摘要：
We propose a new empirical redshift indicator for gamma-ray bursts. This indicator is easily computed from the gamma-ray burst spectral parameters and its duration, and it provides pseudo-redshifts accurate to a factor two. Possible applications of this redshift indicator are briefly discussed.
