| Abstract: | This paper systematically analyses the state, site condition and other situation of fixed deformation station network in Gansu Province. The observation precision is evaluated by some quantitative indices, and the difference causes and improving measures are presented. The data observed at Gaotai and Lanzhou stations are analysed. And anomalous indices in the data and monitoring ability to mid-strong earthquake of the two stations are also discussed. |
