Changes of Cu, Zn, Fe, and Ca contents in hair during pregnancy;

孕期發(fā)中銅鋅鐵鈣含量的動(dòng)態(tài)變化

Objective\ To detect the trace content of iron in human hair.

①目的　測(cè)定人發(fā)中微量鐵含量。

This paper studies its origin and maintains that it comes from the word "bobo"(發(fā)發(fā)), which describes the sound of bounding and tail swinging of fishes.

探討它的來(lái)源,可以認(rèn)為它是由描摹魚(yú)兒擺尾跳躍之聲、貌的"發(fā)發(fā)"引申、發(fā)展而來(lái)的。
