GE回复如何正确使用微波炉
(2007-06-05 11:39:59)
我把文章分成两个部分，欢迎对英文感兴趣的朋友来翻译——虽然这是一篇和科学有关系的文章但却很容易懂，所以你们都来试一试好吗？
翻译的时候注明是红色部分或绿色部分，我会挑选翻译得又快又好的朋友送出《中国绅士》或是《中国淑女》作为感谢，你们自己挑要哪一本好吧。
是不是不是很难？大家翻译得都很好，而且这么踊跃！谢谢翻译，多学一种语言就是多了一双看世界的眼睛。对吗？如果你们想要参加赠书的话，记得下次要用sina的名字。
现在我已经放了1+2段翻译好的在这里，这样可以作对照来看了。现代的电器设备并不可怕，但我们需要更多一点的安全常识。请多多告诉你的朋友。
还要告诉我你们要绅士/淑女哪一本。

A 26-year old man decided to have
a cup of coffee. He took a cup of
water and put it in the microwave
to heat it up (something that he had
done numerous times before). I am
not sure how long he set the timer
for, but he wanted to bring the
water to a boil. When the timer shut
the oven off, he removed the cup
from the oven. As he looked into the
cup, he noted that the water was
not boiling, but suddenly the water
in the cup "blew up" into his
face. The cup remained intact until he
threw it out of his hand, but all
the water had flown out into his
face due to the build up of
energy. His whole face is blistered and he
has 1st and 2nd degree burns to
his face which may leave scarring.
He also may have lost partial
sight in his left eye. While at the
hospital, the doctor who was
attending to him stated that this is a
fairly common occurrence and water
(alone) should never be heated in a
microwave oven. If water is heated
in this manner, something should be
placed in the cup to diffuse the
energy such as a wooden stir stick,
tea bag, etc., (nothing
metal).
It is however a much safer choice
to boil the water in a tea kettle.

Electric's Response:
Thanks for contacting us, I will
be happy to assist you. The e-mail
that you received is correct.
Microwaved water and other liquids do
not always bubble when they reach
the boiling point. They can actually
get superheated and not bubble at
all. The superheated liquid will
bubble up out of the cup when it
is moved or when something like a
spoon or tea bag is put into
it.
To prevent this from happening and
causing injury, do not heat
any
liquid for more than two
minutes per cup. After heating, let the
cup
stand in the microwave for
thirty seconds before moving it or
adding
anything into
it.
Here is what our local science
teacher had to say on the matter:
"Thanks for the microwave warning.
I have seen this happen before. It
is caused by a phenomenon known as
super heating. It can occur anytime
water is heated and will
particularly occur if the vessel that the
water is heated in is new, or when
heating a small amount of water
(less than half a
cup).
What happens is that the water
heats faster than the vapor bubbles can
form. If the cup is very new then
it is unlikely to have small surface
scratches inside it that provide a
place for the bubbles to form. As
the bubbles cannot form and
release some of the heat has built up, the
liquid does not boil, and the
liquid continues to heat up well past
its boiling
point.
What then usually happens is that
the liquid is bumped or jarred,
which is just enough of a shock to
cause the bubbles to rapidly form
and expel the hot liquid. The
rapid formation of bubbles is also why a
carbonated beverage spews when
opened after having been shaken."
If you pass this on you could very
well save someone from a lot of
pain and
suffering.,
