As one of the most important financial markets and one of the main parts of economic system, the stock market has become the research focus in economics. The stock market is a typical complex open system far from equilibrium. Many available models that make huge contribution to researches on market are strong in describing the market however, ignoring strong nonlinear interactions among active agents and weak in reveal underlying dynamic mechanisms of structural evolutions of market. From econophysical perspectives, this paper analyzes the complex interactions among agents and defines the generalized entropy in stock markets. Nonlinear evolutionary dynamic equation for the stock markets is then derived from Maximum Generalized Entropy Principle. Simulations are accordingly conducted for a typical case with the given data, by which the structural evolution of the stock market system is demonstrated. Some discussions and implications are finally provided.

The dynamic mechanism of liquid–glass transition for Mg₇Zn₃ alloy is studied by the molecular dynamics simulations. The temperature dependences of dynamic properties during the liquid–glass transition are investigated. Two relaxation processes are clearly observed near the glass transition temperature. The diffusivity deviates from the Arrhenius law after the melting temperature T_m and satisfies the power law before the dynamic singularity temperature T_c owing to the cage effect. The solid- and liquid-like atoms are defined according to the vibration characteristic of atoms. It is found that the solid-like atoms have higher local packing density, lower mobility and potential energy than the liquid-like ones. Based on the evolutions of solid- and liquid-like atoms, the atomic mechanism of dynamic liquid–glass transition is systematically elucidated, which is consistent with the potential energy landscape.

Unmanned Underwater Vehicle (UUV) formation system has an important role in the utilization of marine resource. In order to provide an efficient method to research modeling and simulation of UUV formation in the marine environment, the novel approach based on Multi-Agent Interaction Chain was proposed for the UUV formation system. Firstly, Multi-Agent Interaction Chain was analyzed, which mainly considered task and role of UUV in the formation, and the overall modeling process of UUV formation system based on Multi-Agent Interaction Chain was established. Then, the static structure of Multi-Agent Interaction Chain was researched focusing on Hybrid UUV-Agent model structure from the UUV-Agent State-Set and UUV-Agent Rule-Base which were the two aspects to strengthen reliability of interaction chain; the dynamic mechanism of Multi-Agent Interaction Chain was designed, which was focused on collaboration model and communication model through the Adaptive Dynamic Contract Net Protocol and KQML/XML/RTI. Finally, three experiments were established to verify the validity and effectiveness of proposed modeling approach for UUV formation system. Simulation results show the proposed model has good performance, which has important theoretical innovation and application prospects.

Imbalanced spatial development of China's economy leads to the transfer of industries between different regions. Such interregional transfer of industries not only reflects the dynamic changes of factor endowments between regions, but also is an important way to promote the development of underdeveloped regions. After the global financial crisis in 2008, along with the deterioration in external demand and expansion of domestic market, as well as driven by market forces and regional policies, China's interregional industry transfer presents new features and trends. Based on the reflections on relevant literature and cases, the author discusses China's industry transfer from three perspectives: why, where, and how to transfer industries, referring to three aspects: the impetus and resistance, scope and direction, as well as patterns and policies of industry transfer, so as to make a comprehensive and in-depth elaboration of the status quo, features and causes of interregional industry transfer in China.

Since the 1990s, China has gradually put forward the theories featuring new urbanization and coordinated regional development, and put them into practice. In the Report on the Work of the Government 2019, Chinese Premier Li Keqiang proposed that “We will promote coordinated development across regions and improve the quality of new urbanization”, drawing the public’s attention to new urbanization and coordinated regional development again. This paper first sorts out China’s research on new urbanization and coordinated regional development, mainly concentrating on the connotations, dynamic mechanism, strategic paths and models, and policy tools. Then it summarizes the major research results, including (1) the strategic theory and policy for spatial integration; (2) the theory and policy of main functional zones; (3) the urbanization theory and policy with city clusters as the major form; (4) the agglomeration theory and policy in the context of integration. And finally it proposes the major directions for further research: (1) innovation-driven cities and coordinated regional development; (2) compact cities with green, low-carbon, smart and humane features; (3) difficulties in the innovation of new urbanization system and mechanism; (4) leading research on the agglomeration theory and policy in the context of inter-connectivity.

Based on field investigation, we expounded the geological environmental conditions and basic characteristics of Taoyuan landslide in the paper. People excavated slopes at the foot of hillside, loaded on the slope, which formed a potential landslide. Under the unfavorable working conditions, such as storm or earthquake, the landslide would happen. Finally, feasible treatment measures (e.g., retaining walls and anti-slide piles) were put forward for Taoyuan landslide.

Based on the precise interpretation of 3D seismic data in the study area, it points out that Jiyang Depression with complex structures develops 4 kinds of structural systems of compressive, extensional, strike–slip and reversal structural systems. In this paper, it mainly researches on the types of compressive and overturned structural styles in Zhuangxi and Bogu 1 Well. It also studies anticlinal structural style of Chengdong. This study suggests that Indo-Chinese Movement in this area can be divided into two stages. The first stage occurred in the early- middle Triassic. During the clockwise revolution of the south part of the North China, the ancient Qinling Ocean got closed, which was between them; The second stage occurred in the late Triassic, it was when the North China and South China got collision, at the same time, the tip of Dabie Mountain wedged to the South China Plate, which caused the folds and the fractures in the cap of South China. It was when the Tanlu Fault Zone began to change from transform fault into inner continental shear zone. The stress in the two periods mentioned above, both produced the compression stress field in the depression, and the latter one caused the north-south compression in North China Block, which provided a driving force for the opening folds that were orientated to NWW or EW and thrust faults.
