While Connie brings the cooperation research and development agreement is starting off, That side Professor Pablo Herrero, sent a postgraduate candidate to Lu Zhou. 在康尼带着合作研发协议上路的同时,巴勃罗・赫雷罗教授那边,也派了一名博士生到陆舟这边。 However, does not come to Princeton. 不过,不是来普林斯顿这边。 But goes to be located in Surrott Research institute of California. 而是前往位于加州的萨罗特研究所。 With the signature of cooperation research and development agreement, the research about superconducting material has started. Two research team combinations, the progress of topic looked like grew the wing. 随着合作研发协议的签署,关于超导材料的研究已经开始。两支研究团队强强联手,课题的进度就像是插上了翅膀。 However, even a situation excellence, Lu Zhou had not expected that can obtain the result immediately. 不过,即便形势一片大好,陆舟也没有期望能够立刻得到结果。 The scientific essence is to try wrong, but they need to attempt „mistake” also has. 科学的本质是试错,而他们需要尝试的“错误”还有很多。 The superconducting material is only one point in nuclear fusion project, is actually not its entirety. 超导材料只是核聚变工程中的一环,却并非是它的全部。 With starting of carbon nanomaterials superconductivity topic, Lu Zhou also started his fundamental research to the plasma. 随着碳纳米材料超导课题的上马,陆舟这边也开始了他对等离子体的理论研究。 About controllable nuclear fusion of magnetic confinement, Tokomak or Stellarator, are facing the common difficult problem. But the three essential factors of most core, are the high temperature and high density, and long-term restraint! 关于磁约束的可控核聚变,无论是托卡马克还是仿星器,都面临着共同的难题。而其中最核心的三要素,便是高温、高密度、以及长时间的约束！ Former's solution currently speaking many, quite common has the laser ignition, there are to the plasma energizes heats up, there are to the plasma volume compresses exothermic...... naturally, can many plans on together. 前者的解决方案目前来讲还是很多的,比较常见的有激光点火,也有对等离子体本身通电进行加热,也有对等离子体体积压缩放热……当然,也可以多种方案一起上。 However, what is truly difficult after is, both high density and long-term restraint. 然而,真正困难的是后两者高密度和长时间的约束。 The plasma is not a very law-abiding thing, according to formula re = pvd / of Reynolds number, by the high density plasma of electromagnetic field fetter, had big Reynolds number, any small perturbation will make entire system by the plasma being constituted produce the disorder and irregular turbulent flow. 等离子体并不是一种很安分的东西,根据雷诺数的公式re=pvd/,被电磁场束缚的高密度等离子体,拥有较大的雷诺数,任何微小的扰动都会使整个由等离子体构成的体系产生紊乱、不规则的湍流。 Relatively speaking, Stellarator has certain advantage in the restraint plasma, needs little to consider many perturbational factors compared with Tokomak. 相对而言,仿星器在约束等离子体上具备一定的优势,比起托卡马克来说需要少考虑很多扰动因素。 However even were short of many perturbational factors, wants these not law-abiding plasma confinement in a narrow and small space, as before is not an easy matter. 然而即便是少了很多扰动因素,想要将这些不安分的等离子体约束在一个狭小的空间内,依旧不是一件容易的事情。 The strength of theory, then great in this. 理论的力量,便伟大于此。 When can depend upon, and succinct theoretical model, even it is only one uses the convenient phenomenological model even if, can have the extraordinary significance to the entire nuclear fusion project. 当有一个可以依靠的、并且简洁的理论模型,甚至于哪怕它只是一个用起来顺手的唯像模型,都能对整个核聚变工程产生非同寻常的意义。 It can be said that on the research of present stage, the controllable nuclear fusion technology in one of bottlenecks the theoretical field faces, 可以说,就现阶段的研究而言,可控核聚变技术在理论领域所面临的瓶颈之一,便是难以针对特定聚变装置中的等离子体,建立一个可靠的理论模型。 