斜长石环带结构与相干结构

本文采用耗散结构理论,论述了斜长石环带结构的成因信息,提出了晶体生长的动力学数学模型,并指出外界能源的供给对晶体生长和构型有着重要的影响。讨论结果表明,当能量供给体系的速率超过某一临界阈值时,就会发生大范围的相干振动现象,它将引起水压等参数的周期性变化。这样,在斜长石的结晶过程中可以形成一种典型的相干结构—韵律型环带结构。     

试论辽宁西部碳酸盐岩及碎屑岩的含水系统与富水结构

辽宁西部碳酸盐岩和碎屑岩的充水空间皆以次生空隙为主,其发育程度与分布受岩性层组和地质构造的综合控制。按综合控制条件,本区划分有富水结构、导水结构和阻水结构三类水文地质结构。在一个水文地质单元中,上述三类水文地质结构常组成一个具有特定排列、成生联系和水力联系的整体,本文称为含水系统。区内碳酸盐岩可划分出软硬相间可溶性岩组褶皱构造裂隙—岩溶含水系统、软硬相间可溶性岩组断裂—岩溶含水系统和层状弱面可溶性硬脆岩组断裂—岩溶含水系统三类,富水结构和导水结构的钻孔涌水量分别为500—5000m~3/d和10—150m~3/d。碎屑岩可划分出层状弱面软质岩组褶皱构造裂隙含水系统和层状弱面软塑岩组褶皱构造裂隙含水系统两类,富水结构和导水结构的钻孔涌水量分别为500—3000m~3/d和10—100m~3/d。

CHINA＇S REGIONAL DISPARITY IN 1981-2000：OPENNESS AND DEVELOPMENT OF NON-STATE-OWNED ENTERPRISES AND FISCAL DECENTRALIZATION

While China‘s economic growth has been impressive since 1978, regional disparity in terms of provincial per capita GDP has been increasing. On the other hand, this rapid but uneven growth was accompanied by China‘s deepening openness and structural reforms including the development of non-state-owned enterprises (non-SOEs) and fiscal decentralization. Based on quantitative analyses, this paper tries to explore the features of regional disparity in China and the relationships between regional growth and China‘s openness and economic structure reforms in the period from 1981 to 2000, The paper finds that the catching-up of the coastal region to the initially rich provinces, which are mainly located in inland areas, brought about a convergence of the growth pattern across provinces in the 1980s. The subsequent divergence in the provincial growth rates between the coast and the interior generated an enlarging regional disparity in China in the 1990s. The ever-faster growth in the coastal region was benefited by China‘s openness and the development of non-state-owned enterprises. The development of non-state-owned enterprises underlies the higher operational efficiency in the coastal region. Additionally, with the insignificant regression results, fiscal decentralization was observed to facilitate faster growth in the coast region. The findings justify the initiative of the “West Region Development Strategy“ and offer some policy implications for China.     

Annual variation in Calanus sinicus abundance and population structure in the northern boundary area of the Yellow Sea Cold Water Mass

The Yellow Sea Cold Water Mass （YSCWM） was suggested as an over-summering site of the dominant copepod species Calanus sinicus in coastal Chinese seas. Population abundance and structure were investigated by monthly sampling along three transects across the northern boundary of the YSCWM during 2009-2010. Results show that thermal stratification existed from June to October and that the vertical thermal difference increased with depth. Generally, total abundance was lowest in October and highest in June, and the female/male sex ratio was highest in February and lowest in August. Evident spatial differences in abundance were observed during the existence of the YSCWM. In June, total abundance averaged 158.8 ind/m~ at well-stratified stations, and 532.1 ind/m3 at other stations. Similarly, high abundances of 322.0 and 324.4 ind/m3 were recorded from July to August inside the YSCWM, while the abundance decreased from 50.4 to 1.9 ind/m3 outside the water mass. C. sinicus distribution tended to even out over the study area in September when the YSCWM disappeared. We believe that the YSCWM may retard population recruitment in spring and preserve abundant cohorts in summer. The summer population was transported to neritic waters in autumn. In addition to low temperatures, stable vertical structure was also an essential condition for preservation of the summer population. C. sinicus can survive the summer in marginal areas in high abundance, but the population structure is completely different in terms of C5 proportion and sex ratio.     

Interpretation of remote sensing of geological structures and prediction of gold mineralization in Mohe area and its adjacent region

The authors took the ETM ＋ multi-spectra data as the data information and correlation coefficient for each band and carried out their information volume statistics. According to certain criteria, the authors also determined the optimum band-combined image. The image clarity is improved by various enhancements and fusions method. Based on remote sensing geological interpretation in detail, the relationship between remote sens- ing geological characters and gold mine were analyzed systemically. Using all kinds of remote sensing structure information, combining other research data, the authors determined mainly ore-controlling ore structure. Several prospective areas of gold ores were determined and furthermore significant finding mine target areas was confirmed.

低渗透储层的微观特征对其宏观性质的影响规律——以榆树林油田扶杨油层为例

利用岩心物性分析、压汞曲线和镜下分析等资料,研究榆树林油田东16区块扶杨油层的宏、微观特征及二者关系.结果表明:研究区扶杨油层岩性为岩屑长石砂岩,普遍具有碎裂特征,主要孔隙成因类型包括微裂缝、粒间孔、粒内孔和晶间孔,微裂缝对孔隙度的贡献不大,但对渗透率的影响不容忽视.孔隙度主要受孔喉发育程度影响,孔喉半径越大,孔隙度越高.渗透率受反映连通程度的特征结构参数影响较大,二者呈正相关关系,且孔隙度越大,特征结构系数对渗透率的影响越大.退汞效率受特征结构参数影响较大,储层为中孔时,退汞效率随特征结构参数的增大而增大;储层为低孔或特低孔时,退汞效率随特征结构参数的增大而减小.该研究结果对改造低渗储层、提高采收率具有指导意义.
