方形簇種法
英文
square cluster planting method-
In the paper, li5mn4o83 + li5mn12o24 -, li5mn16o32 +, li17mn16o329 + clusters selected by " seed atoms " were calculated theoretically by means of the quantum chemical dv - xa calculation method. form the angle of electronic structure, the status of lithium ion and the electrochemical properties of lixmn2o4 were discussed preliminarily according to different conditions ( x = l, 2 ). based on calculation results, it ' s found that the jahn - teller distortion, which was thought to lead to poor cyclability, occurred during the discharge of lixmn204, and we also confirmed the formation of a novel phase with low energy after overdischarge ( x = 2 )
為了從微觀上認識錳系正極材料的結構和電化學性能之間的關系，本文提出了採用量子化學離散變分x （方法，對結合「種子原子法」選取的li5mn4o83 + 、 li5mn12o24 - 、 li5mn16o32 + 、 li17mn16o329 +等錳系正極材料的原子團簇進行了理論計算，從電子結構上初步探討了鋰離子嵌入正極材料后的存在形式以及鋰離子的嵌入對電極材料電化學性能的影響，同時還從結構上對鋰離子電池的循環性能和容量進行了初步的討論。The method can be used to filtrate the outlier data and discover clusters of arbitrary shape
這種方法可以用來過濾「噪聲」孤立點數據，發現任意形狀的簇。During the forming of clusters, transfer agents are necessary which overcome the disadvantages of gqm
在簇的形成過程中加入了轉換代理機制，這種機制克服了gqm方法的缺陷。( 1 ) hsmbk, it uses the bisect partition principle and adopts a new method to count the comparability - - " binary feature sparse otherness ". we apply the thought of choosing excellent element to the method of calculating the center of clustering for reducing the effect of the isolated points. at last, we bring forward jw rule based on the enlighten idea
（ 1 ） hsmbk演算法，利用了對稱劃分原理；採用了一種新的計算相似性方法- -布爾特徵稀疏差異度；將選優思想應用到聚簇中心的計算，形成一種新的中心計算方法，減少了孤立點的影響；採用啟發式思想提出了jw準則，為k值的選擇提供依據。The main results of our paper are as follows : present a chinese text clustering model ; obtain a chinese text algorithm which can select better initial point and a dbtc clustering algorithm which can identify cluster with any shape
本文獲得的主要結果：提出了一個中文文本聚類模型，提出一種選取初始聚類中心的中文文本聚類演算法和一種能發現任意形狀簇的dbtc聚類方法。分享友人