Is puzzling Lu Zhou also this. 困扰着陆舟的也正是这点。 Euler Lagrange equation or the ns equation, these seem like the indication very succinct theory, when was used to solve the specific problem, the difficulty will assume index -type increase. 无论是欧拉-拉格朗日方程还是ns方程,这些看起来表述非常简洁的理论,当被用于解决具体的问题时,难度都会呈指数式的增加。 If the existence and smooth of ns equation are the century difficult problems of math, then satisfied ns equation the turbulent flow phenomenon of viscous fluid, is the Physics century difficult problem. 如果说ns方程的存在性与光滑性是数学的世纪难题,那么满足ns方程的粘性流体的湍流现象,便是物理学的世纪难题。 But he studies „the turbulent flow phenomenon of plasma”, is one point in this century difficult problem. 而他研究的“等离子体的湍流现象”,便属于这个世纪难题中的一环。 The higher research institute office, sits Lu Zhou before desk, is staring at the glass steel cup on table steadily, looking like in a daze to be the same. 高等研究院办公室,坐在办公桌前的陆舟,正目不转睛地盯着桌子上的玻璃钢杯,就像是在发呆一样。 The cup is not big, is similar to the cover of thermo, inside is abundant the liquid looks like the boiling water the same as tumble, and unceasingly from the edge overflow white smoke of rim. 杯子不大,和保温瓶的盖子差不多,里面盛着的液体就像是开水一样翻滚着,并且不断从杯口的边缘溢出白烟。 Held the lesson plan to walk, Vera who is preparing to report the previous section theory of numbers class teaching situation, looks at Lu Zhou one that was in a daze curiously. 抱着教案走了过来,正准备汇报上节数论课教学情况的薇拉,好奇地看着了正在发呆的陆舟一眼。 In her mind, Lu Zhou barely uses the time on being in a daze. 在她的印象中,陆舟很少将时间用在发呆上。 „Professor, are you doing?” “教授,您在干什么？” „Looks for the inspiration.” “寻找灵感。” Obviously, Lu Zhou is not in a daze, but the mentality reached the impass. 显然,陆舟并不是在发呆,只是思路陷入了僵局。 Is staring in the cup up and down the surges liquid, the pen tip in his hand starts to ignite in the notebook gently. 盯着杯子里上下翻腾的液体,他手中的笔尖开始轻轻地在笔记本上点着。 Although on that short one line of equations. 虽然在那上面,只有短短的一行方程式。 【P \ {? v /? t +( v. Δ) V } =-Δ p + pg + Δ 2 v】 【p\{?v/?t+(v.Δ)・v}=-Δp+pg+Δ2v】 The equation has nothing difficultly, the left is the momentum rate of change of fluid unit, the right is various strength of function in fluid unit. 方程本身没什么难的,左边是流体单元的动量变化率,右边是作用在流体单元上的各种力。 However, no difficulty, merely is only the equation...... 然而,没什么难度的,也仅仅只是方程本身而已…… Vera has not gone to disturb him to look for the inspiration, but is accompanying by him curiously, is staring at the cup on table together. 薇拉没有去打扰他寻找灵感,只是好奇地陪着他旁边,一起盯着桌上的杯子。 , The white smoke that overflows from the rim is gradually getting more and more weak, in the liquid together with cup were also getting fewer and fewer. 渐渐地,从杯口溢出的白烟越来越弱,连同杯子里的液体也越来越少了。 After a while, the liquid in cup completely vanishes, Vera blinks, approaches to look. 过了一会儿,杯子里的液体完全消失,薇拉眨了眨眼,凑近了看去。 „It vanished.” “它消失了。” „Yes.” “是的。” Lu Zhou has not explained anything, hints Vera to draw back backward several steps. 陆舟没有解释什么,示意薇拉向后退开几步。 Then, he put on is thrown by him in the heat insulation glove of table corner, raised a terse and forceful liquid helium bottle from the table, probably poured out wine to be the same, sprinkled toward that glass steel cup. 