网络释义

1)reference level,基准水准面2)horizontal datum,水平基准面3)gage datum,水位基准面4)datum plane for sounding,基准水平面5)sea level datum,水深基准面6)datum elevation of pump,水泵基准面

用法和例句

The horizontal datum and two-pass statics method gave minimum depth error on time section.

试验结果表明 ,采用水平基准面两步法静校正 ,时间剖面反演深度误差最小 ;当基准面远离地表时 ,水平基准面一步法静校正也会产生较大的误差 ;非水平基准面两步法或一步法静校正 ,基准面的起伏越大 ,反演的深度误差越大 ,甚至出现构造假
