摘要:

实验发现,当直流电流通过由两个超导体并联组成的电路,并在其中一个支路达到临界值时,支路中的电流发生准谐波无阻尼振荡。讨论了自激振荡产生的机理。研究了自激振荡电流电路中磁场冻结的特性。

英文摘要:

It has been found experimentally that when dc current is passed through a circuit consisting of two superconductors connected in parallel and reaches its critical value in one of the circuit branches the current in the branches undergoes quasi-harmonic undamped oscillations. The mechanism resulting in the appearance of the self-oscillations is discussed. The characteristics of magnetic field freezing in a circuit with self-oscillating current are examined.
