Query: Analytic Approaches to Understanding the Distribution and Evolution of
  Intracluster Gas   I will briefly review various analytic approaches to understanding the
contents and properties of the hot X-ray emitting gas contained in clusters and
groups. Special emphases are given to the following three issues:
(1)Reconstruction of the gas distribution in groups and clusters from a (joint)
analysis of X-ray, SZ and gravitational lensing observations; (2)Test of the
analytic density profiles of dark halos suggested by numerical simulations and
empirical models with current X-ray data; And (3)the effects of preheating and
radiative cooling on the X-ray properties of groups and clusters.
