  Solid modeling is a technique underlying CAD software as we see it today, and
its theories and algorithms are among the most fundamental milestones in the
historical development of CAD. Basically, it has answered the question of what
geometric information a computer should store and how to store/manipulate them
in order for the computer to aid the processes of design and manufacturing.
This paper provides a brief review (in Chinese) on the historical development
of solid modeling, its fundamental research problems, as well as their
challenges and state of the art. It then concludes with three prospective
trends of solid modeling, especially the promising paradigm shift from
"Computer-Aided Design" to "Computer-Automated Design".
