| 摘 要： | 本文通过定义人体椎骨的中心位置，并相互连接形成椎骨中心线，来描述人体脊柱的空间三线运动。同时，引入和定义了三维考布角（CobbAngle），其可通过所建立的脊柱三维空间曲线进行计算，以此来评估人体脊柱的三维变形。

| Abstract: | In this paper, three-dimensional motion of the human spinal column is mathematically expressed by a spatial curve, which is defined and passed through each vertebral centroid. In order to evaluate three-dimensional deformity of the spine column, three-dimensional Cobb angle is introduced and defined, which can be calculated by spatial curve of the spinal column. |

| Keywords: | Spinal column Spatial curve Three-dimensional motion Cobb angle |
