如果想深入了解度量空间、拓扑空间、紧集、一致连续、映射、算子、测度等建立在现代ZF集合公理基础上的概念，请参看下册，本书可作为实变、复变、泛函、场论、数学物理方程、概率论、微分几何前置课程，扩展性相当强。(If you want to understand the metric space, topological space, compact, uniform continuity, mapping, operator, measure set up on the basis of the modern concept of axiom ZF, please refer to the book, this book can be used as a real variable, complex, functional, field theory, mathematical physics equations, probability theory, differential geometry, pre course, expansion very strong.)
