Application and practicality are the characteristics of this textbook. While introducing the theory of the subject in a simple way, we should pay attention to integrating theory with practice. Combining with many years of research projects, teachers will introduce a large number of typical cases, which focus on related fields in students’ daily learning and living. Each principle is equipped with a case, each chapter has a typical case to explain the contents. At the end of the book, there is a chapter to introduce the five typical cases, which link the theories of the textbook.
