The Liaonan metamorphic core complex （mcc） has a three-layer structure and is constituted by five parts, i.e. a detachment fault zone, an allochthonous upper plate and an supradetachment basin above the fault zone, and highly metamorphosed rocks and intrusive rocks in the lower plate. The allochthonous upper plate is mainly of Neoproterozoic and Paleozoic rocks weakly deformed and metamorphosed in pre-Indosinan stage. Above these rocks is a small-scale supradetachment basin of Cretaceous sedimentary and volcanic rocks. The lower plate is dominated by Archean TTG gneisses with minor amount of supracrustal rocks. The Archean rocks are intruded by late Mesozoic synkinematic monzogranitic and granitic plutons. Different types of fault rocks, providing clues to the evolution of the detachment fault zone, are well-preserved in the fault zone, e.g. mylonitic gneiss, mylonites, brecciated mylonites, microbreccias and pseudotachylites. Lineations in lower plate granitic intrusions have consistent orientation that indicate uniform top-to-NW shearing along the main detachment fault zone. This also provides evidence for the synkinematic characteristics of the granitic plutons in the lower plate. Structural analysis of the different parts in the mcc and isotopic dating of plutonic rocks from the lower plate and mylonitic rocks from detachment fault zone suggest that exhumation of the mcc started with regional crustal extension due to crustal block rotation and tangential shearing. The extension triggered magma formation, upwelling and emplacement. This event ended with appearance of pseudotachylite and fault gauges formed at the uppermost crustal level. U-Pb dating of single zircon grains from granitic rocks in the lower plate gives an age of 130±2.5 Ma, and biotite grains from the main detachment fault zone have ^40Ar-^39Ar ages of 108-119 Ma. Several aspects may provide constraints for the exhumation of the Liaonan mcc. These include regional extensional setting, cover/basemen

The current responses of a generation/collection (G/C) system based on dual micropipettes are simulated by the boundary element (BE) method, from which the collection efficiencies for various pipettes with different geometries are calculated. The influence of the shape of a dual micropipette on the collection efficiency, such as curvature and symmetry of the pipette, as well as the thickness of glassy band between generator and collector, is presented and discussed in detail. moreover, the simulation results have been tested using the experiments of potassium and sodium ions transfers facilitated by dibenzo-18-crown-6 (DB18C6) at the water/1,2-dichloroethane (W/DCE) interface. These results demonstrate that the BE method is an efficient and useful approach for the simulation of collection efficiency of symmetric geometries of dual micropipettes operating in the G/C mode under transport conditions of diffusion control. However, there are still some problems for the cases of asymmetric dual micropipettes, which show rather large differences between the values of simulated and experimental ones. This work also indicates that such an ionic G/C technique should have advantages in applications when the dual pipettes have symmetric geometries.

Industries that suitable for cluster innovation are often intensive in knowledge and technology, with high capital agglomeration; closely interact and corporate with each other through resources sharing. Its development is depend on many factors, such as technical reliability, human resources, its own growth potential, competition, market prospects, and the government policies, etc.. Aimed at clarifying the path selection mechanism of cluster innovation, this paper first analyze the connotation of cluster innovation and its inside factors＇ bonding relationship, then exploring the triggers and path forming dimensions of cluster innovation. Finally, it builds a path-selection model on cluster innovation, and discusses the characteristics of each side.

马克思价值概念作为政治经济学的理论基石,是马克思在清理西方价值形而上学的思辨理性中开辟出来的。它克服了价值与事实的对立,也克服了形而上学的思辨传统,进而把价值概念还原为现实社会的经济结构。其中,考察西方价值概念伦理学提问的理性激情,马克思看到了“世界历史进程中生气勃勃的精神”即劳动实体这种自在结构;发掘近代西方价值形而上学追求普遍主义理性价值的不归路,马克思指认了形而上学价值概念以现实阶级利益为基础的特有形式;克服黑格尔社会历史层面价值概念运动的内在规定,马克思确立了价值概念内在的人类劳动实体的普遍性、同一性、等同性和通约性。
