This paper gives an account of the research that the authors conducted on the cyclic sequences, events and evolutionary history from Proterozoic to Meso-Cenozoic in the Sino-Korean plate based on the principle of the Cosmos-Earth System. The authors divided this plate into 20 super-cyclic or super-mega-cyclic periods and more than 100 Oort periods. The research focused on important sea flooding events, uplift interruption events, tilting movement events, molar-tooth carbonate events, thermal events, polarity reversal events, karst events, volcanic explosion events and storm events, as well as types of resource areas and paleotectonic evolution. By means of the isochronous theory of the Cosmos-Earth System periodicity and based on long-excentricity and periodicity, the authors elaborately studied the paleogeographic evolution of the aulacogen of the Sino-Korean plate, the oolitic beach platform formation, the development of foreland basin and continental rift valley basin, and reconstructed the evolution

The (2 + 1)-dimensional fifth-order KdV equation is an important higher-dimensional and higher-order extension of the famous KdV equation in fluid dynamics. In this paper, by constructing new test functions, we investigate the periodic solitary wave solutions for the (2 + 1)-dimensional fifth-order KdV equation by virtue of the Hirota bilinear form. Several novel analytic solutions for such a model are obtained and verified with the help of symbolic computation.

To understand the characteristics of ocean internal waves better, we study the dispersion relation of extended-Korteweg-de Vries (EKdV) equation with quadratic and cubic nonlinear terms in a two-layer fluid by using the Poincaré-Lighthill-Kuo (PLK) method which is one of the perturbation methods. Starting from the partial differential equation, the PLK method can be used to solve the dispersion relation of the equation. In this paper, we use PLK method to solve the equation and derive the dispersion relation of EKdV equation which is related to wave number and amplitude. Based on the dispersion relation obtained in this paper, the expressions of group velocity and phase velocity of the equation are obtained. Under the actual hydrological data, the influence of hydrological parameters on the dispersion relation for descending internal wave is discussed. It is hope that the obtained results will be helpful to the study of energy transfer and other internal wave parameters in the future.

2015年全国沉积学大会

作者： Ziliang Liu xianghua meng College of Energy Resources Chengdu University of Technology China University of Geosciences

Molar-tooth(MT) is an enigmatic carbonate fabric composed of variously shaped cracks and voids filled with a characteristically uniform,equant microspar. MT widely distribute in Mesoproterozoic and early Neoproterozoic strata, where void-filling microspar and preserved carbonate. Detailed petrographic examination of MT structures from the esoproterozoic Gaoyuzhuang formation, Jixian,permits interpretation of the microscale relationship between crack morphology and lithologic,and potentially rheologic, variability of the surrounding substrate by tracing the distribution of petrographically distinctive MT microspar. That examination suggests that grain size, substrate lithology,and substrate cohesion all play critical roles in the development of MT. By contrast,the presence of a wide range of MT morphologies within petrographically homogeneous substrates,and an apparent relationship between crack diameter and sinuosity,suggest that the void-forming process itself also effected the final morphology of MT. On this basis,we discuss the significance of MT in the analysis of ancient marine environment.

The authors have found in their studies many new genetic types of microtextures of bauxite. A sedimentological genetic classification of bauxites based on these features and a division of the microfacies types of bauxites formed in major microenvironments are proposed. Four kinds of sedimentary sequence of bauxitic sediments have also been recognized. On these bases, a generalized sedimentary model of Carboniferous bauxites in North China is presented, in which storm-turbidite currents play an important role in the formation and enrichment of bauxite deposits.

一、煤炭市场调控的基本原则煤炭行业处于国民经济的基础地位 ,对我国经济发展具有举足轻重的作用。通过对我国煤炭市场的集中度和壁垒度分析可知 ,我国煤炭市场具有卖方集中度较低、买方集中度较高 ,市场的进入障碍尤其是煤炭流通市场的进入障碍非常低的特征。这充分说明煤炭行业因目标市场具有相当强的局限性和自然条件的制约 ,比其它行业需承担更大的风险 ;同时 ,买方集中度较高说明了买方垄断仍在煤炭市场中起负面作用 ,为加强政府宏观调控提供了客观依据。煤炭市场调控的根本在于调控煤炭市场主体的行为 ,本质上在于调控煤炭市场主体结构 ,使之与宏观环境相协调。因此 ,进行煤炭市场宏观调控的基本原则如下 :1 煤炭行业结构高级化原则。这是调控煤炭市场的方向性原则 ,即煤炭市场的调控 ,应保证煤炭行业长期持续稳定发展 ,保证生产率提高的方向和后劲。2 煤炭市场发展动力原则。这是调控煤炭市场的条件性原则 ,即充分利用煤炭市场的社会需求、煤炭行业的科技进步和煤炭市场主体竞争的动力因素 ,并根据调控需要使煤炭市场动力机制充分发挥作用或抑制其作用。3 煤炭市场结构有序原则。这是测度性原则 ,即煤炭市场和煤炭行业结构的调整 ,应保持结构有序...
