Frege, Russell, Kripke, etc., analyzed and explained this problem, and their views are not the same: Frege did not make the distinction between proper names and descriptions, and thought that difference in other aspects between proper names and descriptions can be tolerated as long as their references are the same; yet Russell strictly distinguished proper names from descriptions; and Kripke regarded proper names as rigid designators, and descriptions as non-rigid designators.

弗雷格、罗素和克里普克等人都对名称问题进行了分析和说明，而且他们的观点都不尽相同：弗雷格不区分专名和摹状词，认为它们只要指称相同，其他方面的不同都是可以容忍的；罗素严格区分了专名和摹状词；而克里普克却认为专名是严格的指示词，摹状词是非严格的指示词。

Plates of globular cluster M3, taken with the 40cm refractor at Sheshan station of Shanghai Astronomical Observatory, are used by this work. The difference of epoch of these plates is up to 81years. The positions and absolute proper motions of 24 stars in ACT catalogue, which links with the Hipparcos Catalogue based on the International Celestial Reference System, are used as the reference frame. Using the central overlapping principle, the absolute proper motions of 534 stars in the region of about 100'×100' around the cluster are determined. After the membership determination of the stars which based on the data of proper motions, average absolute proper motion components for the cluster of -0.3±0.3 mas/yr in R.A.

本文使用上海天文台佘山40厘米折射望远镜拍摄的14张最长时间跨度为81年的球状星团M3底片的PDS扫描结果，使用与 Hipparcos星表相联系的基于国际大球惯性参考系的ACT星表中的 24颗恒星的位置和绝对自行为参考架，用中心重叠法进行天体测量归算，得到了这个星团中心附近100'×100'天区内534颗恒星的位置和绝对自行，并利用这些自行对成员概率进行了估算，得到这个星团的赤经方向绝对自行为- 0.3±0.3mas/yr，赤纬方向绝对自行为-3.1±0.3mas／yr。
