small vertical axial pump stations 小型立式轴流泵站
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。
Perhaps more convenient access to the information, this is the future, the success of the vertical class more and more stations.
或许由于信息获得更加便利,这才是未来,垂直类的站成功的越来越多了。
