在代理機制中,加入了知識檢索工具,它不但用於劃分形成簇,而且有效的把異質數據歸類。When a cluster of particles is immersed in a uniform electric field, the particles are coupled together due to the mutual interaction among them. this interaction causes the dipole moment of the cluster to be dependent upon the spatial arrangement and relative permittivity of the particles and upon the cluster size. in this work, we attempt to estimate the dipole moment of finite cubic arrays of particles, in terms of that of particle chains which has been known. we assume that a chain may be replaced by a single equivalent sphere with the same dipole moment. with replacing the chain by equivalent sphere, a cluster is simplified to a planar array, and this planar array is simplified to a chain, then the dipole moment is obtained. numerical calculations are performed. it is found that our results are acceptable
置於均勻電場中的一簇球形顆粒,由於其內部的相互作用而耦合在一起.這致使簇的感應偶極矩與簇的幾何結構,大小以及顆粒的介電常數等參量有關.試圖通過已知的鏈的偶極矩確定任意大小長方結構的簇的偶極矩.假定顆粒鏈可以被具有同樣偶極矩的一個等效介質球代替,並將具有空間結構的顆粒簇處理成面結構簇,再將面結構簡化成一個顆粒鏈,從而確定簇的偶極矩.在這一過程中,通過不斷增加等效球的尺寸,將顆粒間的相互作用包含在簇的偶極矩中.數值分析了立方結構簇的偶極矩,結果是可接受的3. by using the techniques of an explicit criterion to determine the number of real roots of a univariate polynomial in ( [ 13 ], [ 73 ] ) ; b - net form of bivariate splines function ; discriminant sequence of polynomial ( cf. [ 13 ], [ 73 ] ) and the number of sign changes in the sequence of coefficients of the highest degree terms of sturm sequence, this paper determines the number of real intersection points two piecewise algebraic curves whose common points are finite. a lower bound of the number of real intersection points is obtained in terms of method of rotation degree of vector field
大連理工大學博士論義:分片代數價線i片代數簇的若十m穴3 :利用楊路,張景中,侯曉榮在文獻v13 , 73 )中關於一元多項式實根的顯式判準,以及二元樣條函數的b網形式,多項式的判別序列和sturm序列的最高次數項系數序列的變號數,本文給出了兩個分片代數曲線的丈交點數(假設公共點是有限的)的計算公式。Abstract : when a cluster of particles is immersed in a uniform electric field, the particles are coupled together due to the mutual interaction among them. this interaction causes the dipole moment of the cluster to be dependent upon the spatial arrangement and relative permittivity of the particles and upon the cluster size. in this work, we attempt to estimate the dipole moment of finite cubic arrays of particles, in terms of that of particle chains which has been known. we assume that a chain may be replaced by a single equivalent sphere with the same dipole moment. with replacing the chain by equivalent sphere, a cluster is simplified to a planar array, and this planar array is simplified to a chain, then the dipole moment is obtained. numerical calculations are performed. it is found that our results are acceptable

該演算法選擇基於質心利基於代表對象方法之間的中間策略,它不用單個質心或簇中全部對象米代表一個簇,而是選擇數據空間中定數目的只有代表性的點,這些點代表和捕捉到了簇的形狀。此外,由於引入了收縮因子使代表點向簇小心「收縮」而使該演算法能夠較好地消除孤立點的影響,在處理孤立點上也更加健壯。分享友人
