在教科书评价研究中,评价框架的逻辑周延性是重要的挑战。单纯从功能或者结构的视角来建立评价框架都存在着各自的问题,而将两者紧密关联的功能—结构视角则有助于连接评价主客体、提高评价的稳定性和实践性。在一个教科书设计研究的二... 在教科书评价研究中,评价框架的逻辑周延性是重要的挑战。单纯从功能或者结构的视角来建立评价框架都存在着各自的问题,而将两者紧密关联的功能—结构视角则有助于连接评价主客体、提高评价的稳定性和实践性。在一个教科书设计研究的二维框架基础上,根据教科书设计的核心问题和编制历程,建立了新的包含教科书"课程内容规划—教学支持—文本呈现"三层面的"功能—结构"分析的教科书通用评价框架(CIR-FS)。整个框架是从功能分析关联到结构性的"要素"与"连结"分析,从而形成对教科书功能和结构的紧密性表达。CIR-FS框架在与国内外几种代表性同类框架的比较中,展现出了更优的稳定性和开放性,为进一步发展教科书评价标准系统提供了重要的基础。 展开更多

[Objective] The aim was to explore function and efficiency of emergy input/ output of Hunan agricultural ecosystem to reveal relationship of human being with natural resources and environment. [Method] Emergy structure, function and efficien- cy of Hunan agricultural ecosystem were analyzed based on input/output data in Hunan Province in 2009 as per emergy theory. [Result] The structure characters of agricultural ecosystem were as follows: Hunan is characterized with traditional agri- culture, depending greatly on both human and animal labor. For industrial accessory emergy, chemical fertilizers make most contribution to the system, and agricultural mechanization is not satisfied. Furthermore, renewable ratio of industrial accessory emergy is lower, and development and potential of green energy is promising. In addition, prices of the products are lower, without consideration of contribution made by natural resources and environment. It also suggested that Hunan agricultural chain is short and added value of products is not high. In general, emergy output of farming and animal husbandry dominates and the prices are lower than those of forestry and fishery. The function of the system was as follows: With lower environ- mental load ratio, the system is overloaded by population and the index of sustain- able development was 5.96, suggesting that the system enjoys vitality and potential, but the economy is undeveloped and the pressure from natural resources and envi- ronment is not high. The emergy output ratio was a little lower than national level in 2009, suggesting Hunan agricultural production is extensive. [Conclusion] The re- search indicated that rapid increase of population should be controlled; surplus labor should be transferred; agricultural structure and products structure should be further adjusted; agricultural technology should be further developed; agdcultural mechaniza- tion and modernization should be improved. 展开更多

Recently, the researchers put their attention on the literature works on Virginia Woolf or James Joyce too heavily just because the skill of stream of consciousness is used through the novel completely. Choosing this novel by Japanese writer as an example is an experiment, because the stream of consciousness as a composing method has melted its impression into the modem novel. And in the researcher's opinion, regardless the traditional part, the researching focus should be shifted on the works written by nowadays writer. To begin this paper, there are four questions should be solved: First, the definition of stream of consciousness should be known clearly; another question is the structure analysis of structure of Hear the Wind Sing; secondly, compared with the mental space theory and blending theory by Fauconnier, how to judge the function of Three Phases of memory's direction on reading should be focused on; thirdly, the reason why readers meet the problem of barrier when they read the stream of consciousness novel, and how the memory helps to solve the problem should be study in this section. Fourth, the extra factors which support the function of memory will enhance the skill of reading the SOC novel and finally foreground the meaning. 展开更多

Innovative features of wind turbine blades with flatback at inboard region,thick airfoils at inboard as well as mid-span region and transversely stepped thickness in spar caps have been proposed by Institute of Engineering Thermophysics,Chinese Academy of Sciences(IET-Wind)in order to improve both aerodynamic and structural efficiency of rotor blades.To verify the proposed design concepts,this study first presented numerical analysis using finite element method to clarify the effect of flatback on local buckling strength of the inboard region.Blade models with various loading cases,inboard configurations,and core materials were comparatively studied.Furthermore,a prototype blade incorporated with innovative features was manufactured and tested under static bending loads to investigate its structural response and characteristics.It was found that rotor blades with flatback exhibited favorable local buckling strength at the inboard region compared with those with conventional sharp trailing edge when low-density PVC foam was used.The prototype blade showed linear behavior under extreme loads in spar caps,aft panels,shear web and flatback near the maximum chord which is usually susceptible to buckling in the blades according to traditional designs.The inboard region of the blade showed exceptional load-carrying capacity as it survived420%extreme loads in the experiment.Through this study,potential structural advantages by applying proposed structural features to large composite blades of multi-megawatt wind turbines were addressed. 展开更多
