标题[情报] 材料分析二三事
时间Wed Dec 14 12:18:22 2011
1. 期中考分数会在12/14 14:00之後公布在系办外 老师有加分过
如果对分数有问题的同学 可以到旧物理馆305或是224找我
2. 我今天发现讲义上有些部分变成乱码
可能是我从老师那边复制档案的时候出了问题 因为我有的电子档也是乱码
----------------------------------------------------
Lecture 9 第11张投影片右半部 不清楚的部分 文字内容如下
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张投影片

3. 有同学反映当天没拿到分组报告的题目
我就po在下面
专题报告(分数比重15%)
请从下列物件中选择一样进行材料分析。
请各组将其想法、考量、采用分析技术、以及预
期分析结果撰写成一份报告书。(可选择之分析技术与可探讨之材料性质不受任何限制,
必要时可采用一些假设。)
(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) 阿基师的菜刀 (好像跟一般的不锈钢菜刀不太一样)
(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
注意事项:
˙报告中请不要垄长地描诉所采用分析技术之原理与仪器。
如有摘用其他作者之文章词
句或研究成果,请记得加注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. 有什麽问题再跟我联络
