It depends on the device.

in this command what is the relationship between pixel and
point(1/72inch)?

There is no inherent relationship, it depends on the resolution of the
device.

or what is the relationship between pixel and 1 pcl unit or dot?

A PCL unit is normally a decipoint.

who can help me?
thank you very much!

Have you looked up "pixel" and "dpi" in Wikipedia?
