Turkish Studies , 2012,
Abstract: Language is the most important part of culture. Because of that language is made up of writing and oral expressions, it implies that these expressions should be analyze in detail. In general, the people express theirselves orally in their daily lives. That’s why, oral expression should be made more effective. The goal of the study is to develop a measuring tool that can measure oral ability reliable and valid. The working group of this research has 342 students who get teaching formation education at Selcuk University of Konya City in Turkey. There are 230 female studens and 112 male students in this group. The students were wanted to evaluate the speak of the academic staff who did in previous lecture. Scale items were prepared by doing literatüre survey and getting comments of consultants. 111 items of the scale were reduced to 24 items after doing reliability and validity analyses and getting advices of consultants. In the scale, there are 20 items that can show positive situaitons and 4 items that show negative situations. The negative items of the scale are being pointed reversibly.To prove the validity of the scale, factor analyses that anatomize and confirm. The validity of scale was made by applying Cronbach alpha, Spearman Brown, Gutmann Split-Half Techniques, corrected item correlations and calculating the t-test values which are related with the 27 percent of up-down difference. After these, it was concluded that this scale is safe and valid. Dil, bir toplumun kültürünün en nemli unsurudur.

Abstract: 古气候是陆相湖盆层序地层形成的主要沉积动力学因素之一.古-新近纪柴北缘西段及周边地区古气候演化过程复 杂,目前就古气候演化过程还存在争议,利用地球化学方法对重点井的岩心和岩屑进行元素、TOC和碳氧稳定同位素测定.各 古气候指标之间的相关性分析表明:S r / B a、Rb / S r、S r / C a、TOC和氯离子含量可作为研究区恢复古气候的指标, δ 1 3C与δ 1 8O 不能指示出该区的古气候演化过程.重点井全井段的岩屑氯离子含量分析表明:柴北缘西段古-新近纪古气候经历了干旱- 潮湿-干旱的演化过程,从路乐河组到下干柴沟组上段沉积期古气候由干旱逐渐向潮湿的方向演化,呈现了7个旋回,湖盆水 体盐度降低,总体来说气候潮湿,水体为微咸水;从上干柴沟组到狮子沟组沉积期古气候从潮湿向干旱方向演化,呈现了1 2个 旋回,古水介质经历了微咸水至半咸水的演化过程

Abstract: 目前,井中磁梯度方法是深埋金属管线常用的探测方法之一,但是存在理论不够完善及缺乏定量分析方法等问题.研究 内容包括3个方面:(1)从无限长水平圆柱体的磁场强度入手,通过坐标系的转换,推导出地面探测和井中探测的磁场水平分 量、垂直分量的关系,进一步推导出管线的井中磁梯度公式;(2)根据磁梯度公式模拟出梯度值随有效磁化倾角及孔位的变化 情况;(3)通过对模型正演数据的统计分析确定了3种关系式:极值比与有效磁化倾角之间的关系式、管线的水平位置和磁梯 度极值间的孔深距离与有效磁化倾角的关系式、磁梯度极值的绝对值较大者和管线埋深之间的距离与极值距间的比值和有 效磁化倾角的关系式.这3种关系式组成了管线埋深及水平位置的估算公式.最后,通过实例来估算了管线的埋深和平面位 置,根据估算结果进行的正演结果表明了该方法的可行性

Abstract: 下扬子区是中国东部重要的含油气盆地区之一,其新生代伸展构造变形一直是下扬子新生代构造动力学的核心问题. 通过对下扬子海陆全区新生代断陷盆地结构与构造格局分析,明确了下扬子区伸展构造变形特征,探讨了变形成因机制及其 区域构造意义.区域构造分析表明,下扬子区伸展变形构造由一系列 NNE - NE - NEE走向的总体呈弧形展布的正断层构成,表 现为受伸展断裂系统控制的断陷结构,具有多向伸展特征,自南向北可分为江南、沿江-苏北-南黄海和南黄海北部3个构造 伸展区.有限元数值与构造物理模拟表明,受控于太平洋板块俯冲推挤传递至陆内的侧向构造作用力,下扬子块体南向蠕移, 区域上近南北向伸展变形,郯庐断裂右旋走滑,两者共同构成一个”右旋侧向扩展变形”系统.在区域构造上,大兴安岭-太行 山-武陵山重力梯度带以东的中国东部新生代伸展变形构造和盆地成因与古太平洋板缘边界条件密切相关.

