發球方法包括，反手上旋球和下旋球，正手上旋球和下旋球。和高拋發球。Because of the demand of aspherical lenses, itrc combines optical, mechanical and electrical technology to develop an aspherics polishing system using negative - shape polishing method
在非球面光學鏡片需求增加的今日，儀科中心集成光、機、電技術，發展出應用負形拋光法之非球面拋光系統。Then according to the mrf machine ’ s structure and motion mode, the function and assignment of mrf machine cnc system are analyzed. the design and implementation of cnc system are researched, and a set of pc - based open architecture cnc system is developed. a trace interpolated algorithm of mrf machine cnc system is advanced according to the characteristic of mrf. the symmetry axis curve surface, such as aspheric surface, which is fit for optics general equation can be machined with mrf machine by using this interpolated algorithm
然後根據磁流變拋光機床的結構和運動方式，從工程實際應用出發，分析了磁流變拋光機床數控系統的功能和任務，研製了一套基於pc的具有開放式體系結構的數控系統，同時針對磁流變拋光的特點，提出了磁流變拋光數控系統的軌跡控制插補演算法，運用該演算法可對非球面等適用於光學通用方程表示的回轉對稱曲面進行磁流變拋光加工。The discovery of these laws is only possible when we entirely give up looking for a cause in the will of one man, just as the discovery of the laws of the motions of the planets has only become possible since men have given up the conception of the earth being stationary
只有當我們完全拋棄在一個人的意志中去尋找原因的時候，才能發現這些法則與此相同的是，只有當人們拋掉那些有關地球的一切成見，才能揭示行星運動的法則。分享友人
