线

Various vectors have also their different linear properties, for example: position, velocity, force, electromagnetic potential etc., are 1-linear; moment of momentum, moment of force, electromagnetic intensity, etc., are 2- linear.

In this paper, we will study the definination of lines of curvature and the correlative conception, for example, normal curvature, principal direction and principal curvature and so on, the connection of lines of curvature and correlative conception, especially probe into the solution with the equation of lines of curvature and the equivalence with its determinant theorem.

本课题主要研究曲率线的定义及其相关概念如法曲率、主方向、主曲率等，曲率线与相关概念的关系，重点探讨了曲率线方程的求解及曲率线判定的等价定理。

Second: Comparetive study of ordinary X-ray film, CT and 3D-CT in the jaws fractures. Ordinary X-ray film, CT and 3D-CT was performed in 61 cases of jaws fractures. The diagnosis of these three imaging methods was compared with each other and with the operation findings. The result shows that the fractures in body and angle part of mandibal could be shown excellently by all these imaging methods. 3D- CT is the best method in showing the mandibular fractures. Ordinary X- ray film is poor, and the accuracy of CT and 3D-CT is similar in showing the macxillary fractures.

二。颌骨骨折的常规X线、CT和三维CT对比研究：通过对61例不同类型的上、下颌骨骨折常规X线、CT和三维CT显示情况的对比分析，同时与手术结果相对照，结果表明对下颌骨体部和角部的骨折三种影像学检查均显示准确；对下颌骨髁状突骨折的显示三维CT优于CT和常规X线；对上颌骨骨折的显示常规X线显示较差，CT和三维CT显示准确率相似。

The curve begins at the point where the ellipse intersects the first radial and extends counterclockwise to the point where the ellipse intersects the second radial. A radial is a line segment drawn from the center of the ellipse to a specified endpoint on the ellipse.

曲线由椭圆与第一个径向线相交的点开始逆时针延伸到椭圆与第二个径向线相交的点（径向线是指从椭圆的中心向椭圆上给定的终点之间的一段连线）。
