  • wave : n 〈美海軍〉女志願軍人〈見 WAVES 條〉。n 1 波浪；碎浪； 〈the wave（s）〉 〈詩〉海。2 波動；波狀...
  • summation : n. 總結；總數；【數學】加法，求和；【法律】（雙方論據的）辯論總結。adj. -al
  1. For a x - directed line current with lengh much smaller than a wave length, the e - field pattern on coordinate planes in 3 - d space in the region from much smaller than line length to one or two wave length, the synthesized pattern by summation of the field of many line segments of hertz dipoles is independent of the number of segments, i. e. same field as a single hertz dipole

    以水平面上三角形甚小於波長線電流為例，分割為若干小段之赫芝偶極所加總合成在三度空間任意座標平面上距離從甚大於線長到一兩個波長區域之電場場型與分割小段數量無關，即等同於一單一赫芝偶極之場型。
  2. Advanced mathematical technologies, especially the newly developed wavelet transform and the frame theory, provide a solid foundation for such an effort. the ray - theory based beam - summation method, such as the complex source - generated beam and the gaussian beam methods, and the local phase - space domain ( beamlet domain ) wave field extrapolation methods employing windowed fourier transform ( wft ) or wavelet transform are proposed consequently

    基於射線理論的高頻漸近射束（復射束、高斯射束）疊加方法，以窗口富里葉變換（ wft ）以及小波變換為基礎的局部相位-空間域（小波束域）波場外推方法等相繼產生。
  3. Chapter 4 : the influence of different phase - shifting angle of reference wave in recording, of the phase - shifting error and of the quantization error on the quality of the reconstructed image is investigated respectively in two - step phase - shifting inline digital holography. and an effective method of eliminating the phase - shifting error is presented, in which the summation of the intensity bit errors of the reconstructed image is taken as an evaluation function for an iterative algorithm to find the exact phase - shifting value. the feasibility of this method is demonstrated by computer simulation

    通過數值分析不同相移角的選取對再現像的強度誤差的影響，發現再現像強度誤差依賴于記錄時相移角的選取，當相移角在一定范圍內，其再現像的強度誤差相對較小；提出了一種有效消除相移誤差的新方法，並將其應用於二步同軸相移數字全息，對此進行了計算機模擬，得到了很好的結果，證明該方法對于相移誤差的消除是很有效的；對量化誤差所作的數值模擬發現，當信號被量化成8比特（ bit ） ，即256個灰度級以上，量化噪聲的影響相對較小。
  4. Based on acousto - optical coupled wave equation, the momentum mismatch is modified and acousto - electro - optical coupled - wave equations are founded. for one - dimension acousto - electro - optical effects, the momentum mismatch caused by ultrasonic wave is replaced by the summation of mismatch caused by ultrasonic wave and mismatch caused by electric field

    根據晶體中光場所遵循的麥克斯韋方程組，以及聲場與光場間的參量互作用基本方程出發，在聲光耦合波方程的基礎上，系統地建立了聲電光效應的耦合波方程理論。
