中文拼音 [qīngxiétiānxiàn]
傾斜天線
英文
tilted antenna-
Scanning in declination may be achieved by tilting the aerial system.
進行赤緯掃描時，可以把天線傾斜。A heavy surf thundered and burst over an outjutting rock ; lowering storm - clouds covered the sky ; and, outside the line of surf, a pilot - schooner, close - hauled, heeled over till every detail of her deck was visible, was surging along against a stormy sunset sky
怒濤澎湃，拍擊著一片橫空斜出的峭壁；孕育著風暴的黑雲低垂，布滿天空；浪濤線外一艘領港船正乘風前進，船身傾斜，甲板上的一切都清晰可辨。Through analysis of potential vorticity in isobaric surface field, in low - troposphere a positive potential vorticity disturbance exist and form incline disturbance column northward before rainstorm generation, at the same time have also reflected positive potential vorticity disturbance for severe convection weather trigger role in lower - troposphere ; soon positive potential vorticity disturbance in high - troposphere downward, form one vertical disturbance column, now corresponding precipitation develop stage ; in the prosperous stage of rainstorm that maintains isolines of horizontal distribution and still have straight positive potential vorticity disturbance in 600 - 700 hpa isobaric surface field ; when near ground arises negative potential vorticity disturbance, precipitation also weaken
通過對等壓面的位渦分析，發現了在暴雨發生前，在對流層低層有正位渦擾動存在並向北形成傾斜的擾動柱，同時也反映了對流層低層正位渦擾動對強對流天氣的觸發作用；隨后高層正位渦向下擾動，形成一個垂直擾動柱，這時對應降水的發展階段：在暴雨的鼎盛階段， 600 700hpa上空維持水平分佈的等值線，在其上還有正的位渦擾動；當近地面出現負的位渦擾動時，降水隨之也減弱。By contrast with some foreign countries, such as usa, uk and so on, those countries had carried out new iso standard for a period of time, so they have developed special implements to measure those five errors, like 6d / lms created in usa. those implements have greatly improved the testing efficiency of machining center ' s geometric accuracy
而國外美英等國先於我國執行iso的新標準，他們已經研製了直線度誤差綜合檢測儀，如美國的api公司研製的6d lms激光干涉儀可同時檢測除傾斜一項的其他四項誤差，使檢測時間從2 ? 3天減為半天，極大地提高了生產效率。This article introduces some aspects of development of the tilt sensor at home and abroad as well as the principle of measurement, the application in carrier antenna controller is included
本文簡要介紹了國內外傾斜傳感器的發展情況和測試原理，以及在艦載天線控制中的應用。The serpentine feed is the core of a frequency scanning antenna feed system, which produce proper amplitude and phase distribution for the antenna arrays. most of all, it make the beam scanning over a large angle range by means of changing operating frequency
它為天線陣提供要求的幅度、相位分佈，更為重要的是當頻率發生少許變化時使線源的等相位面產生顯著的傾斜，完成波束在空間掃描。Antenna tilt indicator
天線傾斜指示器The results of computer simulation a re proved. thirdly, the paper analyze the angle error caused by elevation axis not in horizontal plane, make a conclusion that 3 - axes perpendicular radar can not track in the whole airspace, propose the structure of slant 3 - axes radar
然後，從工程實際出發，著重分析了俯仰軸不嚴格水平對雷達測角系統造成的誤差，得到了正交三軸雷達並不能進行全空域跟蹤的結論，提出了傾斜三軸的雷達天線座結構形式。Antenna tilt error
