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.
经OM和TEM观察表明,当未变形奥氏体以10~30℃/s连续冷却时,贝氏体铁素体优先在奥氏体晶界处形核,然后呈板条状从奥氏体晶界向晶内长大,并且可以从最终的组织看到原奥氏体晶界。

目的:观察未变性乳清蛋白对支气管哮喘儿童GSH和GSH-PX的影响。