接着,他戴上了被他扔在桌角的隔热手套,从桌子下面提起一支短小精悍的液氦瓶,像是斟酒一样,往那玻璃钢杯里面泼去。 The glass steel cup was filled by the transparent liquid again, the liquid level boiled, and sending out white smoke. 玻璃钢杯重新被透明的液体斟满,液面重新沸腾了起来,并且散发白烟。 After the liquid helium bottle puts down, Lu Zhou maintains safely is being away from , to continue calmly to look liquid helium that in the cup boils. 将液氦瓶放下之后,陆舟保持着安全地距离,继续静静地看着杯中沸腾的液氦。 The liquid helium under ultra-low temperature presents the superfluid phenomenon, the coefficient of viscosity is close to 0, the Reynolds number tends to infinity, is fluid close to perfect condition. 在超低温下的液氦呈现超流体现象,粘度系数接近0,雷诺数趋向无穷大,算是一种接近理想状态的流体。 Although seems like it compares „stay still” the liquid is not more law-abiding, the computation load of but from the perspective of math, it involving, instead is much smaller. 虽然看起来它比“静止不动”的液体更加不安分,但从数学的角度而言,它所涉及到的运算量,反而却要小得多。 In some sense, plasma in magnetic confinement vacuum chamber, is existence that has the big Reynolds number. Has big density p, as well as big diameter D, just because of existence of coefficient of viscosity, making it like the liquid helium not exaggerating. 从某种意义上来讲,在磁约束真空室中的等离子体,也是一种具有大雷诺数的存在。拥有较大的密度p,以及不小的直径d,只不过因为粘度系数的存在,使它不像液氦那么夸张而已。 But this also means that it form in math, by far compared with superfluid condition liquid helium by far complex many...... 而这也意味着,它在数学上的形式,远远比超流体状态的液氦远远复杂的多…… „Professor, why I felt, in the office is so cold?” “教授,我为什么感觉,办公室里这么冷？” Sat holds the arm to hit to tremble in Hardy of another side desk, looked around to Lu Zhou under. 坐在另一边办公桌的哈迪抱着胳膊打了个寒颤,向陆舟那边张望了下。 „Because I poured a liquid helium.” Was saying superficially serious thing, Lu Zhou thought of anything suddenly, looked that to sat in window nearby Qin Yue said that „under Qin Yue, opened the window for me.” “因为我倒了点液氦。”轻描淡写地说着不得了的东西,陆舟忽然想到了什么,看向了坐在窗户边上的秦岳说道,“秦岳,替我把窗户打开下。” „Good professor.” Qin Yue put down the pen in hand, windowing. “好的教授。”秦岳放下了手中的笔,去开窗子。 After the window opened, in the office was gradually warmer. 窗户打开了之后,办公室里渐渐暖和了许多。 Suddenly realized anything, Hardy started to pack the thing on table silently, prepared to sneak off. 忽然意识到了什么,哈迪开始默默地收拾了桌上的东西,准备开溜。 Noticed his movement, Lu Zhou asked: „Do you go?” 注意到了他的动作,陆舟问道:“你去哪？” Proposes hand of backpack, Hardy is smiling awkwardly, „I...... suddenly think that several literature have not looked, must go to a library.” 提着背包的手一顿,哈迪尴尬地笑了笑,“我……突然想起来还有几篇文献没看完,得去一趟图书馆。” „Helium also does not have the poison, leaving is so anxious,” Lu Zhou sighed, with wearing that hand of glove, attained near the window to put glass steel cup, making it sun. “氦气又没有毒,别这么紧张,”陆舟叹了口气,用戴着手套的那只手,将玻璃钢杯子拿到了窗户边上放着,让它晒晒太阳。 In comparison, this gadget is more dangerous. 相比之下,这玩意儿更危险。 If the finger did not bump into carefully, freezing a skin that is light. 若是手指不小心碰到了,冻掉一层皮那都是轻的。 Before returning to the desk sits down, Lu Zhou thought of anything suddenly, looked that said to Vera. 回到了办公桌前坐下,陆舟忽然想到了什么,看向薇拉说道。 „Partial differential equation have you studied?” “偏微分方程你有研究过吗？” Seriously thought deeply about the moment, Vera nods, actually shakes the head, „has studied......, but studies aren't many, what matter has to need me to help?” 