对话当事人 Dialogue party

曾学过武术 劈砖为教学更直观 Have studied martial arts for the teaching split brick more intuitive

　　昨日，华西都市报记者联系上了川大计算机学院35岁的副教授魏骁勇。

yesterday,West China metropolis daily reporter contacted my computer college 35 years old, an associate professor of WeiXiaoYong.

　　谈起为什么要劈砖教学，魏老师特别澄清了自己并不是为了哗众取宠：“我只是为了教学更直观，并不是专门去劈砖的。”他说，因为这门课是“科学工程实践”，演示劈砖的过程是为了用这种方式引发学生学习这门课的兴趣，明白最简单的科学原理运用得当，也能产生意想不到的效果。

Talk about why want to split brick teaching,Miss wei special clarified themselves and not to try to please the public with claptrap:"I'm just in order to teaching more intuitive,And not just to split brick."He said,Because this course is"Science and engineering practice",Demo split brick process is to use this way to trigger students' learning interest in this course,Understand the most simple scientific principle is applied proper,Also can produce the result that expect is less than.

　　魏骁勇并不避讳自己会武术，他曾是绵阳少年业余武术队的队员，小时候也曾跟着电视劈过几次砖头，都成功了。不过他表示，劈砖成功是正确地运用了科学原理。

WeiXiaoYong is not afraid he would martial arts,He was mianyang young amateur wushu team players,When I was a child was also follow the TV splitting a few times bricks,All succeeded.But he said,Split brick success is the correct use of the scientific principle.

　　谈到这次意外出名，魏骁勇说有些小烦恼：“我很想知道是哪个同学上传的视频，关键是把学院搞错了。”他笑说，并不会责怪上传视频的学生。

When it comes to the accident famous,WeiXiaoYong said some small troubles:"I want to know is which students upload video,The key is the institute made a mistake."He said, laughing,Will not blame upload video students.

　　“我心里有点发毛，不晓得明天会有什么样的情况等着我。”魏骁勇对自己突然爆红于网络，还有些接受不了，“何况我大学逃学、教书劈砖这些事情，我父母都一直不是很清楚。这下全暴露了。”

"My heart a little beard hair,Don't know tomorrow will be what kind of situation waiting for me."WeiXiaoYong to oneself when it has a sudden flat red in network,Also some can not accept,"How much more I university play truant/Teaching split brick these things,My parents always is not very clear.This is all exposed."

劈砖原理冲量定理加杠杆原理 外加点小运气 Split brick principle impulse theorem and the lever principle some little luck

　　昨日，魏骁勇向记者详细讲解了劈砖过程中包含的科学原理：“其实就是科学运用于实践，再加上一些小小的运气。”

yesterday,WeiXiaoYong to reporter explains in detail the split brick process contains scientific principle:"In fact is scientific use in practice,Add a little luck."

　　魏老师解释，所谓的运气是指砖的硬度不同，劈砖时发出的力度不同，也许遇到一块烧制得较好的砖，可能就无法一次性成功。

Wei teacher explains,The so-called luck is refers to the brick of hardness is different,When the strength of split brick a different,Maybe meet a piece of fire better brick,They could not success at one time.

　　但如果掌握对了科学原理，正确实践，成功劈砖的几率很大。

But if the master to the scientific principle,Right practice,A good chance of success split brick.他说，其中主要包含两个科学原理，一个是冲量定理，一个是杠杆原理。首先要把砖头悬空，这样力不至于被桌面分散。根据冲量定理的公式，当人以很快速度并在很短时间内完成劈砖的动作，这就足以产生很大的力将砖头劈为两半。当砖头悬空部分更多时，事实上砖头与桌面的边缘形成了一个省力杠杆，当力作用于更省力的远端时，就会被放大。由此劈开砖头就更容易了。 He said,The major contains two scientific principle,One is the impulse theorem,One is the lever principle.First of all to put in a brick,This force should not be desktop dispersion.According to the impulse theorem formula,When a person with fast speed and in a very short time split brick action,It is enough to make a big force will brick split in two.When conducting more bricks impending part,In fact the brick and the edge of the desktop formed a effort lever,When work is more efficient for the far end when,Will be amplified.This split brick is more easy.

