摘要

We study the inverse spectral problems of recovering Dirac-type functional-differential operator with two constant delays $a_1$ $a_{1}$ and $a_2$ $a_{2}$ not less than one-third of the length the interval. It has been proved that the operator can be recovered uniquely from four spectra when $2a_1+\frac{a_2}{2}$ $2 a_{1} + \frac{a_{2}}{2}$ is not less than the length of the interval, while it is not possible otherwise.
