Saturday afternoon, I and classmates do the little test of the report since attrition together in the classroom, can you become a success? Let our wait and see what happens.
周六下午，我和同学们在教室里一起做摩擦起电的小实验，能不能做成功呢？让我们拭目以待吧。
We need to prepare a plastic rule before the experiment, bits of a few shredded paper. Everybody was taken out thin thin napkin begins " treatment " , want to turn it into wastepaper. See some classmates are incompact only ripped slow rise, some is very anxious it is a pepperbox, took out scissors unexpectedly, "Ca of Ka Ca Ka " cut quickly rise, return some to hold paper together, "Clang " , in the time that the paper of a piece of when everything is all right is blinking " have one's body smashed to pieces " , look I am agape, the wastepaper caboodle that everybody prepares resembles together " snow mountain " , the wastepaper that counts me makes an appointment with more than 50!
实验前我们需要准备一把塑料尺，一些碎纸屑。大家拿出了薄薄的餐巾纸开始“加工”，要把它变成纸屑。只见有的同学不紧不慢地撕了起来，有的很着急是个急性子，竟拿出了剪刀，“咔嚓咔嚓”快速剪了起来，还有的把纸捏在一起，“哗”的一下，一张好端端的纸在一眨眼的时间里就“粉身碎骨”了，看得我目瞪口呆，大家准备的纸屑堆在一起像一座“雪山”，数一数我的纸屑约五十多片呢！
The experiment began, want a rule to grind heat to stand by small wastepaper again above all, the response that sees small wastepaper how? Everybody ground of too impatient to wait takes rule, some is chafing in the apace on the head, some wild on the dress land are chafing, return some to put rule in the emphatically in control to chafing, everybody resembles extremely scientist, doing a test wholeheartedly, wait for me to chafe rule heated, when standing by small wastepaper, interesting phenomenon happened, small wastepaper had reaction, shook to rise dancing! I slowly rule drive up when, small wastepaper changed sit-ups unexpectedly, go up too amused, but my parity sees wastepaper does not have any reaction, get scratch one's head urgently, turning all round like the ants on a hot pan, how to return a responsibility? The reason that I consider the scrip that may be her is too big! My parity sees wastepaper does not have any reaction, get scratch one's head urgently, turning all round like the ants on a hot pan, how to return a responsibility? The reason that I consider the scrip that may be her is too big! I tell her to rip the scrip again a bit smaller, she tried to rise again, this meeting wastepaper jumps to rule not to agree to come down unexpectedly, seem to regard rule as " " , also do not see it falls down a long time, parity cries gladly rise, "Result of my experimental make it! " at this moment the classmate all round lets me feel very comical, on some arm, wastepaper was stained with on the body, breathing out madly to be sucked! Be sucked! Some hairs also became roost head, return some to staring at rule to suck the wastepaper since to become cross-eye quickly, the classroom ased if to become a lab really.
实验开始了，首先要把尺子磨热再去靠近小纸屑，看看小纸屑的反应如何？大家都迫不及待地拿起尺子，有的在头上快速地摩擦着，有的在衣服上疯狂地摩擦着，还有的将尺子放在手心里用力地摩擦着，大家像极了科学家，正在专心致志地做着实验，等我把尺子摩擦变热了，靠近小纸屑时，有趣的现象发生了，小纸屑有了反应，摇晃了起来在跳舞呢！我慢慢把尺子抬高时，小纸屑竟换成了仰卧起坐，一上一下太好玩了，可我的同位见纸屑没有任何反应，急得抓耳挠腮，像热锅上的蚂蚁正在团团转，怎么回事？我想可能是她的纸片太大的缘故吧！我的同位见纸屑没有任何反应，急得抓耳挠腮，像热锅上的蚂蚁正在团团转，怎么回事？我想可能是她的纸片太大的缘故吧！我便告诉她把纸片再撕小一点，她再次试了起来，这会纸屑竟跳到尺子上不肯下来，好像把尺子当成“家”了，半天也不见它落下来，同位高兴地喊起来，“我的实验做成功了！”这时周围的同学让我感到很好笑，有的袖子上、身上沾满了纸屑，狂呼着吸起来了！吸起来了！有的头发也成了鸟窝头，还有的盯着尺子吸起的纸屑都快成斗鸡眼了，教室仿佛真的变成了实验室。
The rule that why grinds heat can suck a wastepaper? Because attrition rule can produce electrostatic phenomenon, electrostatic attraction can be sucked at the weight of wastepaper greatly, if electrostatic attraction is less than the weight of wastepaper, suck naturally do not rise!
为什么磨热的尺子会吸起纸屑呢？因为摩擦尺子会产生静电现象，静电的吸力大于纸屑的重量就能吸起来，如果静电的吸力小于纸屑的重量，自然就吸不起来喽！
This issued us to understand attrition has electric principle, this small experiment but really interesting!
这下我们都明白了摩擦起电的原理，这个小实验可真有趣呀！
