Harmonic functions--the solutions of Laplace's equation--play a crucial role in many areas of mathematics, physics, and engineering. But learning about them is not always easy. At times the authors have agreed with Lord Kelvin and Peter Tait, who wrote ([18], Preface) There can be but one opinion as to the beauty and utility of this analysis of Laplace; but the manner in which it has been hitherto presented has seemed repulsive to the ablest mathematicians, and difficult to ordinary mathematical students.

很好的书哦。努力学习
需要的时候还是要常翻番的
比较容易看懂
都是为了考试而买！看着还行！
内容没有看，但觉得有点坑，原来就是本一般平装的书，纸质也有点差，竟然四十多，不过，也可能是书的内容很有价值吧，看过后再评论。
