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 下方往上 Sample flow ││ ││ ││ ││ ││ ││ Quartz ││ ││ tube ││ ││ ││ ↖│ ││ │↖ ││ ││ Argon tengential flow ││ ││ ↑ Sample 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 -- ╔══ ║ ● ╠══ ╔═ ║ ╠═ ║ ║ ╚══ ║ ║ ╚═ --
