So for a classical system to give rise to a quantum one , it must lose information 古典系統(tǒng)包含的資訊比量子系統(tǒng)多,因?yàn)楣诺涞淖償?shù)可以是任意值,而量子的變數(shù)卻是不連續(xù)的。
A classical system contains more information than a quantum one does , because classical variables can take on any value , whereas quantum ones are discrete 他主張量子力學(xué)與古典力學(xué)間的明顯差異在于資訊的遺失。
My synthesis adopts the new classical system of marshall as the comparative benchmark and trailed along the century - long economics thought history to seek the most fundamental ideas of economics 我們要以馬歇爾的新古典體系為參照點(diǎn),前后延伸一百年,提煉和總結(jié)經(jīng)濟(jì)學(xué)最基本的思想方法。
We have studied two type of perfect potentials ( a dirac interaction and nonzero distance interaction ) existing between the two particles . the spectrum statistics and the corresponding classical system action have been given 計(jì)算了粒子間存在兩種理想短程作用勢(shì)(占作用勢(shì)和非零距離作用勢(shì))的情況,給出了系統(tǒng)的能級(jí)譜統(tǒng)計(jì)分布。
This thesis reports a study on the characteristics of some piecewise - smooth classical systems . the systems studied are a model of an rlc circuit with an analogy switch and a model of an electronic circuit with over - voltage protection and a dissipative element 本論文報(bào)道對(duì)一些分段光滑經(jīng)典系統(tǒng)的研究,涉及兩個(gè)分段光滑經(jīng)典系統(tǒng):一個(gè)帶模擬開(kāi)關(guān)的rlc電路模型和一個(gè)帶耗散性元件的過(guò)電壓保護(hù)電路模型。
At first , theories about system identification are systematically reviewed , including its contents and process . at the same time , the classical system identification methods are summarized , the advantage and disadvantage of these methods are analyzed . secondly , the history of nn is briefly reviewed , and the structure , function and algorithms of feedforward nn and the recurrent nn are particularly introduced 本文首先介紹了系統(tǒng)辨識(shí)的內(nèi)容,步驟和分類(lèi),對(duì)傳統(tǒng)的系統(tǒng)辨識(shí)方法作了總結(jié),比較了幾種方法的優(yōu)缺點(diǎn);并回顧了神經(jīng)網(wǎng)絡(luò)的發(fā)展歷程,詳細(xì)介紹了前饋型網(wǎng)絡(luò)與遞歸網(wǎng)絡(luò)的結(jié)構(gòu)、功能和算法以及在實(shí)際應(yīng)用中設(shè)計(jì)神經(jīng)網(wǎng)絡(luò)需考慮的問(wèn)題。
First , users cannot find the available parking space conveniently by themselves . it not only makes time waste and failure operation , but also leads to a huge waste of social energy resource . second , the increasing of the vehicle amount enlarged the difficulty of management and the safety disadvantage of classical system , the system no longer ensure every vehicle ' s safety 存在的問(wèn)題主要有:顧客置身于停車(chē)場(chǎng)中,不能方便快速地自主找到有效停車(chē)位,這樣不僅浪費(fèi)時(shí)間、影響停車(chē)場(chǎng)的正常運(yùn)行,也造成了對(duì)社會(huì)能源的巨大浪費(fèi);停車(chē)場(chǎng)中車(chē)輛數(shù)量的增加,管理難度加大,傳統(tǒng)停車(chē)場(chǎng)管理系統(tǒng)在安全性方面的缺陷更顯嚴(yán)重,已無(wú)法有效保證車(chē)輛的安全。
