说起高分子材料,普通人也许会觉得莫测高深,其实我们身边到处都是它们的身影。
无论是作为食物的蛋白质还是作为织物的棉、毛和蚕丝都是天然高分子材料,就连人体本身,基本上也是由各种生物高分子构成的。我国在开发天然高分子材料方面曾走在世界领先水平。利用竹、棉、麻等纤维等高分子材料造纸是我国古代的四大发明之一。另外,利用桐油与大漆等高分子材料作为油漆、涂料制作漆制品也是我国古代的传统技术。
高分子是由碳、氢、氧、硅、硫等元素组成的分子量足够高的有机化合物。之所以称为高分子,就是因为它的分子量高。常用高分子材料的分子量在几百到几百万之间,高分子量对化合物性质的影响就是使它具有了一定的强度,从而可以作为材料使用。这也是高分子化合物不同于一般化合物之处。又因为高分子化合物一般具有长链结构,每个分子都好像一条长长的线,许多分子纠集在一起,就成了一个扯不开的线团,这就是高分子化合物具有较高强度,可以作为结构材料使用的根本原因。另一方面,人们还可以通过各种手段,用物理的或化学的方法,或者使高分子与其他物质相互作用后产生物理或化学变化,从而使高分子化合物成为能完成特殊功能的功能高分子材料。
功能高分子材料主要包括物理功能高分子材料及化学功能高分子材料。前者如导电高分子、高分子半导体、光导电高分子、压电及热电高分子、磁性高分子、光功能高分子、液晶高分子和信息高分子材料等;后者如反应性高分子、离子交换树脂、高分子分离膜、高分子催化剂、高分子试剂及人工脏器等,此外还有生物功能和医用高分子材料,如生物高分子、模拟器、高分子药物及人工骨材料等。
大致地说,高分子可以分为天然高分子与合成(人工)分子。

可分为以下四类:
1.高分子材料(Polymer Material)
2.无机非金属(inorganic nonmetallic materials)(包括陶瓷材料,半导体材料等)
3.金属(metal)(一般分为铁基金属(黑色金属),非铁基金属(有色金属))
4.复合材料 (Composite materials)(由两种或者更多种材料以恰当的组合方式构成。一般会以一种材料做基体,另一种材料做为增强体

什么叫3C复合铝板
3C复合板是以经过化学处理的涂装铝板为表层材料,用聚乙烯塑料为芯材,在专用铝塑板生产设备上加工而成的复合材料。铝塑复合板本身所具有的独特性能,决定了其广泛用途:它可以用于大楼外墙、帷幕墙板、旧楼改造翻新、室内墙壁及天花板装修、广告招牌、展示台架、净化防尘工程。属于一种新型建筑装饰材料。铝塑复合板(又称铝塑板)作为一种新型装饰材料,自上世纪八十年代末九十年代初从韩到中国,便以其经济性、可选色彩的多样性、便捷的施工方法、优良的加工性能、绝佳的防火性及高贵的品质,迅速受到人们的青睐。在国外,铝塑板的名称有好多种,有叫铝复合板(Aluminum CompositePanels)的;有叫铝复合材料(Aluminum CompositeMaterials)的;在欧洲许多国家称铝塑板为Alucobond,源于铝塑板的一种商标名称。国外生产铝塑板的企业并不是很多,但生产规模都很大。著名的有总部设在瑞士的Alusuisse公司、美国的雷诺兹金属公司、日本三菱公司、韩国大明等。台湾吉祥,大陆的著名企业有江西雅丽泰、华天铝业、上海华源、宁波爱佳建材等。【铝塑板】由性质截然不同的两种材料(金属和非金属)组成,它既保留了原组成材料(金属铝、非金属聚乙烯塑料)的主要特性,又克服了原组成材料的不足,进而获得了众多优异的材料性质,如豪华性、艳丽多彩的装饰性、耐候、耐蚀、耐创击、防火、防潮、隔音、隔热、抗震性;质轻、易加工成型、易搬运安装等特性。因此,被广泛应用于各种建筑装饰上,如天花板、包柱、柜台、家具、电话亭、电梯、店面、广告牌、厂房壁材等,已成为三大幕墙中(天然石材、玻璃幕墙、金属幕墙)金属幕墙的代表,在发达国家,铝塑板还被用于巴士、火车厢的制造、飞机、船舶的隔音材料、设计仪器箱体等。2023-07-27 17:43:041
什么是铝塑板和防火板,有何区别?
