命题

Drawing on the resource-based view of firm,this paper suggests that an inverted-U shaped relationship exists between market orientation and radical innovations,and offers a theoretic model that focuses on the curvilinearity of the moderating effect of market orientation on the entrepreneurial orientation-radical innovations ...

基于资源与能力理论，在企业家导向对突变创新正向影响的基本命题基础上，分析了不同水平市场导向对企业突变创新的倒U形影响关系，以及市场导向对企业家导向和突变创新间正向关系的倒U形调节作用。

Two normal forms, best-simple normal form and literal normal form, are presented at first in order to eliminate the complexity of formulas decision. Based on the two normal forms, a deduction proof of decidability theorem in L and a decision algorithm P based on deduction for proportional formulas are given and a decision machine found on P, DMBD, is also designed.

首先提出了消解复杂性的两种范式：最简范式和文字范式，在此基础上给出了L的可判性定理的演绎证明及命题公式的演绎判定算法P，并基于ML语言设计了基于P的演绎判定机DMBD。

Based on the two normal forms, the decidability theorem in L is then proved and a deduction-based decision algorithm P is designed. The time complexity O(n3) of P is much less than the complexity O(2n) of the true value table method and the complexity O(n5) of HAL based on the tactic scheme.

首先定义了消解复杂性的两种范式：最简范式和文字范式，在此基础上采用演绎方法证明了L中的可判定性定理，并设计了命题公式的演绎判定算法P。P的时间复杂度为O(n^3)，远远小于基于真值表法的O(2^n)和基于策略方案HAL的O(n^5)。

The study of lattice-valued propositional logic system based on lattice implication algebra.On the bases of previous study, by using the concepts and methods of T algebras we established the lattice-valued propositional logic system LP , whose truth values domain is a lattice implication algebra, and discussed systematically the semantical and syntactical properties of LP , proved the soundness theorem 、consistency theorem、deduction theorem and the decidability of validity of the system when the truth values lattice is finite. We also discussed the relationship between the α-theorem of some premise, say A, and the closed sets that contain A.

本文在前人研究工作的基础上，利用T代数的概念与方法，建立了真值取于格蕴涵代数的格值命题逻辑系统LP，对它的语义及语法性质进行了较系统的研究，得到了它的可靠性定理、协调性定理及演绎定理等，证明了值格有限时系统"有效性"的可判定性并讨论了某一前提A下的α定理与包含A的闭集之间的关系。
