The observations by OM and TEM reveal that when undeformed austenite continuously cooled at 10 to 30℃/s,bainitic ferrite nucleated mainly at austenite grain boundaries,grown up like parallel lath into the bulk from the grain boundaries of austenite,and original austenite grain boundaries could be seen.
經OM和TEM觀察表明,當未變形奧氏體以10~30℃/s連續冷卻時,貝氏體鐵素體優先在奧氏體晶界處形核,然后呈板條狀從奧氏體晶界向晶內長大,并且可以從最終的組織看到原奧氏體晶界。
Objective: To investigate glutathione (GSH)and activity of glutathione peroxidase(GSH-PX) effect of undenatured whey protein on asthma children s erythrocyte.
目的:觀察未變性乳清蛋白對支氣管哮喘兒童GSH和GSH-PX的影響。
