random中nextint()如何设定最小值

您好,如果调用.nextInt(),-MaxValue到MaxValue,.nextInt(n)才是0到n.

下面是JAVA API的原段

nextInt()

Returns the next pseudorandom, uniformly distributed int value from this random number generator"s sequence.。因为nextint(n)只能是0到n,此处n必须为正整数,如果为负则报错。

但如果你想它也能生成负数的话,直接int value=-rand.nextInt(30);即可

表示生成的是-30到0的。

控制理论中,Lyapunov利亚普诺夫稳定性理论的定义里面,stable 和uniformly stable到底有什么区别?

举个例子,当L指数大于零时,两个一开始相互靠近的点,在经过一段时间的运动后,彼此之间的距离和位置会变得很大。也因此证明,这个系统是不稳定的,是混沌动力系统,该系统是对初始条件很敏感的系统。类似蝴蝶效应。如果L指数小于零,两个一开始相互靠近的点,在经过一段时间的运动后,依然相互靠近。就说明该系统是稳定的。

科技英语的特点

  科技英语作为一种重要的英语文体,包含大量与科技相关的专业词汇,具有词义多、长句多、被动句多、词性转换多、非谓语动词多、专业性强等特点。接下来我为大家整理科技英语的特点,希望对你有帮助哦!   一、大量使用名词化结构   《当代英语语法》(A Grammar of Contemporary)在论述科技英语时提出,大量使用名词化结构(Nominalization)是科技英语的特点之一。因为科技文体要求行文简洁、表达客观、内容确切、信息量大、强调存在的事实。而非某一行为。   Archimeds first discovered the principle of displacement of water by solid bodies.   阿基米德最先发展固体排水的原理。   句中of displacement of water by solid bodies 系名词化结构,一方面简化了同位语从句,另一方强调displacement 这一事实。   The rotation of the earth on its own axis causes the change from day to night.   地球绕轴自转,引起昼夜的变化。   名词化结构the rotation of the earth on its own axis 使复合句简化成简单句,而且使表达的概念更加确切严密。   If you use firebricks round the walls of the boiler, the heat loss. Can be considerably reduced.   炉壁采用耐火砖可大大降低热耗。   科技英语所表述的是客观规律,因之要尽量避免使用第一、二人称;此外,要使主要的信息置于句首。   Television is the transmission and reception of images of moving objects by radio waves.   电视通过无线电波发射和接受活动物体的图象。   名词化结构the transmission and reception of images of moving objects by radio waves 强调客观事实,而"谓语动词则着重其发射和接受的能力。   二、广泛使用被动语句   根据英国利兹大学John Swales 的统计,科技英语中的谓语至少三分之一是被动态。这是因为科技文章侧重叙事推理,强调客观准确。第一、二人称使用过多,会造成主观臆断的印象。因此尽量使用第三人称叙述,采用被动语态,例如:Attention must be paid to the working temperature of the machine.应当注意机器的工作温度。而很少说:You must pay attention to the working temperature of the machine .你们必须注意机器的工作温度。此外,如前所述,科技文章将主要信息前置,放在主语部份。这也是广泛使用被动态的主要原因。试观察并比较下列两段短文的主语。   We can store electrical energy in two metal plates separated by an insulating medium. We call such a device a capacitor, or a condenser, and its ability to store electrical energy capacitance .It is measured in farads.   电能可储存在由一绝缘介质隔开的两块金属极板内。这样的装置称之为电容器,其储存电能的能力称为电容。电容的测量单位是法拉。   这一段短文中各句的主语分别为:   Electrical energy   Such a device   Its ability to store electrical energy   It (Capacitance )   它们都包含了较多的信息,并且处于句首的位置,非常醒目。四个主语完全不同,避免了单调重复,前后连贯,自然流畅。足见被动结构可收简洁客观之效。   三、非限定动词   如前所述,科技文章要求行文简练,结构紧凑,为此,往往使用分词短语代替定语从句或状语从句;使用分词独立结构代替状语从句或并列分句;使用不定式短语代替各种从句;介词十动名词短语代替定语从句或状语从句。这样可缩短句子,又比较醒目。试比较下列各组句子。   A direct current is a current flowing always in the same direction.   直流电是一种总是沿同一方向流动的电流。   Radiating from the earth, heat causes air currents to rise.   热量由地球辐射出来时,使得气流上升。   A body can more uniformly and in a straight line,there being no cause to change that motion.   如果没有改变物体运动的原因,那么物体将作匀速直线运动。   Vibrating objects produce sound waves ,each vibration producing one sound wave.   振动着的物体产生声波,每一次振动产生一个声波。   In communications, the problem of electronics is how to convey information from one place to another.   在通讯系统中,电子学要解决的问题是如何把信息从一个地方传递到另一个地方。   Materials to be used for structural purposes are chosen so as to behave elastically in the environmental conditions.   结构材料的选择应使其在外界条件中保持其弹性。   There are different ways of changing energy from one form into another.   将能量从一种形式转变成另一种形式有各种不同的方法。   In making the radio waves correspond to each sound in turn ,messages are carried from a broadcasting station to a receiving set.   使无线电波依次对每一个声音作出相应变化时,信息就由广播电台传递到接收机。

