I will briefly review various analytic approaches to understanding the\ncontents and properties of the hot X-ray emitting gas contained in clusters and\ngroups. Special emphases are given to the following three issues:\n(1)Reconstruction of the gas distribution in groups and clusters from a (joint)\nanalysis of X-ray, SZ and gravitational lensing observations; (2)Test of the\nanalytic density profiles of dark halos suggested by numerical simulations and\nempirical models with current X-ray data; And (3)the effects of preheating and\nradiative cooling on the X-ray properties of groups and clusters.\n
