In each level you have to place an increasing number of parts into the circle, so you have to be quick or you run out of time.

每一个关卡你将有越来越多的在圆圈里的元素去完成，所以你必须要加快速度来节省时间。

The coaxiality tolerance assesses the deviation of the axis from the datum axis, while the radial run-out tolerance assesses the deviation of the circumference line from a coaxial circle.

同轴度公差评估的是轴线相对于基准轴线的偏差，而径向跳动公差则评估的是圆周线相对于同轴圆的偏差。
