1. For making the new technique of tension strength testing method have the good and practical value, and avoid causing the large discreteness in the application. 为了使抗拉强度检测新技术具有良好的实用价值，避免在应用中有较大的离散性、此利用这种检测方法的结果，有必要讨论在给定可靠度的置信区间。
2. So the polynomial interpolation applied to light spot image is presented, which can improve the detecting precision of spot by reducing the discreteness of image and noise. 文章提出用多项式插值对光斑图进行插值处理来降低图像灰度的离散度，可以平滑光斑图噪声，提高光斑阵列的探测精度，从而提高波前探测精度。
3. Deep reading and shallow reading are different in reading contents, purposes, actions and psychology. Deep reading is not the antithesis of shallow reading, but discreteness. 而深阅读需宁静、专注，是以获取知识为主的阅读形式深浅阅读在阅读内容、目的、动作和心理上存在差异。
