Next morning, Ordinary Differential Equation (ODE) has the first class. 第二天上午,常微分方程开第一堂课。 Lu Zhou enters the classroom, felt that the atmosphere in classroom instantaneously became somewhat strange. 陆舟一进教室,感觉教室里的气氛瞬间变得有些诡异了。 Should count 12 classes usually to attend class together, the students of this little while two classes sit here, the classroom was pushed chock full. 应数一二班平时是一起上课的,这会儿两个班的学生都坐在这里,教室被挤得满满当当的。 Was by eye is staring, Lu Zhou also really somewhat feels timid at heart. 被一双双眼睛这么直勾勾地盯着,陆舟心里还真有些发怵。 Let alone, these lines of sight also follow the low voice discussion. 更何况,这一道道视线还伴随着小声的议论。 „, The number should Lu Zhou!” “哇,数应一的陆舟！” „That counts a minute of double perfect score high study god!” “那个高数数分双满分的学神！” „Counts minute to be nothing high, others in the suspicion textbook proved! Testing a perfect score is not relaxed!” “高数数分算个屁啊,人家连教科书上的猜想都证明了！考个满分不是轻轻松松！” „Supplements one, is the textbook of graduate student......” “补充一句,还是研究生的教科书……” „Yeah, do not envy others is so flamboyant, I listened to a student council buddy saying that this fellow has not gone back throughout entire summer break. We when hit to rub to rub, this buddy teaches building cultivator to brush the book in A daily.” “哎,也别羡慕人家这么牛逼,我听一学生会的哥们儿说,这家伙整个暑假都没回去。我们在打撸啊撸的时候,这哥们儿天天在a教楼修仙刷书。” „Originally is in the immortal gate the person...... this feared that must cross the tribulation.” “原来是仙门中人……这怕是要渡劫了。” „I...... shake intimidated!” “我……震怖！” I scratch, this flock of draft animals discussed others time can low voice. 我擦,这群牲口议论别人的时候能不能小声点。 Although listens to be very crisp. 虽然听着还是挺爽的。 At this moment, the teaching classes teacher came. 就在这时,任课教师来了。 The professor in coming in classroom, Lu Zhou is also knew that leads Professor Liu Xiangping of his data modeling competition. 进来教室的教授,陆舟也是认识的,正是带他数据建模大赛的刘向平教授。 This venerable comes the time of classroom, has his unique style very much, not late one second, certainly not early to one minute. 这位老先生来教室的时间,也很有他独特的风格,绝不迟到一秒,也绝不早到一分钟。 „Is standing doing, immediately must attend class, has not looked for a position to sit.” Meanly smiles to Lu Zhou, Professor Liu placed on the insulated cup the multimedia platforms. “站着干什么,马上要上课了,还不找个位置坐着。”对陆舟友善地笑了笑,刘教授将保温杯放在了多媒体讲台上。 „, I also just came.” “呃,我也是刚来。” Lu Zhou smiles embarrassed, took a look at the classroom back row rapidly, discovered the own three roommates sit is very scattered, obviously cannot successfully occupy the position, therefore then prepares to turn around other classroom to move a stool. 陆舟不好意思笑了笑,迅速瞅了眼教室后排,发现自己三个室友坐的都很分散,显然是没能成功占到位置,于是便准备转身去别的教室搬个凳子。 At this moment, sat the first row of buddy to stand up suddenly, tidied up the teaching material and pen on bag table, gave the hand signal of invitation. 就在这时,一位坐第一排的哥们儿忽然站起身来,收拾了桌上的教材和笔袋,做了个请的手势。 „Boss, you sits here.” “大佬,您坐这儿。” „No, does not use, I went to the next door classroom to move a stool to come on the line.” Lu Zhou does not know whether to laugh or cry declines. “不,不用了,我去隔壁教室搬个凳子来就行了。”陆舟哭笑不得地谢绝道。 „, I did not move the stool to be OK, only asked the note to read taking advantage of me!” The buddy persists in saying very much tenaciously. “不不不,我去搬凳子就可以了,只求笔记借我一阅！”那哥们很固执地坚持道。 Said taking advantage of the note, so long as also came back on time, casually taking advantage without issue. 借笔记好说,只要按时还回来,随便借没问题。 However, issue not in note. 然而,问题不是在笔记上。 Rather, now this situation, Lu Zhou where also dares to sit the first row! Originally the body on bringing eye-catching debuff, only feared when the time comes moves a stool quietly, the people in entire classroom must voluntarily not be salute to him...... 而是,现在这种情况,陆舟哪里还敢坐第一排啊！本来身上就自带吸引眼球的debuff,到时候只怕悄悄挪个凳子,全教室的人都得不自觉地向他行注目礼…… This being nervous and uneasy feeling, was really uncomfortable. 这种如芒在背的感觉,实在是太难受了。 Lu Zhou said that anything is not willing to sit down, went to nearby classroom without delay, moved a stool to come back, sits in last row of Huang Guangming's side. 陆舟说什么也不肯坐下,二话不说去了旁边教室,搬了个凳子回来,坐在最后一排黄光明的旁边。 Turns over to curiously curiously, these people always impossible to have looked back him in attending class specially? 好奇归好奇,这些人总不可能在上课的时候专门回过头来看他吧？ Professor Liu Xiangping smilingly visits him, did not speak. 刘向平教授笑眯眯地看着他,也不说话。 The ting resounds, the curriculum starts. 铃声响起,课程开始。 Professor Liu emitted ppt, smiles, said. 刘教授放出了ppt,笑了笑,说道。 „Teaching material turns the introduction.” “教材翻到绪论。” When others turn out the note prepares to listen, Lu Zhou also opened «Machine learning Actual combat Printed lecture», starting to study these specially is the accent. Teaches the artificial intelligence the entering step algorithm of design. 在别人翻出笔记准备听讲的时候,陆舟也翻开了《机器学习实战讲义》,开始研究那些专门为调.教人工智能而设计的进阶算法。 Without the assistance of concentration capsule, wants to have a thorough understanding of a book is not really easy completely. However is good because of the rank of branch division/discipline, not only strengthens the knowledge the utilization ability, has a big promotion to the learning capability of knowledge. 没有专注胶囊的辅助,想要完全吃透一本书着实不容易。不过好在主干学科的等级,不但强化知识的运用能力,对知识的学习能力也有着不小的提升。 So far, this and dictionary equally thick teaching material, he had looked at half. 到目前为止,这本和字典一样厚的教材,他已经看了一半了。 However even so, he inspected the Xiao Ai core code yesterday evening time, still discovered that inside lots, are unable to understand at his present state-of-art. 然而即便是如此,昨天晚上他检查小艾核心代码的时候,依然发现里面很多东西,以他现在的知识水平是无法理解的。 Meanwhile, Professor Liu continues to teach on the stage. 与此同时,刘教授在台上继续讲课。 „...... Requirements of the high-school mathematics to the equation, usually the relations between known quantities and unknowns in research problem looks, lists to contain the equations or the equation sets of one or more unknown, then solves.” “……中学数学对方程的要求,通常是把研究问题中的已知数和未知数之间的关系找出来,列出包含一个或多个未知数的方程式或方程组,然后求解。” „However in the actual work, we will often come across some characteristics and above equation completely different issues. For example the secular variation of material under controlled condition, must seek the rule of its movement and change. Again for example rocket under the engine promotes in the space flight, must seek the track that it flies. This requests us to obtain function analysis formula formally by the existing data, rather than calculates the specific unknown through the known function that ‚topic’ gives.” “而在实际的工作中,我们常常会遇到一些特点和以上方程完全不同的问题。比如物质在一定条件下的运动变化,要寻求它的运动、变化的规律。再比如火箭在发动机推动下在空间飞行,要寻求它飞行的轨道。这就要求我们以现有数据求得形式上的函数解析式,而不是通过‘题目’给出的已知函数来计算特定的未知数。” „Ordinary Differential Equation (ODE) is one quite useful ‚tool’ division/discipline, has the important application in many disciplines and branches, from the automatic control of machinery the trajectory computation of rocket bomb flight vehicle, and even chemical reaction process stability research wait.” “常微分方程是一门相当有用的‘工具’学科,在很多学科领域都有着重要的应用,从机械的自动控制到火箭导弹飞行器的弹道计算、乃至化学反应过程稳定性的研究等等。” At this point, Professor Liu smiles: „Therefore, you may result in well this class of pleasant to hear on the number system. This class could not learn, waits for in later the job, but let alone you were gold/metal big graduate, let alone was I teaches, lost face too!” 说到这里,刘教授笑了笑:“所以啊,你们应数系可得好好听这门课了。这门课学不好,等以后上了工作岗位,可别说你是金大毕业的,也别说是我教的,太丢人！” This Professor Liu is also an interesting person, does not teach aridly, easy to understand that the complex thing can speak, the easy to understand thing can develop the thorough domain. 这刘教授也是个有趣的人,讲课不枯燥,复杂的东西能讲的通俗易懂,通俗易懂的东西又能拓展到深入的领域去。 The bright brother who does not listen, this also put down cell phone, stares at ppt on theater curtain to look meticulously, once for a while records anything in the notebook. 就连一项不听讲的光明兄,这回也是放下了手机,一丝不苟地盯着幕布上的ppt看,时不时在笔记本上记些什么。 The college course advances the speed to be quick, in 1 points, Professor Liu is no exception only here, teaching simply flipping through the book is quicker. 大学课程推进速度很快,唯独在这里一点上,刘教授也不例外,讲课简直比翻书还快。 In the classroom takes the note is impossible, the classroom of university can keep up with the teaching speed of teacher is very good. The following student does not stop using the cell phone photograph, simply like the press conferences of certain science companies. 课堂上做笔记是不可能的,大学的课堂能跟上老师的讲课速度就已经很不错了。下面的学生不停用手机拍照,简直像极了某些科技公司的新闻发布会。 