摘      要：TypeⅡb supernovae(SNeⅡb)that have a thin layer of hydrogen left in their outer envelope have been believed to belong to core collapse *** transfer via Roche lobe overflow can significantly change the nucleosynthesis and surface chemical elements of the progenitors of SNeⅡ*** aim to explore what conditions a close binary can meet with the observational features of SNeⅡ*** find that an observed low mass SNⅡb cannot be produced by a low mass isolated star with M20,M_(⊙)due to the existence of a thick hydrogen envelope regardless of *** dominate as progenitors in the mass interval(i.e.,M20 M_(⊙))considered in this *** 16 M_(⊙),primary with a 14 M_(⊙) companion in a binary system with~10 days P_(orb) 720 days can reproduce observational features of SNe Ⅱb(i.e.,T_(eff),log L/L_(⊙),M_(He),M_(H),etc.).With the decrease of the hydrogen-rich envelope mass,the radius of the progenitor *** associated types of SNⅡb progenitors from RSGs and YSGs to BSGs are closely related to the amount of hydrogen left in the *** can bring the production of the CNO reaction to the stellar surface at an early phase,which would explain the nitrogen-rich circumstellar material of SN 1993 J and can also explain the large He/H ratio of supernova *** can increase the corresponding region of the orbital period which can produce an SNⅡb.
