A new kind of uniformly accelerated reference frames with a line-element different from the Moller and Rindler ones is presented, in which every observer at x, y, z = const. has the same constant acceleration. The laws of mechanics are checked in the new kind of frames. Its thermal property is studied. The comparison with the Moller and Rindler uniform accelerated reference frames is also made.
