| 摘 要： | 讨论了构造块体在球面上运动的两种运动学模型。其一称之为“完全模型”，把构造块体视为刚体，把地球近似为圆球，则块体在地表的运动可用该模型完全描述。其二称之为“平移模型”，当构造块体上的观测点不足时，通过增加约束条件，可用该模型描述块体间的相对运动。阐述了两种模型的适用范围以及确定运动参数的方法，导出了计算公式，并给出了两个算例。

| Abstract: | Two kinematic models of tectonic block motion on the earth surface are discussed. One is called the perfect model, by which the tectonic block motion on the earth surface could be described if regarding the tectonic block as a rigid body and approximating the earth to a ball. Another is called the translational moder, by which the relative motion among the blocks could be described if the constraint condition is added in case of lack of observational points on the tectonic block. The applicable scopes of two models and methods of determing the kinematic parameters are indicated. Finally the computation formula are inquired and two examples are given. |
