准噶尔盆地腹部Z2井三叠系地层及沉积特征   总被引：1，自引：0，他引：1  

刘柏林  王启飞  阎泗民 《地层学杂志》2008,32(2):188-193

对准噶尔Z2井三叠系各组的岩性、电性特征进行了详细解释与描述,对各组的孢粉、大孢子组合特征展开了讨论,提出了该井三叠系地层划分为自碱滩组、克拉玛依组和百口泉组,且将其与邻区钻遇的三叠系进行了横向及纵向对比。在此基础上,通过对测、录井资料的精细解释,并借鉴前人的区域沉积相研究成果,探讨了该区三叠纪沉积环境。  相似文献

柯柏林 《地质与勘探》2008,44(3):91-94

针对无岩芯钻井地层时代划分的困难,文章通过对北京石炭系和二叠系层型剖面标志特征的分析,识别了岩石地层单位的分层标志特征,论述了钻井岩屑地质编录的要求和地层钻探特征,建立了太原组、山西组和石盒子组地球物理测井的物性标志特征,阐明通过岩屑地质编录结合物探测井资料能够较好地对钻井进行地层时代划分.  相似文献   

CHARACTERISTICS OF MAGNETIC LINEATIONS AND TECTONIC EVOLUTION OF THE SOUTH CHINA SEA BASIN     

吕文正  柯长志  吴声迪  刘建华  林长松 《海洋学报(英文版)》1987,6(4):577-588

Based on the analysis of new data of a total of 60 000 km, the authors propose a new spreading model of the tectonic evolution of the South China Sea Basin and suggest that magnetic anomalies in the Basin are the magnetic anomalies of a new type in marginal basins, that the tectonic development of the Basin can be divided into three seafloor spreading phases and that the southward migration of spreading ridge is related to the asymmetric spreading.  相似文献   

几种养殖鲍同工酶生化遗传的比较研究   总被引：8，自引：0，他引：8  

柯才焕  陈晓佳  周时强  王志勇  王艺磊 《台湾海峡》2003,22(2):173-179,T002

运用聚丙烯酰胺凝胶电泳对我国主要养殖鲍(皱纹盘鲍、盘鲍及九孔鲍)12种同工酶(LDH、ME、MDH、GPI、PGM、IDH、IDDH、SOD、EST、ODH、ADH、AAT)26个基因座位进行了分析．结果表明：EST、PGM可以作为区分三种(亚种)鲍的生化遗传标记；在所分析的位点中，未发现多态现象，表明三种养殖鲍杂合子缺失严重，其主要原因可能在于哑基因、近交与自然选择。  相似文献   

Embryonic and larval development of Babylonia formosae habei (Altena and Gittenberger, 1981) (Gastropoda:Buccinidae) on China''''s coast     

CHEN Yan  KE Caihuan  ZHOU Shiqiang  LI FuxueDepartment of Oceanography  Key Laboratory for Marine Environmental Science of the Ministry of Education  Xiamen University  Xiamen  China 《海洋学报(英文版)》2004,(3)

The development of embryos and larvae of Babylonia formosae habei living along the southeast coast of China is observed under laboratory conditions. The egg masses are laid by females on hard substrate at night and each capsule contains 100-500 eggs. Each egg is 250-280 mm in diameter. The first two cleavages of the embryo are meridional and equal, and a polar lobe is produced. Larval kidney, which only consists of a single cell, appears during the gastrula stage on each side of the embryo. The right tentacle develops prior to the left one. At 25-27℃, an intracapsulate veliger stage is reached about 4.5 d after deposition. The larvae hatch on the fifth day as swimming veligers with a shell length of 360 -500 mm. The newly hatched larva can ingest suspended algal cells from the water column and remains in the pelagic stage for 8-10 d. The newly settled juveniles are 900-1 200 mm in shell length.  相似文献   

Embryonic and larval development of Babylonia formosae habei(Altena and Gittenberger, 1981)(Gastropoda: Buccinidae) on China''s coast

The development of embryos and larvae of Babyloniaformosae habei living along the southeast coast of China is observed under laboratory conditions. The egg masses are laid by females on hard substrate at night and each capsule contains 100-500 eggs. Each egg is 250-280 mm in diameter. The fast two cleavages of the embryo are meridional and equal, and a polar lobe is produced. Larval kidney, which only consists of a single cell, appears during the gastrula stage on each side of the embryo. The right tentacle develops prior to the left one.

采用机械法、酶消化法和灌注冷消化结合机械法对孔鳐胰脏细胞进行分散,并以台盼蓝染色法测定活细胞率,评价细胞分散后的生长状态.在细胞分散后对孔鳐胰脏细胞用腺病毒载体和阳离子多聚物进行外源基因的转染.实验结果表明,灌注冷消化结合机械法可以获得较高的活细胞率,胰脏细胞可以正常生长并表达外源基因.  相似文献   

电子地图符号构图规律的研究     

谢超  陈毓芬  柯希林  柳佳佳 《北京测绘》2008,(1):35-37

根据电子地图屏幕显示与阅读的特点,应用地图视觉感受理论及地图符号学理论对电子地图符号的构图规律进行研究,是有效地改进电子地图设计所必需的。本文从电子地图符号构图规律研究的必要性入手,根据对电子地图视觉变量的理解,应用地图视觉感受理论和地图符号学理论,对电子地形图符号体系进行研究,同时根据符号库建库的需要,将所有符号分解为最小图元,提出了点状、线状及面状符号的构图规律。  相似文献
