本文介绍了反求工程的应用领域，讨论了坐标点的测量技术及各种测量方法的特点与适用范围，阐述了反求工程中曲面重建技术，分析了曲面重建中存在的主要问题，提出了离散"点云"的预处理算法及利用CAD造型软件进行曲面造型的方法，并开发了"点云"数据优化处理程序。

Because the projection matrix errors have been considered in the total-least square algorithm, this method is helpful for obtaining a better solution under this circumstance.

由于这种重建方法在其推导过程中已经考虑到投影矩阵中存在误差这一事实，因此，这种方法对于减小投影矩阵误差对重建结果的影响无疑是有益的。

The two bundle need to be reconstructed in order to restore the function of anterior cruciate ligament.lt is coincident to the propery of kinematics that the knee be fixed at the 110 degree in the early stage.

结论膝关节屈伸过程中前内侧束和后外侧束的是两束不同的功能单位，要恢复前交叉韧带的功能应当将两束分别重建。在重建后早期将韧带固定于屈膝110度的位置更符合运动学的特性。州陪怂岁

Methods Eighteen patients with biliary calculi underwent volume scanning using spiral CT (Hispeed Advantage CT/i GE ). All data were transferred to computer workstation, and CT biliary virtual endoscopy images with pseudocolor encoding were generated from the volumatric data using the Navigator Smooth soft-ware.
