遠場噪聲 的英文怎麼說
中文拼音 [yuǎnchǎngzàoshēng]
遠場噪聲
英文
far-field noise-
( 5 ) the near field and radiation field of flow noise are analyzed, and the noise reducing features of riblets are deduced
（ 5 ）在分析流噪聲的近、遠場特性的基礎上，進一步研究條紋表面的降噪特性。This paper also show a rough estimate of the gains of this array, because it needs one year ' s data to collect one year ' s noise correlation variation curves and then give a more practical detection ability of the seismic array. one result of this paper is " seismic array site survery data processing software " exploited by the author. the software can calculate the power spectrum of noise for every site, noise coherence function for every site pair, the cross - correlation curves, the root mean square of noise for every site and the array response
此外還計算了該臺陣的臺陣響應，發現臺陣響應的主瓣高而尖；旁瓣很小，這歪姐鈕遠宣腔撾踏數公鍍壁韶逼上攏唆精確啻應：有關此臺陣的檢測能力，只能給出一個粗略的估計，因為評價一個臺陣對地震事件的檢測能力需要獲得為期一年的觀測資料，才能給出一年內噪聲場變化的相關值曲線，最終給出更加符合實際的臺陣檢測能力。Because the element of the far field diagnosis system which is used to detecte facula is ccd, when it works, much types of noise will affect it, and threshold value will affect the efficient signal. in this paper, hartmann - shack wavefront sensor which can detect the phase of beam is studied, what is detected by hartmann - shack wavefront sensor can be transform into far field, and we compare this result with that detected by the far field diagnosis system, and we can know which system is more accurate
事實上， hartmann - shack波前傳感器的ccd在探測光斑陣列時，也同樣受ccd噪聲因素的影響，並且還有波前本身的復原誤差，但是hartamnn - shack波前傳感器的ccd噪聲影響的是波前復原精度，雖然這也將導致事後處理遠場光斑的誤差，但這種誤差與遠場測量系統的誤差相比孰大孰小是本文研究的主要內容。