　　最后，魏老师也提醒，虽然科学原理的运用看似简单，但劈砖还是有一定风险的，希望观看了视频的网友不要模仿，以免受伤。

finally,Wei also remind the teacher,Although the use of scientific principles seem simple,But split brick or have a certain risk,Want to watch the video of the net friend don't imitate,In case of injury.

　　现场演示连试两次没成功 第三次砖才断 The demo even try twice failed third brick to break

　　昨晚，记者来到魏骁勇位于川大基础教学楼的实验室。在实验室最里面的墙角处，还堆放着7匹火砖。因为劈砖视频太火，昨日已有不少媒体找到他，在跟记者聊天时，魏骁勇就断断续续接了五六个电话。

Last night,The reporter comes to WeiXiaoYong based teaching building is located in my laboratory.In the laboratory in the corner,Still piled up with seven horse fire brick.Because split brick video too fire,Yesterday has quite a few media to find him,With reporters in chat,It has been WeiXiaoYong received five or six telephone.

　　“我可以再给你们演示一下。”可魏骁勇连试了两次都没成功，“呵呵，还需要一点运气。讲课之前我也是实验了两次的。”说着他脱掉外套，并在砖块上垫了一些纸巾。深吸两口气，1、2、3，嗨！砖块应声断成两截。

"I can give you a demonstration."Can WeiXiaoYong even tried twice he didn't succeed,"Ha ha,We need a little bit of luck.Lecture before, I also experiment for two times."And he took off his coat,And in the bricks pad some tissue.Deep suction two tone,1/2/3,hi!Bricks answered and broken into two pieces.

　　魏骁勇说，因为昨日劈砖太多，右手有些痛，影响了发挥，不过这也说明科学原理运用得当，即使手痛也能劈开砖，并非是靠蛮力成功。

WeiXiaoYong said,Because yesterday split brick too much,Right hand some pain,Affected play,But it also shows that scientific principle is applied proper,Even if the hand pain can also split tiles,By brute force is not successful.

　　学生说法 Students view

这老师真牛 还用太极讲科学 The teacher really cattle still use to tai chi tell science

　　如果你认为魏骁勇上课只有劈砖这一招，那就错了。魏骁勇目前带了8名研究生，他们时常被老师广泛的爱好和稀奇的教学方式“惊”到。

If you think WeiXiaoYong class only split brick this recruit,But it would be wrong to.WeiXiaoYong now took eight graduate student,They are often the teacher a wide range of hobbies and new teaching methods"surprised"to.

　　“我以为魏老师教我们打太极就已经够牛了，(没想到)现在还劈砖。”一位学生说，魏骁勇打了10年的太极拳，在香港读书和工作时就收了100多名太极拳学生。在川大，本系的学生和教授加起来，也有40多人跟魏骁勇学打太极拳。

"I thought wei teacher teach us tai chi had a cow,(Didn't expect)Now also split brick."One student said,WeiXiaoYong played in 10 years of tai chi chuan,In Hong Kong to read and work to accept more than 100 taijiquan students.In my,The department's students and professors up,Also has more than 40 WeiXiaoYong with learning to play taijiquan.

　　学生们还透露：“跟劈砖一样，在魏老师教太极拳的时候，也会讲一些跟我们的研究和课程相关的东西。”

The students also revealed:"Split brick with as,In wei teacher when tai chi chuan,Also can speak some with our research and curriculum related things."

大学学建筑 曾获老师特许逃课 College building was awarded the teacher franchise cut class

　　跟记者交流时，魏骁勇不像视频中那么“放得开”，双排扣的米色风衣扣得严严实实，虽然已是大学教师，但他大学本科时也曾逃课。

To the reporter when communication,WeiXiaoYong don't like video in so"Put to open",Double-breasted cream-colored wind solidly plastered over two,Though it is already university teachers,But his university degree also had cut class.

