汉诗作为与唐人交往的重要手段,是衡量古代东亚国家国际化程度和文化水平高低的重要指标,在古代东亚文化圈中具有特殊的文化功能。El本汉诗起源于七世纪中期,通过吟咏汉诗,中日文人们能够进行一种超越时空界限的抽象的意境交流,展示出东亚文人的文化共性。. 相似文献

In order to meet the curative effect, the glove of the flexible medical orthosis was designed to use nylon/spandex and polyester/spandex covered yarns to knit the glove by parts. For the purpose of confirming the best heat setting technology of the glove knitted by multicomponent materials, different heat setting technologies with different temperature and time were tested on the nylon/spandex and the polyester/spandex knitted fabrics. And the effects of the heat setting technology on dimensional stability and elastic recovery of the two kinds of fabrics were analyzed as well. The results show that in the proper range of temperature and time, dimensional stability and elastic recovery of the nylon/spandex knitted fabric become better with the increases of temperature and time. And dimensional stability of the polyester/spandex knitted fabric also turns good. But its elastic recovery doesn't change obviously. All the measured values were compared with each other. And the results indicate that dimensional stability and dastlc recovery of these two kinds of fabrics both are great after the heat setting technology of temperature 180 ℃ and time 60 s. 相似文献

针对SAR图像中舰船目标的检测问题,单纯基于深度学习的图像处理技术难以达到检测准确性和实时性要求.SAR图像中目标尺寸较小,且易受噪声、光斑干扰,传统方法难以提取精细特征并克服复杂条件下的背景干扰.针对以上问题,设计基于YOLOv3检测框架的端到端检测模型,借鉴了残差模块结构来避免网络退化问题.同时结合深层与浅层的不同尺寸特征图检测,使用目标基础特征提取网络参数来避免重复训练初始化过程.针对SAR图像中海上舰船成像小目标的特点改进优化了神经网络结构,实现SAR海面广域舰船目标识别分类算法,并对检测模型进行轻量化压缩处理.构建SAR图像舰船目标数据集并进行了多次目标检测识别分类实验,体现了提出的检测方法在复杂场景下有可靠的抗干扰能力和准确的目标检测识别性能. 相似文献
