  3. In this paper, we take high molecule physics and the damage theory of rheologic material with lacuna as the basic, make the experiment as a mostly measure, take the pmma as a research object, to study the pmma ' s nonlinear viscoelasticity of high polymer. the technique showing minute details in minute view measure is used by the author to observe the change of crazing damage density follow the change of stress, time and temperature in term of creep and flab

    本文以高分子物理學、含缺陷流變性物體的材料破壞理論為基礎，以實驗為手段，以工程中常用的pmma為研究對象，對pmma銀紋破壞的非線性力學行為進行了研究。作者採用顯微技術，對pmma在蠕變或鬆弛條件下，不同應力水平和不同基溫下的pmma銀紋損傷進行了實驗研究。
  4. Zhang liji ( material physics and chemistry ) directed by professor xie xiaoming this paper is intended to solve problems for those who are designing, using pbgas. failure mechanism, as well as cycles to failure of two groups of pbga samples ( with / without underfill ) for thermal cycling conditions in the range of - 40 ~ 125, were presented. the experiment shows that solder ball in the samples without underfill cracked after 500 times cycle, no crack was found in the underfilled samples even after 2700 cycles

    通過一系列的實驗，得到以下實驗結果： ?在本論文設定的溫度循環條件下，未充膠pbga樣品的熱疲勞品壽命在500周左右，充膠樣品的焊點壽命高於2700周； ?對于未充膠器件，中心距（ dnp ）是決定焊點應力、應變大小的最主要因素，裂紋總是從中心距較大處萌生並向中心處擴展； ?溫度循環的過程中焊盤附近焊料組織明顯粗化。
  5. In order to satisfy the requirement of knowledge economy epoch and reform of current common physics experiment teaching in university, we can introduce some experiments about the new material zno : al studied in this paper into the electromagnetic researching experiments, such as hall measurements of semiconductor material in room and different temperature
