  The n-qubit real equally weighted states are employed in some quantum
algorithms including Deutsch-Jozsa, Grover, Simon, and so on. We qualitatively
investigate the entanglement properties of n-qubit real equally weighted
states. Firstly, all of the n-qubit real equally weighted states are classified
into 7 parts by means of their structural degrees. Then we analyze the
multipartite entanglement features of the states in every part by means of
separable and similar degrees.
