Sorry that I can't type Chinese. I need to measure the IR spectrum of H2O2
vapor. Based on literature data, I should get at least 5% H2O2 in water
vapor at room temperature if I use the 50% H2O2 water solution. However, i
almost didn't get it at all. Any suggestion? Is it due to the stabilizer
added (commercial)?

Engine灯亮很久了,去检查,说是Vapor canister system坏掉了,要从toyota dealer
那里order整套系统然后换上,估计要大几百刀。
问了一个朋友,说这个东西可以在网上自己买,然后找人自己换(当然不是去修车行了
,去那种自己在家修车的地方),问题就是换这个需要把整个车都顶起来,但是换起来
不是很费劲,全套下来估计小几百刀的样子。穷人一个啊,能省点就省点吧。。
想问问版上有了解这个canister system的人不?去哪种网站可以自己买的?另外顺便
求提供自己在家修车的师傅的联系方式。。

It IS the condensation of vapor/sweat from your body.
Your body is warmer than the environment and the water vapor saturation
point near your body is higher that the environment. The environment is
colder than your body, therefore, has a lower saturation point. When the
relative humidity is high outside (like what you experienced in Hawaii),
with a vapor barrier (waterproof/breathable membrane), the water vapor
condenses at the interface, which is the inside of your jacket.

【开发故事】引言:20世纪的伟大发明——高亮度蓝色发光二极管
2010/03/29 00:00
高亮度蓝色发光二极管之父:中村修二
20世纪90年代中期使得超过人类身高的超大屏幕全彩显示器成为可能、2000年前后
又为手机屏幕彩色化做出贡献的,就是高亮度蓝色发光二极管。蓝色发光二极管技术还
成为了开发蓝色激光器的基础,其实用化使得录制高清节目的蓝光成为现实。高亮度蓝
色LED通过与红色和绿色LED组合便可制造出各种颜色,接踵而来的便是促生出取代白炽
灯和荧光灯的新一代节能照明巨大市场。
日本的企业及大学为开发高亮度蓝色LED做出了巨大贡献。在GaN LED的研究阶段,
名古屋大学赤崎勇教授(现为名城大学特聘教授)领导的研究小组取得了出色的成果。
在之后的实用化及高亮度化阶段,日亚化学工业的中村修二(现为美国加州大学圣塔芭
芭拉分校教授)发挥了重要作用。1995年1~3月《日经电子》连续报道了中村从GaN类
蓝色LED的研究开始到产品化为止的故事,此次本站将刊登该系列报道,希望能向读者
展现在该技术开发过程中,技术人员的艰辛与快乐。