Half class in the past, the basic definition and Geometry explanation of largest chapter of differential equation and solution then rode the rocket general, was the first section of second largest chapter of primary General points method- appropriate equation. 半节课过去,第一大章的微分方程及其解的基本定义和几何解释便坐火箭一般过完了,紧接着就是第二大章初等积分法的第一小节-恰当方程。 The difficulty promotes instantaneously. 难度瞬间升级。 Big pile of new knowledge points throw, many have not prepared a lesson this chapter of students to complain constantly. Then is on the stage the professor has the teaching skill of simplifying, some elementary school dregs also feel somewhat cannot endure. 一大堆新知识点扔过来,不少还没预习到这一章的学生们叫苦不迭。便是台上教授有着化繁为简的教学功力,一些小学渣们也顿感有些吃不消。 „Knowledge node also said was similar, believes that you got down also to prepare a lesson, we presented a problem to practice acquiring a skill.” Professor Liu smiles, presses under the laser pen, ppt turned the next page, „this problem, you calculate, if who can, be able the coming up blackboard writing.” “知识点也讲的差不多了,相信你们自己下去也预习过,我们来做道题练练手。”刘教授笑了笑,按了下激光笔,ppt翻到了下一页,“这道题,你们算算,谁要是会,可以上来板书。” 【Judged whether \ { y2 / ( x-y ) 2-1 / x } dx + \ { 1 / y-x 2 / ( x-y ) 2 } dy = 0 is the appropriate equation, and sought the soluation of equation.】 【判断\{y2/(x-y)2-1/x}dx+\{1/y-x2/(x-y)2}dy=0是否为恰当方程,并求方程解。】 Lu Zhou found time to sweep that topic on ppt, saw no difficulty, then has not cared , to continue to read own book. 陆舟抽空扫了眼ppt上的那道题目,见没什么难度,便没放在心上,继续看自己的书。 However, other students did not have him is so relaxed. 然而,其他学生就没他这么轻松了。 Just contacted this class, many people only prepared a lesson Chapter 1, has not prepared a lesson the second largest chapter, looks that the appropriate equation four characters is a face compel ignorant. Also only then these study Tyrant Men, with setting pen to paper to consider as finished at the scratch paper performance. 刚接触这门课,很多人只预习了第一章,还没预习到第二大章,看着恰当方程四个字都是一脸懵逼。也只有那些学霸们,才拿着笔在草稿纸上演算了起来。 Two minutes pass by, in classroom completely silent. 两分钟过去,教室内鸦雀无声。 „How does no one raise hand?” Professor Liu smiles, jokes, „you may be able to test into 985 students, is always insufficient to recommend for admission to school?” “怎么没人举手？”刘教授笑了笑,开了个玩笑说,“你们可都是能考上985的学生,总不至于都是保送上来的吧？” Sits in the first row of that two classes of buddies, smiles embarrasedly, said weakly presented aspiration: „That big shot have not raised hand, where we dare to raise hand.” 坐在第一排的那位二班的哥们儿,讪讪笑了笑,弱弱地道出了在座各位的心声:“那位大佬都没举手,我们哪敢举手。” Front many people, conform to the nod in abundance. 前排不少人,纷纷符合点头。 Calculates the person who has, but no one dares to raise hand. 算出来的人还是有的,但没人敢举手。 Professor Liu pretends not to hear, hehe smiles, „no one does really come out to answer? It seems like I must give a good luck. That line! Who can solve this problem, usually divides the additional 10 points, I inscribe to him.” 刘教授装作没听见,呵呵笑了笑,“真没人出来答？看来我得给点彩头咯。那行吧！谁能解出来这道题,平时分加十分,我给他记上。” Still is studying «Machine learning» Lu Zhou, does not cover the potential of ear to raise hand by the thunderclap anxiously instantaneously, the speed that raises hand still has a scare in manual computation Huang Guangming side. 还在研究《机器学习》的陆舟,以迅雷不急掩耳之势瞬间举起手来,那举手的速度把旁边还在笔算的黄光明吓了一跳。 However Lu Zhou has not visited him, but the flashing eyes are staring at the sample question on ppt. 然而陆舟没有看他,只是目光炯炯地盯着ppt上的例题。 Ten points usually divides! 十分的平时分啊！ Such as simple as topic of explosion, simply is white collect! 就这么一道简单到爆炸的题,简直是白捡！ However Professor Liu does not give him very much the face, smiles to him, said unrestrained/no trace of politeness: „You put down the hand, this does not have your share. Either you like lifting are lifting, I will not select your name in any case. The end of the period can test the perfect score, usually divides all gives you. Missed a point, usually divides for one point not to have!” 然而刘教授很不给他面子,冲着他笑了笑,毫不客气说:“你把手放下,这十分没你的份。要么你爱举着就举着,我反正不会点你的名。期末能考到满分,平时分全给你。差了一分,平时分一分没有！” Lu Zhou: „......” 陆舟:“……” All schoolmates hold breath cold air. 全班同学倒吸一口凉气。 Worthily is real studies the tyrant, did this start the scheduled perfect score? 不愧是真・学霸,这都开始预定满分了吗？ Smiles awkwardly, Lu Zhou takes back the hand that raises. 尴尬笑了笑,陆舟收回举起的手。 At this moment, besides mmp, his character does not want to say. 此时此刻,除了一句mmp之外,他一个字也不想讲。
