Transmission character of pulse - shaped noise in insulation monitoring for turbo - generators 汽輪發(fā)電機(jī)絕緣監(jiān)測(cè)中脈沖型噪聲的傳播特性
We studied the effects of pulse - shape , an additional static electric field and different initial states on ionization probability and hhg . we did so by representing the results of a series of numerical experiments on a one - dimensional model hydrogen atom 本文將采用數(shù)值計(jì)算法來(lái)求解含時(shí)schrodinger方程,研究在一維氫原子模型中,外加的平行靜電場(chǎng),不同形狀的激光脈沖以及原子處于不同初始態(tài)對(duì)諧波譜線和電離率的影響。
The semiclassical interpretation describes three processes of hhg very visually , but it does n ' t give the details . lewenstein theory explains the position of cut - off by using a quantized method . in chapter three the pulse - shape effects of laser - atom interaction system are discussed 在第三章中,我們討論了激光-原子相互作用體系的脈沖形狀效應(yīng),發(fā)現(xiàn)氫原子的電離率大小和高次諧波特征都與所加的激光脈山東師范大學(xué)碩士學(xué)位論文摘要一沖形狀有密切關(guān)系。
The series of results showed that there is a close relationship between the ionization probability and the pulse - shape , which in turn affects the hhg . when the pulse is turned on very slowly or rapidly the character of hhg wo n ' t be obvious . only if the turn - on is proper the spectrum of hhg will be ideal 當(dāng)激光脈沖的時(shí)間長(zhǎng)度不變時(shí),脈沖開(kāi)啟的快慢會(huì)影響到電離率和高次諧波,開(kāi)啟很慢或很快時(shí),諧波的平臺(tái)結(jié)構(gòu)都不明顯;只有在適當(dāng)?shù)拈_(kāi)啟下,電離率處于中間值,這時(shí)高次諧波譜線才比較理想。
