Our approach is based on an extended relational calculus, and reduces the consistency problem to a satisfiability problem of relational formulae.
该方法以扩展的关系逻辑为语义基础，把一致性问题归结为关系逻辑公式的可满足性问题。
When the domain of interpretation is finite and its size is a fixed positive integer, the satisfiability problem in the first-order logic can be reduced to SAT.
当解释的论域是一个固定大小的有限集合时，一阶逻辑公式的可满足性问题可以等价地归约为SAT 问题。
