汤川先生的这两本著作是在物资匮乏的情况下印制的,所以纸的质量很不好。然而书却是高质量的,既不失其理论性的物理内容,又省略了许多烦琐的数学公式,是两本简朴、流畅的好书,堪称名作。当然,作为读者,书中使我颇感费劲的地方还很多。 Mr. Yukawa’s two books were printed in the absence of materials, so the quality of the paper is very poor. However, the book is of high quality, not only losing its theoretical physical content, but also omitting many cumbersome mathematical formulas. It is a simple, smooth and good book that can be called a masterpiece. Of course, as readers, there are still many places in the book that make me quite strenuous.
