如上图所示，根据以往的模式，存储器市场增长率呈现四年周期性波动，在2017年中期达到峰值，2019年中期触底，2021年下半年再次达到峰值，2023年中期触底。按照这种模式，人们可能会预期峰值出现在2025年，谷底出现在2027年。

Definition 1 A covering space of a topological space \(X\) is a topological space \(C\) together with a continuous surjective map \(p: C \to X\) such that for every point \(x \in X\), there exists an open neighborhood \(U\) of \(x\) such that \(p^{-1}(U) \cong F \times U\) for some discrete set \(F\) (called the fiber over \(x\)), and the map \(p\) restricted to each component of \(p^{-1}(U)\) is a homeomorphism onto \(U\).
