The paper uses the tools about algebraic number theory to find a class of quartic algebraic integer ±p~(1/2)±q~(1/2),then,it is determined and proved that their minimal polynomial is [x2-(p+q)]2-4pq,and in their normal closure,there are four real inserts and no complex inserts.
用代数数论的有关工具,找到了一类Q上四次代数整数±p~(1/2)±q~(1/2),确定并证明了它们的极小多项式是[x2-(p+q)]2-4pq,其正规闭包有4个实嵌入且没有复嵌入。
