This paper analyzes the relationship between perpendicular baseline and terrain height sensitivity firstly, based on height error induced by uncertainty of phase.
根据测量相位不定性引起的高度误差，分析了垂直基线与地形高度灵敏度的关系，并推导了垂直基线与高度模糊数的关系式。
In the perpendicular direction to the rotation axis of the petal, the repeat position error is most sensitive to the position error of the locking force.
在对接面内与旁瓣转轴方向相垂直的方向上，重复定位误差对锁紧力位置误差最为敏感。
The velocity gradient, especially the perpendicular velocity gradient, leads the measuring error of flow angle with cylindrical probe to be larger than with conical multi-hole probe.
梯度使气流方向测量值向负梯度方向偏转。圆柱探针和锥形多孔探针相比，气流方向测量误差对速度梯度更敏感，纵向梯度对俯仰角测量值的影响尤其大。
