The so-called scientific and technological core (statistical source) database refers to the database of China scientific and technological core journals, and the Statistical Source Journal of China Scientific and Technological Papers published by China Institute of Scientific and Technological Information, also known as "China Scientific and Technological Core Journal". The subject category is mainly natural science, which is a relatively recognized source periodical catalogue of scientific and technological statistics in China at present.

The latest edition is the 20 19 edition, and the magazine Electrical Applications is a natural volume. Inquiring about the citation report of China sci-tech periodicals (core edition) and natural science volume (20 19 edition), the periodical was not found.

Therefore, this journal does not belong to the 20 19 edition of scientific and technological core journals. Before the database is updated in 2020, the journal does not belong to the core of science and technology.
