Color deterioration card? 变色卡？ Three-dimensional diffraction grating picture? 立体光栅画？ What the following students first think was that childhood, played one type to be able in the different angles, saw the different pictures the card toys. 下面的学生们第一想到的是那种小时候,玩过一种可以在不同角度,看见不同画面的卡片玩具。 However the quick this suspicion was overthrown, the typeface on that crowbar, at all is not the plane. But spuddings in the crowbar forcefully, can see the trace that gets down hollowly clearly. 但是很快这个猜想就被推翻了,那根铁尺上的字体,根本不是平面的。而是硬生生凿入铁尺之中,可以清楚看见凹陷下去的痕迹。 „Friendship... For All Time” Professor Kobayashi Sei look, in firewood of helpless combustion like raging fire. “友…谊之久”小林井教授的眼神,就像烈火中无助燃烧的柴薪。 Looks at does not have any anomaly directly, can see the typeface from a different angle. 正面看没有任何异常,换一个角度就能看见字体。 What did this indicate? 这说明什么？ Explained that the four characters on that crowbar, cast aside press down firmly during the portrays, is the level that is inconceivable has is vertical. 说明那根铁尺上的四个字,一撇一捺刻画之间,是难以想象出的水平垂直。 Its principle explained that is very simple, if a paper of thin as cicada wing, the side level is vertical in the vision, then it is very easy to vanish does not see. 它的原理解释起来很简单,如果一张薄如蝉翼的纸,侧面水平垂直于目光之间,那么它就很容易消失不见。 Similarly, bottom of typeface that on the crowbar gets down hollowly, so long as maintains the similar roughness with the surface. Side processing leaves to precisely letting the person terrifying straight line, can achieve such effect. 同样,铁尺上凹陷下去的字体底部,只要和表面保持同样的糙度。侧面加工出精确到让人恐怖的直线,就可以达到这样的效果。 Explained simply, but did to be difficult. 解释起来简单,但是做起来非常难。 Among live broadcasts, after having mechanical expert popular science of knowing the business, the students brush 666 in barrage as if by prior agreement crazily...... 直播间内,经过有懂行的机械达人科普后,学生们不约而同地在弹幕里狂刷六六六…… „hā hā just that side Japan Technologies, but also stated categorically that what/anything does not have, finally changes an angle by face-smacking.” “哈哈刚刚日理工那边,还一口咬定什么都没有,结果换个角度就被打脸。” „Was too crisp, to/clashes this visual effect, can that nut being inferior. They are not the thread cannot see, but the thread and silk are equally thin. But our these four characters, and mahjong is equally big, the difficulty naturally also wants on high many.” “太爽了,就冲这视觉效果,就能把那颗螺母给比下去。它们不是螺纹看不见么,可螺纹跟蚕丝一样细。而我们的这四个字,跟麻将一样大,难度自然也要高上许多。” „Only by doing so, this schoolmate?” Kobayashi Sei loose a few words, let barrage and following students are suddenly peaceful. “只有这样么,这位同学？”小林井松了的一句话,让弹幕和下面的学生们陡然安静。 „Very good mentality, lets processing precision that the person admires.” “很棒的思路,让人敬佩的加工精度。” „But in our opinion, this wins the gift, representative industrial level, missed a point from topest technique of manufacture.” “但是在我们看来,这见礼物,所代表的工业水平,距离最顶尖的制造技术还差了一点。” It is not arrogant, the technology that this crowbar shows, Professor Kobayashi Sei, borrows well-known high precision instrument Factory, similarly can make. 不是自大,这根铁尺所展现出的技术,小林井教授,借用国内知名的高精仪器工厂,同样可以制造出来。 The difficulty has certainly, the expenditure time will be a lot , may be unable to baffle him. 难度当然有,花费时间会很多,可难不倒他。 „Ended ended, looked at this fellow self-confident appearance, probably they can also cause carving characters of this mysterious effect.” “完了完了,看这家伙自信的样子,好像他们也可以弄出这种神奇效果的刻字。” „After all their precise processing technology World First, cannot stump them, is excusable.” “毕竟他们精密加工技术世界第一,难不住他们,也情有可原。” „Oh, although has not perplexed, but is not loses.” “唉虽然没有难住,但也不算输。” Among live broadcasts, also resumed the discussion. 直播间内,又恢复了讨论。 „Professor Kobayashi Sei, I think that you misunderstood my meaning.” Ye Qing raised in Yang hand the crowbar, transferred the other aspect. “小林井教授,我想你们误会了我的意思。”叶青扬了杨手中铁尺,将另一面转了过来。 „Initially you, bestowed a nut, making our processing have a screw.” “当初贵方,赠送了一颗螺母,让我们加工出一颗螺丝。” „We naturally want the exchange of gifts between friends, bestows one to need our two school cooperation, is the complete commemorating gift.” “那我们自然要投桃报李,赠送一件需要我们两校共同合作,才算完整的纪念礼物。” Stopped, Ye Qing is very that satisfied the expression opposite that fellows admit defeat. 停顿了一下,叶青很满意对面那帮家伙吃瘪的表情。 Demonstrates in the different angles the crowbar, confirmed that the reverse side of crowbar, after does not have any Chinese character, the Ye Qing vision is unflustered: „Friendship For All Time, is we give the blessing of your school.” 将铁尺在不同角度展示一遍,确认铁尺的反面,没有任何汉字之后,叶青目光从容不迫:“友谊之久,是我们送给贵校的一句祝福。” „I want to invite your school, in the reverse side of this crowbar, with your languages, engraves other few words, verifies our friendship.” “我想请贵校,在这根铁尺的反面,用你们的语言,刻上另外一句话,来鉴证我们的友谊。” „Carves a few words?” Kobayashi Sei some have not responded: „What words carves?” “刻一句话？”小林井有些没反应过来:“刻一句什么话？” „Carves what/anything, the answer has written on the crowbar, you only need to explain, with your writing, engraves again then.” “刻什么,答案已经写在了铁尺上,你们只需要解读出来,再用你们的文字,刻上即可。” Then, Ye Qing gave Kobayashi Sei this crowbar. 说完,叶青将这根铁尺递给了小林井。 video camera, caught being overly suspicious and fearful on Kobayashi Sei face clearly, received the crowbar with him instantaneous, the right hand obviously sinks downward, why shows such serious expression. 摄像机,清晰地捕捉到了小林井脸上的疑神疑鬼,和他接过铁尺瞬间,右手明显往下一沉,露出为何么会这么沉重的表情。 The Japan Technologies students crash-bang one encircled. 日理工的学生们哗啦一下围了过来。 The climax came, originally this crowbar not only has impressive precise processing technology, but also hid a riddle to write to decode to them. 重头戏来了,原来这根铁尺不仅仅拥有让人惊叹的精密加工技术,还隐藏了一个谜题来给他们破解。 Is good is prepared when Japan Technologies University early, at noon Professor Cai informs them, must bestow a crowbar to work as the gift. They are keeping guessing, this crowbar can have what trick. 好在日理工大学这边早有准备,中午蔡教授通知他们,要赠送一根铁尺当礼物时。他们就在不停猜测,这根铁尺会有什么猫腻。 Therefore needs to load in the quakeproof metal box, many town/subdues gathering place instruments that the pack hits, was brought multimedia center by them. 所以原本需要装入防震金属箱内,打包打走的许多镇场子仪器,也被他们带到了多媒体中心。 The crowbar on a 30 many centimeters appearance, above dial gauge has not even labelled. Kobayashi Sei they believe that even if there is truth, they can still decode with ease. 铁尺也就三十多厘米长的样子,上面连刻度表都没有标注。小林井他们相信,即使存在谜底,他们也能轻松破解开来。 This self-confidence, stems from device that they carry. 这个自信,源于他们所携带的设备。 