| Abstract: | Using the Gauss type function, covariance matrix of displacement data of different monitoring nets which have a scattered distribution is imitated.Moreover, the method is applied in calculation of crustal strain field of Xinfengjiang area,Guangdong province.The results show that the method not only is simple,effective and stable, but also has a certain meaning in relating the scattered elements. |
