为了凑免运买多了一台加热器。还没有开封。卖30刀。UTC pick up.

产品描述:
Product Description
The Kenmore 72085 oil-filled heater can save you money on your heating bill
by adding warmth to the room you’re using, so you can turn down the
household heat. As the oil inside the sealed heater heats up, it gently and
quietly warms a room up to 150 square feet. Because the heater is sealed,
you never have to refill the oil.

"Dangerous levels of radiation are not expected to reach Washington,"
Secretary of Health Mary Selecky said in a news release. "The tragic events
in Japan don't pose a radiation exposure risk to people in our state. And we
urge people not to take potassium iodide or iodine pills; it's unnecessary
and could be harmful to some people."

来自主题: Running版 - solar radiation and running performance
Recently i was looking at solar radiation data in local weather history, i
found out that besides temperature and humidity, when solar radiation goes
beyond 200watts/m^2, my running performance becomes affected, my HR will
start to climb up a few bpm every mile under the same pace. 70F with
overcast weather is noticeably better than 70F under 200watts/m^2 or more.
In a sunny summer day here, SR will go up to 200watts/m^2 around 7:30AM, up
to 900watts/m^2 at noon. In a sunny winter day here, SR w

Small amounts of radiation headed for California, but no health risk seen
Very low levels of radioactive isotopes from the damaged Japanese nuclear
plant are expected to reach California as soon as Friday, but experts say
the amount will be well within safe limits. A network of radiation monitors
is keeping close watch.

来自主题: EnglishChat版 - Ribbon Radiator
My "electrical stove" in the kitchen was out of order two days ago and
i need to report this to the rental office and ask them to send
some one to fix it. However, i don't know how to say it in english.
Therefore I studied the English to Chinese Dictionary for a long
, find the following descriptions that match my needs well:
range and ribbon radiator.
So i called and told the lady with confidence that the ribbon radiator
on the range did not work. The poor lady could not get what i mean
by it:)

March 15, 2002 | Mars Odyssey, the latest orbiter to start mapping the red
planet, is back to full working order. Its cameras have always worked fine,
but last August controllers lost communication with Odyssey's Mars Radiation
Environment Experiment (MARIE) while the craft was still en route to Mars.
The broken component — designed to measure the radiation danger that future
travelers to Mars might encounter — was largely ignored until the craft

1) I don't know. There is no solid data about cell phone radiation's
physiologic affect.
2) I don't know either.
I guess the simple experiment is to give cultured cell line radiation (mimic
those of cell phone) for months or longer and see any effect. I guess some
people did it but did not find anything interesting.
epi is not the only thing we can look at, but currently epi data is the data
we can have. No mechanistic research. On the other hand, for smoking,

MM这话说的很伤人啊。本来Radiation Oncology 就需要team work, 医院里哪里不是呢
?不能光看收入吧,这也太肤浅了。
如果MM仍然对Medical Physics 感兴趣的话,需要一些Medical/Radiation的知识。如
果以前没有接触过这一行,需要在RO做Postdoc先熟悉起来吧。

本来几乎已经决定做radiation therapy 方向的了,因为知道北美这个方向的职位多些。
但是刚刚看到首页上GE上海招工程师,X-ray 成像方面也在招人,渴望回国的想法一下
占了上风,而且,imaging 或image processing 是我这么多年来一直想做却不曾有机
会做的方向(其实以前对这个方向也不了解,只是看到 present image 的时候很炫,
不像1-D siganl 或数据处理那样枯燥乏味)。
而且最近学了点MRI和CT成像的皮毛觉得确实有意思。
刚才搜了搜,找不到国内这方面需求的具体分析,不知道国内对radiation therapy 还
是imaging的需求大(我不介意去医院还是去公司做研发)。 如果国内imaging 方面需
求也蛮大,就想做这个方向了。
有熟悉这些领域的同学么?多谢了!

你是刚读phd,选方向?看你说"imaging 或image processing 是我这么多年来一直想做
却不曾有机会做的方向",听着感觉你已经至少phd毕业了....个人感觉国内的医院没啥
研发吧?而且国内学校里研究MRI的都很少.radiation therapy相对imaging对数学要求
低了不少,而且很多学习imaging的同时还要学不少EE的东西.如果考虑赚钱,单讲北美的
话,radiation therapy和MRI的工资,都作为medical physcist的话差别不大,不过还是
要再次提醒下,medical physicist的board考试问题......

谢谢回答。
我是刚读了2个学期,现在要选方向。
不过以前有过一些其他经验。
要是回国做研发,应该还是在GE,西门子等这样的公司吧。刚刚看到主页上说GE要找x线
成像的senior engineer.
回国要是去医院,想来待遇还不如外企。
北美我倒是知道作为medical physicst, radiation therapy 比diagnostic imaging 的工作机会多
很多,而且北美医院的待遇高。
但从个人兴趣来说,我倒还是觉得imaging 更challenging & interesting。我很喜欢
傅立叶变换或者重建算法之类的东东。 Radiotherapy 真的好boring,数学上更是"
embarrassingly simple"(用我们老师的话说). 如果选radiation therapy,纯粹是因
为在北美更好找工作,在医院里。考board 倒是有思想准备,老师们天天在耳边吹这个。

来自主题: Automobile版 - radiator fan和空调的关系
高压端过高一般是通路阻塞造成的, radiator fan如果转速不够的话, 是可能引起这
个问题的, 不过500块换个风扇貌似多了点, 你倒是可以充r134a以后用个台扇吹,
看看有没有改进
造成高压端压力不正常的还可能是冷凝器内部阻塞, 不过你用了一个星期, 貌似不像
存134a的瓶子阻塞, 高压管阻塞, 膨胀阀阻塞, 膨胀阀阻塞一般是因为回路中有水
蒸汽, 就是你换压缩机的时候没有抽真空, 在膨胀阀结成了冰。 这个如果有问题就

Here is my suggestion based on your photo.
It looks like the O-ring is wider.
1) use a wire hanger to hook the fitting so it won't drop in the radiator.
2) use a plier to pull out the O-ring out.
3) you should be able to pull 50% of the fitting up with the wire hanger.
4) you are on your own because I am not sure if there is enough fitting
for you to pull it with with a plier or do you have anything L shape tool
that is strong enough to pull it up