A Nikon S1500 industry electronic digital microscope, was moved to the table by the Japan Technologies students. 一台尼康S1500工业电子数码显微镜,被日理工的学生们搬到了桌子上。 Nikon Company, is one of the world top grade optical eyeglass Factory. The microscope that they put out, is in the optical microscope at present, the effective amplification multiple highest microscope, does not have one. 尼康公司,是世界顶级的光学镜片工厂之一。他们拿出的这台显微镜,是目前光学显微镜中,有效放大倍数最高的显微镜,没有之一。 hēng hēng any trick, under this most top grade optical microscope, nowhere hides. 哼哼任何猫腻,在这台最顶级的光学显微镜下,都无处所藏。 When the Japan Technologies University students, put up the microscope, when looks at the liquid-crystal display on microscope. 然而当日理工大学的学生们,架好显微镜,把目光转向显微镜上的液晶显示器时。 Their responses, detonating an grenade were more exaggerating. 他们的反应,比引爆了一颗手雷还夸张。 , They will draw back in the future one step. 唰地一下,他们往后退了一步。 „This is impossible!” Kobayashi Sei yelled in mother language: „Why is its surface even?” “这不可能！”小林井用母语大叫道:“为什么它的表面是平的？” Other students, generally also yes fantasy expression. 其他学生,大抵也是活见鬼表情。 Because of them just the enlargement ratio, adjusted to 1200 times of best observation multiple times, sees the surface of this crowbar unexpectedly, is still smooth. Although does not have the mirror is so even, but approaches the ordinary steel with the naked eye directly, observes its surface to be similar. 因为他们刚刚把放大倍率,调到一千两百倍的最佳观察倍数时候,竟然看见这根铁尺的表面,依旧平滑。虽然没有镜子那么平,可是和肉眼直接靠近普通钢铁,观察它的表面差不多。 To study metal, first step is to study its attribute. 想要研究金属,第一步就是研究它的表征。 Enlarges 1200 times, can see the metal surface microstructure directly, for example on metal, just like snowflake same martensite and Austenite. 放大一千两百倍,可以直接看见金属表面的显微结构,比如金属上面,宛若雪花一样的马氏体与奥氏体。 Similarly, their visual observation this crowbar, has not discovered the trick, naturally thinks that was hidden under the naked eye not obvious micro organization. 同样,他们肉眼观察这根铁尺,没有发现猫腻,自然认为被隐藏在了肉眼不可见的显微机构下。 Finally what did they see? 结果他们看见了什么？ If beforehand carving characters, to them, may be called Hard Grade processing technology. The smooth attribute of that this crowbar, is equivalent to frightened level processing technology. 如果说之前的刻字,对他们来说,堪称困难级加工技术。那这块铁尺的平滑表征,就相当于恐惧级加工技术。 Took the Boss effort, they constrain the fear in heart , to continue to study this crowbar. 费了老大力气,他们才压抑住心中的恐惧,继续研究起这根铁尺。 The time bit by bit is passing by, Japan Technologies University, happily had flown Siberia before, exchanges dignifiedly, goes wild. 时间在一点一点过去,日理工大学这边,之前得意早就飞到了西伯利亚,换上凝重,抓狂。 Because their what/anything could not find, regardless of observes with what way. The surface of this crowbar, complete vast stretch of flat land, let alone the trick riddle topic, was not the black color spot could not find including one. 因为他们什么都找不到,无论用什么方式观察。这根铁尺的表面,全部一马平川,别说猫腻谜题,连一个不是黑色的色斑都找不到。 „hā hā you look at their puzzled appearances.” “哈哈你们看他们纠结的样子。” „Was perplexed, makes them look down on us to try again?” “被难住了,再让他们小瞧我们试一试？” „I thought that...... they need Detective Conan to save the scene!” “我觉得……他们需要名侦探柯南来救场！” The time has passed by for a half hour, Kobayashi Sei difficult raising the head, on the face is the beads of sweat: „After...... passes through us to study consistently, on this crowbar, as if no mystery.” 