这是我喜欢这部电影的原因:它鼓励人们去维护人的尊严,去体会生活的美,而且最重要的是保持希望永远。他曾经是天生的,那就是死。每个人都是一样的。唯一不同的是忙着活,或者忙着死。电影告诉我们,虽然人只能活一次,但是如果他保持信心,希望好好地活,一次也就足够了。信念是能感觉光在黎明前的黑暗中的鸟,希望这个世界能提供的主要的幸福,和生命应该充满鸟儿的歌声和希望带来的快乐。”那是什么呢?这是心灵的战栗,内心的歌唱,人的灵魂和对自由的渴望飞翔。”在整体来说,除了脚本的弱点和不可信(超过两个),性能均强,如果在点一点二维,时代感的艺术方向彻底而低调,托马斯纽曼的成绩很好的支持,是情感的东西不太强烈或甜蜜。对一个监狱戏剧,暴力不是打起来特别,但这不是自由的威利,要么。出于好奇,肖申克是一个好的夜晚,俗话说。如果概念不抓你从一开始,该文件将抓住你的眼睛。在大多数情况下,令人满意的选项是通常的选择,一个会让观众高兴。虽然这是一个愉快的直接经验,副作用是真正的惊喜的缺乏使得它不持久的比你希望的

int数据打出来是随机数值

java中生成随机数的方式之1:利用 java.util.Random 工具类可以生成随机数,以jdk1.8为例1、Random对象的创建我们先来看下Random的构造方法// 无参构造public Random(){}// 带参构造public Random(long seed){}我们来看一下它的相关源码:/*** Creates a new random number generator. This constructor sets* the seed of the random number generator to a value very likely* to be distinct from any other invocation of this constructor.*/public Random() {this(seedUniquifier() ^ System.nanoTime());}/*** Creates a new random number generator using a single {@code long} seed.* The seed is the initial value of the internal state of the pseudorandom* number generator which is maintained by method {@link #next}.**The invocation {@code new Random(seed)} is equivalent to:*{@code* Random rnd = new Random();* rnd.setSeed(seed);}** @param seed the initial seed* @see #setSeed(long)*/public Random(long seed) {if (getClass() == Random.class)this.seed = new AtomicLong(initialScramble(seed));else {// subclass might have overriden setSeedthis.seed = new AtomicLong();setSeed(seed);}}从源码中我们可以获取的信息有:对于无参构造方法,Random() 在创建对象时,会生成一个随机数作为种子,利用这个种子生成新的随机数。而这个随机数是当前系统时间的纳秒值和另外一个长整型毫秒值的异或运算的结果【this(seedUniquifier() ^ System.nanoTime())】对于有参构造方法,根据方法上的注释,我们发现方式1:Random rd1 = new Random(10);等价于以下语法方式2:Random rd2 = new Random();rd.nextInt(10);但是,实际测试中,并没有这么简单,请参照第3标题下的内容。2、Random对象的生成随机数的相关方法Random类中,生成随机整数的相关方法有:/*** ...* @return the next pseudorandom, uniformly distributed {@code int}* value from this random number generator"s sequence*/public int nextInt() {return next(32);}/*** ...* @param bound the upper bound (exclusive). Must be positive.* @return the next pseudorandom, uniformly distributed {@code int}* value between zero (inclusive) and {@code bound} (exclusive)* from this random number generator"s sequence* @throws IllegalArgumentException if bound is not positive* @since 1.2*/public int nextInt(int bound) {if (bound <= 0)throw new IllegalArgumentException(BadBound);int r = next(31);int m = bound - 1;if ((bound & m) == 0) // i.e., bound is a power of 2r = (int)((bound * (long)r) >> 31);else {for (int u = r;u - (r = u % bound) + m < 0;u = next(31));}return r;}nextInt() 和 nextInt(int) 这两个方法都可以用来生成随机数。但是它们两个方法的区别在于假设 Random ra = new Random();ra.nextInt() 会生成一个任意的 随机整数(包括正数和负数)ra.nextInt(int) 会生成一个 [0,9] 之间的任意一个整数测试代码如下:public class TestRandomConstructor {public static void main(String[] args) {System.out.println("========================= nextInt(10) ================");Random rd1 = new Random();for (int i = 0; i < 20; i++) {System.out.println(rd1.nextInt(10));}System.out.println("========================= nextInt() ================");for (int i = 0; i < 20; i++) {System.out.println(rd1.nextInt());}}}测试结果:========================= nextInt(10) ================7781827610...