　　魏骁勇在昆明读大学，学建筑。可从大一开始就逃课，一直逃到班主任忍无可忍去找他。“班主任说，我只要把系里8个老师全部说服，就同意我不上课。”后来，魏骁勇真的带着预先做好的课题见了所有老师，并成功说服了他们。此后，一直到大学毕业魏骁勇都过着背着画板到处画画的潇洒日子。

WeiXiaoYong in kunming university of reading,Learn building.But from freshman year to cut class,Has fled to the teacher in charge unbearable to find him."Teacher in charge said,I just leave the department and a teacher all persuade,Will agree, I do not have classes."later,WeiXiaoYong really with the advance of the subject to see all the teacher,And successfully persuading them to.Since then,Have been to university graduate WeiXiaoYong were on the back of natural and unrestrained day painting sketchpad everywhere.

　　用自己的方式一直学得不错的魏骁勇，从学士、硕士一直读到香港城市大学的博士。直到2008年后，作为引进人才，进入四川大学计算机系任教。

In their own ways have been learn good WeiXiaoYong,From a bachelor's/Master has been read, city university of Hong Kong to the doctor.Until 2008 years later,As the introduction of talents,Enter sichuan university computer teaching system.

课堂考勤 他研究人脸识别系统 Classroom attendance he studied face recognition system

　　因为上课从来不点名，魏骁勇曾遭到学生的“抗议”，“从不缺席的学生说我不点名，对他们不公平。”

Because the class never call the roll,WeiXiaoYong was under attack by the students"protest","Never absent students say I don't call the roll,For they do not fair."

　　因为觉得一堂课要花很多时间点完100来个名字很麻烦 ，魏骁勇研究出“基于人脸识别的考勤系统”，他上课前将教室全景拍下，回去用识别系统对照所有学生的面部。没有显现的就是没有来上课的。“所以我的课，出勤率很高。而且其他系也开始在用系统打考勤了。”魏骁勇说。

Because think lesson to spend a lot of time point over 100 to a name very troublesome ,WeiXiaoYong developed"Based on face recognition of check on work attendance system",He the classroom before class panoramic filmed,Go back to use recognition system control all the students' face.No revealed is didn't come to class."So my class,Attendance rate is very high.And other system also began in system play a check on work attendance."WeiXiaoYong said.

　　单掌断砖的秘密 在于砖的一头翘起一点 Single palm broken brick secret is brick of a head tilted a little

方法A Method A砖块全部放在桌面上。这样，手劈向砖块时的冲力，通过砖块形成压力扩散到桌面上，力量分散，不易劈断。

All brick on the table.this,Hand split toward bricks of impulse,Through the bricks formation pressure diffusion to the table,Scattered forces,Split off not easily.

方法B Method B砖块的一端留在桌面，另一端伸出桌面。这样，手劈向砖块时行成"剪力"，把砖块折断，不过这需要很大的力量，一般常人很难做到。

One end of the bricks in desktop,The other side out of the desktop.this,Hand to make bricks split into"shear",The broken bricks,But it takes a lot of strength,General ordinary people difficult to do.

方法C Method C将砖块的一端放在桌面上，用手按住，另一端伸出桌面，并抬起来一点点。 手劈向砖块时，力量用在砖块抬起的顶部，在最短的时间内以最快的速度劈向砖块。

Will at the end of the bricks on the table,Put my hand on,The other side out of the desktop,And up a little bit. Hand to split the bricks,Power in the top of the lift with bricks,In the shortest time with the fastest speed to split toward bricks.

　　{1}劈末端

{1}Cleft end

　　根据杠杆原理，手掌击在砖块最末端，会产生最大的冲击力。

According to the lever principle,Palm struck the bricks the end,Will produce the maximum impact force.

　　{2}微翘起

{2}Micro tilt

　　根据冲量原理，砖块要跟桌面有一定距离，这样才能产生更大的力。