时间一直过去了半小时,小林井艰难的抬起头,脸上全是汗珠:“经……经过我们一致研究,这根铁尺上,似乎没有奥秘。” „Has.” The reply of Ye Qing neither slow nor hurried, making Japan Technologies that group of students be about to be in deep sorrow. “有。”叶青不紧不慢的回答,让日理工那帮学生都快痛不欲生了。 „You have surveyed, the length of this crowbar?” “你们测量过,这根铁尺的长度么？” „Has...... has measured.” Kobayashi Sei puts out a hand-held distance gauge: „This is the distance gauge of our Nikon Company production, not only the length, even/including Kuangao we have also measured.” “有……有测过。”小林井拿出一台手持测距仪:“这是我们尼康公司生产的测距仪,不仅长度,连宽高我们也测过。” „Its length is 0.32569 meter.” “它的长度是0.32569米。” „Ruler energy is long, answer in its length.” The Ye Qing station, shook the head: „precision of distance gauge is insufficient, you change a more advanced instrument, surveys its length.” “尺能量长,答案就在它的长度上。”叶青站了起来,摇摇头:“测距仪的精度不够,你们换更先进的仪器,来重新测量一下它的长度。” „But we to the ten thousandth of a meter, its length are too precisely long, the micrometer is unable to measure. Wants more precise, that must use the laser interferometer.” “可是我们已经精确到了丝米,它的长度太长,千分尺无法测出来。想要更精确,那就要用激光干涉仪。” „Can your laser interferometers, which rank precisely to?” “你们的激光干涉仪,可以精确到哪个级别？” „Nano-meter.” In the Kobayashi Sei sound led to roar: „We can precisely to 2 nanometers, what significance but surveys this crowbar to have?” “纳米级。”小林井的声音中带了一丝咆哮:“我们可以精确到二纳米,但是测量这根铁尺有什么意义？” „2/1000000000 meters precision, the present stage simply does not have machine tools processing to come out. Even if our Industrial Machine Tool , can only metal material precision, determine in the 50 nano.” “十亿分之二米的精度,现阶段根本没有机床加工出来。哪怕我们的工业母机,也只能把金属材料的精度,确定在五十纳米。” „0.32569 meter?” Ye Qing vision solemn said a number. “0.32569米？”叶青目光严肃地说出一段数字。 „What do you mean? This length, is we measures.” “什么意思？这个长度,是我们测出来的。” „Behind also has 734.” Ye Qing visits him, sent out a number. “后面还有734。”叶青看着他,报出了一段数字。 Kobayashi Sei some do not believe the said/tunnel: „You precision as precise as 0.1?” 小林井有些不相信地道:“你们把精度精确到了0.1丝？” „Since your laser interferometers, cannot achieve precision Standard, I told you accurate answer.” “既然你们的激光干扰仪,也达不到精度标准,那我就告诉你准确答案。” Ye Qing tranquil saying: „We precision, framed in 1/2 nanometers, was 5/10000000000 meters precision.” 叶青平静的说道:“我们把精度,定格在了二分之一纳米上,也就是一百亿分之五米的精度。” „Ruler energy is long.” “尺能量长。” „If you in vacuum tank, with a more advanced interferometer, measures the length of this crowbar.” “如果你们在真空箱里,用更先进的干扰仪,去测这根铁尺的长度。” „Will obtain such a group of numbers Something went wrong, very simple one group of decimal digits, so long as this group of figures, changes into your writing with the decimal base, can obtain you to in an above quarter character.” “会得出这样一组数字[Not Found],很简单的一组十进制数字,只要把这组数字,用十进制换成你们的文字,就能得出你们要在上面刻的字。” Static. 静。 The time old person in multimedia center, threw down the time bomb, making their facial expressions instant frame. 时光老人在多媒体中心内,丢下了时光炸弹,让他们的神情瞬时定格。 The length of ruler, transforms their writing? 把尺子的长度,转换成他们的文字？ Obtaining...... 得出…… Character that they must carve? 他们要刻的字？
