear of death; and system threat.
