Fluid environment for preservation of pore spaces in a deep dolomite reservoir

Well TS1 reveals many uncemented pores and vugs at depths of more than 8000 m in a deep Cambrian dolomite reservoir in the Tarim Basin, northwestern China. The fluid environment and mechanism required for the preservation of reservoir spaces have yet not been well constrained. Carbon, oxygen, and strontium isotope compositions and fluid inclusion data suggest two types of fluids, meteoric water and hydrothermal fluid, affecting the Lower Paleozoic carbonate reservoirs in the Tarim Basin. Based on simulation using a thermodynamic model for H₂O‐CO₂‐NaCl‐CaCO₃ system, meteoric water has the ability to continuously dissolve carbonate minerals during downward migration from the surface to deep strata until it reaches a transition depth, below which it will begin to precipitate carbonate minerals to fill preexisting pore spaces. In contrast, hydrothermal fluid has the ability to dissolve carbonate in deep strata and precipitate carbonate in shallow strata during upward migration. Based on the dissolution–precipitation characteristics of the two types of fluids, the ideal fluid environment for the preservation of preexisting reservoir spaces occurs when carbonate reservoir is neither in the CaCO₃ precipitation domain of meteoric water nor in the CaCO₃ precipitation domain of hydrothermal fluid. Taking the Lower Paleozoic carbonate reservoirs in the north uplift area as an example, the spaces in the deep Cambrian dolomite reservoir near well TS1 were seldom filled because thick Ordovician deposits blocked meteoric water from migrating downward into the Cambrian dolomite reservoir and because the Cambrian dolomite reservoir has been in the domain of hydrothermal dissolution since the Permian. The deep carbonate layers in basins elsewhere with a similar fluid environment may have high uncemented porosity and consequently have good hydrocarbon exploration potential.     

Family education support to rural migrant children in China: evidence from Shenzhen

Rural migrant children have become a fast-growing population in China as a consequence of the large-scale population flow from rural to urban areas. Besides the dual-structure hukou system, which restrains rural migrants from upward mobility, family capital also plays an important role in providing family educational support to rural migrant children. Using the data from P District and N District of Shenzhen in 2013, this paper explores the present status of three dimensions of family capital and five aspects of family educational support to Chinese rural migrant children, as well as the correlation between family capital and family educational support from perspectives of migration status (hukou), life course (children’s age), and school type. Constrained by inadequate family capital in multiple dimensions manifested by less education, lower income, and limited social networks, etc., parents of rural migrant children provide less family educational support in nearly every aspect compared with parents of urban local children. Among rural migrant children, those in private migrant schools receive the least support from their parents.     

朝鲜民族共产主义者在中国东北抗日斗争中的地位和贡献

自1910年朝鲜被日本强制"合并"以来,朝鲜爱国志士纷纷来到中国东北地区,继续坚持抗日民族革命斗争。1930年以来,朝鲜民族共产主义者根据共产国际"一国一党"的组织原则,大多加入中国共产党,在我党的统一领导下,肩负着"双重革命使命",与各族人民紧密团结在一起,进行了英勇顽强的抗日武装斗争。朝鲜民族共产主义者以其特殊的身份和地位,在中国东北抗日武装斗争中作出了突出的贡献,并逐步形成了以金日成为首的朝鲜共产主义运动的领导核心力量。这段历史是中国东北抗日革命史的一部分,是朝鲜抗日民族解放斗争史的主要内容,而且是现代中朝友谊史的光辉篇章。     

扎兰、阿巴额数考

在清代早期的布特哈打牲部落之内,索伦各牛录组成的"阿巴"与达呼尔各牛录编成的"扎兰",数目最初是不定的,随两族牛录数额的增加而变化。所谓三扎兰、五阿巴的格局,应是在康熙三十八年才出现的。扎兰与阿巴并非同类性质的概念,阿巴所指实为地域上的行政区划;索伦人在牛录之上的社会组织单位,应当与达呼尔人一样,都是扎兰。     

明清玉器种类与装饰题材

一．与收藏联系紧密的明清玉器对古玉的收藏,应该说从古玉诞生的那一刻就开始了。只是当时收藏的意义仅仅等同于拥有。把前人留下的优秀文化遗物进行系统地收集、整理、研究,以阐释特定历史文化下的思想意识、社会生活、工艺艺术等问题,开先河者当属宋人。

基于旅游者视角的目的地品牌权益测量模型：以皖南国际旅游区为例

本研究基于旅游者的视角构建旅游目的地品牌权益测量模型,并使用来自中国的经验数据对其进行检验和修正。研究发现：旅游目的地品牌权益包括4个维度：品牌知晓、品牌形象、品牌质量、品牌忠诚。其中,品牌知晓是品牌权益的基本来源,对品牌形象和品牌质量有显著直接影响;品牌形象是品牌权益的最重要维度,显著影响品牌质量和品牌忠诚;品牌质量显著影响品牌忠诚;品牌忠诚是品牌权益的核心概念,是品牌建设追求的重要目标。     

"文革史学"初探--以中国近代史研究为例

“文革史学”是指1966-1976年“文化大革命”期间中国“史学”的发展和演变的历史,它既是中国史学史、也是“文革”研究的重要组成部分。“文革史学”是动乱年代政治运动的特殊产物,是中国史学史上极为黑暗的一页,给中国史学蒙上了极大耻辱。它截断了中国史学的优良传统,并离群索居,与不断前进的世界史学背道而驰;中国史学成了政治史学、影射史学的代名词,失去了作为一门科学的独立性与尊严。     

今本大、小戴《礼记》编者误说清理

大、小戴《礼记》为戴德、戴圣所编,从《汉书》到孔颖达《礼记正义》都有定论。但自宋代开始,历代均有学者或对今本《礼记》为二戴所编表示怀疑,或提出“新说”。这些怀疑和“新说”虽然大部分遭到前人的否定,但他们提出的有些证据仍然没有被驳倒;近人洪业提出的几个疑点尚未获得令人满意的解答;还有一些学人未能吸收前人的研究成果,仍然在使用被证明为错误的说法。因此有必要对古今人在这个问题上的种种误说进行清理。
