我们为混合特征的环定义一个闭包操作，并验证该闭包是一个环。然后我们证明这种闭包产生的环相对于其方丹环具有良好的属性，并给出一个例子来表明在这种意义上不闭包的环不满足这些属性。
We define a closure operation for rings of mixed characteristic and verify that the closure is a ring. We then show that this closure produces a ring with good properties with respect to its Fontaine ring and give an example to show that rings that are not closed in this sense do not satisfy these properties.
