As an example , we studied the co - propagation of two soliton beams with one ' s amplitude is much stronger than another . it is then found that the weaker ( probe beam ) can experience a very large phase shift within a rather short propagation distance by modulating the input power of the stronger ( pump beam ) . chapter 3 , nnlse is simulated for two beams propagation 以振幅一強(qiáng)一弱共同傳輸?shù)墓伦庸馐鵀槔M(jìn)行了具體研究,相位分析顯示,與局域孤子相比,孤子光束在相當(dāng)短的傳輸距離之內(nèi)能產(chǎn)生大的相移,可以通過對(duì)強(qiáng)光(泵浦光)能量的調(diào)控來實(shí)現(xiàn)對(duì)弱光(信號(hào)光)的相位調(diào)制。
A new measurement system for electrical conductivity in an yj - 3000t press fitted with a wedge - type cubic anvil was set up on the basis of the old one . a solartron 1260 impedance / gain phase analyzer was used in the new system ; mo electrodes and a mo shield were also used to keep oxygen fugacity close to the mo - moo2 , which is similar to that of iron - wustite ( iw ) 在yj ?緊裝式六面頂壓機(jī)上,對(duì)原有的礦物、巖石電性測(cè)量系統(tǒng)進(jìn)行了進(jìn)一步的改進(jìn):建立了一套以solartron1260阻抗增益?相位分析儀為測(cè)試儀器,使用mo電極和mo盾來控制樣品氧逸度的測(cè)量系統(tǒng),該系統(tǒng)的氧逸度環(huán)境為mo ? moo _ 2 ,接近iw緩沖對(duì)。
2 - d fourier technique could compute horizontal and vertical speed of cloud motion in the same time , so it can avoid the error caused by 1 - d moving supposition in the 1 - d fourier technique . in this part , the 2 - d fourier technique theory was introduced , and a numerical simulation was given in this paper . in the third part , we compared the 2 - d fourier technique with the 1 - d fourier technique , analyzed their problems and found ways to resolve them 用二維傅立葉相位分析法導(dǎo)風(fēng),同時(shí)計(jì)算水平和垂直方向的風(fēng)速,能夠避免一維傅立葉相位法導(dǎo)風(fēng)中一維平移假設(shè)帶來的誤差,文中介紹了二維傅立葉相位法導(dǎo)風(fēng)的基本理論和風(fēng)速計(jì)算方法,并給出二維傅立葉導(dǎo)風(fēng)技術(shù)的數(shù)值實(shí)驗(yàn)。
