松辽盆地新站地区嫩江组三段孢粉-藻类组合及其环境

依据松辽盆地西南部新站地区嫩江组三段孢粉和藻类化石百分含量纵向变化特征,自下而上划分7个能识别水体盐度变化的孢粉和藻类组合:Cyathidites-Pinuspollenites-Dinogymniopsis组合,指示缩小的微咸水湖相沉积环境;Dinogymniopsis-Leiosphaeridia-Pinuspollenites组合,代表水域扩大的微咸水湖相沉积环境;Cicatricosisporites-Pinuspollenites-Botryococcus组合,代表水域缩小的淡水-微咸水湖相沉积环境;Dinogymniopsis-Chlamydophorella-Taxodiaceaepollenites组合,反映淡水与微咸水频繁交互变化的浅湖相沉积环境;Cicatricosisporites-Pinuspollenites-Pediastrum组合,代表水域缩小的淡水湖相沉积环境;Nenjiangella-Balmula-Cyathidites组合,代表水域范围较大的淡水湖相沉积环境;Cyathidites-Tri-lobosporites-Botryococcus组合,指示水域缩小的微咸水湖相沉积环境。

地层坍塌压力的计算及在新站地区的应用

新站地区地质情况比较复杂,在钻井施工过程中极易发生井塌等情况,严重者由于井塌而导致了新钻井被迫报废进尺。井壁不稳定问题已严重制约着新站地区的钻井作业,并带来了很大的经济损失。如何合理地计算地层坍塌压力,给出合理的钻井液密度,是新站地区最为关心的问题。首先通过岩石力学理论,建立起地层坍塌压力计算模型,并给出模型中的参数与测井数据之间的关系,进而利用新站地区的常规测井资料连续地计算了该区的地层坍塌压力,从而有效地指导了钻井施工,收到了良好的效果。

大兴安岭新六站地区龙江组火山岩特征及构造环境

大兴安岭新六站地区龙江组火山岩为一套亚碱性、中高钾钙碱性中性火山岩。稀土元素标准化图解呈右倾平滑曲线,Eu具弱负异常。微量元素具Rb、Ba、K、La富集,Nb、Ti亏损的特点。龙江组火山岩形成于早白垩世中期,火山岩来源于壳源物质的部分熔融,代表了松嫩地块与多宝山岛弧带碰撞拼合后的伸展环境。

Exploring Web News Translation The Problems and Strategy of Web News in Taiwan

Web news translation demands that translators work in a short time frame, and speed in transmitting information is vitally important in a highly competitive news market. However, they should still be concerned with quality control as the most important factor in grabbing the audience＇s attention. This paper uses statistical research to investigate American audiences＇ preferences for receiving news, and to identify the problems and questions of Web international news in Taiwan, focusing on three main news websites in Taiwan. The aim of this paper is to establish an argument that the translator could make a contribution to Taiwan＇s Web news production by using right strategies to improve the translation. By analyzing news websites in Taiwan and comparing new trends of Web news, this paper studies several strategies of Web news translation.
