| 1 | 塔里木盆地典型砂岩油气储层自生伊利石K-Ar同位素测年研究与成藏年代探讨显示文摘塔里木盆地共发现 8套砂岩油气储层 ,对其中的 5套典型砂岩油气储层进行了自生伊利石K Ar同位素测年分析与研究。利用该项技术对其成藏史进行初步探讨是本次研究的主要目的。中央隆起下志留统沥青砂岩的自生伊利石年龄为 383.4 5~ 2 35 .17Ma ,表明志留系古油藏形成于加里东晚期—海西晚期 ;上泥盆统东河砂岩的自生伊利石年龄为 2 6 3.82~ 2 31.34Ma ,表明东河砂岩油气藏主要形成于海西晚期 ;库车坳陷依南 2气田 (依南 2井 )下侏罗统阳霞组砂岩的自生伊利石年龄为 2 8.0 8~ 2 3.85Ma ,表明油气充注发生在中新世以来 ;喀什凹陷阿克莫木气田 (阿克 1井 )下白垩统砂岩的自生伊利石年龄为 2 2 .6 0~ 18.79Ma ,表明中新世可能有古油气运移或古油藏形成 ;库车坳陷迪那 2气藏 (迪那 2 0 1井 )古近系砂岩中的伊利石主要为碎屑成因 ,不能用于进行油气成藏史研究 ,但该气藏白垩系砂岩的自生伊利石年龄为 2 5 .4 9~ 15 .4 7Ma ,表明可能为中新世成藏。本次研究表明 ,该项技术在塔里木盆地初步显示出较好的应用效果 ,具有较为广阔的应用前景。 | 张有瑜 Horst ZWINGMANN Andrew TODD 刘可禹 罗修泉 | 2004 | 地学前缘2004,11,4: | 55 |
| 2 | Biogenic production of DMSP and its degradation to DMS—their roles in the global sulfur cycle显示文摘Dimethyl sulfide(DMS) is the most abundant form of volatile sulfur in Earth’s oceans, and is mainly produced by the enzymatic clevage of dimethylsulfoniopropionate(DMSP). DMS and DMSP play important roles in driving the global sulfur cycle and may affect climate. DMSP is proposed to serve as an osmolyte, a grazing deterrent, a signaling molecule, an antioxidant, a cryoprotectant and/or as a sink for excess sulfur. It was long believed that only marine eukaryotes such as phytoplankton produce DMSP. However, we recently discovered that marine heterotrophic bacteria can also produce DMSP, making them a potentially important source of DMSP. At present, one prokaryotic and two eukaryotic DMSP synthesis enzymes have been identified.Marine heterotrophic bacteria are likely the major degraders of DMSP, using two known pathways: demethylation and cleavage.Many phytoplankton and some fungi can also cleave DMSP. So far seven different prokaryotic and one eukaryotic DMSP lyases have been identified. This review describes the global distribution pattern of DMSP and DMS, the known genes for biosynthesis and cleavage of DMSP, and the physiological and ecological functions of these important organosulfur molecules, which will improve understanding of the mechanisms of DMSP and DMS production and their roles in the environment. | Xiao-Hua Zhang Ji Liu Jingli Liu Guipeng Yang Chun-Xu Xue Andrew R.

| 3 | High school sports programs differentially impact participation by sex显示文摘背景:研究表明,参加体育活动可降低儿童和青少年肥胖的风险。学校是促进儿童和青少年参加体育活动的理想环境,但目前尚不清楚体育活动的'获得'和'选择'如何影响学生的参与度,也不清楚学校体育课的特点对学生参与体育的影响是否存在性别差异。本研究旨在评价高中体育运动项目的特点,并确定这些体育课程对男女生参与运动队的影响程度。方法:用电话采访的方式纵向调查了1,244名新罕布什尔州和佛蒙特州的学生。学生自述他们小学至高中阶段参与运动队的情况。通过调查高中职员了解体育机会。在本研究中,'体育机会'是指每100名学生所对应的学校提供的体育项目种类《选择)和学校提供的体育种类中不限制参加人数的体育项目的比例(获得)。结果:约70%的儿童参加了至少一个体育运动队,男生为73%,女生为66%。研究发现在性别和两个体育机会变量之间存在显著交互影响。控制小学生参与体育活动和其他协变量后,发现如果学校不限制最受欢迎的体育项目的参与人数,男生会参加更多的体育运动队(RR=1.12,p<0.01)。相反,如果学校提供广泛的体育项目,女生会参加更多的体育运动队(RR=1 47,p<0.001)。结论:前人研究表明,参加体育活动能带来许多健康效益。对公共卫生工作包括预防肥胖而言,学校体育课可能是一个重要而有效但未被充分利用的对象。要使青少年参加更多的体育活动,就应综合考虑学校体育项目的获得和选择。学校可运用不同策略,促使男生和女生更多地参加体育活动。 | Keith M.
