Moreover, differences also exist between the pitchradius increasing phases and pitchradius decreasing phases.
此外，这种差异也存在于节径增加和节径减少阶段。

The result of simulation indicates that, by determining pitchradius appropriately, the system driver can be used more effectively and the cost of project can be saved.
仿真结果表明：适当选取下平台铰点支座分度圆半径能更充分地利用系统的动力源，提高工程的经济性。

The influence of coverage due to the radius, angular velocity, pitch , double thread of plastic screw, and rotational mode of steel axis are also discussed in here.