Abstract: 九瑞矿集区成矿与燕山期中酸性侵入岩体关系密切,但对该区东雷湾矿床的地质地球化学研究还相对较少.对东雷湾矿 区中酸性侵入岩(花岗闪长斑岩、石英闪长玢岩)及其铁镁质包体进行了系统的锆石 U - P b年代学、矿物化学、岩石地球化学和S r - N d - P b -H f同位素研究,探讨其岩石成因.锆石 LA - I C P -MSU - P b定年表明:东雷湾中酸性侵入岩的成岩年龄为1 4 4.3~1 4 8.7Ma, 铁镁质包体的年龄为1 4 6.4~1 4 7.1Ma,与寄主侵入岩花岗闪长斑岩的年龄一致.东雷湾侵入岩属准铝质范围,岩石的 Mg # 较高 (4 2.5~6 8.0,平均5 6.0),并具有较高的相容元素含量,富集轻稀土,E u异常不明显,富集大离子亲石元素,亏损高场强元素.暗色 铁镁质包体呈细粒结构,常见针状磷灰石和钾长石斑晶.东雷湾样品的S r - N d同位素组成变化范围较小,初始8 7S r / 8 6S r比值位于 0.7 0 64~ 0.7 0 79,ε N d( t) 值 变 化 于 -5.8 0~ -3.3 1,t 2DM (N d) 为 1.2~1.4G a, 锆 石εH f( t) 值 为 -1 5.9~ -3.6. 样 品 的 2 0 6P b / 2 0 4P b( t)、2 0 7P b / 2 0 4P b( t)、2 0 8P b / 2 0 4P b( t)值分别变化于1 7.3 3 33~1 8.2 6 00、1 5.5 1 35~1 5.6 2 10、3 7.4 0 41~3 8.3 9 54之间.详尽 的元素和同位素地球化学特征表明,东雷湾铁镁质包体是由拆沉的加厚下地壳发生部分熔融,并在其上升过程中与地幔物质发 生相互作用,进而与花岗质岩浆混合过冷结晶形成的.该区侵入岩的形成很可能是因为加厚下地壳拆沉入软流圈地幔后发生部 分熔融,熔体与地幔橄榄岩相互作用后在上侵的过程分别形成了铁镁质岩石和花岗质岩石.

Abstract: 沉积物源对油气储层发育具有重要影响.为研究丽水-椒江凹陷西斜坡明月峰组上段物源的岩性组成及其分布特征, 选取4口钻井4个砂岩样品进行碎屑锆石 U - P b定年,并对陆上潜在物源区岩层(体)的岩性和年龄进行统计分析.结果显示: (1)样品中碎屑锆石以岩浆锆石为主,主要的年龄区间为1 2 5~9 0Ma、1 4 5~1 2 5Ma及1 7 0~1 4 5Ma,还有少量变质锆石,其年 龄区间为2 3 5~2 1 0Ma及20 8 7~16 5 3Ma;(2)陆上潜在物源区中以火山岩占绝对优势(1 7 3~9 4Ma),局部区域可能有较大 规模白垩系永康群沉积岩,而变质岩(>2 1 0Ma)和侵入岩(1 0 7.0~8 7.8Ma)仅零星出露.综合分析认为:研究区东北部明月峰 组上段的物源以永康群火山-沉积岩和九里坪组火山岩为主,含有少量晚白垩世侵入岩;西南部以九里坪组、西山头组火山 岩及元古代区域变质岩为主,侏罗纪火山岩为辅,这一区域可能更有利于优质储层的发育
