To solve the problem of quadric surface reconstruction in reverse modeling for mechanical parts, a two-step fitting algorithm was presented. 摘要針對(duì)機(jī)械零件反求建模過(guò)程中常見(jiàn)二次曲面的表面重建問(wèn)題，提出了曲面擬合分步計(jì)算法。

Lastly, experiments were performed to evaluate the performance of this method in comparison with the methods using linear classifier and quadric surface. 最后，為了評(píng)估該方法的性能，分別使用線性分割器和二次曲面分割器的方法進(jìn)行了對(duì)比實(shí)驗(yàn)。

In this paper, the authors expounded covariance analysis with two correlated variables and solved it with quadric form. 利用二次型解決了雙協(xié)變量的方差分析方法。
