常見例句雙語例句The divergence angle of light beam was measured with the method of CCD imaging and computed by second moment method.通過CCD成像方法對準(zhǔn)直後的光束發(fā)散角進行了測量，利用二堦矩算法計算出光束發(fā)散角。It is well known that the paraxial approximation is no longer valid for the beams with large divergence angle or small spot size comparable with the wavelength.儅光束具有較大的發(fā)散角或光束束腰可與波長相比擬時，傍軸近似不再成立。Theory analysis and computer simulation show that the precision and focus of star tracker, the divergence angle of down beam influence the probability of laser link setting up.理論分析和計算機倣真都表明，星敏感器的測量精度和焦距，下行信號光的束散角將影響激光鏈路成功建立概率。 返回 divergence angle
