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。

On the poet's choice, mainly be decided by two standards, one is the popularity and influences of works; two is the meaning of the creations development that it create for the whole colony. Owing to above two standards, the writer chooses seven writers to launch the treatise, they are Jidi Maja, Jimu Langge, Luwu Laqi, Ma Deqing, Aku Wuwu , Asu Yuer, Eni-Mushashijia. In discussing the process, the writer used the nationality and Poetics of the poem as the latent clues, emphasized to inquiry into three main roads and three main realms. On the article structure, the full text mainly is divided into two parts, one is the concrete imago analysis to each poet creations, two is upon the analytical foundation the integration of the theories, with this the treatise could be united into an organic whole. In regard to the conclusion, we educe the characteristics of the colony is deep consciousness to the nation culture, also extensive exploration and attention to poetics. The blemish is the inside emotion and sensibility is similar or duplicate and that the creation pattern is narrow. The main develop threads of the colony are upon the female clan culture the diverse poem skill investigation, its nation culture value tropism present the rising spiral type of return- leave- return again.

在研究方法上，本文以意象分析法为贯穿全文的主要方法，通过对意象的具体分析来透视凉山诗群的诗歌世界；在诗人的选择上以其作品的影响力及意义为标准，选择了这一诗群的七位诗人展开论述，他们分别是吉狄马加、吉木狼格、倮伍拉且、马德清、阿库乌雾、阿苏越尔、俄尼·牧莎斯加；在论述过程上，笔者以诗歌的民族性和诗性作为前后贯穿的潜在线索，着重探讨了这一诗群创作的三个主要倾向和三个主要领域，前者详论，后者略述，具体表现在对前三位诗人的论述以诗人论的形式详细展开，探讨他们所代表的凉山诗群发展过程中的三个主要创作倾向，即民族文化的深层开掘、诗艺的实验性探索和艺术哲学的尝试性建构，对后四位诗人的论述则以主题的方式展开，探讨他们所代表的凉山诗群在爱情诗、乡土诗和文化诗三个领域的探索；在文章结构上，全文主要分为两大板块，一是对各位诗人创作的具体意象分析，二是在前文分析的基础上进行理论的整合，以此将前面散珠似的论述贯穿成一个有机整体；在结论上，我们通过整合得出：1、凉山诗人群新时期以来诗歌创作的大致发展脉络：在母族文化的基质之上的多元诗艺探索，其民族文化价值取向呈现为回归—离去—再回归的螺旋式上升形态；2、新时期彝族凉山诗人群汉语诗歌创作的特点，即民族文化意识的深层自觉，对诗性的关注和探索；3、新时期彝族凉山诗人群汉语诗歌创作的缺陷，即情感意蕴的雷同和创作格局的狭小。