格闰科技为您解答:铝塑复合板是以经过化学处理的涂装铝板为表层材料,用聚乙烯塑料为芯材,在专用铝塑板生产设备上加工而成的复合材料。 铝塑复合板本身所具有的独特性能,决定了其广泛用途:它可以用于大楼外墙、帷幕墙板、旧楼改造翻新、室内墙壁及天花板装修、广告招牌、展示台架、净化防尘工程。铝塑复合板在国内已大量使用,属于一种新型建筑装饰材料。防火板又名耐火板,学名为热固性树脂浸渍纸高压层积板,英文缩写为HPL【Decorative High-pressure Laminate】是表面装饰用耐火建材,有丰富的表面色彩,纹路以及特殊的物流性能,广泛用于室内装饰、家具、厨柜、实验室枱面、外墙等领域。根据两者的情况,铝塑板一般用于作为装饰面板使用,而防火板则依其特性,一方面可用于作装饰之用,同时也用于在某些特殊,容易接触到火情的地方,发挥其阻燃作用2023-07-27 17:43:153

头盔材质:ABS 复合材料 玻璃钢 碳纤维各有有什么区别?怎样分辨好坏?
ABS树脂是五大合成树脂之一,其抗冲击性、耐热性、耐低温性、耐化学药品性及电气性能优良,还具有易加工、制品尺寸稳定、表面光泽性好等特点,容易涂装、着色,还可以进行表面喷镀金属、电镀、焊接、热压和粘接等二次加工,广泛应用于机械、汽车、电子电器、仪器仪表、纺织和建筑等工业领域,是一种用途极广的热塑性工程塑料。复合材料(Compositematerials),是由两种或两种以上不同性质的材料,通过物理或化学的方法,在宏观上组成具有新性能的材料。各种材料在性能上互相取长补短,产生协同效应,使复合材料的综合性能优于原组成材料而满足各种不同的要求。复合材料的基体材料分为金属和非金属两大类。金属基体常用的有铝、镁、铜、钛及其合金。非金属基体主要有合成树脂、橡胶、陶瓷、石墨、碳等。增强材料主要有玻璃纤维、碳纤维、硼纤维、芳纶纤维、碳化硅纤维、石棉纤维、晶须、金属丝和硬质细粒等。玻璃钢(FRP)亦称作GRP,即纤维强化塑料,一般指用玻璃纤维增强不饱和聚脂、环氧树脂与酚醛树脂基体。以玻璃纤维或其制品作增强材料的增强塑料,称谓为玻璃纤维增强塑料,或称谓玻璃钢。由于所使用的树脂品种不同,因此有聚酯玻璃钢、环氧玻璃钢、酚醛玻璃钢之称。质轻而硬,不导电,机械强度高,回收利用少,耐腐蚀。可以代替钢材制造机器零件和汽车、船舶外壳等。碳纤维(carbonfiber),顾名思义,它不仅具有碳材料的固有本征特性,又兼具纺织纤维的柔软可加工性,是新一代增强纤维。与传统的玻璃纤维(GF)相比,杨氏模量是其3倍多;它与凯芙拉纤维(KF-49)相比,不仅杨氏模量是其2倍左右,而且在有机溶剂、酸、碱中不溶不胀,耐蚀性出类拔萃。有学者在1981年将PAN基CF浸泡在强碱NaOH溶液中,时间已过去30多年,它至今仍保持纤维形态。区别:碳纤维材料是质强比最高的材料。可以根据断面来区分材料,具体性能好坏无法肉眼区分,只能通过破坏性试验来测试。其中ABS是各向性能一致,玻璃钢、碳纤维复合材料各向异性,纤维方向的抗拉强度最高。2023-07-27 17:44:252

R. China. With tremendous interest in Industrial Engineering, I am writing to apply for acceptance into your Ph.D. graduate program. Education background In 1995, I entered the Nanjing University of Science & Technology (NUST) -- widely considered one of the Chinau2019s best engineering schools. During the following undergraduate study, my academic records kept distinguished among the whole department. I was granted First Class Prize every semester, and my overall GPA(89.5/100) ranked No.1 among 113 students. In 1999, I got the privilege to enter the graduate program waived of the admission test. I selected the Shanghai Jiao Tong University to continue my study for its best reputation on Combinatorial Optimization and Network Scheduling where my research interest lies. At the period of my graduate study, my overall GPA(3.77/4.0) ranked top 5% in the department. In the second semester, I became teacher assistant that is given to talented and matured students only. This year, I won the Acer Scholarship as the one and only candidate in my department, which is the ultimate accolade for distinguished students endowed by my university. Presently, I am preparing my graduation thesis and trying for the honor of Excellent Graduation Thesis. Research experience and academic activity When a sophomore, I joined the Association of AI Enthusiast and began to narrow down my interest for my future research. In 1997, I participated in simulation tool development for the scheduling system in Prof. Wangu2019s lab. With the tool of OpenGL and Matlab, I designed a simulation program for transportation scheduling system. It is now widely used by different research groups in NUST. In 1998, I assumed and fulfilled a sewage analysis & dispose project for Nanjing sewage treatment plant. This was my first practice to convert a laboratory idea to a commercial product. In 1999, I joined the distinguished Professor Yu-Geng Xis research group aiming at Network flow problem solving and Heuristic algorithm research. Soon I was engaged in the FuDan Gene Database Design. My duty was to pick up the useful information among different kinds of gene matching format. Through the comparison and analysis for many heuristic algorithms, I introduced an improved evolutionary algorithm -- Multi-population Genetic Algorithm. By dividing a whole population into several sub-populations, this improved algorithm can effectively prevent GA from local convergence and promote various evolutionary orientations. It proved more efficiently than SGA in experiments, too. In the second semester, I joined the workshop-scheduling research in Shanghai Heavy Duty Tyre plant. The scheduling was designed for the rubber-making process that covered not only discrete but also continuous circumstances. To make a balance point between optimization quality and time cost, I proposed a Dynamic Layered Scheduling method based on hybrid Petri Nets. The practical application showed that the average makespan was shortened by a large scale. I also publicized two papers in core journals with this idea. Recently, I am doing research in the Composite Predict of the Electrical Power system assisted with the technology of Data Mining for Bao Steel. I try to combine the Decision Tree with Receding Optimization to provide a new solution for the Composite Predictive Problem. This project is now under construction.

