Time series of vertical crustal displacements are obtained by defining a datum of a stable group of 7 stations scattered in different regions with relatively small vertical displacements.
选分布于不同区域相对垂直位移较小的7个站为稳定点组，得到垂直位移时间序列。
Instead of a horizontal and vertical speed achieved with two rotors, the new base stations will use a single rotor with two diagonal sweeps leaning in opposite directions.
新基站将使用于有沿反方向倾斜的两个对焦扫描的单个转子，来代替两个转子的垂直和水平速度。
