„The surface of water has the tensity, will make the waterdrop stay in the coin surface. But the hand soap drips into the waterdrop, destroyed the water-drop surface tensity, lost the tensity fetter the waterdrop naturally to scatter in all directions to open, flows on the table.” “水的表面存在张力,才会让水滴停留在硬币表面。而洗手液滴入水滴里,破坏了水滴表面的张力,失去张力束缚的水滴自然四散而开,流到了桌上。” Big Liu spoke the principle of water surface tensity, wants to verify with the experiment, making people very easy to understand. 大刘将水面张力的原理讲出来,和实验想印证,让人很容易就能听懂。 After he said that looks to Yang Yuping. 他说完之后,看向杨宇平。 Yang Yuping nods, making him prepare the second experiment, then before returning to the teacher's desk , to continue to teach: 杨宇平点了点头,让他去准备第二个实验,然后回到讲桌前,继续讲课: „ A moment ago we through the experiment of coin and waterdrop, proved truly has Strength, making the waterdrop stay on the coin. “刚才我们通过硬币和水滴的实验,证明了确实存在一种力量,让水滴停留在了硬币上。 „, Possibly had the schoolmate to ask, this was Strength useful? Moreover this Strength looks not strong. “那么,可能就有同学要问了,这种力量有什么用呢？而且这种力量看上去一点都不强。 „Then, we use another experiment again, told everyone, the water surface tensity was useful.” “接下来,我们再用另一个实验,告诉大家,水面张力有什么用。” Finishing speaking. 话音刚落。 Big Liu and another science and technology education lift a transparent water jar of rectangle, starts to get ready to test. 大刘和另外一名科教将一个长方形的透明水缸抬上来,开始准备实验。 „First, we use the paper to fold a paper boat, attractiveness that which schoolmate paper boat folds? Helps?” Yang Yuping takes up a A4 paper, prepares to give the first row of student. “首先,我们用纸叠一架纸船,哪个同学纸船叠的好看？帮个忙好吗？”杨宇平拿起一张A4纸,准备递给第一排的学生。 Eve looks at all around in an instant secretly, then deeply inspires, raises hand saying: „I fold, I have not been controlled today, I guaranteed.” 伊芙转眼偷瞄四周,然后深吸一口气,举手道:“我来叠,我今天没有被控制,我保证。” This saying said that also caused surrounding schoolmate's one to laugh. 这话说出来,又引起周围同学的一阵哄笑。 Before Yang Yuping, heard, this little miss because was been sad by the matter of Alienized Human Spirit control, therefore hands over the paper, kind saying with a smile: „Naturally, I heard that you are very usually lively, if you do not raise hand on own initiative, instead like controlled.” 杨宇平之前也听说,这个小姑娘因为被异化人精神控制的事情而难过,于是把纸递过去,和蔼的笑道:“当然,我听说你平时很活泼,你要是不主动举手,反而像被控制了。” This saying caused laughing. 这话又引起了哄笑。 Eve somewhat shy received the A4 paper, folding that starts to toss about, folded a crescent moon ship to hand over finally: „Like this Ok?” 伊芙有些腼腆的接过A4纸,开始翻来覆去的叠,最后叠了一架月牙船递回去:“这样可以吗？” „So long as it can float.” “只要它能浮起来。” Yang Yuping received the paper boat, puts in the rectangular transparent water jar. 杨宇平接过纸船,放到长方形透明水缸里。 On the paper boat static float water surface, the indoor does not have the wind, therefore does not have the wind to move the paper boat. 纸船静静的漂浮水面上,室内没有风,所以也没有风吹动纸船。 „Paper boat floats on the water surface, without the power, will not naturally move, now we will drop drop of hand soap in the rear area of paper boat, will have a look to have anything.” Yang Yuping was saying then takes up that bottle of hand soaps on table, the drop in the rear water of paper boat. “纸船漂浮在水面上,没有动力,自然也不会动,现在我们将在纸船的后方滴一滴洗手液,看看会发生什么。”杨宇平说着便拿起桌上的那瓶洗手液,滴在纸船的后方的水里。 