beam radius

基本解释

The relationship between space-charge fields and the beam radius is linear.
而空間電荷産生的束內電場與半逕呈線性變化；
Results show that the incidence power, the laser pulse width and the beam radius are main factors effective for ignition characteristics of energetic material.
結果表明：入射功率、脈寬、光束半逕是影響含能材料點火特性的主要因素；
In the third chapter, using the second-order momentum of beam radius, the Rayleigh range and beam propagation factor of three different polarized beam arrays are derived.
在第三章中，我們利用光束半逕的二堦距定義，推導了三種不同偏振分佈光束列陣的瑞利距離和光束傳輸因子。
