论文摘要
真相，一致性和基本等价都可以用游戏来表征，即所谓的评估游戏，模型存在游戏和Ehrenfeucht-Fraisse游戏。我们指出这些游戏的巨大亲和力彼此，并将这种现象称为逻辑中的战略平衡。特别是，我们将策略从一个游戏转换为另一个游戏。
Truth, consistency and elementary equivalence can all be characterised in terms of games, namely the so-called evaluation game, the model-existence game, and the Ehrenfeucht-Fraisse game. We point out the great affinity of these games to each other and call this phenomenon the strategic balance in logic. In particular, we give explicit translations of strategies from one game to another.
