文章首先证明了巴卜斯定理的特殊情况，然后利用此特殊情况及巴卜斯定理作了四个推广应用，最后将巴卜斯定理的原来三点共线推广到了六点共线，再推广到12n(n-1)个交点共线。

This paper firstly discusses theory and application on sensor collinearity geometry model of the satellite imagery of linear CCD push broom. The principles and technical methods of some popular math models which are used to process satellite CCD images are described and analyzed.

本文首先从线阵CCD遥感卫星影像的空间定位原理入手，研究了线阵CCD传感器基于共线方程的物理传感器模型，然后从目前常见的几种通用传感器模型入手，对仿射变换模型，有理函数模型等几何模型，进行了归纳、比较和分析。

It suggested that under static status, the nasal septum, nasal columella and the lateral feet of nasal alar were the most concentrated areas of stress distribution. They are key mechanical parts of deformed nasal.3.2 Nasal displacement load analysis of patients with unilateral cleft lip and nasal alar collapse Deformed nasal displacement load three-dimensional finite element analysis showed that if the ipsilateral and contralateral nasal parts obtain similar geometry, the positions around nasal columella in ipsilateral nostril were the most stress concentrated region, next parts were the nasal septum and the lateral nasal alar.

提示静态状态下，鼻中隔、鼻小柱和两侧鼻翼外侧角是应力分布最集中部位，也是畸形鼻部的关键力学部位。3.2单侧唇裂鼻翼塌陷畸形患者的鼻部位移载荷形变后力学分析单侧唇裂鼻畸形患者的位移载荷三维有限元分析表明，畸形鼻部的患侧要获得和健侧近似的几何形态，其患侧鼻孔近鼻小柱周围应力分布最为集中，其次为鼻中隔和患侧鼻翼外方。
