来自主题: _Auto_Fans版 - Coolant漏了,有图片,请高手指点
1999 Audi A4,coolant漏了一地。
第一张图,打开hood检查reservor和hose,从上方看不出什么裂缝。
第二张图,从车底下看,有一根hose从engine前方进去,可能是连到radiator去的。被
挡住了,看不见里面,可能radiator位于风扇和engine之间。
第三张图,从reservor往里面注水,车底下哗哗的漏,水都从engine和oil filter
holder之间的间隙流下来。黑色的罐子是oil filter.
第四张图,如果盖上reservor的盖子,哗哗漏的水流立刻变成一滴一滴的漏。
毛病大吗?漏的是hose还是radiator? radiator有没有坏?mechanics说要把车开来做
一个pressure test才能确定radiator漏没漏,在决定拖不拖车之前,有没有什么简单
办法知道radiator漏没漏?

来自主题: Automobile版 - Re: 急问各位大侠客
这原因可多了。
你加coolant的时候有没有先对百分之五十的水
搅和好了再加到radiator里面呢?因为纯的coolant
导热性能很差所以需要借水的帮助。当然如果要
要让引擎迅速冷却的话用纯水是最好的啦。但是
为了防止 radiator生锈或是冻坏至少要和入百分之
四十以上的coolant。和入的coolant要是超过百分之
七十以上引擎就可能会overheat。还有你有没有定期
用些化学物质来flush radiator?要是radiator里面某些
地方堵住了也可能导致overheat。 
也有可能你车子的给radiator降温的风扇坏了,那就得修。

公孙兄这就稍微有点外行了。
楼主确实是犯了个错误,他以为trans fluid是流经radiator来冷却的。事实上
transmission的冷却和发动机冷却是一个道理,都是通过冷却液来流经发动机里的冷却
室或者transmission里面的冷却通道。不同的是发动机发热量大,因此水箱也比较大。
transmission的冷却液也有个小radiator,比如宝马就是这个小radiator和大radiator
连在一起,通过大radiator来给trans fluid冷却,但两种制冷剂是分开的两个不同的
循环通道。
所以说楼主拔那个所谓的hose是多此一举,即使拔开,里面也只有冷却液而没有
transmission fluid。
另外老车尽量不要换trans fluid了,如果以前一直是定期换,那还行。如果好几万
mile或者好几年没换过,那是自己找死。
80%老车长期没换过trans fluid的车,换后车就报废。

2. 启动发动机,关闭制冷,打开空调加热档最大温度和最大风,偶尔加点油门到4000

3. 约10分钟后,测radiator的inlet管子温度约195F,outlet管子温度95F,加coolant

练习了一阵子.
卖到临头,发现RADIATOR有漏.这也是在意料之中的事情. GERDO家的东西,大概都有点"

有一天我们在商量卖了换个大点的车,结果第二天水泵就坏了,说不得,修了之后又开了
三四年才卖掉.BTW,那车卖的时候十一万迈了,没有空调,但是外观显得巨新,12岁那年在
佛罗里达一个闷热的地方卖了一千一.

My career as a Cold Case Detective was built on being evidentially certain
about the suspects I brought to trial. There are times when my certainty was
established and confirmed by the cumulative and diverse nature of the
evidence. Let me give you an example. It’s great when a witness sees the
crime and identifies the suspect, but it’s even better if we have DNA
evidence placing the suspect at the scene. If the b... 阅读全帖

http://www.reuters.com/article/2013/05/15/us-cancer-chemo-idUSB
(Reuters) - After decades of using one-size-fits-all therapies to combat
cancer, doctors are using new tools to help decide when their patients can
skip chemotherapy or other harsh treatments.
An approach to oncology that has been in place for decades is beginning to
yield to an arsenal of long-term clinical studies, genetic tests and novel
drugs that target cancer cells and their infrastructure.

厄。。我来科普一下
背景辐射一般在2mSv/a (Sv=sievert=joule/kg),期中包括宇宙背景辐射,自然界矿石
中的放射性元素(uranium),以及被人体摄入的放射性元素(Rn/K)。
在美国,radiation protection的dose limit是严格控制的。对于occupational
radiation worker是50mSv/a。对于public是1mSv/a
lz说的研究x-ray,具体实验条件,防护措施如何?
实验室有常备GM counter吗?实验室和x-ray machine有shielding吗?进出要佩戴film
badge吗?还有,进实验室前要不要进行操作培训?
如果对实验室的危害不是很确定的,最好的办法应该是找老板谈谈。或者,去学校的
radiation safety office。一般来说,学校既然有x-ray source,就一定有RSO,而且
老板也应该是authorized licensee。
其实radiation是满有趣的,有radiation therapy和diagnostic radiology。没有像大
家想的这么恐

A uniformly charged spherical ballon deflates suddenly,maintaining

which of the following statements concerning the possible emission
of electromagnetic radiation during this process is true?
(a) Radiation is emitted because charge is accelerated.
(b) Radiation is emitted because the surface density of charge increases
(c) No Radiation is emitted because there are no magnetic fields present.
(d) No radiation is emitted because charge is conserved.
(e) No rad

来自主题: Science版 - Re: 大牛们给个解释
electric dipole radiation是因为Hamiltonian中的p*E项,
magnetic dipole radiation是因为角动量和磁场的相互作用.
两个应该能够同时发生, 但对于一般的物质, electric dipole radiation
要比magnetic dipole radiation强10^5, 所以一般只有在electric dipole
radiation是forbidden的时候才考虑magnetic dipole, 同时也要考虑
electric quadrupole了. 磁性材料就不清楚了.

Radiation exceeds limits at Ibaraki facility
A University of Tokyo facility in Ibaraki Prefecture, north of Tokyo, has
reported radiation levels higher than legal standards.
The facility alerted the central government on Tuesday after it registered 5
microsieverts per hour before 8:00 AM and the radiation level continued to
exceed the yardstick figure designated by a law for 10 straight minutes.
The facility is located in Tokai village, about 110 kilometers south of th... 阅读全帖
