拍頻脈沖 的英文怎麼說
中文拼音 [pāibīnmàichōng]
拍頻脈沖
英文
beat pulse-
In most studies, in order to simplify the physical treatment, the laser beam is usually treated as a plane wave and normal incidence is supposed when its transmission through a fpf is considered
對于光脈沖通過法布里一拍羅濾波器后的時域和頻域特性己有不少報道,然而我們注意到,在這些研究中激光通常被當作平而波。The wakefield excited by an ultrashort and ultrahigh laser pulse propagating through tenuous plasma can accelerate electrons to extreme high energy. this can be used as a mechanism to design minitype electron accelerator. this thesis is devoted to studying those issues relevant to the wakefield accelerator, namely the laser wakefield accelerator ( lwfa ), laser wakefield accelerator driven by multiple pulses ( mp - lwfa ), plasma beat wave accel - erator ( pbwa ) and self - modulated laser wakefield accelerator ( sm - lwfa )
本文的目的是:利用粒子模擬方法,研究和比較激光尾流場加速電子的四種主要方案:短脈沖激光尾流場加速( lwfa ) 、多脈沖激光尾流場加速( mp - lwfa ) 、拍頻束尾流場加速( pbwa ) 、自調制激光尾流場加速( sm - lwfa ) 。In pulse code modulation, a spurious signal formed from beats between the signal frequency and the sample frequency
在脈沖編碼調制中,信號頻率和取樣頻率之間的差拍所引起的偽信號。
