第2章 术语与符号(注册最小集)


I. 变量与符号(Variables & Symbols, 最小集)

内联符号一律用反引号;凡涉及路径量必须显式 gamma(ell) 与测度 d ell,并在注册卡数据侧记录 delta_form ∈ {general, factored}。


II. 统计与不确定度记号(Minimal UQ Notation)


III. 常量与参考量(Constants & References)


IV. 单位与量纲(Units & Dimensions)


V. 写法与冲突名约束(Mandatory Conventions)


VI. 统一口径示例(Normative Examples,可直接复用)


VII. 符号与字段注册(Machine-Readable,YAML 最小片段)
