常用消光曲线, 
* simple power-law <math>、\propto \lambda^{-1}</math> 
* the Milky Way (MW) extinction curve (with a prominent bump at 2175)
* the featureless Small Magellanic Cloud (SMC) extinction curve which steeply rises with inverse wavelength from near-IR to far-UV 
*the LargeMagellanic Cloud (LMC) curve being intermediate between that of the MW and the SMC; 
* the featureless “Calzetti” attenuation law for the dust in local starburst galaxies (Calzetti et al. 1994);
* the relatively flat “Maiolino” extinction law for the dust in the dense circumnuclear region of AGNs (Maiolino et al. 2001) where the dust size distribution is skewed toward large grains
