As the necessary components for various modern electronic and optoelectronic devices, novel transparent electrodes(TEs) with the low cost, abundance features, and comparable performance of indium tin oxide(ITO) are inquired materials. Metal nanowires(NWs) with the excellent photoelectric properties as next-generation TE candidates have widely applications in smart optoelectronic devices such as electronic skins, wearable electronics, robotic skins, flexible and stretchable displays. This review describes the synthetic strategies for the preparation of metal NWs, the assemble process for metal NW films,and the practical aspects of metal NW films with the desired properties in various low-cost, flexible,and solution-based photoelectric devices.

Waterfront resources are important and special kind of natural resources in the marginal area between land and wat er. The Yangtze River, the longest river in China, is not only rich in waterfront resources, but also has favorable development conditions with gr eat potentiality. Aided by large-scale underwater topographic map, the maj or factors of the waterfront resources in the middle and lower reache s of the Yangtze River, such as the stability, the water depth and the natural conditions for port construction, are assessed in this pap er respectively on the basis of the overall investigations. The result s show that: (1) the waterfront resources are abundant in the middle and lower reaches of the Yangtze River, but lack of perfectly combined high grade waterfront; (2) there exists an obvious regional difference in the natural quality of the waterfront along the Yangtze; (3) the fore-bank water depth and waterfront stability are the main natural fa ctors related to the waterfront quality in the middle and lower reach es of the Yangtze River; (4) the waterfronts along the Yangtze are mainl y used for port, warehouse and industrial purposes; and (5) the waterfronts near important cities are highly used, especially the high-quality waterfronts. In addition, some suggestions for the development and utilization of the waterfron t resources are presented in this paper.

塔里木盆地塔中地区奥陶纪石灰岩地层与泥岩地层界面有两种特殊的地质现象:1泥岩沉积期局部发育石灰岩,与下伏石灰岩沉积形成假连续沉积;2石灰岩顶不整合面发育岩溶储层,储层波阻抗与上覆泥岩地层相近。因此在地震记录上可能会出现"穿时"的地震响应特征而掩盖真实的储层信息和地层信息。为此,提出了基于厚度约束的匹配追踪算法,以挖掘出更多、更准确的地震信息去表征所要关注的地质体。首先将原始地震数据分解成不同频率的多个原子;然后以地质目标体厚度所对应的频率作为约束阈值,剔除分辨率低于地质目标体的低频原子,从剩余原子中筛选出最能体现地质目标体的原子来做地震重构;最后利用重构地震数据完成储层预测和石灰岩地层分布预测。该方法在R井区的实际应用中,重构的地震剖面还原了"串珠"顶部的真实位置,结合地震反演后成功识别出泥岩底部局部沉积的石灰岩地层,为地震解释方案的制定和探井深度设计提供了参考依据。

目前,对于大小、形状各异的物体,机器人多指手的抓取规划和控制问题尚未得到完善的解决。总结现有各类机器人手掌,发现一些新型手掌结构可以提高机器人多指手的灵巧性和工作空间,且结构和控制相对简单。基于此,分析了章鱼腕的运动机理,提出了广义腕掌结构,可构型出任意大小和形状的多边形,并依此结构设计了一种12自由度的仿生机器人四指手。为了简化结构和控制,设计了一种5自由度的新型手掌结构,命名为可变腕掌。对于不同大小和形状的物体,可变腕掌能够自适应改变手掌构型,将手指变位到最佳的接触点位置,大幅提高了机器人多指手的灵巧度和工作空间。构型分析表明,对于大小、形状各异的物体,可变腕掌能够简单快速地实现自适应构型,既提高了机器人多指手的抓取质量,又降低了抓取规划和控制的难度。
