摘　　要：对理想运算放大器特性,中文文献广泛采用“虚短虚断”方式加以描述,这一做法在英文文献中罕见。本人以前曾分析过用“虚短虚断”方式描述理想运算放大器特性存在的问题,提出可用“虚短实断(假短真断)”方式描述理想运算放大器特性。但文献[1]给出了反对本人观点的相关论述。文献[1]中存在许多问题,本文对其进行分析,并进一步论证“虚短虚断”描述存在的问题。For the characteristics of the ideal operational amplifier,the Chinese literature widely uses the way of“virtual short and virtual open”to describe,which is rare in the English literature.The problems in“virtual short and virtual open”describing have been analyzed in another paper before,and it was proposed to describe the ideal operational amplifier with the way of“false short and true open(virtual short and real open)”,however,these viewpoints are objected by literature[1].There are many problems in literature[1],this paper analyzes them,and further demonstrates the problem in“virtual short and virtual open”describing.
