英文摘要	Within the time-dependent Ginzburg-Landau (TDGL) theory, we theoretically investigated the dynamic properties of vortex-antivortex (V-Av) pairs in a current-carrying superconductor strip with one tilted slit or two transversely/longtitudinally arranged slits in the presence of a weak magnetic field. The effect of the rotation angle on the resistive state in the sample with one tilted slit was considered. The location of phase slippage in the sample can be predetermined by the rotation angle of the tilted slit. We found the coalescence of the phase-slip lines (PSLs) during a periodic multiharmonic voltage oscillation. This leads to two stages of voltage oscillation at zero applied field and three stages at weak magnetic field since the coalescence of left and right PSLs are staggered in the latter case. Moreover, the influence of relative position and size of the two slits on the transport properties of the sample are also studied. The dynamic behavior of V-Av pairs depends on not only the slit length but also their horizontal or vertical interval distance between the two slits. Since the geometry of sample has an important influence on the distribution of supercurrent across the sample, we demonstrate the possibility to efficiently guide the kinematic vortices by adjusting the relevant parameters.
