昆明台对 GS-15型重力仪在自动记录时测定记录比值的方法有二个步骤:第一,用拉读数弹簧的方法求出仪器输出的电讯号与重力值的关系;第二,输入一个直流电讯号给记录器,求出记录器上的单位长度与电讯号的关系。再通过这二个关系,求得记录器上单位长度所表示的重力值——记录比值。 记录比值标定的要求 地震观测系统中,GS-15型重力仪所观测到的资料,一是利用重力值随时间的变化来研究它与地震的关系,二是利用来研究重力固体
Kunming station on the GS-15 Gravimeter in the automatic recording method to determine the recording ratio has two steps: First, using the spring reading method to find the instrument output of the relationship between the electrical signal and the value of gravity; second, enter a DC signal to the recorder, find the recorder unit length and the relationship between the electrical signal. Through these two relations, we can get the gravity value recorded by unit length on the recorder - record ratio. Record ratio calibration requirements Observatory system, GS-15 gravimeter observed data, one is the use of gravitational value changes over time to study its relationship with the earthquake, the second is the use of gravity to study the solid
