分量 分量weight 給足分量 give full measure; 分量給得不足 give short measure; 他這話說得很有分量。 what he said should not be taken lightly.; what he has said carries a lot of weight. 這本書的分量可不輕。 this book is quite heavy. 我相信她的話在校長(zhǎng)面前有一些分量, 她有可能說服他。 i believe she has some influence with the headmaster -- she might persuade him.
Results show that the parallel transmission intensity approximately shows an exponentially decline distribution while the vertical one displays a rising - then - declining trend 利用實(shí)驗(yàn)數(shù)據(jù),分析了垂直、平行方向上透射光強(qiáng)的變化趨勢(shì),得出平行偏振分量透射光強(qiáng)大致呈指數(shù)下降的趨勢(shì),垂直偏振分量透射光強(qiáng)先略微上升而后下降。
Under certain conditions , in spite of their different modal indices the two polarized components of the pulse can trap one anther and move at a common group velocity due to xpm , the phenomenon referred as self - trapping occur 在一定條件下,盡管脈沖的兩個(gè)偏振分量的模式折射率不同,但由于交叉相位調(diào)制效應(yīng),它們能相互俘獲并以共同的群速度傳輸,產(chǎn)生自捕獲現(xiàn)象。
3 ) coupled higher - order nonlinear schr ( ? ) dinger equations ( chnlse ) , governing the evolution of two orthogonal polarization components of ultrashort optical pulse in birefringent fiber , are derived from the dispersion relation 3 )從色散關(guān)系出發(fā),推導(dǎo)了描述超短光脈沖不同偏振分量在雙折射光纖中傳輸特性的耦合高階非線性薛定諤方程( chnlse )與用多重尺度法得到的相同。
In the section 1 , we have introduced the background and the recent advance of the flattened gaussian beam ; in the section 2 , for the first time , we have calculated the type - i and type - ii shg conversion efficiency and simulated curves versus the crystal length , the pumping light polarization rate , the order of the flattened gaussian beam and the pumped power intensity , we obtain ed that the highest efficiency was influenced by the order and the polarization rate of the pumped flattened gaussian beam 從三波耦合方程及clbo晶體的光學(xué)特性出發(fā),討論了以平頂高斯光束入射時(shí)穩(wěn)態(tài)的三波耦合方程的大信號(hào)倍頻解(包括類及類相位匹配的倍頻解) 。計(jì)算了其在clbo晶體上的倍頻轉(zhuǎn)換效率與晶體長(zhǎng)度,基波偏振分量比,基波階數(shù)及泵浦波強(qiáng)度之間的相互影響關(guān)系曲線。得出影響平頂高斯光束的最高轉(zhuǎn)換效率的因素是基波的階數(shù)n和泵浦波的偏振分量比d 。
4 ) in addition , a class of optical solitary wave solutions , such as the bright - bright , dark - dark , bright - dark , and combined solitary waves , especially the interesting w - shaped solitary wave solutions for chnls equations are found under certain parametric conditions . the properties of these optical solitary solutions are presented . furthermore , we investigate the stability of theses solitary waves under some initial perturbations by employing numerical simulation methods 4 )在一定參數(shù)下得到了描述超短光脈沖不同偏振分量在雙折射光纖中傳輸特性的耦合高階非線性薛定諤方程( chnlse )的亮亮、暗暗、亮暗、組合孤波解析解,包括一種非常特殊的“ w ”型孤波解,對(duì)這些孤波解的特性進(jìn)行了分析,也討論了它們的穩(wěn)定性。
2 ) based on the maxwell equations of nonlinear media , high - order coupled equations governing the evolution of two orthogonal polarization components of the same wave are derived by using multi - dimension derivation expansion method of singular perturbation theory , and the suitable application range is presented 2 )利用奇異攝動(dòng)多重尺度導(dǎo)數(shù)展開法,從非線性介質(zhì)中的maxwell方程組出發(fā),導(dǎo)出了包含高階攝動(dòng)項(xiàng)的同一光波不同偏振分量的耦合高階非線性薛定諤方程,并給出了其適用范圍。
