宝浪油田侏罗系三工河组浅水辫状河三角洲沉积模式研究

焉耆盆地侏罗系三工河组广泛发育由辫状河进积到湖泊中形成的辫状河三角洲。这种三角洲特征显著不同于其它三角洲,其主体是辫状分流河道和水下分流河道。宝浪油田含油层段主体为辫状分流河道,以心滩发育为主要特征,是典型的浅水缓坡粗粒辫状河三角洲沉积。     

哈得逊隆起下石炭统基准面旋回与储集层预测

依据基准面旋回原理和方法,综合利用哈得逊地区的钻井、测井、地震以及地球化学资料,在研究区下石炭统识别出1个Ⅰ型和3个Ⅱ型层序界面,将哈得逊地区下石炭统划分为3个中期基准面旋回：SC1、SC2、SC3,对应于早石炭世海侵的3个海进-海退旋回.SC1旋回以滨岸砂坝沉积为主,而SC2、SC3旋回发育潮坪沉积体系.研究认为,SC1旋回滨岸砂岩及SC2下降半旋回的潮间带薄层砂岩为有利储集砂体,是地层-岩性型油气藏的重点勘探目标.     

Classification of the effectiveness of combination treatments

According to FDA regulations, a combination drug is not efficacious unless each component contributes to the claimed effects. For a univariate endpoint, this implies that the combination at specific doses must be superior to each of its components at the same doses. More demanding is the property of synergy, in which the effect of the combination must be superior to the effect expected based on those of its components. If it is equal to those effects, it is additive, and if it is inferior, it is antagonistic. We give regions in the combination dose plane where these concepts are well defined. If the effect of the combination is greater than the greatest effect achievable by any of its components it is therapeutically synergistic. A combination can be antagonistic, yet its components can still contribute to the claimed effects. If it is additive, synergistic or therapeutically synergistic, its components must contribute to the claimed effects. We relate these concepts and provide designs and sequential procedures for determining whether a combination is therapeutically synergistic, synergistic, additive, antagonistic and contributing or antagonistic and non-contributing.     

指纹细节特征提取与剪枝

指纹图像经预处理后，由于各种原因，会产生数以百计的特征。为了图像匹配的精确和快速，提出一套在细化后的指纹点线图上提取细节特征并对其剪枝的方法，并根据细节特征的拓扑特性，设计了验证其可靠性的算法。通过实验，证明了该后处理过程在去除指纹图像伪特征方法面具有良好的效果。     

Problems in the hygienic rationalization of the therapeutic and prophylactic nutrition of industrial workers

Based on generalization and analysis of instructions and guidelines for therapeutical and prophylactic diets of workers, ways of its optimization were proposed, by using bifide-containing acid dairy products as a preventive agent against possible occupational diseases caused by occupational factors.     

国有大型军工企业科协组织机构设置研究与设想

在全党、全国认真贯彻“十六大”精神,全面建设小康社会的热潮中,各行各业审时度势,将发展作为第一要务,与时俱进,深化改革,不断开拓创新。国有大型军工企业科协如何顺应时代潮流,在建立完善现代企业制度的同时,进一步理清思路,构建精简、高效、合理的下属组织机构,充分发挥科协“四主一家”积极作用,是当前急待研究和解决的重要课题之一。1国有大型军工企业科协组织机构现状国有大型军工企业科协组织大都创建于改革开放前,机构设置带有较浓的计划经济色彩,如图1所示。科协下属组织机构一是按行政隶属关系设置的学组;二是按上级学会(主管局)…
