BCK代数的极大元扩张及其理想

The Extension of Maximal Element with Its Ideals of BCK-algebras

引入BCK代数X的一种新的扩张方法──极大元扩张，这种扩张对X没有限制条件，且对X的每个元素都可以有一种扩第；着重刻划了极大元扩张的几种常见理想。

The extension of the maximal element, a new expansible method of BCK-algebras X is introduced in this essaics. It has no limited conditions for X, but every elements can be extended. The essaies em[hasizes a few common ideals on the extension of the maximal element.
