摘要：
We calculate pre-Main Sequence evolutionary tracks with accretion rates growing with the actual stellar masses. We show that accretion rates growing at least as M-1.5 are necessary to fit the constraints on the lifetimes and HR diagram. Most interestingly, such accretion rates growing with the stellar mass well correspond to those derived from observations of mass outflows (Churchwell 2000; Henning et al. 2000). These rates also lie in the permitted region of the dynamical models.
