The feasibility and efficiency of analyzing concurrent programs mostly relies on the programs' representations. So modeling concurrent programs in a proper and suitable way is very important. Protected objects, which have been introduced in Ada95, are of significant importance in concurrent programming language. In this paper, process algebra is used to model Ada95 protected objects in a neat and tidy way. Because using process algebra can simplify process composition and conveniently hide internal details, it becomes easy to analyze Ada concurrent programs with protected objects and to combat problems of state explosion. In addition, many mechanisms similar to protected objects can be modeled in this way. With these models, many analyses, such as model checking, can be performed.
