Through a discussion on the suffix features of miniterm and maxiterm ,this paper offers a suffix calculating approach to miniterm and maxiterm in principal disjunctive normal form,principal conjunctive normal form determined by disjunctive normal form,and conjunctive normal form of propositional formula.

通过极小项和极大项的下标特征的讨论，给出了由命题公式的析取范式、合取范式而确定的主析取范式、主合取范式中的极小项、极大项的下标计算方法，从而简化了由繁杂的命题公式推演或真值计算求主范式的计算过程。

Furthermore, the first-order optimality condition and its equivalent reformulations for generalized semi-infinite max-min programming with a non-compact set are presented using the lower-Hadamard directional derivative and subdifferential.2. Chapter 3 studies the gradient-type methods for unconstrained optimization problems. Section 1 proposes a new class of three-term memory gradient methods. The global convergence property of the method is established. Furthermore, in order to improve the convergence property of the method, a new class of memory gradient projection methods is presented with the property that the whole sequence of iterates converges to a solution to the problem under the conditions such as pseudo-convexity and continuous differentiability of objective function. In section 2, two new classes of methods, called gradient-type method with perturbations and hybrid projection method with perturbations, are proposed. In these methods, non-monotone line search technique is employed, which makes them easily executed in computer.

第3章研究了无约束优化问题的梯度型算法，第1节提出了一类新的三项记忆梯度算法，讨论了算法的全局收敛性，进一步提出了一类新的具有更好收敛性质的记忆梯度投影算法，并证明了该算法在函数伪凸的情况下具有整体收敛性，第2节在非单调步长搜索下提出了带扰动项的梯度型算法及其混合投影算法，这两类算法的一个重要特征就是步长采用线搜索确定而不象许多文献中那样要求步长趋于零，这样更容易在计算机上实现，在较弱的条件下证明了这些算法的全局收敛性，数值算例表明了算法的有效性。

The second and contrasting part of such a ''.

Source term for plant decommission is defined and the importance of the source term in plant decommission plan is described in this paper.

本文论述了退役源项在核设施退役中的重要性，定义了什么是退役源项。

Startup Delayer's claim to fame isn't that it helps you easily remove applications from your startup routine—it does that, but that's old hat for startup managers. The value of Startup Delayer is its ability to delay and stagger the launching of startup apps.

Startup Delayer 的与众不同之处不在于它帮你从启动例项中轻松地删除应用程序-那是旧式的启动项管理器， Startup Delayer 的价值是延迟和交错程序的启动时间。

Yet the "Desiderata" which Shore found among his papers may indicate that Jones had planned to spend additional time on linguistics: the third desideratum is "A Grammar of the Sanscrit Language, from Panini, etc."; the fourth,"A Dictionary of the Sanscrit Language, from thirty-two original Vocabularies and Niructi."

然而绍尔在他的文件中找到的 Desiderata或许暗示出琼斯本来计划在语言学上花费更多的时间：其中的第三项迫切需要获得之物是，"梵语语法，帕尼尼等"；第四项是，"梵语词典， from thirty-two Vocabularies and Niructi "。
