Kissing number problem

EditWatch this page

In geometry, a kissing number is defined as the number of non-overlapping unit spheres that can be arranged such that they each touch another given unit sphere. For a lattice packing the kissing number is the same for every sphere, but for an arbitrary sphere packing the kissing number may vary from one sphere to another. Other names for kissing number that have been used are Newton number (after the originator of the problem), andcontact number.

In general, the kissing number problem seeks the maximum possible kissing number for n-dimensional spheres in (n + 1)-dimensionalEuclidean space. Ordinary spheres correspond to two-dimensional closed surfaces in three-dimensional space.

Finding the kissing number when centers of spheres are confined to a line (the one-dimensional case) or a plane (two-dimensional case) is trivial. Proving a solution to the three-dimensional case, despite being easy to conceptualise and model in the physical world, eluded mathematicians until the mid-20th century.[1][2] Solutions in higher dimensions are considerably more challenging, and only a handful of cases have been solved exactly. For others investigations have determined upper and lower bounds, but not exact solutions.[3]

fresh红茶面膜还是黑茶面膜好用吗-fresh红茶和黑茶面膜的区别

对于fresh红茶面膜和黑茶面膜,它们各有千秋,具体看个人需求和肤质而定。我们来看看fresh红茶面膜。这款面膜采用了红茶作为主要成分,富含多种营养物质,比如茶多酚、维生素C等,可以有效地滋润肌肤、提亮肤色、抗氧化等。fresh红茶面膜还添加了珍珠粉和花瓣等成分,能够深层清洁毛孔、收缩毛孔、去除角质等。如果你的皮肤需要一款清新、滋润的面膜,并且毛孔粗大或角质层厚重,那么fresh红茶面膜会是一个不错的选择。接下来是黑茶面膜。黑茶作为一种发酵程度较高的茶叶,具有很好的抗氧化功效,并且富含多种维生素和矿物质。黑茶面膜则能够有效地滋润肌肤、收缩毛孔、改善肤色暗沉等问题。黑茶还具有一定的抗菌作用,对于油性肌肤或痘痘肌肤也有一定的效果。如果你的皮肤需要一款具有抗氧化、滋润、收缩毛孔等多重功效的面膜,那么黑茶面膜也是不错的选择。fresh红茶面膜和黑茶面膜都是非常不错的产品,具体看个人需求而定。如果你需要深层清洁、去除角质等功效,可以选择fresh红茶面膜;如果你需要抗氧化、滋润、收缩毛孔等多重功效,可以选择黑茶面膜。在使用面膜之前,还要注意肤质问题,以及对于自己的皮肤是否过敏等方面进行考虑。作为美容师,我还想推荐一款产品给大家。森林哲学精华面膜是一款非常好用的产品,它采用了多种天然植物精华成分,能够深层滋润肌肤、提亮肤色、紧致毛孔等。这款面膜非常受到消费者喜欢和好评,如果你还没有尝试过,可以考虑一下哦!

The deeper that sorrow carves into your being.   The more joy you can contain.   Is not the cup that hold your wine the very cup   That was burned in the potteru2019s oven?   And is not the lute that soothes your spirit,   The very wood that was hollowed with knives?   除此之外,又当如何?   镌刻在你们身上的忧伤愈深,你们能盛装的欢乐愈多。   斟满了美酒的杯盏,难道不是曾在陶工炉火中锻造的杯盏吗?   When you are joyous, look deep into your heart and   You shall find it is only that which has given   You sorrow that is giving you joy.   When you are sorrowful look again in your heart,   And you shall see that in truth you are weeping for   That which has been your delight.   当你们快乐时,审视自己的内心,   你们会发现曾经的忧伤如今却让你们快乐。   当你们忧伤时,再次审视自己的内心,   你们会发现曾经的快乐如今却让你们流泪。   Some of you say, “Nay, sorrow is the greater.”   But I say unto you, they are inseparable.   Together they come, and when one sits alone with you at your board,   Remember that the other is asleep upon your bed.   你们中有些人说:“欢乐胜于忧伤。”   另一些人则说:“不,忧伤更伟大。”   但我要说,他们是相辅相成的。   它们一同降临,当其中一个单独与你同坐时,   记住另一个正在你的床上安歇。   Verily you are suspended like scales   Between your sorrow and your joy.   Only when you are empty are you at standstill and balanced.   When the treasure-keeper lifts you to weigh   His gold and his silver, needs must your   Joy or your sorrow rise or fall.   的确,你们就像在忧伤与欢乐之间摇摆不定的天平。   只有当你们彻底空虚时,你们才能平衡稳定。   把你浮沉不定的快乐和悲伤都留给   那用你来称量金银的守财奴吧。   关于悲伤的英文诗歌篇3   一个忧伤的孩子 A Sad Child   Youu2019re sad because youu2019re sad.

