有效性

Personally, I believe that the pure new-media and new-technique experiment has become the exclusive privilege of Western artists. The criteria of modern Chinese art are always the effectiveness of revolt and the inherent constructiveness.

我以为单纯的新媒介新技术实验，其实已是西方艺术家的特权，至于中国当代的艺术，其标准永远是反叛的有效性和内在建设性。

Whether a teaching research scheme is efficient largely depends upon such aspects as the pertinency of the research theme and form, the extent to which the participants are involved in the research process, the constructiveness to resolve practice problems, the continuity and progressiveness of the research theme, the attention to generation in the research process and the compatibility of theory with practice.

观察分析教研活动有效性，关键要看：研究主题与形式的针对性；活动过程的可参与性；解决实际问题的建设性；研究主题的连续性与渐进性；关注过程的生成性；理论结合实践的指导性等。

This chapter mainly takes NBP of CSPC as a sample, through the establishment of training evaluation model to establish the direct contact of training effectiveness transformation and staff performance, and improved the training system and training effectiveness transformation, enhanced the employee performance significantly, validated the effectiveness of training evaluation model.

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。
