譜線亮度 的英文怎麼說
中文拼音 [pǔxiànliàngdù]
譜線亮度
英文
spectral luminance-
The spectrum of a galaxy contains bright and dark lines that are determined by the galaxy ' s temperature, density, and chemical composition
一個星系的光譜中包含亮與暗的線，這是由星系的溫度、密度和化學成分決定的。Owing to lack of auotmatic separation of led in our country, we borrow ideas from other countries and design a suit of equipment of automatic dection and separation of led. the equipment consists of several parts : led transportation setup ( disc libration setup, line libration setup ), equidistant receving setup, detecting system and automatic separation of led. the equipment achieve automatic separation of led and pipelining. the research lay stress on machanical structural design and order action control which achieve automation separation by using pc and plc
可完成led波長和亮度的在線檢測、自動處理和自動分選，實現了led在線分譜檢測與自動分選的流水線作業。自動分選的機械結構設計、動作實現設計和順序動作控制是本論文的重點。自動分選的實現是通過pc與plc的結合完成對plc的順序控制。By use of g. d. shen ' s tunneling cascade theory we have fabricated high performance and high power tunneling cascade ingaas / gaas / algaas 950nm / 990nm double wavelength strained quantum well lasers on the basis of former tunneling cascade high power lasers and high brightness light emitting diodes. the lasers " two peak wavelength are 95 ? nm and 990 ? nm. el spectrum ' s fwhm is 3nm
在以往隧道級聯大功率應變量子阱激光器及高亮度發光管的理論研究與實驗的基礎之上，採用沈光地教授提出的隧道級聯思想，成功研製出基於ingaas gaas algaas材料的高性能大功率隧道級聯950nm及990nm雙波長應變量子阱激光器，激射波長分別為952 2nm和990 2nm ， el譜的譜線寬度約3nm ，未鍍膜器件單面最大輸出光功率可達2w以上，閾值電流最低達120ma 。1 measurement items : luminance ( transmittance, grey scale inversion ), chromaticity, response time, flicker, eoc, gamma curve, view angle performance, spectrum, reflective luminance, reflective chromaticity, reflectivity, module optical performance with certain temperature range
