摘要: 本文根据1977和1979年利用ZYZY型海洋重力仪,在中国东海及邻区获得的重力测量数据,对仪器的测量精度再次进行了评定,编制了自由空间异常,布格异常和地壳厚度等基础图件,参考有关地质和地球物理资料,对研究区的地壳结构特征进行了初步探讨。

Abstract: The measuring accuracy of the ZYZY-type Sea Gravity Meter,developed by Seis-mological Institute of State Seismological Bureau,was re-determined by sea gravity data that had been obtained during 1977-1979 in the study regions.The basic contours of free-air gravity anomalies,Bouguer anomalies and crustal thickness etc.were compiled.The characteristics of the crustal structures for the region in question were investigated with reference to geological and geophysical data.
