优环境,以细致服务消除“陌生感”。近年来,一系列制度型开放举措让境外游客入境更便捷、购物更便利。但也应看到,中小商户外卡受理覆盖率不足,签证、通关、消费等跨部门流程衔接不够顺畅,“找零难”等问题依然存在。只有进一步打通堵点、补齐短板,营造“不见外”的消费环境,才能让更多境外游客愿消费、敢消费、多消费。

Implementing natural neighbour interpolation implies the construction of a geometric Voronoi diagram, however this is not strictly the case. Since the Delaunay triangulation is the dual graph of the Voronoi diagram, all the information needed to perform natural neighbour interpolation is already implicit within the triangulation itself. Algorithms to determine natural neighbours from the Delaunay triangulation can be found in several papers within the literature[4][5]. Unfortunately the relative complexity of natural neighbour interpolation means that it is slower than barycentric interpolation by a considerable margin.
