  1. In addition, i have done some following works : to compile usual chemistry english words ( basic concepts and basic theory ), to translate chemical experiment for students of senior one, to translate exercises for students of senior one, to accumulate and compile about twenty parts of bilingual teaching material, to design about ten classes of teaching material, to issue my article in an important magazine of our contoury, to take part in the chemistry bilingual teaching study group of shanghai, etc. through bilingual teaching, the students have made progress in following aspects : ( 1 ) they have enlarged science vocabulary obviously, and feel easy to accept them ; ( 2 ) they have read some science material more fluently, and their ability has risen in inquiring from internet ; ( 3 ) they can express, in english, some usual chemical terminology, chemical principle, substance phenomenon and experiment procedures ; ( 4 ) in both chemistry and english, they have certain confidence to study well, and have made great progress in both subjects comparing with students of no bilingual teaching

    在兩年的論文撰寫過程，本人在自編教材進行化學雙語教學實踐和研究的同時，還編寫了化學雙語常用詞匯（基本概念、基本理論部分） 、翻譯了高一化學學生實驗、翻譯了高一上學期學生練習冊習題、收集和編寫了雙語教學內容和閱讀材料20篇左右、雙語教學設計十篇、在國家核心期刊《中小學英語教學與研究》上發表文章： 《高中化學雙語教學的體會》 、在市化學中心組-雙語課題組中，參與編寫了化學雙語教師用書、等等。學生通過雙語教學，主要獲得了以下收獲: （ 1 ）科技詞匯量明顯的增加，對科技詞匯的接受己不一再感到困難; （ 2 ）能較熟練的閱讀有關科技文章，同時，提高了網_ _上查詢科技資料的能力; （ 3 ）對簡單常用的化學術語、化學原理、物質現象和實驗操作過程等，能用英語表達下來; （ 4 ）對學好英語和化學都有了一定的信心，在英語和化學兩門學科的學習_ l ，比非雙語學生平均有了明顯提高。
  2. At the same time, the writer also analyzed four problems that teaching material exits : first, a chemistry experiment is placed down and depended on the theory and is in subsidiary position ; and is short of expanding the space ; second, chemistry the experiment arrangements in order changed again and again, lacked complete science theory to guide ; third, there are fewer chemistry experiment ; fourth, there are more verification experiments, fewer investigating experiments

    同時，筆者也分析了教材存在的四個問題：一是化學實驗處于依附理論的附屬地位，拓展空間不足；二是化學實驗編排存在反復性，缺乏完整科學的理論進行指導；三是化學實驗數量偏少；四是驗證實驗偏多，探究實驗偏少。
  3. Firstly, this thesis was based on thoughts and theories of chemistry teaching material experiment parts of establishments that was discussed, and stressed on studying the united states reformation of the high school chemistry teaching material practices since half a century ; and summed up five characteristics on experiment parts of establishments : first has more than hours of the experiment lesson, and student need use half time do the experiment ; second is to emphasize strict and careful science attitude, and educate students as scientists to do the experiment ; third is that a chemistry experiment should face to the society, face to the life and face to the other related course ; fourth is that investigating types and its ability have been used as the important contents on chemistry experiment reform and development ; fifth is that chemistry teaching material establishment emphasize universal science and technique knowledge, and increase citizens chemistry science attainments

    本文首先在論述化學教材實驗部分編制的思想理論基礎上，重點探討美國半個世紀以來中學化學教材的改革實踐，並總結出了其實驗部分編寫的五個特點：一是實驗課時較多，學生需用一半的學習時間做實驗；二是強調嚴謹的科學態度，教育學生象科學家那樣去做實驗；三是化學實驗面向社會、面向生活、面向其它相關學科；四是探究式學習和探究式能力培養一直作為化學及化學實驗改革和發展的重要內容；五是化學教材編制強調普及科學技術知識，提高公民的化學科學素養。
  4. A recommend for basic organic chemistry experiment in university - the production of acetyl - salicylic ( aspirin ), which takes the salicylic acid and acetic oxidecon as raw material under the atmospheric pressure condition, takes the strong sulfuric acid as catalysis, through acetoxylation, heating, dialysising, filtering, heavy crystallization, the white solid product can be made finally

    摘要推薦一個大學基礎有機化學實驗乙酰水楊酸（阿斯匹林）的制備，即在常壓條件下以水楊酸和乙酸酐為原料，在濃硫酸為催化劑下通過酰基化試劑酯化反應，經加熱、析濾、重結晶，最後得白色固體產品。
  5. 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。
