2018年安溪珠塔内窑调查报告

2018年5月至7月,厦门大学历史系考古专业、福建博物院文物考古研究所及安溪县博物馆等单位联合组成\"安溪古窑址调查队\",对安溪珠塔内窑进行了全面的调查,基本了解珠塔内窑古窑址分布与保存情况,采集了一批明末清初的青花瓷器、白瓷与窑具标本,并发现部分窑炉遗迹,为研究闽南地区青花瓷窑业发展提供了第一手资料

Design and experimental study of space continuous robots applied to space non-cooperative target capture

Space capture actuators face problems such as insufficient flexibility and electrical components that are vulnerable to extreme space environments. To address these problems, a centralized-driven flexible continuous robot based on a multiple scissor mechanism units is proposed in this study. The continuous robot body is composed of two scissor mechanism units coupled in series, and the base container&rsquo;s three motors to drive the robot. The two scissor mechanism units ensure a wide range of flexible operations and the light weight of the robot. The centralized drive with three motors not only reduces the number of driving sources, but also ensures temperature control and protection of electrical components in the space environment. The kinematics and dynamics of the robot are analyzed, and the workspace and deformation performance of the robot are verified through experiments. Compared with other continuous robots, the proposed continuous robot retains the characteristics of continuous robots in a wide range of flexible operations. At the same time, the configuration is light and a small number of driving sources are used, which is suitable for extreme temperatures, vacuum, radiation, and strict resource-constrained environments in space.</p
