| Abstract: | On the basis of the relationship between gravity difference and scale parameters in linear term of relative gravimeter,a method to detect the change of parameters in linear term has been developed,and the change of parameters in linear term of G793 and G854 gravimeter were studied from the gravity data of western Yunnan area from1989 to 1996.The results show that the change of parameters in linear term of relative gravimeter can be calculated with high precision,and the method is reliable for detecting noti... |
