摘要：
Recent observations of the Vela SNR in the ISM species Ca II and Na I are presented and discussed in the context of the "break-down'' of the Spitzer-Routly effect. Variations in line profiles with time are demonstrated, eventually through a statistical approach a description of cloud structure will be possible. The IS lines in similar to 70 sightlines are used to determine an accurate distance to the Vela SNR of 250 +/- 30 pc. Finally a discussion of future observations are given relating information obtained from measurements of near-by ISM to more distant intergalactic medium.
