提出了一种用于 2G 磁带厘米级双环超导电路的无开关高温超导磁通泵和电路模型。磁通泵机构$-$不使用行波磁波$-$，其工作原理是在多重连接的超导电路的不同臂中产生有限电阻率，从而形成驱动超导持续电流的非零直流电压。利用磁通守恒、磁通流和动态阻力的原理，给出了与初步数据定性一致的理论模型。
A switchless HTS flux pump and circuit model for a centimeter scale double-loop superconducting circuit of 2G-tape are presented. The flux pump mechanism $-$ which does not use a traveling magnetic wave $-$ operates via the generation of finite resistivity in the different arms of the multiply-connected superconducting circuit, resulting in the build up of a nonzero dc voltage which drives a superconducting persistent current. Using the principle of flux conservation, flux flow, and dynamic resistance, a theoretical model is given which is in qualitative agreement with the preliminary data presented.
