This means that near the north or South Pole you are actually closer to the centre of the earth-where the Angle is being measured from-than you would be at the equator.
这就意味着，如果你身处南极或北极附近，你离地心的距离就比在赤道更近一些——纬度的测量就与地心有关。

Taper Roller Bearings transfer the loads acting on the bearing at a certain angle, the so called alpha contact angle towards the shafts centre line, (see sketch below).
圆锥滚子轴承的负荷作用于轴承在某一个角度，即所谓的阿尔法对轴中心线的接触角，（参见下图）转移。
