It gets a maximum amplification value of 1 . 1 to 2 . 0 at the top of the wall . the ratios between accel 為了安全,本文建議改以6米為界限,墻高小于6米的可以不考慮地震慣性力沿墻高的增大。
With the background of telescience experiment application , this paper concentrates on the research of accel erated algorithm for n - body collision detection . the main contents in this paper include three aspects : framework for t3d system , teleprogramming , and accelerated collision detection methods 本文的主要研究內(nèi)容分為三個部分:大時延遙操作系統(tǒng)框架研究、遙編程技術(shù)研究,以及快速碰撞檢測技術(shù)研究。
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(diào)制激光尾流場加速( sm - lwfa ) 。
Based on the analysis , summing - up and comparison with the financing methods of foreign state - owned enterprises , suggestions are presented here to broaden the financing channels , to improve our financing environmeat and to accel erate the innovation of the property ownership system while at the same time qui ckening our steps in the reformation of our enterprise system 在對國外一些企業(yè)融資行為的分析、總結(jié)和對比的基礎(chǔ)上,建議我國在加快企業(yè)制度改革的同時,應(yīng)進一步拓寬融資渠道,改善融資環(huán)境和加速產(chǎn)權(quán)制度的創(chuàng)新。
