Mhchem 满箱

我正在使用mhchem内联包，方程式不会换行，因此会导致框溢出。有什么方法可以强制它们遵循换行规则吗？

即以下句子：

Clays exist in groups with generalised formulae, these include: 
the smectite group \ce{(A1/3D2-3[T4O10]Z2.nH2O)} and the serpentine group 
\ce{(D2[Si2O5](OH4)\pm nH2O)} among others.

这些公式看起来很可爱，它只是悬在边缘上。。。

表达式被装箱了，但是如果你稍微摇晃一下箱子，它就会在数学二元运算符周围断裂。（我不知道这对于所有 mhchem 构造是否完全安全，但至少在这里可以断裂\pm。）

在此处输入图片描述
