      We propose to observe low temperature galaxy clusters, 2A0335+096  
    and S1101, to study the origin and evolution of intracluster medium  
    (ICM). ASCA enables us to measure the distributions of silicon,      
    sulphur, and iron of these clusters, which are crucial to study the  
    ejection mechanism of the interstellar gas from galaxies. Relative   
    abundance between iron and silicon group elements are also  important
    to estimate the initial mass function of stars which contribute to   
    heavy elements. Our observation will provide strong  constraint to   
    the gas ejection models.
