| Abstract: | On the basis of fine process of all the observation data of Longmenshan regional gravity network,the analysis method of statistic correlation is used to study the stability of the calculation datum in the classic indirect adjustment and its disturbance on adjustment results.The gravity changes in which calculation datum disturbance is corrected show that the gravity anomalyl before Wenchuan earthquake is obvious and its characteristics is distinctive.Thus the stability of calculation datum must be considere... |