英语翻译

The first man to approach flying on a scientific basis was an Englishman who lived during the thirteenth century. 第一个真正意义上飞行的人是一个英国人,生活在13世纪。He looked at the air above us as a sea, and he believed that a balloon could float on the air just as a boat did on water. 他视我们头顶上的蓝天为海洋,并且他相信气球可以像船在水面上航行一样,在天空上飞行。Almost four hundred years later, an Italian priest applied his principle of air flight. 在近400年后,一位意大利的牧师应用了他的空中飞行的理论。He designed a boat, which would be held in the air by four hollow spheres. 他设计了一只船,可以由四个中空的气球带起。Each of the four balls was to be 20 feet in diameter and made of very thin copper. 每一个气球的直径都达到20英尺,用非常薄的铜片制成。But his boat was never built since it was not possible to make spheres of such thin metal and such size in those days.但他的船并没有做成,因为在当时根本不可能用如此薄的金属制造气球,也不可能造出如此尺寸的气球。

游戏建模zbrush雕刻技巧有哪些?

【导语】游戏建模zbrush雕刻技巧有5个,ZBrush的应用范围比较广泛,假如你已经忘记它还是一种3D有机雕刻解决方案的话,这也是可以原谅的,很多人都使用ZBrush制作纹理、创建硬表面模型、三维建模等,下面我们就来一起看看游戏建模zbrush雕刻技巧吧。1、自定义用于界面ZBrush其中一个优势在于它的灵活性,能够让你以一种你觉得最适合你的风格和工作流的方式获得相同的结果,这就延伸到用户界面了,用户界面可以以微妙的方式进行自定义,比如使用自定义菜单和弹出窗口,更改用户界面颜色,创建完全定制的用户界面,享用更多高级选项,点击Preferences > Config > Enable Customise,打开自定义模式,此时可以重新排列和修改用户界面,通常只需改变用户界面的颜色,布局保留默认布局。2、骨骼原则自然界的一切物质生长都有迹可循,包括其如何发育、生长、移动、呼吸和饮食,要想准确地再现某个生物,尽可能多地理解它的骨骼很有必要。不管你是在绘画、拍照还是简单地学习周围事物,关于骨骼知道得越多,你的作品就越接近现实。3、骨骼和肌肉进一步研究骨骼,是特别专注于骨骼和肌肉的一种好方法,其中一个比较好的实践是使用ZSpheres(Z球)创建核心骨骼,然后在生物体内加入主要骨头,接着开始分层堆放正确的肌肉群。4、植物与植被植物和植被与肉质生物一样,也遵循一定的规则,随处可见重复的树叶模式和特殊方式的分支,通过将新部件DynaMesh到模型中,使用Radial Symmetry这样的工具,不费什么力气就可以创建奇怪且奇妙的植物生命。5、使用ZSpheres操作Transpose工具更常用于在ZBrush中给物体摆姿势,但是注意,也可以使用ZSpheres操作单一和多个子工具,由于它是ZBrush中给物体摆姿势的一种老方法,新用户可能不太了解,但它一直是一种很强大的工具。从单一的ZSphere开始,依次点击Tool > Rigging > Select Mesh,选择你想操作的网格然后开始使用ZSpheres构建骨骼,跟在其他3d应用程序(如Maya和Softimage)中放置关节类似,当你对操作结果感到满意时,点击Tool > Rigging > Bind Mesh,接下来就可以根据需求自由给网格摆姿势了。以上就是游戏建模zbrush雕刻技巧的相关介绍,学会了更多的技巧,对于我们进行游戏建模是很有帮助的,希望大学生们能够赶快学习起来。

