Semi-classical limit of cubic defocusing nonlinear chrodinger system 非線性散焦立方薛定諤方程的半古典極限
In chapter one, we discuss the limit behaviour of a kind of symmetric random variables sequences, mainly including the strong law of large numbers, the convergence rates of tail probabilities in the law of large numbers and the convergence rates of tail probabilities in the law of large numbers with random index . the results obtained extand some results of classical limit theory under the independent situation 第一章主要討論了一類分布對稱隨機(jī)變量序列的極限性質(zhì),具體包括強(qiáng)大數(shù)定律、大數(shù)律尾概率級數(shù)的收斂性以及具有隨機(jī)足標(biāo)的大數(shù)律尾概率級數(shù)的收斂性,從而對獨(dú)立情形下的經(jīng)典極限理論部分結(jié)果進(jìn)行了條件的推廣。
For foundations subjected to loads varying in time in a non-proportional manner within prescribed limits, the limit equilibrium analyses based on the classical limit theorems may overestimate ultimate bearing capacity, as collapse under cyclic loads may occur at a level well below the static collapse loads 于是,在載荷空間可以給定一個(gè)區(qū)域,載荷在這個(gè)區(qū)域內(nèi)變化,結(jié)構(gòu)最終將進(jìn)入安定狀態(tài)。經(jīng)典安定理論早在上個(gè)世紀(jì)五十年代就已經(jīng)建立,并且一直有所發(fā)展,也為工程界所矚目。
When we applied the properties of quantum mechanics to information, classical limit of information theory could be exceeded in many ways, and we can accomplish many unimaginable tasks for classical information processing, such as fast factoring, tele-portation, absolutely secure cryptograph etc . the naissance of quantum information provided with reliable physical foundation for future revolution of information as well as new principle and method for development of information in 21 century 將量子系統(tǒng)的特性應(yīng)用到信息領(lǐng)域中,可以在許多方面突破經(jīng)典信息理論的極限,實(shí)現(xiàn)經(jīng)典信息處理難以想象的功能,如大數(shù)因子分解、隱形傳態(tài)、絕對安全的密碼等。量子信息科學(xué)的誕生為未來信息科學(xué)的革命性變革提供了可靠的物理基礎(chǔ),為信息科學(xué)在21世紀(jì)的發(fā)展提供了新的原理和方法。