跪求蝴蝶梦的复述和评论!!!!英文的谢谢了~~~~~~~~~~

  复述(summary)如下:  A shy ladies" companion, staying in Monte Carlo with her stuffy employer, meets the wealthy Maxim de Winter. She and Max fall in love, marry and return to Manderlay, his large country estate in Cornwall. Max is still troubled by the death of his first wife, Rebecca, in a boating accident the year before. The second Mrs. de Winter clashes with the housekeeper, Mrs. Danvers, and discovers that Rebecca still has a strange hold on everyone at Manderlay.  还有一个:  Maxim de Winter, still troubled by the death of his first wife Rebecca, falls in love with a shy ladies" companion. They get married, but the second Mrs. de Winter discovers that Rebecca still has a strong hold on everyone in the house, particularly on Mrs. Denvers, the housekeeper, who begins driving the young wife to madness.  评论(comments)如下:1.a brief one比较简洁的^_^  A stylishly directed and photographed film that examines a number of themes, such a deception, death and depression, and explores well the emotions of its characters. It is rare to find a film like this, as it tackles various genres, ranging from being a romance to a mystery to a drama to even a comedy at times, and all without seeming pretentious. The cast is truly magnificent. Judith Anderson is a stunner is a quiet but sinister role, and George Sanders is even more impressive in lively but also sinister performance. Laurence Olivier and Joan Fontaine are perfect for their roles too. The film won Academy Awards for Best Picture and Best Cinematography quite deservingly – this is one of the best films Hollywood has ever produced.  2.一个比较详细的^_^  《 What Atmospheric Gothic-horror Should Be》  Alfred Hitchcock was and is still the undisputed Master of Suspense, and there is a lot of that here in his foray into Gothic horror, as the mystery surrounding the unseen yet omnipresent Rebecca will engage the viewer from its dreamy start to its bleak conclusion. This is exactly what atmospheric is supposed to be about, and in black and white, it shines. This is also what Gothic horror is in essence, and many have imitated yet come up short, most notably M. Night Shyamalan who, in trying to go for a shock twist and purported "atmosphere" only creates a bad aftertaste and a hangover the size of Mount Everest. This is, essentially, Hitchcock"s first true masterpiece.  Not one performance rings false, not to the novel or to their respective interpretations. Lawrence Olivier, quite possibly one of the greatest actors that ever lived, portrays a broken man who still lives haunted by the past as he himself were still living in that unending hell. Judith Anderson embodies one of the most coldly sadistic figures in cinema history, her smooth and elegant truculence only exceeded by Anthony Hopkins" rendition of Dr. Hannibal Lecter. One can"t seem to understand the way she wallows in her dead mistresses" clearly perverse nature, but that exactly she does, right down to her own end. George Sanders does what he does best: sneer, smirk, and spit line after line of practiced venom, and would be honored 10 years later in ALL ABOUT EVE. Gladys Cooper, still striking in her 50s, plays into her casual cattiness which means no harm, although her rendition of Beatrice Lacy is a little subdued from the novel"s version.  And then there is Joan Fontaine. Not one of the best actresses on film, yet here, playing a role that evolves beautifully from a frightened, weak girl who is put into a situation she does not understand and who turns right at the point of losing it into a much more mature, strong woman capable of holding her own, she carries the weight of the entire drama and comes forth with flying colors. While I would have preferred Anne Baxter who would have been the exact right age for this role, Fontaine exudes so much restraint and nervousness about her character (partially to blame Olivier"s treatment of her and Hitchcock"s telling her the entire cast hated her), it"s almost a relief when she finally decides to confront Olivier about what it the secret of Manderley. Not many roles require such a change and not many actresses would sink her teeth into a part that requires being put-upon until she can"t stand no more, and this is one beautiful performance.  