垂直分量 [数] vertical component
normal component
- 测量定位的垂直分量精度的提高,受到中性大气延迟改正程度很强制约。
The accuracy of the vertical component in positioning is restricted strongly by the extent of correction for this kind of delay. - 强震前地磁垂直分量日变化异常主要表现在幅度与相位上的变化。
The diurnal-variation anomalies of the vertical-component in geomagnetic field are mainly the changes of phase and amplitude before strong earthquakes. - 根据位理论和挠曲均衡补偿理论,推导了重力梯度异常垂直分量与海深之间的关系。
Based on the theory of potential and flexural isostatic compensation, the relationship between ocean depth and the vertical component of gravity gradient anomalies is derived.
