By using the algebraic method, we obtain a new formula for the expected hitting time of random walks on strong-connected and aperiodic digrahs (irreducible and aperiodic Markov chain). From this formula, we obtain the explicit expressions for the expected hitting times of random walks on directed de Bruijn graph, directed Kautz graph and some graphs constructed from strong regular graph, etc.

The new antigen P3 peptide which harvested from the 430A peptide synthesizer were verified by the mass spectrograph and HPLC, that the ratio of mass/charge of the synthetic peptide was equal to the molecular weight in theory and its purity was above 95%. The Western blot analysis show that the antiserum induced by the new antigen plus hemocyanin could bind with the 22KD and 55KD proteins, which were existed in the testis tissue protein of mouse, rat and human.