新概念第三册自学导读 Lessons18

Notes on the text课文注释 1 The idea that… is mistaken. 此处that引导的从句作idea的同位语。 2 take no interest in…,作“对……不感兴趣”解。 3 cannot have failed to notice, 不至于没注意到。 “cannot+have+过去分词”表示对于过去的事所作的不肯定的推测。 4 move in response to a gust of wind,随风飘荡。 in response(to)作“回答"、“响应”、“作出反应”讲。此处是“(展品)随风而动”的意思。 5 be familiar to…是“为……所熟悉”的意思。 6 Lined up against the wall, 靠墙排列着。 7 like traffic lights which have gone mad, 就像失去控制的红绿灯一样。 go mad作“发疯”、“发狂”讲。 8 on and off(亦作 off and on)作“断断续续地”、“有时”讲。 9 These peculiar forms not only seemed designed…,其中seemed是系动词,seemed designed 作用与were designed是一样的。 参考译文 现代雕塑不再使我们感到惊讶了。那种认为现代艺术只能在博物馆里才能看到的观点是错误的。即使是对艺术不感兴趣的人也不会不注意到在公共场所展示的现代艺术品。公园里、大楼和商店外竖立着的奇形怪状的雕塑,对这些,我们已经司空见惯了。有些所谓的“现代”艺术品在那里已经陈列了近80年了。 尽管如此,最近举办的一次现代雕塑展览还是使一些人(包括我在内)大吃了一惊。走进展厅首先看到的是一张告示,上面写着:“切勿触摸展品,某些展品有危险!”展品都是些活动的雕塑。人们所熟悉的是悬挂在天花板上、造型奇特、随风飘荡的雕塑品。这些展品却使人大开眼界。靠墙排列着许多细长的电线,而电线又连着金属球。金属球经过磁化,互相之间不停地相互吸引或相互排斥。展厅中央是装有彩色灯泡的许多高高的构件,灯泡一刻不停地闪烁着,就像失去了控制的红绿灯。小黑盒子里迸出火花,红色灯泡发怒似地忽明忽暗。这儿倒像是在展览古老的电子设备。好像设计这些奇形怪状的展品不仅是为了给人感情上的强烈刺激,而且还想给人以电击似的! Summary writing 摘要写作 In not more than 80 words describe what the writer saw from the moment he entered the art gallery. Do not include anything that is not in the last paragraph.

Use the following information to write the Purpose: thank him for invitation----looking forward to meeting him again soon----particularly interested in exhibition----why----where you will meet your friend: time and place.

鸡蛋能不能在糖水中浮起来?

鸡蛋可以在糖水中浮起来。鸡蛋可以在糖水中浮起来,水中加白糖鸡蛋会浮起来,这是因为在水中加入了白糖之后,糖水的浓度会上升,所导致的结果就是鸡蛋会自然的浮上来,这个原理跟往水中加盐的道理是一样的。当鸡蛋在水中的介质密度越大,它所受到的浮力也就越大。鸡蛋的早期发育过程1、鸡属卵生动物,胚胎在卵中发育。受精后,合子在输卵管中要经过24~27小时的发育。在如此长的时间内,合子已发育到了囊胚阶段甚至原肠胚早期阶段。此时在卵黄上可见略大白色圆盘称为胚盘,其中包含了成百上千个细胞,因此这时的鸡蛋,已不再是一个细胞了。2、产蛋母鸡如果没有接受雄鸡交配,其所产蛋的卵子停留在减数第二次分裂的中期,因此,这样的每枚鸡蛋(严格地说是蛋黄)可以看成一个很大的细胞。

糖水不等式的证明可以从以下几个方面来看:1、从生活常识理解小文有一杯糖水,(重a克,里面有b克的糖,这份糖水的浓度就是糖/糖水=b/a。) 小文跟妈妈说,这糖水太淡了,不够甜,妈妈拿出了c克白糖,放进了小文的杯子里。(现在糖水重 a+c,里面的糖为b+c,浓度变为(b+c)/(a+c)) 小文拿起杯子一尝,果然比原来甜了。就这么一个简单的场景,其实就得出了这个糖水不等式。 原来的浓度:b/a < 加糖后的浓度 (b+c)/(a+c)。当然,结论还可以推广一下,譬如用淡的糖水+浓的糖水得到甜度中等的糖水。2、从斜率理解。b/a 是浓度,也代表点(a,b)与原点连线的斜率,因为限定b<a(最甜就是纯糖了,浓度100%),所以直线一定在y=x下面(第一象限)。随便举个例子,B(5,1)点的横坐标,纵坐标都加上5,得到 d(10,6),很明显DO的斜率大于原来BO的斜率,即浓度变大。3、应用千万不要小看这个简单的糖水不等式,在高中的不等式证明的时候巧妙应用糖水不等式,可以实现不等式的缩放,将证明极大简化。不等式的缩放是一种艺术。

