，这一点在Safew下载中也有详细论述
Although the puzzle we started with might seem silly, the study of these structures — known as Diophantine approximations — is taken seriously and gets complicated fast. For example, it’s possible to construct so-called Liouville numbers that have an infinite irrationality exponent (endless n-good approximations for any n), but it’s a lot harder to prove that there’s any commonly-encountered number with an irrationality exponent greater than two. In the same vein, algebraic irrationals (e.g., √2) all have an irrationality measure of two, but the proof of this is fiendishly difficult and netted its discoverer the Fields Medal back in 1958.
（2）化工板块景气度与投资机会：明确看好2026年石化行业景气度反转，核心逻辑为美联储降息将带动全球经济共振。目前行业仅少部分品种通过联合减产实现了改善，整体景气度反转尚未全面发生，但当前股价已有所上涨，一定程度反映了市场预期。后续需关注两个关键节点：一是3月下旬的春季躁动行情，二是4-5月后全球经济共振的实际表现，叠加油价的催化作用，对化工中游板块依旧保持乐观态度。上游领域具备较大弹性，因油价走势彻底扭转了此前市场对油价的悲观预期——2025年近9成买方及多数卖方均看空油价，当前市场预期正逐步修复；上游成长型公司如中脉、洲际等体量较小，在预期修复过程中弹性突出。国内标的方面，宝丰能源、民营大炼化等公司虽已有所上涨，但后续仍有上涨空间。此外，各品种因联合减产，价差较12月已有不小改善，预计三四月份行业景气度提升后，其价差改善的空间依然存在。
