lobe amplitude 中文意思是什麼
lobe amplitude
解釋
波瓣幅度-
First, it was taken that a discuss about the effects of geometry parameters of each piezocrystal on direction parameters ( main lobe width, side lobe amplitude, elimination of grating lobes ), amplitude of ultrasonic pressure, element viberation pattern, mutual radiation among elements, efficient test regions, ability to keep accurate and near - field distance and so on. based on the direction of ultrasonic field in ulpa deduced by ourselves. in addition, on the base of integrating all kinds of factors, it was put forward that the principle and method for optimized design of geometry parameters of piezocrystals in ulpa transducer, and its design programme and interface were compiled
首先在推導超聲相控線陣換能器聲場的指向性的基礎上，就各個晶片幾何參數對指向性指標（主瓣寬度、旁瓣幅度、消除柵瓣） 、聲壓幅值、陣元振動模式、陣元間互輻射、有效檢測區域、精確控制能力、近場長度等方面的影響進行了論述，並在綜合各方面影響的基礎上，提出了晶片幾何參數優化設計的原則和方法，編寫了設計程序和界面。 -
