摘要	KUV 11370+4222 is a ZZ Ceti star discovered in 1996, which has not been observed since then. We performed observations for KUV 11370+4222 in 2010 January. From the Fourier transform spectrum of the light curves, 10 independent modes are detected. We searched for the best-fitting model by using the observed periods to match the model periods and obtained it with the total mass of 0.625 M-circle dot, the effective temperature of 10 950 K, and the helium mass fraction and hydrogen mass fraction of 10(-2.2) and 10(-4.0), respectively. We have found a triplet of frequency split by rotation, which are l = 1 modes. Using the frequency shifts, we estimate a rotation period of 5.56 +/- 0.08 h. Besides it, another l = 1 mode is identified. The other observed periods are identified as l = 2 modes. At last we investigated the property of the mode trapping.
