操作员根据它，不需要直接观察目标，就可以召唤致命精度的炮火打击。
An operator can thus call down artillery fire with lethal precision without having to see the target directly.
这次获得的结果大约是以前观察的10倍，而Gebhardt 表示其原因主要是由于望远镜精度的提高补偿了地球大气层对光线的扭曲。
The measurements are about 10 times better than previous observations, largely because of telescope enhancements that compensate for distortions in Earth's atmosphere, Gebhardt added.
通过人眼观察进行识读的传统水准器式倾斜仪表，直观但精度不高、灵活性不强。
With traditional leveling survey type tilt instruments, the measurement is obtained by observation of human eye, so the accuracy is not high enough and the flexibility is low.
