摘要：
We present radial velocity observations of the dwarf novae KT Per and TZ Per, that allow us to improve their orbital parameters. For KT Per we find an orbital period of 0.16265777+/-0.00000001 days and a semi-amplitude K-em = 136+/-6 km s(-1), while for TZ Per an orbital period of 0.2629062 +/- 0.0000008 days and a semiamplitude K-em = 107 +/- 3 km s(-1) are found.
