High speed, big package, ac motor drives beam directly, controlled by PLC. Stepless speed regulated by inverter, winding at a constant linear speed.

高速度、大卷装、交流电机直接拖动经轴，并由plc控制，变频器实现无级调速，恒线速卷绕。

Obviously-- and that's a bad way of saying it, I said constant the previous time-- in the linear case, it's subtract by certain amount.

这么描述很不准确，我之前在，线性算法中也说了常数,它是每次减少固定的量。

That one's not so obvious. So let's think about this for a second. To sort a list in linear time, would say, I have to look at each element in the list at most a constant number of times.

所以让我们来思考一会,要在线性时间能排序，列表里每个元素最多被使用常数次,不一定是一次，对吧。
