我们引入了Easton折叠，并证明了Easton折叠的两阶段迭代给出了一个模型，在该模型中，正则基数的后继者携带一个强饱和过滤器。这使得人们可以得到一个模型，在该模型中，许多后续基数只需迭代Easton折叠就可以携带饱和滤光片。
We introduce the Easton collapse and show that the two-stage iteration of Easton collapses gives a model in which the successor of a regular cardinal carries a strongly saturated filter. This allows one to get a model in which many successor cardinals carry saturated filters just by iterating Easton collapses.
