本文考察了两种"有"字句的指称特性,在住所词做主语的"有"字句中"有"字宾语趋向于虚指,为典型的存现句;在无主语"有"字句中"有"字宾语趋向于实指,说明"有"字兼有实指标志... 本文考察了两种"有"字句的指称特性,在住所词做主语的"有"字句中"有"字宾语趋向于虚指,为典型的存现句;在无主语"有"字句中"有"字宾语趋向于实指,说明"有"字兼有实指标志的功能。这种"有"字虽然有存在意义但句式不是典型的存现句。 展开更多

For the virtual environment (VE) to control remote robots through Internet, this paper proposes an operational idea based on virtual guides (VGs). The VGs consist of three types, line VG, plane VG, and body VG, which can greatly enhance the safety and flexibility of the man-machine system. Through the analysis of several common cases, the idea of the VGs are first introduced and described. Second, detailed descriptions of the three VGs are given, and then a uniform representation of all VGs is given. Finally, a typical experiment is designed and implemented according to the modes of video feedback, video&VE feedback, and video&VE&VG feedback. Experimental results show that the operation based on VEs and VGs have significant advantages over that based on video feedback, and VGs can greatly improve the ability of the VE to control remote robots, thus obtaining high and efficient man-machine cooperation. 展开更多
