01Using this database

Definitions here are reading aids derived from the current module text. A term link opens the relevant physical assumptions and derivation; it does not replace them. Search either language, a symbol or an equation ID. The module filter separates symbols such as Ω, Φ and Ψ whose meanings change across modules.

02Length realization

An operational relation between a specified propagation path and its elapsed time. One-way and return geometries, synchronization and endpoint conditions must be specified; a unit definition does not determine moving-space or gravitational response.

03Reference process and cycle counting

A reference process supplies a shared counting standard; the measured process supplies the path, rate or period under comparison. A readout converted with a reference frequency must be distinguished from physical changes in the measured process. Counting identities do not replace response dynamics.

04Length Vector Effect

The directional response of ASD true spatial lengths to motion. The reference transverse length and motion-associated true length play different roles. The result retains Chapter 1’s forward/reverse construction and path-pairing conditions.

05Motion factor γ

In LVE, γ is defined using the relative speed divided by c and enters directional length relations. Its ASD spatial-response interpretation and derivation conditions are retained; a shared symbol does not import another theory’s derivation.

06Total mechanical momentum

Momentum obtained by integrating the inertial response of the core and accompanying field. Chapter 2 uses LVE geometry together with mass normalization and a constitutive angular inertial distribution; geometry alone does not determine it.

Related registered equations: ASD-WEB-DYN-007 · ASD-WEB-DYN-008。

07True interaction distance

The electromagnetic construction adopts the LVE true length as the interaction distance and applies an inverse-square law there. This is a constitutive choice. Forces obtained by differentiating with respect to true separation and reference coordinates require a virtual-work mapping before comparison.

08Area radius

The radial coordinate defined by spherical surface area in the spherical model. It differs from accumulated true radial distance. Tangential arc length already contains the area-radius information and does not acquire a second radial stretch factor.

09Linear expansion coefficient Ω

The dimensionless linear-scale coefficient of the static exterior gravity model, normalized to one far away. Coupling standard-process lengths and frequencies to it is an explicit input. It is not the slow angular frequency of a quantum envelope.

Related registered equations: ASD-WEB-GRV-002。

10Linear-density coefficient Φ

The inverse of the linear expansion coefficient in gravity. It is dimensionless, not a three-dimensional material density or the quantum effective field. Converting line scales to volume density requires the actual deformation’s volume ratio.

Related registered equations: ASD-WEB-GRV-002 · ASD-WEB-GRV-003。

11Spatial state X and gravitational potential Ψ

X is a dimensionless state variable defined as the squared linear-density coefficient. Ψ is a gravitational potential with units of speed squared, set to zero far away. The weak-field force on a slow test body also uses an external-energy coupling. This Ψ is not a complex envelope.

13Reference optical path

A propagation quantity combining true path length with standard-process counting conversion. Its integral divided by c enters reference propagation counts. Its weighting is not merely a Euclidean detour, and coordinate representation must not be counted as an additional effect.

14Continuum state field

An effective field with dimensions of length represents small displacement or normalized spatial-state variation; its meaning is fixed by the model. Continuum variables and their dimensions do not require a particular microscopic lattice.

Source context: Continuum Degrees of Freedom · Continuum variables and dimensions。

15Longitudinal compression degree of freedom

Divergence describes volume change at small deformation: positive divergence means expansion, while positive σ denotes compression in this module. These definitions do not identify a static gravitational background, a free longitudinal wave and a matter-associated structure as the same solution.

Source context: Continuum Degrees of Freedom · Divergence and curl have different roles。

Related registered equations: ASD-WEB-SD-003。

16Transverse sector and local rotation

The divergence-free transverse projection is related to local rotation, but full shear also includes symmetric traceless strain. Curl is twice local rotation; the entire transverse deformation cannot be reduced to curl alone.

Related registered equations: ASD-WEB-SD-004 · ASD-WEB-SD-001。

17Helmholtz longitudinal–transverse decomposition

Under decay or compatible boundary conditions, a field splits into curl-free longitudinal and divergence-free transverse parts. Zero-wave-number and harmonic components need global conditions. Geometric projection need not commute with propagation in an inhomogeneous constitutive model, so it does not guarantee dynamical decoupling.

18FCC-like microscopic candidate

A candidate microscopic implementation using face-centred cubic adjacency. Symmetry and neighbor geometry alone do not supply the complete dynamical matrix, stable particles or experimental response. The continuum core does not assume FCC is unique.

19Particle-topology candidate

A candidate physical picture for localized electron or proton structures, distinct from a solved field configuration. Finite energy, boundary conditions, topology, stability, moving families and external-field response each require demonstration.

Source context: How Can Spatial Dynamics Become Matter? · Three distinct levels。

21Accompanying field

A spatial response associated with a localized core and its preparation history, potentially including co-moving near fields, deformation and phase.

22Phase–momentum matching

The physical matching of total mechanical momentum to the field’s phase gradient. Relations involving modal energy, momentum and action additionally require single-excitation action and mass matching. Writing the de Broglie form does not independently close those inputs.

23Modal action

An action quantity relating mode energy, frequency and momentum for a specified mode and normalization. Matching a single excitation to the reduced Planck constant is an explicit condition, not a consequence of complex notation or normalization.

24Positive-frequency channel field Φ⁽⁺⁾

The positive-frequency effective field on a selected extended gapped propagation branch. Its channel, source and constitutive inputs precede the envelope approximation. It is not gravity’s dimensionless linear-density coefficient Φ.

Related registered equations: ASD-WEB-QM-012 · ASD-WEB-QM-013。

26Slow envelope angular frequency Ω

A slow frequency relative to the carrier, not the total field frequency. Scale separation from the carrier controls omission of the second slow-time derivative. It has frequency units and differs from gravity’s dimensionless expansion coefficient Ω.

Related registered equations: ASD-WEB-QM-014 · ASD-WEB-QM-016。

27Fourier standard-deviation widths

Position and wave-number standard deviations of a normalized envelope and its Fourier spectrum. The mathematical bound requires finite second moments and suitable boundaries. Momentum widths additionally require phase–momentum matching and do not automatically specify measured core-event statistics.

Related registered equations: ASD-WEB-QM-022 · ASD-WEB-QM-023。

28Conditional detection-position distribution

A position distribution obtained by normalizing event rates over a specified time window, thickness and active screen, conditional on detection. A squared-amplitude form depends on linear material response, energy conversion and efficiency. This normalization alone proves neither universal Born statistics nor exactly one record per excitation.

29Effective-envelope tunneling

A barrier boundary-value problem in a matched effective channel, with transmission defined by transmitted-to-incident flux. A decaying envelope in the barrier does not prove that the nonlinear matter core crosses it; core–field–barrier dynamics require separate closure.
