The quote mentioned how many minutes the ship saileth in an hour, and the reason for this is that in this case a minute isn’t a unit of time, but a measurement of angle.
其实，上面一段引文中的第二个minute并非时间单位。它不是我们熟知的“分钟”，而是角度单位：分。
If you look at a clock and the time is 3:15, what is the Angle between the hour and the minute hands?
如果你看时钟的时间是3：15，什么是之间的夹角小时和分钟的手里？
The circular arc automatic door is reciprocating swing, and its motion parameters are the number of swing per minute, the size of the swing Angle and the travel speed ratio coefficient.
圆弧形自动门是往复摆动，其运动参数是每分钟摆动次数、摆角大小和行程速比系数等。
If you look at a clock and the time is 3:15, what is the Angle between the hour and the minute hands? (the answer to this is not zero!)
如果你看表的时间是3：15，那么时针和分针所成的角度是多少(答案不是0…)！
Simulation and experimental results show that the tracking accuracy of the main axis control system is not bigger than 1 Angle minute and this fulfills the demands of ATP system.
仿真和实验结果表明，主轴控制系统的跟踪精度在1以内，满足AT P系统对精度的要求。
