设计理论是组合数学的一个重要分支，本书是根据作者在南开大学组合中心为研究生讲课的讲义，润色、补充而成，是一本设计理论的引论性书籍，涵盖最基本的古典设计理论。内容包括：Symmetric BIBDs、Resolvable BIBDs、Orthogonal Latin Squares等。

本书适合组合数学、计算机科学等相关专业的学生和教师使用参考。

This book deals with the basic subjects of design theory.It begins with balanced incomplete block designs，various constructions of which are described in ample detail.In particular，finite projective and affine planes,difference sets and Hadamard matrices，as tools to construct balanced incomplete block designs，are included.Orthogonal latin squares are also treated in detail.Zhu's simpler proof of the falsity of Euler's conjecture is included.The construction of some classes of balanced incomplete block designs，such as Steiner triple systems and Kirkman triple systems，are also given.

T-designs and partially balanced incomplete block designs (together with association schemes)，as generalizations of balanced incomplete block designs，are included.Some coding theory related to Steiner triple systems are clearly explained.

The book is written in a lucid style and is algebraic in nature.It can be used as a text or a reference book for graduate students and researchers in combinatorics and applied mathematics.It is also suitable for self-study.
