I from small was full of to aerospace yearning, the dream is worn one day oneself can fly on aerospace, go probing cosmic mystery. We welcomed an extraordinary opportunity today -- 3 13 astronaut give divine boat us brought another subject of the test in sky.
我自小就对太空充满了向往，梦想着有一天自己能够飞上太空，去探索宇宙的奥秘。今天我们就迎来了一个特别的机会——神舟十三号的三位宇航员给我们带来了一堂别样的空中实验课。
In numerous experiment, letting what I feel the most magical is experiment of water oil depart, mr. Wang Yaping is all smiles a small bottle was held in the hand, she tells us: The maize liquid that float wears above is oily, ad cool-headed transparent liquid is water below. Mr. Wang Yaping shakes emphatic of this small bottle at the same time ah shake, still sold at the same time close child, let us guess what can produce next. When she stops the action in the helper, magical one act happened, water and oil move dye like us same, bit by bit lump! Meanwhile, tellurian students did similar test according to the teacher's method, the result mixes however in aerospace disparate: After shaking momently, a lot of small bleb appeared in bottle, but oil and water do not have method lump at all.
众多实验中，让我感到最神奇的就是水油分离实验了，王亚平老师笑容满面的在手中握了一个小瓶子，她告诉我们：上面浮着的黄色液体是油，下面沉着的透明液体是水。王亚平老师一边将这个小瓶子用力的摇呀摇，一边还卖了个关子，让我们猜一猜接下来会发生什么。当她停下手里的动作时，神奇的一幕发生了，水和油就像我们调颜料一样，一点一点的混在一起了！与此同时，地球上的学生们按照老师的方法做了同样的实验，结果却和太空中截然不同：在短暂的摇晃之后，瓶子里冒出了许多小气泡，但是油和水根本没办法混在一起。
This moment, is Mr. Wang Yaping smiling to cast again gave another issue -- how to come to water and oily departure in aerospace? At this moment, a spacefarer Mr. Xie Guangfu sets an example to us rise, see he covers the ribbon above small bottle on the hand only, the circle turns like carrying it to resemble playing yo-yo next, had done not have a little while, water and oil are mixed on the earth same, fat surplus was in on bottle half part, water sank below bottle half part. Mr. Xie Guangfu tells us, this is the principle that used centrifugal.
这个时候，王亚平老师又微笑着抛出了另一个问题——在太空中怎么将水和油分开来呢？这时，另外一名航天员叶光富老师便给我们示范起来，只见他把小瓶子上面的带子套在手上，然后拎着它像玩溜溜球一样转圈圈，没过一会儿，水和油就和地球上一样，油浮在了瓶子上半部分，水沉到了瓶子下半部分。叶光富老师告诉我们，这是利用了离心机的原理。
Did not think of a simple test accumulate contained so deep scientific sense, space test is really wonderful!
没想到简简单单的一个实验就蕴含了这么深的科学道理，太空实验真奇妙啊！
