The returning effect of soliton in an annular Josephson junction is analysed in detail theoretically. Some results are compared with directly numerical simulation ones. To avoid the return effect of soliton, the conditions which relate to the minimum bias current of the first zero step of annular junctions with different geometric and dissipative parameters are discussed. A disscusion of the difference between in-line and annular junction is also made.
