层环和层域

Stratified Ring and Field

本文推广了环和域的概念，提出了新的代数系统———ｎ层环和ｎ层域。作为特例，当ｎ＝１时，即为普通的环和域。最后，举出了有关层环和层域的若干例子。

This paper has spread the conception of ring and field,and advance a new algebraic system,that is,n-layer ring and n-layer field:as special case,when n=1,they are ordinary ring and field.Lastly,we give several examples about layer ring and layer field.
