2、The automatic activation of emotion words measured using the emotional face-word Stroop task in late Chinese-English bilingual

摘要:In the current study, late Chinese-English bilinguals performed a facial expression identification task with emotion words in the task-irrelevant dimension, in either their first language (L1) or second language (L2). The investigation examined the automatic access of the emotional content in words appearing in more than one language. Significant congruency effects were present for both L1 and L2 emotion word processing. Furthermore, the magnitude of emotional face-word Stroop effect in the L1 task was greater as compared to the L2 task, indicating that in L1 participants could access the emotional information in words in a more reliable manner. In summary, these findings provide more support for the automatic access of emotional information in words in the bilinguals』 two languages as well as attenuated emotionality of L2 processing.

3、Bank Collapse Along the Three Gorges Reservoir and the Application of Time-Dependent Modeling

摘要:After the Three Gorges reservoir impoundment water level changed, the groundwater dynamic stress field and the rock mass stress field changed considerably. As the water level changes, wave erosion as well as rain storm, causes bank collapse to often occur along the reservoir area. This chapter aims to find the mechanism causing bank collapse and apply this type of information using models which can then describe these mechanisms for later research. In order to find out the relationships between bank collapse and bank width, slope angle, property of bank soil, and intensity of rainfall, some modeling tests were carried out and the results showed that the width of the bank is the main factor affecting bank collapse. Another conclusion is that the process of bank collapse can be characterized as time-dependent. It is proposed that the process be divided into four characteristic phases: surface erosion, shallow erosion, deep erosion, and termination of slope movement. Deep erosion is the key phase of the four, for which the velocity and scale of bank collapses can be calculated.

4、Ecosystem Management

摘要:Ecosystem management is to make adaptive management strategy based on full understanding the process of composition, structure and function of ecological system, and to restore or maintain ecosystem integrity and sustainability. Forest ecosystem management attempts to maintain forest ecosystem complex process, path and the interdependent relationship, and maintaining their function good, for sustainable forest management and forest ecological system, and establishing and developing comprehensive theoretical system of forest ecosystem and sustainable forestry management system and decision support system, method and technology system. Grassland ecosystem is the prairie land biological coupling with its survival in nature. Absorbing new achievements of science and technology, to build and to make the new grazing system unit perfect, and make it as the indispensable important component of modern agriculture. Desert ecosystem management needs to solve problems of harmonious interaction and the sustainable development of river basin, as well as the ecological water requirement of river basin security problems. Desert ecosystem management must adopt comprehensive ecological management measures in the process of management, give attention to utilizationUtilization and protection to optimize economic, social, and environmental benefits. Wetland surface interaction process and the system response, the succession of wetland ecosystemWetland ecosystem and its ecological effect, and the further research of wetland ecosystem function evaluation becomes scientific foundation to explain wetland process route and wetland ecosystem management. Lake ecosystem is affected by human activities. Controlling food chain control of biological on the basis of the classic and nonclassical biological control theory is one of the important measures to control eutrophication in lake. Aquatic plant restoration is also very important in the process of eutrophication in lake. We developed the marine ecosystem management system in China, including ocean space planning and Marine functional zoning planning, Marine nature reserve construction, fishing intensity control and the closed fishing rule, ecological restoration and resource conservation, maintenance management information system construction, and emphasize more on the ocean in terms of ecosystem management in new pattern. Driven by the interests of the market due to the economic benefit and production effect, ecological environmental benefits are neglected in agricultural ecological system. Using the ecology principle 「prevention and control of integrated system」 is the fundamental way for agricultural pest control.

7、Ethanol-Water-Derived Sucrose-Coated-Al₂O₃ for Submicrometer AlON Powder Synthesi

摘要:Fluffy and homogenous sucrose-coated-γ-Al₂O₃ structured precursor was prepared by drying ethanol-water sucrose/Al₂O₃ suspension, in which the ethanol content of 85 vol% was optimized. Using the C/Al₂O₃ mixture pyrolyzed from such precursor with 23.2 wt% sucrose, single-phase AlON powder was synthesized by two-step carbothermal reduction and nitridation method at 1550°C for 2 h and 1700°C for another 1.5 h. The particle size of the AlON powder was around 0.6-1.0 μm. Compared with those synthesized by the traditional approaches with mechanical C/Al₂O₃, Al/Al₂O₃, or AlN/Al₂O₃ mixtures, the synthesis temperature was reduced about 50°C, and the AlON powder was fine and exhibited good dispersity. Such superiority of this method was attributed to that the pyrolyzed carbon film on Al₂O₃ particle greatly restrained Al₂O₃ coalescence during the thermal treatment.

8、An Evaluation Study of Bank Collapse Prediction in the Three Gorges Reservoir Area

摘要:When the impoundment of the Three Gorges reservoir reaches a water level of 175 m, the reservoir banks along the main river course and its tributaries will have a total length of 5,311 km. Among them, the rock banks are 213 km, and the banks of unconsolidated soil and rock mixture are 249 km. Bank collapse is one of the main engineering geological problems in the Three Gorges reservoir area. In this chapter, using an extensive amount of data on bank collapse obtained through geological investigation, field measurement of the bank collapse parameters, and simulation analysis, we systematically explored the bank collapse types, parameters, and bank collapse prediction methodology. In the Three Gorges reservoir area, the typical bank collapses are wash and abrasion, toe-erosion collapse, rock break-off and slides, and landslide. The evolutionary processes, the distribution features, and the corresponding geological conditions of these bank collapse types are analyzed as well. Eigenvalue angles of the rock and soil masses, including underwater deposit eigenvalue angle θ, wash-abrasion eigenvalue angle α, and steady above-water eigenvalue angle β, are fully discussed in the chapter. Based on the exploration of the correlation between bank collapse prediction parameter and the composition of the rock and soil mass and the correlation between mechanical features and the hydrodynamic conditions in the reservoir, an innovative prediction method that is adaptive to mountain-river reservoirs like Three Gorges reservoir area, Bank-Slope Structure Prediction Method (BSSPM), is proposed. The analogical study of three water storage reservoirs for many years, a comparison of the predicted results with that of the actual happenings, shows that BSSPM has a good adaptation for bank collapse prediction of mountain-river reservoirs.
