THE POLE ASSIGNMENT FOR THE SYSTEM WITH MULTIPLE INPUT
有重谱的多重输入系统的极点配置

In this paper,by using the convergence theory of unconditional basis,the problem of poleassignment of discrete spectrum operators with multiplicity spectrum is discussed.Some con-ditions which can alter the spectrum set of A into a given point set without any demand forspectrum separation of A are given.These results are the extension of the main result in 4,7].
