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。

Based on the radar dense data of convectional cloud on June 12,2004 in Yongdeng county,choosing two similar convectional clouds as seeding and non-seeding cloud,the remarkable changes of radar echo parameters of the seeding cloud compared with the non-seeding cloud were discussed in this paper,and the rain enhancement effect was evaluated primarily with ground observational rainfall data.The results show that many aspects of the seeding cloud,such as precipitation,life characteristic and vertical characteri...

利用2004年6月12日甘肃省永登县雷达观测对流云的加密资料，选取了2次相似对流云过程分别作为目标云和对比云，探讨了目标云作业前后较对比云雷达回波有关参数的显著变化，并结合地面雨量点观测资料对地面人工增雨作业效果进行了初步分析，结果表明：目标云在降水、生命期特征、回波垂直特征参数变化方面，表现出作业前后较对比云存在明显差异，目标云作业40 m in后地面产生0.6 mm降水，而对比云则从新生发展到减弱消散阶段经历较短的时间(30 m in)，地面并无降水产生，从而推断本次人工增雨达到了一定的预计效果。

It was found that the relationship between the nonsmooth appearance of leaf surface and its wettability is very strong, and the shape and distribution of the non-smooth elements are the decisive factors. The surface with regular distribution of convex elements presents large contact angle, strong water repellence, and good self-clearing ability, and that of hairy non-smooth elements takes the nextplace.

Based on the flaw of the probability reliability model in the case of small amount of information,non-probability and mixed probability/non-probability reliability models are presented. When the uncertainty of the basic random variable is described by convex, analytical and numerical methods are constructed to calculate the convex of response variable. The infinite norm index, which is the minimal infinite norm distance from original coordinate point to the surface of the limit state in the standard interval space, is presented to measure the safety of the structure.

The core problem of load forecasting is technical matters or the mathematical model. Conventional model is described by clear mathematic representation, which has the advantages of little calculation and high speed, but which has lots of limitations such as non-self learning, and non-self adapting at the same time.

传统的数学模型是用显示的数学表达式加以描述，具有计算量小、速度快的优点，但同时也存在很多的缺陷和局限性，比如不具备自学习、自适应能力、预测系统的鲁棒性没有保障等。

The simulation results also verify that the algorithm exhibits corking robustness against the external interference and modeling errors. Ideal control effect can be achieved without changes of the algorithm and its parameters in time-delay system, non-minimum phase system, unstable object, non-linear system and MIMO system. It is so that why this algorithm has generality and is easy to use, which is favorable for the application and generalization of predictive control.
