This paper describes a radial tilt detection method that is based on analysis of the intensity distribution of reflected light from the optical disk. This method can be performed with high accuracy even at the boundary area of recorded and unrecorded tracks, and with an objective lens displacement. Furthermore, a tracking error signal detection method that can be used with the tilt detection method simultaneously is described. Its performance was confirmed experimentally using the optical pickup for a Blu-ray Disc.

我最亲爱的别人家的小孩: 你好! 或许你正在奇怪为什么我会写这封信给你,因为你与我不曾说过一句话,并不相识,更不是朋友。但其实你不知道,你和我在同一个村庄长大,就读于同一所小学、初中、高中。对你来说,我只是一个陌生的别人家的小孩。但在我心中,你是我最亲爱的别人家的小孩。 从小就被所有人称赞懂事的我,也是老师眼中的好学生。直到你的出现。相隔不远的你,大我两岁,品学兼优,聪明活泼,一下子抢走了所

钢-混凝土组合梁中,由于栓钉连接件产生剪切变形,导致混凝土板和钢梁的变形不协调,从而产生相对滑移,影响组合梁的抗弯承载力.国内外许多专家对此进行了研究,得到了一系列的研究成果.本文首先对国内外的研究进展进行概述,叙述了各类组合梁考虑滑移效应的抗弯承载力计算方法.然后通过实例计算,对滑移效应的影响进行定量分析,并与试验结果进行了对比,验证了滑移效应会对弹性抗弯承载力产生较大影响,并证明在极限抗弯承载
