<正>A solution of the impedance wedge diffraction problem has been given by Malyuzhinets in Ref.[1].The key to the problem is to seek the solution of Malyuzhinets functional equations.However,how to go about getting the solution of the functional equations is not given in Ref.[1].A detailedprocess to get the solution of the functional equations is provided by using the infinite product theoryin Ref.[2],in which,however,there exist some errors and indistinct places. In this paper,these errors in Ref.[2] are corrected and another simpler method to obtain thesolution of the functional equations is also provided for the purpose of comparison.
