Acoustic field dynamics over submerged shoaling bathymetry. Two counter-propagating orbital pressure sources generate sum-frequency Doppler fringes, steepening along shallow refractive shelves before decaying into abyssal silence (深海干涉与折射声场).
The western terraces drop suddenly into cold sills where the soil behaves like dense brine. Two pressure eddies orbit an invisible ridge, casting sum-frequency interference upward through the silt. 声音沉入深槽，在浅滩处折射成细密的驻波条纹，直到被海沟彻底吞没。
Attempted continuous acoustic field interferometry using a depth-dependent phase velocity profile ($c \propto \sqrt{h}$) to emulate shoaling refraction without full Helmholtz integration. Two counter-rotating orbital point sources drive the Doppler shifts, steepening wavefronts over shallow shelf features. The character palette stepped cleanly from `·` through `█` without density blowout (variance 0.000199, edge activity 0.452). 浅水区波长压缩使条纹自动加密，深海区域则自然衰减至静默背景。
