HETE-2 triggered 166 events from SGR1900+14 and SGR1806−20 in summer periods from June 18 2001 to September 8 2004. Among these events, 6 events were localized to SGR1900+14 and 53 events to SGR1806−20. We performed the energy spectral analyses of bursts from SGR1900+14 and SGR1806−20 using the data of theWXM and FREGATE onboard HETE-2. Wefind that thee nergy spectra of SGR1900+14 and SGR1806−20 are well described by a sum of two blackbody models with temperatures of ∼4keVand ∼11 keV.
