Objective To develop a mouse model of premature ovarian failure (POF) by chemical treatment or radiotreatment.

目 探讨用化学药物及放射性处理，建立小鼠卵巢早衰动物方法。

It is shown that expansible ettringite forms in the topochemical reaction,and crystallizes in-situ on the surface of unhydrated aluminate minerals and orients radially.

发现够产生膨矾石是由局部化学反应所生成；它们在未水化铝酸盐矿物表面原地结晶，呈放射状生长。
