從異速生長律的縱向、橫向和切向三個角度將地理空間劃分為實空間、相空間和序空間，分別對應于空間系列、時間序列和等級序列三個層面，每個層面的測度各有自己的空間維度。基於「空間循環細分-等級體系-網路結構」的數理等價關系，利用rmi （關系-映射-反演）原則，成功地實現了城市系統宏觀模型的理論抽象，將空間復雜性問題表徵為簡單的指數式標度定律（包括數量律、規模律和尺度律） ，這一組標度律可以與一組冪次定律（包括具有分形性質的規模-數目律、異速生長定律和三參數zipf定律）互為變換。In general, a watermark system must satisfy the two basic requirements : imperceptibility and robustness. in this thesis, we proposed a frequency - based watermarking algorithm using toral automorphisms, in which a kind of toral automorphism is employed to mix a recognizable binary image ( bw ), which contains the copyright information, into a noise - like signal
演算法簡單描述如下：首先用一個環形自同構映射把要嵌入的數字水印映射成偽隨機噪聲，然後把該偽隨機噪聲嵌入到宿主數據頻域的低頻段中，接著把得到的頻域系數進行相應的逆變換得到嵌入水印的圖象，最後對該嵌入水印的圖象進行視覺掩蔽處理。After briefly introducing the background and exploring the cause of the socialist education movement, the paper points out the demand of farming on his own set forth after the great leap forward has a lot to do with the outbreak of the movement and argues the demand reflects the conflict between the prevalent peasant mentality and the collectivism
本文首先對社教運動的提出背景及成因進行了簡要分析，指出「大躍進」之後出現的「單干」現象是社教運動開始的重要原因，認為它集中反映了當時農村社會普遍存在的小農思想與集體主義思想的矛盾。Simplicity is the biggest advantage of sql maps over other frameworks and object relational mapping tools
簡單性是sql maps優于其他框架和對象關系映射工具的最大優點。Yes, all of the models in figure 1 could be improved, but i needed a simple example that showed how different object schemas mapping to the same data schema
是的，圖表1中的所有模型都可以改進，但是我只是需要一個展示不同對象模式怎樣映射到同一數據模式的簡單例子。The simplest explanation for these dizzying swings is that prices reflected investors ' expectations of future earnings
對這種大起大落的現象最簡單的解釋就是，股票價格反映投資者對股票未來盈利的預期。2. methods in frequency domain : through a comparative study, wedge and ring feature of fourier transform performs better than other features based on texture spectrum. it represents the directivity, coarseness and regularity of an image
在基於頻率域的紋理分析方法中，分析了基於傅立葉變換的紋理分析方法，經兩組對比實驗，楔環特徵能夠很好的反映圖象紋理的方向性、粗糙性和規律性，在檢索中明顯優于基於頻譜的簡單統計特徵。It is based on a set of practical data in some area. the nonlinear least - square method is used to work out the parameters of the mobile communication channels " model, and then the error sequence comes into being. the noise ' s model of automobile that can reflect the random characteristics of the noise is also founded
本論文採用簡單分群的markov二狀態模型建立移動通道概率統計模型，從某一移動通道實測曲線出發，利用非線性最小二乘法得出狀態模型參數，從而獲得移動通道的差錯序列；本文對汽車噪聲的產生以及它對信號的影響進行了詳細的分析，提出了汽車噪聲模型；並且採用尖脈沖模擬汽車點火噪聲脈沖，實現了噪聲對信號的隨機干擾，形象地反映了移動通道中信號的疊加過程。Ann ( artificial nerve network ) is the simulation of biologic nerve system. ann is a kind of network, in which a quantity of calculation cells ( nerve cells ) joint each other. although ann ca n ' t really reflect man ' s cerebral function, it is able to be an abstraction, simplification and simulation of the biologic nerve system, and it occupies a dominant position in economic prediction field
人工神經網路是人們對生物神經系統的模擬，是由大量的處理單元（神經元）互相連接而成的網路，人工神經網路雖然並沒有完全真實地反映大腦的功能，但它能夠對生物神經網路進行某種抽象、簡化和模擬，在經濟系統預測方面具有較大的優勢。The establishment of efficient traffic models to reveal fundamental traffic characteristics is an essential requirement in the design, planning and operation of transportation systems. cellular automata ( ca ) are non - liner dynamical system in which space, time and state values are discrete, using simply rules, ca has attained very good results in simulating several complex natural phenomena and physical problem. that enlightens people to simulate traffic flow by ca method. urban major road performs critically on dredging traffic, therefore, it is very necessary to study the control and manage for urban main - road
