are arecibo 中文意思是什麼
are arecibo
解釋
阿雷西博-
To make full use of the karst formation in guizhou province of china, a large spherical radio telescope array of the arecibo telescope was proposed in china in 1995. therefore, a completely new design project that integrating mechatronics and optics technologies with several large span cables is proposed to drive the feed - supporting system to realize the high precision positioning. for the high requirement of trajectory tracking of the feed - supporting system with large span cables, the feasibility of stewart platform served as a fine - tuning platform and the accomplishment of the high precision tracking are considered in details in this paper
本文依託新一代大射電望遠機電光一體化創新設計方案，針對饋源指向跟蹤系統高精度軌跡跟蹤要求，以精調stewart平臺為研究對象，進行了6自曲度並聯機器人的運動學優化設計、動力學分析與奇異性分析，設計了強魯棒性自抗擾控制器實現高精度軌跡跟蹤控制；提出了新一代大射電望遠鏡饋源指向跟蹤系統軌跡跟蹤獨立控制策略、軌跡規劃策略和控制模型； 50米縮比模型實驗驗證了軌跡跟蹤控制策略與方法的工程有效姓和可行性。 -
This is significant because of the unique geometrical features of the arecibo telescope : whereas most radio dishes are parabolic in shape, the arecibo dish is a giant half - sphere dug into the ground
這非常重要，由於阿雷西博望遠鏡的獨特幾何結構：盡管絕大多數的射電望遠碟面都是拋物面型的，而阿雷西博的碟面是在地上挖出的一個巨大半球。
