positive motion

In the gravitational field of the earth, negative energy corresponds to bounded motion and positive energy to unbounded motion.

在地球的重力场中，负的能量相应于有界限运动，正的能量相应于无界限运动。

The current is in the same direction as the motion of the positive particles.

电流方向与带正电的粒子运动方面相同。

Independently designed the organization, which use the direct current machine to make gear reduction, and with the screw rod and the nut organization, the electrical machinery the positive and negative circumvolved motion changes into the straight line translational motion of the control accelerator tension bar.

自行设计了利用直流电机带动齿轮减速机构并通过螺杆与螺母机构把电机的正负旋转运动转化为控制油门拉杆的直线位移运动的执行机构。
