例句與用法

For the negative uniaxial crystal material , the principal mode is a hybrid guided mode , which can also be excited by the light at any frequency , but when the single mode propagation condition can not be satisfied , some of the higher order hybrid guided modes will exist in the waveguide
對(duì)于負(fù)單軸晶體，波導(dǎo)的主模是混合模hgm _ 0模，該模式同樣可被任何頻率的光波所激勵(lì)；當(dāng)光波波長(zhǎng)滿足一定條件時(shí)，波導(dǎo)內(nèi)傳輸單模，否則，將激勵(lì)起高階混合模。
The most achievement is that we firstly obtain the analytic accurate solution of the modal fields of the waveguide structure and find some available character : ( 1 ) the different uniaxial crystal materials have the different propagation properties ; ( 2 ) when the optical axis of the crystal is on the plane that is made up of the normal direction of the waveguide plane and the propagation , there are te mode and tm mode in this special waveguide , but the principal mode is different of the character of the uniaxial crystal , the principal mode is the principal mode of te mode for the negative uniaxial crystal , but the one of tm mode for the positive uniaxial crystal ; ( 3 ) when the crystal optical - axis parallel to the waveguide plane , for the positive uniaxial crystal material , the principal mode of the waveguide is a te wave , which can be excited by the light at any frequency ; when the light frequency satisfies a single mode propagation condition , there will be only the principal mode propagating in the waveguide , otherwise some of the higher order modes can be excited , which are neither te modes , nor tm modes , but the hybrid guided modes
本文就是在此背景下，利用金屬波導(dǎo)和單軸晶體的一些特性，結(jié)合麥克斯韋方程組和波導(dǎo)的邊界條件，從三種不同的情況研究了光在對(duì)稱平面單軸晶體金屬波導(dǎo)(波導(dǎo)層是單軸晶體，兩個(gè)波導(dǎo)界面均為金屬)內(nèi)的傳輸特性，其主要貢獻(xiàn)為，首次解析地得到了這種波導(dǎo)結(jié)構(gòu)下模式場(chǎng)的精確解，并發(fā)現(xiàn)了一些有用的特性： ( 1 )模式場(chǎng)的性質(zhì)因單軸晶體的性質(zhì)不同而異； ( 2 )當(dāng)單軸晶體光軸位于波導(dǎo)界面法方向與傳輸方向構(gòu)成的平面內(nèi)時(shí)，波導(dǎo)中傳輸te波和tm波，只不過其主模因單軸晶體的性質(zhì)不同而異，當(dāng)波導(dǎo)層介質(zhì)為負(fù)單軸晶體時(shí)，波導(dǎo)主模是te波主模，而波導(dǎo)層介質(zhì)為正單軸晶體時(shí)波導(dǎo)主模是tm波主模。 ( 3 )當(dāng)單軸晶體光軸位于波導(dǎo)面內(nèi)時(shí)，對(duì)于正單軸晶體，波導(dǎo)的主模是橫電波te _ 0模，任何頻率的光波均可激勵(lì)該模式；當(dāng)光波波長(zhǎng)滿足一定條件時(shí)，波導(dǎo)內(nèi)傳輸單模，否則，將激勵(lì)起高階模式，高階模即匪te波，也匪tm波，而是兩者耦合而成的混合模。
Simulation results show that : i ) the m - lwdf algorithm is a viable solution for scheduling streaming flows in hsdpa ; ii ) this algorithm is unfair because it provides a better qos to users under favourable propagation conditions ; and iii ) a maximum node b queuing of 2 ~ 3 seconds represents a good compromise between cell throughput and delay jitter introduced in the node b for streanming
仿真結(jié)果表明, m - lwdf算法適合于hsdpa中流用戶的調(diào)度服務(wù),但它是一種不公平的算法,總是選擇為信道條件好的用戶提供更好的qos 。當(dāng)應(yīng)用于固定比特速率流業(yè)務(wù)時(shí),對(duì)m - lwdf算法作了一些修改,使得修正后的算法在用戶公平性上有了改進(jìn),但是不可避免地引起了系統(tǒng)吞吐量的下降。
