| 摘 要： | 直接利用华北ＧＰＳ监测网各个测点的位移观测值，借助高斯型位移协方差函数通过最小二乘配置建立连续分布的位移函数，并根据应变与位移的偏导关系，对华北ＧＰＳ监测区１９９２～１９９５年、１９９５～１９９６年最大剪应变及面膨胀连续分布进行估算，得到其应变场动态图像。 |
| 关 键 词： | 地壳应变 最小二乘法 最大剪应变 面膨胀 |

| Abstract: | Directly using displacement observed values of GPS monitoring network of north China, through least square collocation and Gauss type displacement covariance function, continuously distributed displacement function is established. Moreover, according to the partial derivative relation between displacement and strain, the continuous distribution of 1992～1995,1995～1996 maximal shear strain and surface expansion of GPS network of north China are estimated, and the dynamic pictures of its strain field are obtained. |
| Keywords: | crust deformation least square method Maximal shear strain surface expansion |
