A method is proposed to construct a localized active functional space from the density matrix of a large system. the large system is partitioned into central and surrounding areas. the active functional space is mainly localized on the central area. it contains all basis functions centered at the central area and all the orbitals which consist of the basis functions localized in the surrounding area and interact with the basis functions in the central area to a certain extent. an integral number of electrons are involved in the localized active functional space which can be considered as a relatively independent subsystem in the large system and for which formally isolated quantum chemical calculations can be performed. the related program has been coded and is checked through calculating the number of 4
報道了從大體系的密度矩陣出發構造定域于指定局部的活性泛函空間的方法和程序。將大體系劃分為中心區和環境區，活性泛函空間包含中心區的基函數及與其有相互作用的環境區軌道，容納整數個電子，構成大體系的一個相對獨立的子體系，可以在其中進行獨立的量子化學計算。通過計算鑭系氯化物和水合離子的4 -
The brief proof is given for " row elementary operations keep the linear relationship of column vectors of matrix ", by using multiplication of partitioned matrix and the relation between elementary matrix and elementary operation
摘要利用初等矩陣與初等變換的對應關系及分塊矩陣的乘法，給出「矩陣的行初等變換不改變其列向量組的線性關系」的一個簡易證明。 -
The essential idea was that an incomplete data set including missing values was partitioned into several fuzzy clusters by using local principle component with least variance, and through solving the general inverse matrix of the data to obtain the principle components of each sub - clusters, the missing values in clusters could be estimated based on local principal components utilizing a simple linear model
其基本思想是，先利用具有最小方差的局部主成分，把包含有遺漏值的不完備數據集劃分成多個模糊聚類，然後通過求解廣義逆矩陣來獲得各個子聚類的主成分，最終在局部主成分的基礎上通過簡單的線性方程模型去佑計聚類中的遺漏值。 -