OLED中LiF薄层的作用机理主要是哪方面呢?越详细越好!谢谢!
LiF的作用应该主要是与Al作用生成Li自由基,增强了器件的电子注入性能,也有人提出是因为LiF的隧穿效应,增加了电子的注入能力,目前比较偏向于前一种说法。2023-07-27 17:46:283
教师面试英文自我介绍范文3篇
一个优秀的 英文 自我介绍 可以帮助教师求职者通过 面试 寻找到一份理想的工作。以下是我精心推荐的一些教师面试英文自我介绍 范文 ,一起来学习下吧! 教师面试英文自我介绍范文(一) General Introduction I am a third year master major in automation at Shanghai Jiao Tong University P. R. China. With tremendous interest in Industrial Engineering I am writing to apply for acceptance into your Ph.D. graduate program. Education background In 1995 I entered the Nanjing University of Science &Technology (NUST) -- widely considered one of the Chinau2019s best engineering schools. During the following undergraduate study my academic records kept distinguished among the whole department. I was granted First Class Prize every semester and my overall GPA(89.5/100) ranked No.1 among 113 students. In 1999 I got the privilege to enter the graduate program waived of the admission test. I selected the Shanghai Jiao Tong University to continue my study for its best reputation on Combinatorial Optimization and Network Scheduling where my research interest lies. At the period of my graduate study my overall GPA(3.77/4.0) ranked top 5% in the department. In the second semester I became teacher assistant that is given to talented and matured students only. This year I won the Acer Scholarship as the one and only candidate in my department which is the ultimate accolade for distinguished students endowed by my university. Presently I am preparing my graduation thesis and trying for the honor of Excel lent Graduation Thesis. Research experience and academic activity When a sophomore I joined the Association of AI Enthusiast and began to narrow down my interest for my future research. In 1997 I participated in simulation tool development for the scheduling system in Prof. Wangu2019s lab. With the tool of OpenGL and Matlab I designed a simulation program for transportation scheduling system. It is now widely used by different research groups in NUST. In 1998 I assumed and fulfilled a sewage analysis &dispose project for Nanjing sewage treatment plant. This was my first practice to convert a laboratory idea to a commercial product. In 1999 I joined the distinguished Professor Yu-Geng Xis research group aiming at Network flow problem solving and Heuristic algorithm research. Soon I was engaged in the FuDan Gene Database Design. My duty was to pick up the useful information among different kinds of gene matching format. Through the comparison and analysis for many heuristic algorithms I introduced an improved evolutionary algorithm -- Multi-population Genetic Algorithm. By dividing a whole population into several sub-populations this improved algorithm can effectively prevent GA from local convergence and promote various evolutionary orientations. It proved more efficiently than SGA in experiments too. In the second semester I joined the workshop-scheduling research in Shanghai Heavy Duty Tyre plant. The scheduling was designed for the rubber-making process that covered not only discrete but also continuous circumstances. To make a balance point between optimization quality and time cost I proposed a Dynamic layered Scheduling method based on hybrid Petri Nets. The practical application showed that the average makespan was shortened by a large scale. I also publicized two papers in core journals with this idea. Recently I am doing research in the Composite Predict of the Electrical Power system assisted with the technology of Data Mining for Bao Steel. I try to combine the Decision Tree with Receding Optimization to provide a new solution for the Composite Predictive Problem. This project is now under construction. Besides In July 2000 I got the opportunity to give a lecture in English in Asia Control Conference (ASCC) which is one of the top-level conferences among the world in the area of control and automation.

