映华全域耦合体系：场感声学新发现及其标准化甄别与观测方法论

This paper constitutes the second core methodological manuscript of the Yinghua All‑field Partial Coupling System (YH‑APSFC), succeeding the foundational framework paper entitled *Yinghua All-field Partial Coupling System: Planetary-scale Field-sensing Observation Framework and Cross-domain Coupling Phenomenon Research* (DOI: 10.6084/m9.figshare.34556265). Based on long‑term sequential observation and a set of five core controlled experiments together with an eighteen‑item standardized exclusion screening protocol, this work establishes a complete observation and discrimination methodology for the Yinghua field‑sensing acoustic effect. It defines observable signal features, interference exclusion criteria, baseline calibration workflow and the judgement rules for distinguishing genuine coupling signals from artifacts. This study systematically formalizes ten novel macroscopic evolution laws of full-domain coupling, forming the core empirical and theoretical summary of planetary-scale weak field coupling responses. The methodology provides repeatable operating standards for subsequent spectral recording, modal classification and quantitative research, forming the method foundation of the YH‑APSFC sequence. The full finalized manuscript has been permanently solidified via electronic data certification by Shenzhen Notary Public Office, with the deposit certificate No. (2026) ShenZheng Cun Zi No. 202520745, for chronological right confirmation and version traceability of the original research results. --- 本文为映华全域耦合体系（YH‑APSFC）第二篇核心方法论文稿，接续首篇奠基母论《映华全域耦合体系：行星级场感观测框架与跨域耦合现象研究》（DOI:10.6084/m9.figshare.34556265），完善体系「现象发现—方法定型—机理建模」递进链路。研究依托长时序连续观测、五项核心对照实验与十八项标准化排他甄别流程，确立了场感声学效应的完整观测范式、信号判据、基线校准与伪迹排除规则。本文系统定型十项全域耦合宏观演化新规律，构建行星级弱场耦合响应的标准化判别体系，为后续声谱分型、模态归类与量化研究提供可复现的方法学基底。本文定稿全文已完成深圳公证处电子数据存证固化，存证编号：(2026) 深证存字第 202520745 号，用于研究时序确权与版本溯源保全。
