量子力学 郑海荣 编 mobi 下载 fb2 夸克云 azw3 网盘 pdf pmlz

Basic principles and theory required for developing a practical and intuitive understanding of quantum mechanics are exarnined. Animations , conceptual problems and practical applications are presented at the end of each chapter to help readers better visualize and understand quantum phenomena As the book is especially designed for bilingual teaching and learning , the characteristics of differences between eastern and western thought and presentations are considered with attempts to bridge those differences. The target audience is undergraduate students majoring in physics and other areas for which a basic knowledge of quantum mechanics is expected.