The hand soap enters the water, the paper boat looked like moved the strong motive force suddenly, the rapid traverse, has hit another head of rectangular water jar forward. 洗手液入水,纸船就像是突然活动了强劲动力,向前快速移动,一直撞到长方形水缸的另一头。 This rectangular transparent water jar is 1.5 meters, the paper boat walked 1.5 meters distance, hit another of water jar to stop. 这个长方形透明水缸长有1.5米,纸船就足足走了1.5米的距离,撞到了水缸的另一头才停下。 In Military Scientific Research Class, some students looked dull. 军事科研班中,有一部分学生都看呆了。 Before seeing this experiment, cannot imagine completely, drop of hand soap really has such big might. 在看到这个实验之前,完全想象不到,一滴洗手液竟然有这么大的威力。 In Yang Yuping is raising hand the hand soap, said: „ Drop of hand soap, made the paper boat move 1.5 meters distance. What principle is this? 杨宇平举着手里的洗手液,说道:“一滴洗手液,就让纸船移动了1.5米的距离。这是什么原理？ „, Is the hand soap what strong power raw material? The answer obviously is not. “难道说,洗手液是什么强劲的动力原料吗？答案显然不是。 „ Draws Strength that the paper boat moves, actually water surface tensity. “拉动纸船移动的力量,其实还是水面的张力。 „ Pays attention to my word usage, is ‚drawing’, rather than ‚promotion’, among this has the subtle difference. “注意我的用词,是‘拉动’,而不是‘推动’,这之间有着微妙的差别。 „ In the experiment of coin and waterdrop, we had shown, the surface of water has the tensity, but the hand soap can destroy the water surface the tensity. “在硬币和水滴的实验中,我们已经证明,水的表面存在张力,而洗手液可以破坏水面的张力。 „ Similarly, in the paper boat experiment, the hand soap destroyed the paper boat rear water surface tensity, but the paper boat front water surface tensity draws the paper boat forward, until water jar end. “同样的,在纸船实验中,洗手液破坏了纸船后方的水面张力,而纸船前方的水面张力就将纸船向前拉动,直到水缸尽头。 „If fellow schoolmates can promote the experiment of paper boat to be interested to the water surface tensity, can attempt in a broader lake surface, sticks a scrap soap behind the paper boat, believes can walk is farther.” “如果各位同学对水面张力可以推动纸船的实验还有兴趣,可以尝试在更宽广的湖面上,在纸船后方粘一小块肥皂,相信能走的更远。” Completes two experiments, the Military Scientific Research Class student is all attracted by this class content. 做完两个实验,军事科研班的学生全都被这节课的内容所吸引。 The water, is everyone side most common thing, what Strength but few people will observe the water surface to have. 水,是所有人身边最常见的东西,但是很少有人会去观察水面存在着什么样的力量。 Yang Yuping, turned the printed lecture on table to the next page, then said: „ Ok, we through two experiments, proved existence of water surface tensity, as well as lets the method that the paper boat moves through the water surface tensity. 杨宇平顿了顿,将桌上的讲义翻到下一页,接着说道:“好了,我们通过两个实验,证明了水面张力的存在,以及通过水面张力让纸船移动的方法。 Does the class that „ that this and we must teach today what relations have? “那么,这和我们今天要讲的课有什么关系呢？ „ Before beginning lecturing, I have mentioned a word, ‚space tensity’. “在开讲之前,我提到过一个词,‘空间张力’。 „ Supposition, the space is like the water, has a tensity. “假设,空间和水一样,都存在着一种张力。 „, Can we use this tensity, making our ‚paper boat’ also move? For example Code Shenzhou anything.” “那么,我们有没有可能利用这种张力,让我们的‘纸船’也动起来？比如神舟号什么的。” Niu Dazhi raises hand immediately, said: „I know, sticks a soap on the Code Shenzhou buttocks.” 牛大志立即举手,道:“我知道,在神舟号屁股上面粘一块肥皂。” „Your really was too intelligent.” Fang Yuan several people cannot bear turn head take to look askance he. “你真特么是太聪明了。”