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.