氢化铝锂的化学性质

溶解度氢化铝锂可溶于多种醚溶液中,不过,由于杂质的催化作用,氢化铝锂可能会自动分解,但是在四氢呋喃中表现得更稳定,因此虽然在四氢呋喃的溶解度较低,相比乙醚,四氢呋喃应该是更好的溶剂。 氢化铝锂在常温下是亚稳的。在长时间的贮存中,氢化铝锂会分解成Li3AlH6和LiH。这一过程可以通过钛、铁、钒等助催化元素来加速。当加热氢化铝锂时,其反应机理分为3步:3 LiAlH4 → Li3AlH6 + 2 Al + 3 H2 (R1)2 Li3AlH6 → 6 LiH + 2 Al + 3 H2 (R2)2 LiH + 2 Al → 2 LiAl +H2 (R3)R1通常以氢化铝锂的熔化开始,温度范围为150-170℃,接着立即分解为Li3AlH6,但是R1是在低于LiAlH4熔点的情况下进行的。在大约200℃时,Li3AlH6分解成LiH和Al(R2),接着在400℃以上分解成LiAl(R3)。反应R1在实际中是不可逆的,而R3是可逆反应,在500℃时的平衡压强是25千帕。在有适当催化剂的情况下,R1和R2反应可以在常温下发生。 LiAlH4遇水立即发生爆炸性的猛烈反应并放出氢气:LiAlH4 + 2H2O → LiAlO2 + 4H2LiAlH4 + 4H2O → LiOH +Al(OH)3+ 4H2由于放出的氢是定量的,该反应可用来测定样品中氢化铝锂的含量。为了防止反应过于剧烈,常加入一些二恶烷、乙二醇二甲醚或四氢呋喃作为稀释剂。这一反应提供了一个有用的实验室制取氢气的方法。长期暴露在空气中的样品通常会发白,因为样品已经吸收了足够的水分,生成了由氢氧化锂和氢氧化铝组成的白色混合物。 LiAlH4 的乙醚或四氢呋喃溶液能同氨猛烈作用放出氢气:2LiAlH4 + 5NH3 → [LiAlH(NH2)2]2NH+ 6H2当氨的量不足时,发生如下反应:LiAlH4 + 4NH3 → LiAl(NH2)4 + 2H2NH3/LiAlH4比值更小时,则氨中的三个氢都可被取代:LiAlH4 + NH3 → Li[Al(NH2)4] 氢化铝锂几乎可以与所有的卤化物反应生成相应的配位铝氢化物,当配位铝氢化物不稳定时,则分解为相应的氢化物。通式为:nLiAlH4 + MXn → M(AlH4)n + nLiXM(AlH4)n → MHn + nAlH3因此可通过此方法制备很多金属或非金属氢化物,如:2LiAlH4 +ZnI2u2212(u221240℃,乙醚)→ ZnH2 +2AlH3 + 2LiILiAlH4 + 4 NaCl → 4 NaH + LiCl + AlCl3 氢化铝锂可与NaH在四氢呋喃中进行复分解反应,高效的生产氢化铝钠(NaAlH4):LiAlH4 + NaH → NaAlH4 + LiH氢化铝钾(KAlH4)可以用二乙二醇二甲醚作为溶剂,以类似的方式制取:LiAlH4 + KH → KAlH4 + LiH 氢化铝锂可将很多有机化合物还原,实际中常用其乙醚或四氢呋喃溶液。氢化铝锂的还原能力比相关的硼氢化钠更强大,因为Al-H键弱于B-H键。由于存储和使用不方便,工业上常用氢化铝锂的衍生物双(2-甲氧基乙氧基)氢化铝钠(红铝)作为还原剂,但在小规模的工业生产中还是会使用氢化铝锂。能被氢化铝锂还原的官能团主要包括:卤代烷被还原成烷烃。碘代烷反应最快,其次是溴代烷和氯代烷。此反应中一级卤代烷(伯卤代烷)性能较好,所得产物发生构型转化,因此认为该反应是SN2机理。二级卤代烷(仲卤代烷)也可用此法还原,三级卤代烃(叔卤代烷)容易发生消除反应,不适用此法。氢化铝锂只能用于还原醇基在附近的炔烃,不能用于还原简单烯烃和芳香烃。硅卤化物等还原为硅烷,如:LiAlH4 + SiCl4 → SiH4 + LiCl + AlCl3羰基化合物(酰胺除外)被还原为醇,如酯和羧酸都可以被氢化铝锂还原成伯醇。在氢化铝锂还原酯的方法发现之前,一般用布沃-布朗还原反应还原酯,即将煮沸的金属钠-无水醇作为还原剂,但这一反应较难进行。醛和酮也可以被氢化铝锂还原成醇,不过一般使用如NaBH4这类更温和的试剂来还原。α,β-不饱和酮会被还原成烯丙醇。环氧化合物。当环氧化合物被还原时,氢化铝锂试剂会攻击环氧化合物的位阻小的一端,通常会生成仲醇或叔醇。环氧环己烷会被优先还原成a键(直立键)的醇。酰胺和酰亚胺被还原成胺。这类反应一般产率较高,并且用N,N-取代的原料反应比其他要快很多。腈被还原成伯胺。另外,肟、硝基化合物以及烷基叠氮都可以被还原成胺。季铵阳离子可被还原成对应的叔胺。与醇反应生成烷氧基氢化铝锂:LiAlH4 + ROH → LiAl(OR)H3 + H2LiAlH4 + 2ROH → LiAl(OR)2H2 + 2H2LiAlH4 + 3ROH → LiAl(OR)3H + 3H2LiAl(OR)2H2 是将酰胺还原为醛的适宜试剂,LiAl(OC(CH3)3)3H是将酰氯还原为醛的适宜试剂,而利用氢化铝锂不能将酰氯部分还原生成对应的醛,因为氢化铝锂会将后者完全还原为伯醇,因此必须要使用更温和的三叔丁氧基氢化铝锂(LiAl(OC(CH3)3)3H)来还原酰氯。三叔丁氧基氢化铝锂与酰氯的反应比与醛的反应迅速得多,例如在异戊酸中加入氯化亚砜会生成异戊酰氯,这时可利用三叔丁氧基氢化铝锂将异戊酰氯还原为异戊醛,产率能达到65%。