求初三中学生英语演讲的自我介绍
Hello, teachers and pupils. Nice to meet you. My Chinese name isXXX, and my English name is XXX. I"m XX years old. I like to study . I like Maths best. Also I like reading, writing, listening to music, playing the piano and playing computer. All the classmates call me “the king of computer”. I can make beautiful pictures with Photoshop, and I can make the animations with Flash. I like sports. I like playing football, basketball and swimming. I like F1 best. I"m one of the Massa"s fans. I think Massa can drive the car fast. He is a good driver. I like to eat, so I"m fat. Do you think so? I"m tall. Now I"m 1.65 meters tall. Today it"s my first to come to Jincai Middle School. I thinks it"s beautiful, I like it very much. And I think it"s my pleasure to study here in the future. Hello everyone~ Unfortunately it"s my turn to introduce myself. This is nearly my first time to talk before such a large audience ,so I feel a little nervous , I hope you will not laugh at me. My English is not very good ,especially my spoken english. And i always couldn"t exprss myself very well in some other aspects. Speaking of my English learning, though i think i don"t have any gift in it , i am not very poor at it. I don"t like the education system in china now ,i find it make each of us feel so tired .and i think most parents and students misunderstand the meaning of study. You know ,i don"t want to be a bookworm. Sometimes i hope i can grow up quickly, but maybe i will want to be a child again after I really become an adult. Because of my personal character ,i am quite interested in computer ,but I am not lost in playing computer games. After lots of experience in using in, i"ve learned a large amount of knowledge about it. So i "d like to be a software engineer in the future. I guess it doesn"t need much ability of speaking. It just suit me. Moreover ,nowadays this career is in a big demand in the society .if i couldn"t study well in some major subjects ,i would choose to be a software engineer~ That"s all~ thank you! Hello, My name is **,郭村now in secondary school. I am a bit sub-high, 1 meter 69, ranked first in class 7. I round face, the pair of dark eyes, short hair,嵌着pair浓眉大眼, long in both sides of both ears, a mouth set in the central face, a mouth in particular can say, as long as the one to say that a hour no problem. A mouth that is above the nose. I am a smiling face every day, even if there is trouble I will not say so, on the whole is still relatively cool. I, humor, tolerance. I always like to watch other people do not look extremely angry, I think other people"s laughter is the world"s most beautiful scenery. So every day, I will become a pistachio, as much as possible to bring them joy. "Broader than the earth is the ocean, than the ocean is wide sky, the sky over the broad people"s hearts." Tolerance so narrow-minded capacity of rivers, so treat someone else"s fault, I have to pay in one