In this paper, at first the appearance background electricity grid in the rural areas of west China, and its meaning as well as the concept and structure of DG technologies are resented, and a DG technologies mode of development in the rural areas of west China is given. The development ideas and the future development direction of DG in are compared and summarized. At last, the significance of DG in future development of the rural areas of west China is prospected and some problems to be especially considered in the domestic research on DG technologies are put forward. 展开更多

为了使飞机槽型大开口结构能够满足刚度设计要求,提出了一种对槽型大开口结构增加4个边梁进行刚度加强的方案,并构建了工程分析模型,与无开口结构模型的弯曲刚度及扭转刚度进行了对比,得到了两种构型的刚度比,进一步得到了满足一定刚度... 为了使飞机槽型大开口结构能够满足刚度设计要求,提出了一种对槽型大开口结构增加4个边梁进行刚度加强的方案,并构建了工程分析模型,与无开口结构模型的弯曲刚度及扭转刚度进行了对比,得到了两种构型的刚度比,进一步得到了满足一定刚度指标下的边梁加强面积计算公式,提出了飞机槽型大开口结构刚度设计流程,可以用于方案阶段的飞机大开口结构加强设计. 展开更多
