中文拼音 [lízishēngsù]
離子聲速
英文
ion sound eed-
Lithium niobate ( linbo3 ) has been studied and documented extensively for over three decades because of its good electro - optic coefficient and acousto - optic coefficient, its ease of processing, and its environmental stability. it is readily available commercially and is the material of choice for external modulators in long - distance high - bit - rate systems up to l0ghz
Linbo _ 3已經被廣泛的研究了三十年，由於它具有高的電光系數和聲光系數，工藝簡單，材料環境穩定等優點， linbo _ 3材料集成光子器件已經應用到實際光網路中，已經成為遠距離高速網路系統（ 10ghz以上）的外調制器優先選用的材料。By calculating parameters including the link length, the azimuth angle, the elevation, the optical power that the inter - satellite optical cdma communication system will receive, the variation range of the azimuth angle and the elevation from the optical antenna of atp are understood well. by analyzing the factors to impact bit - error - rate ( ber ) from the received power, multi - user disturbing, background noise, wavelength, bit rate etc, measures to guarantee high performances of the system are obtained, especially those for smoothing the fluctuation of the received optical power from host platform vibration
分析研究了衛星光cdma通信系統中衛星仰角、方位角和距離，給出了探測器能夠接收到的光功率以及atp子系統捕獲及跟瞄的范圍;對衛星光cdma通信系統性能模型和基於衛星振動系統性能模型的研究，分析了多用戶干擾、接收光功率、背景光噪聲、振動偏差以及碼速率對系統誤碼率的影響，給出了相應的改進措施。High efficient supersonic plasma spray technology
高效能超聲速等離子噴塗技術At the same time, the " stop - hop - stop " approximation is no longer valid in sas due to the low speed of sound. the receiver has unavoidable movement, when echoes get to receiver from different distances. in order to overcome the problem, an image forming algorithm of multi - aperture sas is presented in the thesis, which is suitable for the case of non - " stop - hop - stop "
為了解決測距、測速模糊問題， sas通常採用多子陣技術，而且由於sas 「停?走?停」假設往往不再有效，即測繪帶內不同距離回波到達基陣時，基陣存在不可忽略的運動，所以論文提出了一種「停?走?停」假設不成立條件下的多子陣合成孔徑聲納逐點成像演算法以得到相位保真度更高的復圖像。分享友人
