The effect of misch metal and yttrium on the ageing behavior of AZ91 magnesium alloy was investigated.Aluminum compounds of rare earth and yttrium with high melting point were crystallized fiirstly from the melt alloy during the solidifying process and pushed to the crystalllizing face of α phase to inhibit its growing,or became the nucleation of the matrix.

Because of crude facilities or keeping clear of trouble, some teachers enjoy following the beaten track in their teaching and ruling their students by their voices alone. They use the monotonous methods such as punishing the students to transcribe words repeatedly, without any innovation in teaching scenes. In this way, the teachers make a language which is closed to students to be a kind of solitary and tedious mechanical repetition, and then they get half the result with twice the effort in the mass, even causing a lapse of misguidance.
