弹性模 meaning in English

modulus of elasticity
springform

In this paper a two - step polishing process which combined with whole aperture pre - polishing with large flexible form tools and correction polishing with small - tools is proposed to polish aspheric surface with middle aperture and replace the reiteration polishing processes
论文针对中等口径光学非球面，提出了一种结合弹性模全口径抛光和小工具修正抛光的两步研抛法，取代目前普遍使用的反复研抛过程。
Compensating different stock removal of the tool in different lens areas is used to control the accuracy in pre - polishing process . then based on preston theory , corrective polishing with small - tools is optimized and the better removal function is obtained . also a parameter related the radius of curvature is introduced and determined to increase the polishing precision , which is improved by experiments
采用反馈补偿的方法解决弹性模抛光对面形破坏的问题，以控制其抛光精度；运用preston的抛光原理，对小工具的工作方式和参数进行改进和优化，以改善其抛光精度和效率，并获得了更优的特征去除函数；提出了被抛光表面面形曲率半径对工具特征去除函数的影响，引入并确定一与非球面各处曲率半径有关的面形调整因子来降低抛光后的面形误差，并从实验上获得验证。
