Abstract: The most simple case in the special relativity is taken as a reference in this paper，the restricted

Lorentz transformation is rewritten in a four -dimensional transformation form. The property of four - dimensional

Mink space is demonstrated and analyzed，the rotational meaning in the four-dimensional Mink space is also thrown

light up. The methods of analogue are used to derive Einstein’s superposition formula of velocity.

Key words: special relativity, Einstein's superposition formula of velocity, analogue, special Lorentz transformation, rotation transformation, orthogonal transformation, Mink space