认真思索了片刻,薇拉点了点头,却又摇了摇头,“研究过……但研究的不多,有什么事情需要我帮忙吗？” Lu Zhou thought a while, shakes the head, „, is not ok, you continue the topic of hail suspicion.” 陆舟想了一会儿,摇了摇头,“不,还是算了,你继续冰雹猜想的课题。” Now in topic-based group of hail suspicion on three people, if screened out from the topic-based group Vera, only depended on Qin Yue and Hardy two, perhaps he could not see that day that forever this topic completed. 现在冰雹猜想的课题组里就三个人,如果将薇拉从课题组中抽走了,只靠着秦岳和哈迪两个,他恐怕是永远看不到这个课题完成的那一天了。 The expression of little miss somewhat loses slightly. 小姑娘的表情微微有些失落。 She wants to add on busy of professor. 她很想帮上教授的忙。 But, her ability insufficient...... 但果然,她的能力还是不够…… Suddenly thinks in own office also the person, Lu Zhou looked to sat in the office corner, the line of sight continuously once for a while in toward Wei Wen that him glances. 忽然想到了自己的办公室里还有一个人,陆舟看向了坐在办公室角落,视线一直时不时地在往他这边瞟的魏文。 „Wei Wen, do you have the research to the partial differential equation?” “魏文,你对偏微分方程有研究吗？” Seemed like waits till the professor to look finally to here, Wei Wen pushes the eyeglasses unemotionally, the corners of the mouth actually brought back a smiling face. 似乎是终于等到了教授看向这边,魏文面无表情地推了推眼镜,嘴角却是勾起了一丝笑容。 „Has, how?” “有,怎么了？” The partial differential equation besides the functional analysis, one of domains he most excels. 偏微分方程是除了泛函分析之外,他最擅长的领域之一。 In the undergraduate stage, he then follows the Yanda (Yanshan University) professor, has participated in similar research. 在本科阶段,他便跟着燕大的教授,参与过类似的研究。 Came to Princeton is so long, now finally is to let him waits till the opportunity that this can flex the muscles. 来了普林斯顿这么久,现在终于是让他等到了这个可以大展拳脚的机会。 For this day, he has prepared is too long. 为了这一天,他已经准备了太久。 He will use oneself strength, proved oneself are in this office second strong existence! 他会用自己的实力,证明自己是这个办公室里第二强的存在！ Lu Zhou thinks, said: „I prepare to open a topic again, about the ns equation.” 陆舟想了想,说道:“我准备再开个课题,关于ns方程。” The curve that the corners of the mouth bring back is gradually stiff, particularly after hearing ns equation name, the smiling face on Wei Wen face seemed like...... no longer was so as if self-confident. 嘴角勾起的弧度渐渐僵硬,尤其是在听到了ns方程这个名字之后,魏文脸上的笑容看上去……似乎不再那么自信了起来。 However, Lu Zhou has not noticed his expression. 不过,陆舟并没有注意到他的表情。 Now he most needs is a manpower, even if can add on 1 to be busy at that being also good. 他现在最需要的就是人手,哪怕是能帮上一点忙那也是好的。 Naturally, the light is a Wei Wen person is insufficient, even his ability is outstanding enough, that is still merely compared to other graduate students. 当然,光是魏文一个人是不够的,即便他的能力足够出众,那也是仅仅是相对于其他研究生而言。 The index finger ignites on the table gently, is thinking deeply about Lu Zhou that also who can help, the eye one brightly, from the office chair sat suddenly fiercely. 食指在桌上轻轻点着,正在思索着还有谁可以帮上忙的陆舟,眼睛忽然一亮,猛地从办公椅上坐了起来。 „Right, how that person forgetting......” “对啊,怎么把那个人给忘了……” Is thinking aloud low voice, the Lu Zhou sound is somewhat excited. 小声自言自语着,陆舟的声音有些兴奋。 If he, said that does not permit also really to add on oneself this busy! 如果是他的话,说不准还真能帮上自己这个忙！
