东海盆地西南部地质特征与油气分布探讨

本文根据近3×10~4km地震和13口探井及其它地球物理、地质等方面资料,综合分析认为:东海盆地西南部与盆地其它部分在发育演化、构造运动、沉积环境等方面差异甚大。 盆地西南部(杭州湾—冲绳岛断裂以南地区)发育演化经历了断陷—坳陷—隆起—铺盖四个阶段。始新世末期的隆起在研究区演化史上有15～20Ma的沉积间断、剥蚀。这段历程,盆地其它部分未曾经历。其次是区内始新世末期抬升运动,致使始新统及以下老地层受剥蚀,仅始新统最大剥蚀量达1000m,这是盆地内绝无仅有的。第三是第三纪以海相沉积环境为主,特别在始新世,为海侵高潮,海城宽阔达8000km~2,这时盆地东北部正接受陆相沉积。研究区中部(北东向)可能存在超压泥岩及多套生油岩系,应为有利生油气区。研究区可能是盆地最有油气远景地区之一。     

压水堆硼稀释事故的计算

一、概述核电厂压水堆的初始过剩反应性是通过控制捧、固体可燃毒物和溶解在主回路冷却剂中的硼酸等三种方式联合控制的。随着反应堆的燃耗和裂变毒物的积累,堆的过剩反应性不断减少,需要通过化容系统,控制硼酸的浓度来进行补偿。如果化容系统发生故障或操作员误操作,就会给回路注入无硼或低于规定浓度的补给水,给反应堆引入正反应性,造成硼稀释事故。按核安全法规的要求,应对换料、冷停堆、热停堆和启动等工况进行计算,并要求在这些     

多丝正比室中电子的最大漂移时间

多丝正比室中电子的最大漂移时间是逃逸门电路中的一个重要参数。这个参数的选择将影响逃逸门工作方式的多丝正比室的整体性能。通过实验测量得到了多丝正比室中电子的最大漂移时间的实际值和最大漂移时间随多丝正比室工作状态的变化，测量结果在实际中得到应用。     

表面稳定模式铁电液晶的电光特性测试

采用一种改进的高分子膜摩擦定向法成功地实现了表面稳定模式铁电液晶的光学双稳态，对比度大于１４０，响应时间达１００微秒。     

Gelling of alginate fibres

Equipment was developed to measure the time for complete gelling of sodium alginate fibres in calcium chloride solution, taken as the time to achieve maximum tensile strength. The effects of fibre diameter, alginate concentration, alginate composition and calcium chloride concentration on gelling time were investigated. A diffusional model, developed to predict the gelling time, agreed with experimental results except for the effect of calcium ion concentration which was modelled empirically.

油田开发经济运行质量研究与应用

提出了油田开发经济运行质量的研究方法和技术思路。对胜利油区几种典型的油藏类型进行了经济运行质量评价。以老河口油田桩106块为例，提出了提高油田经济运行质量的三条基本途径，取得了较好的实际应用效果。     

波在PTL介质中传播的旅行时反演

本文对Byun(1990)的横向各向同性介质的旅行时反演方法作了两点改进:其一是根据优化后的V_r值计算一个初始的F值,然后再根据这个初始值进行最小均方误差分析;其二是对初始值进行优化分析时,提出用测量值(或由式(4)和式(10)计算的理论值)作为实际值进行拟合,而Byun的方法是用式(11)的计算来得到一个实际值。理论模型证明:本文所述方法有一个比较宽的适应性,而Byun方法只在弱各向异性时才可以得到较精确的结果。     

Applicant reactions to face-to-face and technology-mediated interviews: A field investigation.

This field study examined applicant reactions (N = 802) toward face-to-face as compared with technology-mediated interviews (through videoconferencing or by telephone) for 346 organizations. Face-to-face interviews were perceived as more fair and led to higher job acceptance intentions than were videoconferencing and telephone interviews. Perceived interview outcomes were higher with face-to-face and telephone interviews over videoconferencing. Self-monitoring moderated the relationship between interview medium and perceptions of fairness. Specifically, this relationship was (a) positive for face-to-face, (b) negative for telephone, and (c) nonsignificant for videoconferencing interviews. Moreover, the number of offers an applicant received moderated the relationship between interview medium over, and perceived fairness. The relationship between number of offers and perceived fairness was positive for face-to-face and negative for technology-mediated interviews.
