In this paper, the bump patterns for flip-chip packages are discussed first, then an experiment is setup to study the dispensing phenomena for different bump patterns, and the CAE software is used to analyze and identify with experiment mutually. From these thorough comparisons and analytical analysis, the existence of channel could slow down the flow, the high density of bump could speed up the flow, and it could avoid the air trap by modified the bump and channel's arrangement on flip-chip package. Then flows in rectangular microchannels driven by capillary force and gravity are discussed; furthermore, the theoretical model of flow in microchannel driven by capillary force and gravity is formulated from the Navier-Stokes equations.

本文首先针对覆晶底部充填进行相关理论推导、实验与模拟，探讨不同凸块配置模型所造成的波前不平滑现象对底部充填流动的影响；即依据相关参数建立模型进行底部充填实验，同时以CAE(Computer-Aided Engineering)模流分析软体进行模拟，在完成理论探讨、实验与模拟分析之后，交叉比较理论、实验与模拟分析结果，归纳出影响底胶充填流动之因素，由结果显示在凸块密集度较高的区域，凸块可以帮助流动，但是在凸块区后方的沟槽区域则因为凸块区所提供之流量不足，所以会造成波前落后的现象，另外藉由修改凸块与沟槽配置的关系，可以有效的控制波前形状的变化情形，避免产生包风现象。

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。

When the edges of a convex polygon are traversed along one direction, the interior of the convex polygon is always on the same side of these edges, a new algorithm for computing the convex hull of a simple polygon is proposed first, which is then extended to a new algorithm for computing the convex hull of a planar point set.

本文依据凸多边形的这一特性，提出求解简单多边形凸包的新算法，进而扩展得到求解平面点集凸包的新算法。新点集凸包算法先找到点集的极值点，得到极值点间的候选点子集，再求得相邻极值点间的有序凸包点列，最后顺序连接极值点间的有序凸包点列，得到凸包。

Feng Zhengjie has created a series of female portraits since 2001. These female figures are wearing green eye shadow, red lip stick, fashionable clothes and their hairs are burning like red flares. Here, one of his Chinese Portrait series is such a painting. The girl in the painting is pretty and sexy, while her eyes tell us that she is deeply lost in her unhealthy lifestyle.

俸正杰基本上都是以红色和绿色构成画面的主要色彩，人物塑造有脸谱化的特征：猩红的嘴唇、精心修剪的眉毛、细小迷离的眼珠等等，再加上同样猩红的背景和人为的光晕，使作品在视觉上有一种明显地向外凸的感觉，无论你接不接受，它会一下子跳到你的面前。
