电力地

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

考虑了包括子磁滞回线磁滞模型,较准确地描述了电力变压器励磁支路。

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.

早期电力工人将它用作涂料，隔线圈，还将注满了紫胶纸层层地压紧制成单独绝缘物。
