Note that you will need to change the key-frame types to linear, if you want the lava's speed to be constant.

注意，你需要改变关键帧类型为直线，如果你希望岩浆的速度保持恒定的话。

This function can make numerical control system according to the point in the X coordinates, as the diameter of the workpiece calculated value spindle speed, and the cutting speed to be constant.

该功能可以使数控系统根据刀尖所处的X坐标值，作为工件的直径值来计算主轴转速，使切削速度保持恒定。

Substantially more complex than previous aircraft, the new plane required the pilot to attend to the four engines, a retractable landing gear, new wing flaps, electric trim tabs that needed adjustment to maintain control at different airspeeds, and constant-speed propellers whose pitch had to be regulated with hydraulic controls, among other features.

And the rotation has to be both continuous and at a constant speed, which for the LZT is 8.5 revolutions per minute.
