摘　　要：本文研究了Furuta型算子不等式问题.利用Lwner-Heinz不等式和Uchiyama不等式,把关于两个算子的保序不等式推广为多个算子的情形,从而推广了Furuta的结果.In this article,we study the problem of Furuta-type operator inequality.By using the Lwner-Heinz inequality and an Uchiyama inequality,we extend an order preserving operator inequality from two operators to several operators,which is a generalization of Furuta＇s result.
