摘要: Routine relative phase observations made during 1962 at Boulder on VLF signals radiated from NPM, Hawaii, and NBA, Canal Zone, have been analyzed to determine whether they show evidence of a semidiurnal lunar variation. It is found that the daytime NBA presence significant (at 5 per cent level) height variation 0.11 km; maximum occurs 2 hours before transit. The nighttime both NPM are not inconsistent with results. Some possible reasons for lower significance results discussed.
