I used 3DS Max6.0 to create a plane, and use a target camera to look at it. If this camera is in one side, in camera view, I can see this plane; But, when I move the camera to other side(also change the look at direction), I cannot see this plane, seems I can see thru this plane. My question, if I don't use 2-side property in "shader basic parameters" nor use light, how I can see the plane in both sides.

You would have to create an 'extra plane' on the other side. For instance:

1. Turn the plane into an 'edit mesh'-object (right click, bottom right).
2. Go into sub-edit mode, polygon.
3. Set the camera so you a viewing the plane from behind (so it's see through)
4. Select 'create polygon'.
5. You should see the corner vertices now. Select them one-by-one in a counter-clockwise direction.

You should now have created two extra triangles pointing the other way. I'm not sure about the buttons, since I don't have Max in front of me now, but you should be able to find them.

Rightclick the plane, click properties, make sure backface cull isn't checked. If that doesn't work do what rick_appleton suggests, but in a faster way:
Convert to editable mesh, press '4', ctrl+A, shiftclick the selected plane (with any manipulate tool, not the select tool) choose clone to element, scroll down and click 'Flip' in the editable mesh toolbox.

Anyway, the backface-cull thing won't work in renders, only in the viewports...
