本文作为前一阶段工作的小结,主要谈到我们所采用的磁场电流稳定器在实验中所遇到的一些寄生反馈,如电源反馈、漏电反馈、变压耦合反馈,以及由于它们所引起的系统工作不好的现象,如没有放大、放大不均匀、出现自激振荡等。也谈到了在克服这些不良影响对我们所采取的一点方法。 This article as a summary of the previous stage of work, mainly talked about the magnetic field current stabilizer we used in the experiment encountered some of the parasitic feedback, such as power feedback, leakage feedback, coupled feedback coupling, and as a result of their system Poor work phenomenon, such as no amplification, uneven amplification, self-oscillation occurs. I also talked about some of the ways that we have taken to overcome these negative effects.