A movie that should have won more Oscars that year, REBECCA has since grown in stature and proved that a film need not trophies to be Timeless and Great.  再补充几个^_^comments  《the first Hitchcock masterpiece》  "Rebecca" was the first Hitchcock film I ever saw, and I was mesmerized by it from the start, convinced that I had to see more of the director"s work. It richly deserved the Oscar it received, but it"s a real puzzle that the Academy saw fit to withhold a best director award for Hitch. Would one possibly give an award to a work by Picasso and not to Picasso himself?  "Rebecca" was the first of the director"s American-made films, and it shows. It"s quite different from his earlier British-made films, such as "Young and Innocent" and even "The Lady Vanishes," which somehow seem more amateurish by comparison. (I know little of the British cinema of that era, but it"s difficult not to conclude that Hollywood was better at producing more sophisticated efforts.) I would even judge "Rebecca" the best of his films of the early 1940s, with the possible exception of "Shadow of a Doubt." It is true, of course, that much of this film has become cliché (remember the spoofs on the old "Carol Burnette Show"!), but it still weathers the decades very well. The acting is uniformly excellent. Olivier is the hardened Maxim de Winter, untitled lord of Manderly, trying to forget the past and given to unexpected bouts of anger and coldheartedness. Fontaine is perfect as the unnamed mousy heroine, innocent yet deeply in love, still carrying with her the aura of an awkward schoolgirl. Even character actor Nigel Bruce, best known for his role in the Sherlock Holmes films, makes an appearance and plays, in effect, Nigel Bruce!  But it is Judith Anderson"s role as Mrs. Danvers that viewers are likely to remember best. Her presence is as dark and foreboding as that of the deceased Rebecca herself, and Fontaine is evidently cowed by her icy stare and unnervingly formal manner. The dynamics between the two actresses are wonderful. Who could fail to empathize with Fontaine"s unenviable position as, in effect, the new employer of such an intimidating personage? On the other hand, Olivier seems quite unfearful of Anderson, despite her representing so much of the past he is trying to block out. This part of the plot (even in the book) never made much sense to me and is unconvincing.  As far as I know, this film marked Hitch"s first collaboration with composer Franz Waxman, whose haunting score makes it all the more memorable. Waxman"s scores are perhaps less obviously cinematic than those of the incomparable Bernard Herrmann, who would score Hitch"s films from 1955 to 1966. Contrast the score for "Rebecca" to Herrmann"s music for "Citizen Kane" the following year, and you"ll immediately hear the difference. Waxman"s is more symphonic in the central European style reflective of his own birth and upbringing. Yet it is worth recalling that scoring films was still a new art at this time, and both Waxman and Herrmann were pioneers.  Finally, one has to mention the cinematography, which is magnificent. Technically "Rebecca" might have been filmed in colour, which was newly available in 1940. ("Gone with the Wind" was filmed entirely in colour the previous year, while "The Wizzard of Oz" and "The Women" had colour scenes.) But colour would have diminished its impact. The suspense and the ominous sense of impending doom could only have been communicated through the medium of black-and-white and the deft use of light and shade which it affords.  In one respect, of course, "Rebecca" is not a typical Hitchcock film. There is no fleeing innocent trying to clear his name of a crime he did not commit. Surprisingly, there isn"t even a murder, although its absence was apparently imposed by the Hayes Code and is certainly foreign to Daphne du Maurier"s original novel. Some have said that there is more Selznick than Hitchcock in this film, and perhaps there"s something to that. Still, if the collaborative effort between the two was not exactly amiable, it was nevertheless successful.  