First, the Wuhan Institute of Geology Beijing Graduate Department of gravity test and gravity exploration test a. Explain the following terms or terms (20 points) 1. Gravity Abnormal. 2. Remaining density and remaining mass. 3. Gravity anomalies are positive, anti-problems. Gravity measurement of the dynamic method and static method. Gravitational horizontal gradient and gravity horizontal gradient vector. Second, a brief description of gravity meter observations of the external correction (latitude, altitude, the middle layer and topography correction) and practice. (20 points) Third, the domestic ZSM quartz spring gravimeter elastic system measurement (gravity changes) principle (sketch) and temperature compensation principle, and explain the “zero (offset) reading method” and its role.