方源几人忍不住回头拿眼斜他。 Yang Yuping to such teasing, not only has not been angry, instead cheerful saying: „Right, if we can discover existence of space tensity, and affects it, sticks together soap on the buttocks of Code Shenzhou ‚’, then Code Shenzhou really soap ’ will someday fly because of this ‚.” 杨宇平对这样的调侃,非但没有生气,反而乐呵呵的说道:“没错,如果我们能够发现空间张力的存在,并且去影响它,在神舟号的屁股上粘一块‘肥皂’,那么说不定有一天神舟号真的会因为这块‘肥皂’而飞起来。” After having cracked a joke, Yang Yuping goes back in the topic the knowledge: „Then the issue came, what is the space tensity?” 开过玩笑之后,杨宇平又将话题拉回到知识上:“那么问题来了,什么是空间张力？” He has a look at the people, seeing this group of students is the eye gleaming is listening earnestly, then continued: „ Everyone in the school, should get up the astrophysics, has certain understanding of the origin of universe. 他看看众人,见这群学生都是眼睛亮闪闪的在认真听,便继续说下去:“大家在学校的时候,应该都上过天体物理学,对宇宙的起源有一定的了解。 „ According to description on textbook, universe about 13.7 billion years ago a large explosion of forms. “根据课本上的描述,宇宙是由大约137亿年前发生的一次大爆炸形成的。 „ Moreover, universe also in unceasing expansion. In other words, the universe most starts is a point, after having the large explosion, unceasing expansion. “而且,宇宙还在不断的扩大。换而言之,宇宙最开始是一个点,发生大爆炸后不断的扩大。 „ We imagine, the unceasing expansion of universe like a ball, then the universe space is smooth? “我们想象一下,宇宙像一个球一样不断的扩大,那么宇宙的空间是平坦的吗？ „ Before is very early, Human thought that the ground is even, but Earth is in fact round. “在很早之前,人类觉得地面是平的,但事实上地球是圆的。 „ Universe is formed by a large explosion, moreover in the unceasing expansion, it can be imagined, the universe space is not smooth, but has the curve. “宇宙是由一次大爆炸形成的,而且还在不断的扩大,可想而知,宇宙的空间也不是平坦的,而是有弧度的。 „ Since there is a curve to exist, then the space is not fixed, but can twist and change. “既然有弧度存在,那么空间就不是固定的,而是可以扭曲、变化的。 „ In other words, the space has the tensity, if we can affect this tensity, eliminates the spaceship rear tensity, then the front tensity like the water surface tensity, will draw our spaceships is walking forward. “也就是说,空间存在着张力,如果我们能够影响到这种张力,消除掉飞船后方的张力,那么前方的张力就会像水面张力一样,将我们的飞船拉着向前走。 „ This drive type, has another name, is called Curvature Driven, is the space and time level science and technology. “这种驱动方式,有另外一个名字,叫做曲率驱动,是时空层面的科技。 „According to the civilized differentiating grade, this science and technology has far exceeded the category of star civilization, is much higher than the Strong Interaction Force material.” “按照文明等级划分,这种科技已经远远超出了恒星文明的范畴,比强相互作用力材料还要高得多。” Fang Yuan hears here, finally understands that mysterious pulling force that „Lightning God Speed” has how comes. 方源听到这里,终于明白“闪电神速”产生的那种神奇的拉力是怎么来的了。 However, Yang Yuping supplemented one later: „ But, so far, we have not tested to confirm existence of space tensity. 不过,杨宇平随后又补充了一句:“不过,到目前为止,我们还没有实验能够验证空间张力的存在。 „Perhaps fortunately, on Fang Yuan had had the space tensity phenomenon, waits to go to war, must tie up the laboratory to study him well.” “幸运的是,方源身上或许已经出现了空间张力现象,等打完仗,得把他绑到实验室好好研究一番。” The people listened, starts to be laughing and playing. 众人听了,又开始嬉笑。 Han Youwei also turns the head, said low voice: „You definitely are the white mouse that the professor most loves.” 韩幼薇还转过头来,小声说道:“你肯定是教授最爱的小白鼠。”
