摘要
所谓"实数域上的微分中值定理可以推广到复数域上"的论断值得商榷.通过给出实例的方法,具体分析所谓的"解析函数的微分中值定理"之错误所在.
The argument that the differential mean-value theorem can be extended from the real number field to the complex field is worthy of discussing. Based on examples analyzing, the mistakes in the differential mean-value theorem of the analytic functions is discussed in detail.