橘子罐装原理是什么

糖水桔子罐头的保藏原理:1、糖分高,使得微生物不能生存。2、密封无氧,有氧微生物无法生存。水果罐头的存储注意事项:第一,不要贮存太久虽然水果罐头的贮存期很长,但也有一定的期限,所以若贮存太久,水果罐头发生变质,如长毛变色,就不要食用,以免发生食物中毒。第二,水果罐头要存放在干燥、阴凉、通风处罐头放在潮湿、闷热的地方,容易生锈且影响质量和贮存寿命;若放在阳光时常照射的地方,水果罐头本身容易起变化;因此要选择干燥、阴凉、通风的地方。第三,要注意生产日期把生产日期接近的水果罐头,放在相近的位置,且日期愈久的要先吃,尽快食用为宜。第四,不必冰在冰箱中水果罐头制作时经过杀菌的步骤,所以不必摆进冰箱,若冰箱中有多余的空间来摆置罐头,则更可延长其贮存寿命。但如饮料、水果罐头为了风味可冰在冰箱中,则更清凉可口。

糖霜形成的原理

挂霜,或者叫糖霜,是炒糖过程中达到的第二种状态。挂霜的原理就是糖的重结晶:糖液经历了糖水状态后,继续加热,随着水分的不断蒸发,糖液的浓度逐渐增大,当糖液的浓度达到临界点之后,糖液就成为了过饱和溶液,这个时候把原料放入锅里均勺裹上糖液,关火,并不断翻拌,随着温度的降低,白糖将以结晶体的形式再次析出,这种现象又称为翻砂或返砂。 这个阶段的糖液适合做挂霜丸子、糖霜花生(就是花生粘)、山楂糖雪球这类菜品。
