row-by-row method
1.By using the row action method and the dividing?conquering strategy, this paper puts forward an iterative dividing?conquering algorithm to solve arbitrary systems of linear algebraic equations ?AX=b(A∈R??n×m?)?. It is proved that the algorithm is convergent for arbitrary consistent systems of linear algebraic equation. The acceleration techniques of the algorithm and its prospective application to MIMD parallel iterative algorithm for the system of linear algebraic equations are discussed.
4.This paper introduces the technology of access and modifying SQL Server BLOB data by using ADO Stream of VB to establish ActiveX Server Component,achieve any image file of JPG/GIF,upload to Server and then save to the row of image in SQL Server 2000 in order to read image data from the row of image in SQL Server using Get Chunk method and Append Chunk method which are provided by ADO object in ASP,and achieve image and text display in the browser document server.
6.When the kinetic energy matrix have been diagonalzed, under the condition A=aE or A≠aE,the common method of finding normal coordinate is given. Besides,other two methods of finding normal coordinate are given,one method is by changing the coordinate scales and diagonaling the new kinetic energy matrix, the other method is by changing the coordinate scales and using arbitrary row of adjoint matrix of the frequency eigen matrix.
9.A new method to reconstruct the reciprocal primitive cell has been developed based on crystallographic geometry. Different from the conventional geometric figure|forming method, there is no need for the angles between the reciprocal planes and usually only three diffraction patterns with a row of same reflections are required, which could simplify the electron diffraction operation. The Bravais lattice type and parameters of β-Si-3N-4 has been determined by using this method.
