MEASUREMENTS OF ANNUAL DEPOSIT MASS OF COSMIC DUST BY DEEP-SEA SEDIMENTATION
<正> We measured the annual deposit mass of cosmic dust on the Earth based on average sedimentation rate and content of cosmic dust at 20 surface stations on the Pacific investigation area (6°—13°N, 166°—178°W). The results indicate that measured results of each station are more identical and in accord with most measured results in the past, too.
