她将看到和观察者A一样数量的尺子。所以同样的，将可以做出这样的结论：圆周和半径的比率将和欧几里德几何不一致。
She would see the same number of rulers involved as did observer a, and so would likewise conclude that the ratio of circumference to radius did not conform with Euclidean geometry.
譬如，在几何学里我们必须假定，一个圆周的圈线是由无限多喝无限小的直线形成的。
Thus in geometry you are told to conceive the circumference of a circle as formed of an infinite number of infinitely small straight lines.
该方法通过测量XY, YZ, XZ平面内特定圆周上各点的空间误差，可获得所有21项几何误差。
All the 21 geometric errors can be obtained by the means of measuring volumetric errors on some specific circles in XY, YZ, XZ planes.
