1·The greatest lower bound of constraint was the bound of tasks for satisfying the constraint and can be used to guarantee the "meet row" weakly hard real-time constraint.
下确界限制用于保证任务满足“至少满足”弱硬实时限制，是任务满足限制的下确界。
2·In this paper, some important properties of cone lower bound and the greatest cone lower bound are introduced, the corresponding proofs are presented.
讨论了锥下界和锥最大下界的若干重要性质，并给出了相应的证明。