In short, this is the first in a string of Hitchcock masterpieces.  《Haunting atmospheric treasure SPOILER ALERT》It seems almost superfluous to add to the many laudatory comments this movie has received on this site, but I feel a need to lay some tribute at the altar of this wonderful piece of classic cinema.  If you haven"t seen the movie, there may be a couple of SPOILERS in this review, but hopefully also some new insights in compensation.  As many have noted, the cast is uniformly excellent: the annoying social snob Edith Van Hopper(Florence Bates), Gladys Cooper"s kind, sisterly Beatrice, the eerie Mrs. Danvers of Judith Anderson, Olivier"s distracted yet explosive Maxim, George Sanders" snide, oily Favell and especially the oft-times underrated second (but unnamed) Mrs. DeWinter of Joan Fontaine.  Although not entirely faithful to the Daphne Du Maurier novel, the screen adaptation preserves the haunting ambiance of Du Maurier"s work. Rebecca, though never seen, is clearly the central character, but we learn about her all through indirection in the dialogue of the other characters. We are allowed to create her piece by piece in our own minds, which just adds to the engrossing, I-can"t-stop-watching, thrust of the movie.  The character who actually tells us the most about the real Rebecca is Mrs. Danvers. The erotic attachment of this character to Rebecca is subtle, yet unmistakable. The wonderful scene in which Judith Anderson shows Rebecca"s bedroom to Joan Fontaine is breathtaking in its suggestiveness. The West Wing, "the only room that looks down across the lawn to the sea" has become Mrs. Danvers" private temple to Rebecca. Her loving preservation of Rebecca"s possessions, her sensual handling of Rebecca"s underclothes, of her diaphanous negligee, of her glamorous furs and then Anderson"s almost hypnotic miming of brushing Rebecca"s hair as Fontaine sits at Rebecca"s dressing table all make this scene an unforgettable sequence. Anderson"s acting is absolutely miraculous. She achieves her character with hardly ever a change in her affect, except where a very slight contrasting up tick in energy transforms her in the West Wing scene and in the scene where she coolly suggests that Fontaine leave-by means of a precipitous drop out of the window onto the rocks. It is a performance which I doubt could ever be duplicated.  As we later learn of Rebecca"s moral character, it also seems that Mrs. Danvers was as much in love with Rebecca"s corruption as she was with the woman herself. "Danny" in a way becomes the embodiment of Rebecca"s cold malevolence which still lingers in the mansion.  Joan Fontaine could hardly have been better. She, of all the characters, evolves through the movie. She moves in a seamless line from the pitiful, beleaguered companion of Mrs. Van Hopper to her drowned rat arrival at Manderley to the self-assured and supportive wife Maxim wanted and needed. What I found fascinating about this transformation is the imaginative skill of the costume designer. At the beginning, Fontaine"s shy little character is dressed like she made terrible selections at a Macy"s basement sale. Later as she tries to fill the role of the "great lady" she believed Rebecca to have been, her clothes always appear too big and totally out of character. Note the black evening dress with the absurdly large flowers across the front and especially the overwhelmingly outsized Garden Party gown she tries to wear to the costume ball. After she learns the truth about Rebecca from Maxim, discovering that he actually loves her as much as he hated Rebecca, Fontaine"s costumes become trim, conservative and tasteful, befitting the genuine, grown-up woman she has become.  Fittingly, the final scene belongs to Anderson-the frustrated woman robbed of her goddess--who brings the movie to a thundering operatic finish.  Although Selznick and Hitchcock repeatedly clashed over this move, it remains a deathless tribute to both men. This movie never loses its fascination and bears repeated watching, each time weaving its wonderful spell anew. It is a must-see, again and again, classic.  希望对你有所帮助^_^

