Based on the previous research on the portal crane administration, one standpoint put forward in this paper is idea that is on the foundation of reliability in this paper, two viewpoints take shape when reason is analyzed, that is fatigue break and appearing the flaw that will extend. What is the fatigue break?(this phenomenon is always happen in some place),the fatigue is that board appears apophysis and concave when the board is pressed .so that the board ability of bearing the weight of load will descend. Second , the board appear the flaw that the flaw extends in the some place of board one reason is that the machine works too long, so the board ability of bearing the weight of load will decline.

本论文建立在已有的港口装卸机械管理的研究基础之上，进一步提出了以可靠性为基础的港口装卸机械的管理思想，已有的研究表明，港口机械设备破坏主要由于两个原因，第一是稳定性问题，特别是构件的局部稳定性，所谓稳定性是指：在板的平面内，板受到平行于板面的压力作用，使板发生隆起、内陷等凹凸不平的结果，从而使板受载能力减弱；第二是结构出现疲劳裂纹及其扩展，这是由于设备长时期运行，而造成设备某些部位出现裂纹并得以扩展，使设备承载能力下降。

This article outlines the progress of ancient Chinese lenses from the Pre-Qin Period to the Five Dynasties, and discusses mainly two arguments: First, the"yangsui" recorded and narrated in Lun Heng by Wang Chong of Eastern Han Dynasty may be a plano-convex glass lens; secondly, the"four mirrors" recorded and narrated in Tanzi Hua Shu by Tan Qiao of Southern Tang Dynasty may be a plano-convex lens, a biconvex lens, a transparent planeparallel plate and a concave-convex lens respectively, but what kind of tra...

本文概述了中国古代透镜从先秦到五代的发展进程，着重从古代文献和出土文物的研究出发，结合中国古代社会经济发展水平，论证了东汉王充《论衡》中记述的阳燧可能是玻璃平凸透镜；论证了南唐谭峭的《谭子化书》中记述的"四镜"可能是平凸透镜、双凸透镜、平光镜和凹凸透镜。作者认为《谭子化书》"四镜"段可能实际上是对中国古代透镜发展的阶段性总结。
