The Extension of the Maximal Element and the Principal Ideal on the Periodic BCK-algebras

引入BCK代数的一种新的扩张方法———极大元扩张 ;

The extension of the maximal element,as a new expansible method of the BCK algebras,is introduced in this eassy.The eassy lays emphasis on some peculiar properties on the principal ideals of the periodic BCK algebra and its extension of the maximal element.
