文章回顾Loehr和Remmel的双射$\phi_n$，其将特定双统计量映射，本文给出更直接的$\phi_n$定义，更便于计算与处理，此为主要贡献。
AI 中文摘要
在这篇说明性文章中，我们回顾了Loehr和Remmel给出的一个显著双射$\phi_n$，它从大小为n的停车函数集到其自身，将双统计量（dinv，面积）映射为双统计量（面积，pmaj）。本文唯一的新颖之处在于我们对$\phi_n$的定义，它比原定义更直接，更易于计算和处理。
英文摘要
In this expository article we review a remarkable bijection $ϕ_n$ due to Loehr and Remmel from the set of parking functions of size n into itself, which sends the bistatistic (dinv, area) into the bistatistic (area, pmaj). The only novelty of the present work is our definition of $ϕ_n$, which is more direct than the original one, hence easier to compute and to work with.
