非负特征值反问题是确定一列复数σ为非负矩阵谱的充分必要条件的问题。本文完全解决了给定表σ中除一个（Perron特征值）外的所有数的实部小于等于零的问题。
The nonnegative inverse eigenvalue problem (NIEP) is the problem of determining necessary and sufficient conditions for a list of complex numbers σ to be the spectrum of a nonnegative matrix. In this paper the problem is completely solved in the case when all numbers in the given list σ except for one (the Perron eigenvalue) have real parts smaller than or equal to zero.
