| 摘 要： | 本文简要讨论了组合不同空间技术建立全球最优协议地球参考架（ＣＴＲＦ）的理论和方法；重点分析了影响ＣＴＲＦ稳定的几种主要地球长期形变因素的性质和规律。首次考虑到地球质心运动对ＣＴＲＦ的影响，提出了协议地球质心的概念，给出了更为完整的四维地面点位模型。

| Abstract: | The theory and method of establishingglobal optimistic Conventional Terrestrial Reference Frame (CTRF) by integrating different space techniques are briefly discussed. The patterns and rules of several long-period Earth deformations wich effect on stability of the CTRF are analysed. The effect of the geocentric motion on CTRF is considered for the first time. the concept of conventional Geocenter (CG) is presented. and a more complete 4-Dimensional Model of point on the earth's surface is given. |
