摘　　要：研究积分算子半群的Yosida逼近,证明了积分算子半群可以表示为一簇一致连续算子半群积分的极限,获得了积分算子半群的一个表示公式.Yosida approximation of integrated operator semigroups is studied and that integrated operator semigroups can be represented as integral limit of a consistent cluster continual operrator semigroup is proved, as a result, a representative formula of integrated operator semigroups is obtained.
