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

目的 探讨用化学药物及放射性，立小鼠卵巢早衰动物模型的方法。

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.

发现够产膨胀的钙矾石是由局部化学反所成；它们在未水化的铝酸盐矿物表面原地结晶，呈放射状长。
