对模糊命题演算的形式演绎系统中的公理L10:(A→B)∨((A→B)→A∨B)进行了较为深刻的研究,一方面应用L10讨论了L^*系统与Lukasiewicz系统,GSdel系统的相互独立性,说明L10是L^*系统区别于其它模糊命题演算的形式演译系统的特征标志,另一方面应用L10证明了L^*系统中的条件演绎定理,给出了L10在L^*中的一个重要应用。
We studied the axiom L10 in the formal deductive system L^* for fuzzy propositional calculus. At the first. Through utilizing axiom L10, we investigated independences of the system L^*, Lukasiewicz system, and the Goedel system. This show that axiom L10 is a character mark of the system L^*; At the second, we proved the conditional deduction theorem in the system L^* by employing axiom L10. In this may, we made an important application of axiom L10 in the system L^*.
