地基大口径望远镜系统结构技术综述
地基大口径望远镜系统结构技术综述张景旭【摘要】The developing status of large aperture ground-based telescopes is reviewed in this paper.The significance of bigger apertures for telescopes and their main technological approaches are expatiated and the summary on appliance values of modern large aperture telescopes is given.Then,it introduces five kinds of modern typical large telescope systems,which represent the topmost technological level.The key structures and technologies of large telescopes about mount,telescope tubes,primary mirror supports and secondary mirror assemblies are disscussed.Finally,it summarizes the developing trends of the large aperture ground-based telescopes and points out that some of the optical systems in the telescopes have been changed from coaxial systems to off-axial systems,while they are better application prospects.%概述了地基大口径望远镜的发展状况,阐述了口径变大的意义及实现的关键技术途径。

DESCRIPTION Available either in through-hole of surface and T25 mount packages, the BTA/BTB24-25-26 triac series is suitable for general purpose AC power switching. They can be used as an ON/OFF function in applications such as static relays, heating regulation, water heaters, induction motor starting circuits...or for phase control operation in high power motor speed controllers, soft start circuits...The snubberless versions (BTA/BTB...W and T25 series) are specially recommended for use on inductive loads, thanks to their high commutation performances. By using an internal ceramic pad, the BTA series provides voltage insulated tab (rated at 2500V RMS) complying with UL standards (File ref.: E81734). ABSOLUTE MAXIMUM RATINGS
