lobe width 中文意思是什麼
lobe width
解釋
波瓣寬度（方向圖的半功率寬度）-
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。 -
The ' shape of basal tegmen, basal piece of lateral lobe with crack in base, lateral margins of basal piece of lateral lobe, the ratio of width of lateral lobe and width of apex of basal piece, shap
本文分析討論了雌性產卵器各部分的結構特點在偽葉甲亞科分類中的意義，如肛側板是否分片、肛側板背面部分是否延長、基腹片基部大片的分節 -
In the part of window, a best window must own the following character : ( 1 ) the smallest band - width in the place of 3db, as well as main - lobe width ( 2 ) the biggest side - lobe peak - value of must be as possible as small
就窗函數而言，引入實驗的七種窗函數中，有限帶寬、三角形窗以及餘弦窗是卷積窗函數比較理想的選擇。 -
Because an antenna beam has certain width, and the antenna on the earth will point to the adjacent satellites at its side lobe, the transmitting antenna may create interfering radiation ( which is known as uplink adjacent interference ), and the receiving antenna will also be interfered ( which is known as downlink adjacent interference )
由於天線波束具有一定的寬度，地面發送天線會在指向鄰星的方向上產生干擾輻射（上行鄰星干擾） ，地面接收天線也會在鄰星方向上接收到干擾信號（下行鄰星干擾） 。
