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。

A bending motion equation of a tilting drive shaft with rigid multi-supports is derived by theorem of the motion of mass center, method of Galerkin and Heaviside function.

Nonlinear partial differential dynamic equations of bending vibration of a tilting stepped drive shaft with two supports were built under non-inertia movement coordinate system by theorem of the motion of mass center and Heaviside function. According to the condition of equal displacement in an adjoining plane of the shaft, an equivalent shaft and its equation were obtained. A motion equation of the equivalent shaft was obtained by method of Galerkin. An approximate steady-state solution of the main resonance was obtained by method of multiple scales. The influence factors, motion stability, amplitude jump of main resonance of a stepped drive shaft and so on were analyzed.