请帮忙翻译一下这篇文章,关于热力流体3的(语句要通顺)

液体将煮沸的压力称它的汽压。 这压力是温度的作用(汽压增加以温度)。 在这上下文我们通常考虑煮沸发生的温度。 例如,水煮沸在100oC以海平面大气压(1 atm吸收)。 然而,根据汽压,我们可以说通过增加温度水在海水平对100 oC,我们增加汽压对它与大气压的点(1 atm吸收)是相等的,因此煮沸发生。 形象化煮沸在水中可能也发生在温度在100oC之下的是容易的,如果压力在水中减少到它的汽压。 例如,水汽压在10oC是0。01 atm。 所以,如果压力在水之内在那个温度减少到那价值,水煮沸。 这样煮沸在流动的液体经常发生,例如在泵浦的吸边。 当这样煮沸在流动的液体时发生,蒸气泡影在高顺流压力的地区开始生长在非常低pressre的地方地区然后崩溃。 这种现象叫作为气蚀压缩性和体积弹性模量: 所有材料,固体,液体或气体,是否是可压缩的, i。e. 当力量在它的表面,一致地被施加被测量的大量的容量v将减少到V - dV。 如果表面每单位面积力量增加从p到p + dp,压力的容量之间的变动和变动的关系依靠材料的体积弹性模量。 体积弹性模量(k) = (在压力)/(上的变化容量张力) 容量张力是体积变化原始的容量划分的。 所以, (体积变化)/(原始的容量) = (在压力)/(上的变化体积弹性模量) i.e.- dV/V = dp/K 当压力增加,负号为dV表明容量减退。在极限,作为dp趋向到0,K = - V dp/dV à 1 考虑物质单位质量, V = 1/r à 2

三星note20spen用处大吗

note20spen用处有时候截图想打点马赛克,画圈圈做批注,有了spen就很方便。手机QQ好友私聊里面有个“涂鸦”功能,可以用spen画动画表情,挺有意思。.spen用来修图、剪视频片段,相比手指更精确更方便。spen可以用来截视频制作成gif动画。可以将spen悬浮在英语或者其它语言单词上,显示翻译。按着spen的侧键,可以选中某些地方不给复制的文字,从而进行复制。spen配合“微软数学”应用,可以识别墨迹公式,进行计算数学式,方程组、微积分都能算。spen可以在OneNote中使用,修改用Surface等二合一电脑书写的墨迹。虽然不是每个人都会画画,但是配合“概念画板”等应用,可以导入图片,新建一个图层,在新图层上描画。然后隐藏掉原图的图层,一幅画诞生。spen可以书写动态墨迹文字,生成gif或者视频,用了送节日祝福或者表白(划掉)挺好。spen可以在录制视频的时候给人面部、头部画点装饰,给你女朋友(不存在)录像画个兔子耳朵什么的怎么样?
