N: Centrifugal force pushes it toward the point furthest, away from the pointofrotation.
尼基：离心力会把汤甩向最远的一点，远离旋转点。

The curl actually measures twice the angular speed of a rotation part of a motion at any given point.
旋度实际上衡量的是，在任意给定点,运动旋转角速度的两倍。

The seismic source USES the rotationof centrifugal quality to produce seismic energy. The produced sweep signals are recorded by clockwise and counter clockwise rotation at each source point.
