摘要：
We discuss the X-ray line emission as observed with the HETG on Chandra of a sample of CV spectra. A portion of the data have been fit with global models by Mukai et al. [Mukai, K. et al. Two types of X-ray spectra in cataclysmic variables. ApJ 586, L77-L80, 2003]; we analyze the same spectra using a line-by-line fit. The results are similar to those reported by Mauche et al. on EX Hya, but additionally cover the other CVs. A broad range of temperatures is indicated based on the H/He-like ratio of O, Mg, S, and Fe. (c) 2007 Published by Elsevier Ltd on behalf of COSPAR.
