In this paper, sphering method is used to revise the data depth based on spatial rank. 摘要通过球化方法得到一个改进的基于空间秩的数据深度。
The sphering 4R mechanism is the most basic and useful spheric hinge four-bar linkage which can be used to cause corresponding angle displacements of driving and driven links, and so on. 摘要球面4R机构是最基本的、最常用的球面铰链四杆机构,可用来实现主从动杆对应角位移等。
