王强华 %A 王炜 %A 姚希贤 %J 物理学报 %D 1991 %I %X We have analysed the circularly symmetric sine-Gordon equation with bias and dissipation by means of a simplified perturbation theory. Analytic solutions that describe the dynamical behaviour of a quasisoliton trapped within the annular junction have been obtained. Between the results of our theory and numerical simulation, there exists a good agreement for the first zero field step (ZFS) in the l-V characteristic. A brief discussion of our results is also presented. %K Josephson结 %K 孤子解 %K 微扰分析 %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=6E709DC38FA1D09A4B578DD0906875B5B44D4D294832BB8E&cid=47EA7CFDDEBB28E0&jid=29DF2CB55EF687E7EFA80DFD4B978260&aid=FCDBEA92FC3749B08845E838D20AA68F&yid=116CB34717B0B183&vid=1371F55DA51B6E64&iid=59906B3B2830C2C5&sid=B914830F5B1D1078&eid=2DD7160C83D0ACED&journal_id=1000-3290&journal_name=物理学报&referenced_num=0&reference_num=0
