A group of six international companies has announced plans to build an ultra - high speed , undersea , fiber - optic cable under the pacific ocean , between japan and the united states 六家公司宣布计划在日本和美国之间敷设横跨太平洋的超高速光导纤维海底电缆,以改善美国和亚洲地区的互联网和电讯交通。
The main topics of the summit are as the following : making methods of optical fiber and optical cable , optical communication system , optical device , integration optics , optic wave guide and electromagnetic field theory etc 交流光导纤维及光缆的制作、光通信系统、光器件、集成光学、光波导及电磁场理论等。
Dr hess envisages a ray of light travelling down an optical fibre made from two materials : a core with a negative refractive index and an outer sheath with a positive one 赫斯博士构想出一个画面,即一道光正穿越于一个由两种材料制作的光导纤维,一种是具有正折射指数的纤维核,另一种则是具有正折射指数的外围。
Dr hess envisages a ray of light travelling down an optical fibre made from two materials : a core with a negative refractive index and an outer sheath with a positive one 赫斯博士构想出一个画面,即一道光正穿越于一个由两种材料制作的光导纤维,一种是具有阴性折射指数的纤维核,另一种则是具有阳性折射指数的外围。
Special hook design could help anesthetists to solve all kinds of difficult intubation operations . by utilizing light - guide fiber device , the new - style kang antai elbowed laryngoscope is more advanced and convenient 独特的弯钩设计可协助麻醉医生解决各类疑难插管,新型的康安泰弯头喉镜运用光导纤维装置,设计更先进,使用更方便。
From the middle period of the twenties century , new industries with high technology came up . the function of technology and science stands out and the value is more and more great . more merchandise with high 20世纪中叶以来,微电子技术、光导纤维、生物工程、海洋工程、空间技术、新能源和新材料等新技术群的产生与发展,知识技术在经济发展中的作用与价值越来越突出。
Moreover , dr hess and his colleagues think it would be straightforward to attach their invention to more conventional optical devices , because at points where the core of the optical fibre is thick , it would behave quite normally 此外,赫斯博士与他的同事们认为,他们可以直接把他们的发明应用到一种更加传统的光学设施上,因为在光导纤维核心的厚处,光束能很正常的运行。
The capsule endoscope travels through the gi tract , shooting and sending out images o the traditional fiber endoscope was driven by external manipulation force , so proficient operation technique was required to prevent pains and injury of organs 传统的光导纤维胃肠道内窥镜是依靠外力进入人体的胃肠道内,不但对医生的技术水平要求很高,而且还容易划伤组织器官,给病人带来痛苦。
This area explores the scientific principles of optics and naked eye observation as related to astronomy . visitors can experiment with various optical components and look at distant objects through various telescopes . a fibre optics constellation showcase allows visitors to highlight various constellations from a control panel 可在此探索与天文观测有关的光学原理,试用不同的光学组件,并利用各种望远镜观看远处还可在光导纤维制成的星座图上,找出各个星座
It can also cure all sorts of gathering and no gathering inflammation , such as eyelid edge inflammation , seeping otitis media , central retina inflammation , gathering otitis media , chronic pharyngitis , oral ulcer , tongue pain , perleche , facial nerve palsy , bronchitis , rheumatoid arthritis , shoulder - joint - around inflammation , spot baldhead , belt sore , outside pudenda scratch and itch disease , foetus position abnormal etc . , all about 100 diseases Jh30型氦氖激光治疗仪,还可配合光导纤维输出激光,除作体表照射外,可用于腔洞组织及穴位的照射治疗。常规配置有一进一出光纤或一进二出光纤输出激光。专用与穴位照射的光纤有一进四出光纤,光纤输出端可配接穴位固定盘。
