1. 期中考分數會在12/14 14:00之後公布在系辦外 老師有加分過
如果對分數有問題的同學 可以到舊物理館305或是224找我
2. 我今天發現講義上有些部分變成亂碼
可能是我從老師那邊複製檔案的時候出了問題 因為我有的電子檔也是亂碼
----------------------------------------------------
Lecture 9 第11張投影片右半部 不清楚的部分 文字內容如下
Samples
- Almost any liquid, solid or gaseous sample
- Microliter volumes or microgram masses
- Aqueous samples can be analyzed directly
- Complex solutions
˙ Diluted
˙ Solvent extraction
- Solids can be dissolved//digested
Analysis time
- Sample prepararion (0 sec to 24 hr)
- Analysis after calibration (10 - 120 sec.)
Limitations
- No information on chemical form of metal
- Sample prep. can be tedious
- Limited to metals/metalliods
- Destructive
第18張投影片
裝置 Quartz tube 右下方輸入 Argon tengential flow

3. 有同學反映當天沒拿到分組報告的題目
我就po在下面
專題報告(分數比重15%)
請從下列物件中選擇一樣進行材料分析。請各組將其想法、考量、採用分析技術、以及預
期分析結果撰寫成一份報告書。(可選擇之分析技術與可探討之材料性質不受任何限制，
必要時可採用一些假設。)
(1) A multilayered (nylon/ionomer/polyethylene) plastic bag, which has a
tendency to fail at the nylon-ionomer interface
(2) A fluid-like material that seems to change its viscosity upon the
application of electric field
(3) A piece of glass material that is able to block the sun’s infrared rays
(4) 阿基師的菜刀 (好像跟一般的不鏽鋼菜刀不太一樣)
(5) A bolted joint from the collapsed ceiling of an indoor swimming pool.
(6) A MLCC capacitor, whose dielectric loss is increased gradually with
operating time
(7) A white light LED, whose light color is becoming bluer with operating time
注意事項:
˙報告中請不要壟長地描訴所採用分析技術之原理與儀器。如有摘用其他作者之文章詞
句或研究成果，請記得加註References。
˙All team members must put their signatures on the cover page of the report
to confirm his/her contributions to the report.
˙Due date: Wednesday of last course week.
4. 有什麼問題再跟我聯絡
