电力地

The model including subordinative hysteresis curve can describe the magnetizing branch more precisely.

考虑包括子磁滞回线的磁滞模型,较准确地电力变压器的励磁支路。

Early electrical workers used it as a coating to insulate coils, and molded it into stand-alone insulators by pressing together layers of shellac-impreg-nated paper.

早期的电力工人将它用作涂料，隔离缠绕一起的线圈，还将注满紫胶的纸一层层地压紧制成单独的绝缘。
