quarter wavelength 中文意思是什麼

quarter wavelength 解釋
四方之一波長
  • quarter : n 1 四分之一。 ★3/4通常不說 three fourths 而說 three quarters 2 一刻鐘，十五分鐘；一季〈四季結賬...
  • wavelength : 【無線電】波長。
  1. The preliminary conclusion shows that the maximum rate of compression ratio changes is about 2 % and the change rate is less when the peak - to - valley value of wavefront aberration is less than a quarter of wavelength and incident angle is properly

    脈沖壓縮光柵對系統達到衍射極限時，在選擇適當的入射角度時，光柵波像差所引起的脈沖壓縮比變化並不大。
  2. Comparing to the traditional quarter wavelength monopole, the patch size can be reduced at least 50 %

    與傳統單極天線相比，貼片長度大約能夠縮減50 % 。
  3. In the case of reflection, this symmetry depends on whether a quarter wavelength fits an even or an odd number of times in the layer thickness

    而在反射的情況下，這一對稱性由薄膜厚度為1 / 4波長的奇數或偶數倍決定。
  4. The manufacturer may have guaranteed accuracy to “ one - quarter wavelength ” or as “ diffraction - limited ” but most telescope users have, at best, only a hazy idea of how to personally verifying such claims

    製造廠已保證準確性達到「一又四分之一波長」作為「有限的衍射」但是大多數天文望遠鏡用戶想擁有親自製作一種僅僅用模糊鏡的方式來驗證的方法。
  5. Through measuring the thickness of mica plates and the wavelengths at which they act as quarter wave phase retarders, the birefringence can be obtained in terms of the function relation between the phase delay, the wavelength and the thickness

    通過測量雲母材料的厚度和相應厚度情況下作為/ 4波片使用所對應的波長，利用相位延遲與波長及厚度函數關系式直接求得雲母的雙折射率。