joke went. I do own. Mr. Qi said; "I learn from Health, it seems I have to die." Get out of the framework of our predecessors, naturally, will not have their own world. When the bubble pop novel, I felt at that time in a waste of time, when the popular online games, I feel it is in the wasted youth. To do themselves, to see the real me,十二分show confidence in telling myself: "I am what I am, what with him?!" Throw away the vanity of those people who, carving, showed their trump card, and to pursue their personality, to do my own, the best! I am positive. I was a little sand, but unwilling to lag behind, and his inaction commonplace. I would like to make the lives of chiefs, to do a pearl tears immortal. Long Way much of its repair Come,吾将up and down while the search. I"m looking forward to the direction of Art Tower, culture top, the cause of Xiamen, on the edge of celebration and live in this era of flowers, leaving the footsteps of his down-to-earth sound to the United States and love the world洒向... ... This is what I, as long as they see me, and I always laugh, I will warm you and say hello. Said so much, you still do not understand how me. Ha ha. To understand it you know me, I also like you to make friends!大家好,我叫** ,现在在郭村中学学习。我个子有点高,1米69,在班里排第7个。我圆圆的脸蛋上,一双乌黑的眼睛,短头发,嵌着一双浓眉大眼,两只耳朵长在两旁,一张嘴镶嵌在脸蛋中央,一张嘴特别能说,只要一说起来,说上一个小时也没问题。一张嘴的上面就是鼻子。我每天都有一张笑脸,即使有烦恼我也不会说出来,总的来说还是比较帅的。 我,幽默宽容。我向来不喜欢看别人满面怒容的样子,我认为他人的笑才是天下最美的风景。所以每天,我都会变成一颗开心果,尽可能地给他们带去欢乐。“比大地宽阔的是海洋,比海洋宽阔的是天空,比天空宽阔的是人的心灵。”宽容使狭隘的胸怀容纳百川,所以对待别人的过失,我都付笑谈中。 我,要做自己。齐白石老先生曾说过;“学我者生,似我者死。”走不出前人的框架,自然也就不会有自己的天地。当流行泡沫小说时,我感觉那时在浪费时间,当流行网络游戏时,我感觉那是在虚度青春。要做自己,看清真实的我,拿出十二分的信心,告诉自己:“我就是我,凭什么跟他一样?!”抛掉那些人为的浮华雕饰,亮出自己的王牌,追求自己的个性,做我自己,最好! 我,积极进取。小小的我是一粒沙,但不甘于落后,一生庸碌无为。我愿做生命的酋长,做一粒不朽的珍珠泪。路漫漫其修远兮,吾将上下而求索。我渴望朝向艺术之塔,文化之巅,事业之厦,庆功之缘,不负这繁花似锦的时代,留一行扎实稳健的足迹,把美和爱洒向人间…… 这就是我,只要一见到我,我总是笑,我会热情的和你打招呼。说了这么多,你还是很不怎么了解我吧。哈哈。那就来认识认识我呀,我也很喜欢交朋友的啦!2023-07-27 17:46:551

分辨率是扫描电镜最基本的性能判断指标,首先我们要弄清扫描电镜分辨率的一些细节问题。通常有关分辨率的问题,都会遵循瑞利判据。即一个光点按照衍射理论会是一个衍射斑,两个光点逐步靠近时,对应的衍射斑也从分离趋于重合。当两个衍射斑的半高宽重叠,则认为不可区分了。此时两个衍射斑之间的距离即为分辨率。 但一般单帧图像的仪器才完全符合此规律,比如TEM、光学显微镜等。扫描电镜的分辨率以瑞利判据为基础,但也却略有不同。扫描电镜是属于电子束移动型的,并不完全适用半高宽重合的概念。 扫描电镜的分辨率分为理论分辨率、验收分辨率,和一般测试过程中能达到的分辨率。1. 理论分辨率 扫描电镜的理论分辨率只能用电子束束斑所能达到的最小尺寸来进行描述,其达到样品上的束斑的直径理论上为:b9827a5e-d07e-4392-b391-100466e5b29837b6e031-5c12-4b62-a75d-6df24182153e 其中,d为理想状况下电子源汇聚点经过电磁透镜成像后的束斑大小、CS为电镜的球差系数、CC为色差系数、ΔV为灯丝单色性、V为加速电压、I0为束流、B为灯丝亮度、α为电子束汇聚的张角,λ为电子波长(远小于其它项)。 束斑直径D越小,电镜分辨率越高。我们详细分解一下上述公式: ① 高斯束斑dk项: 在不考虑任何非理想因素时,将电子镜筒完全看成是光学成像。电子源发出的电子在经过透镜、光阑、物镜后,束斑变小,这和光学仪器中的逐次成像基本一致,如图。96234401-7e1e-4227-be63-c6d8f20668fc电子束的逐次汇聚成像根据图中,我们可以得到到达样品上的束流I0为6a3a219e-0b3a-4d3e-a1ed-1d9cfa82ebf7 其中,αa越小,αj越大,束流越小。αa对应的光阑大小,αj对应聚光镜的励磁。再根据透镜逐次成像公式,我们得到束斑直径d为3092e3da-4576-48c2-acf8-3bee3b2828cb 或者根据亥姆赫兹-拉格朗日定则同样得到束斑直径d为37b6e031-5c12-4b62-a75d-6df24182153e 由公式我们便可得知不同的电子源d0相差很大,所以对d乃至最后实际电子束的直径有很大影响。其次,工作距离越近S越小,汇聚角α越大,聚光镜励磁越强αj越大,光阑孔径越小αa越小,均是有利于减小最后的束斑尺寸。 从这一点我们也能得出一个简单的结论,在实际操作过程中工作距离越小、光阑孔径越小、束流越小,分辨率越高。2023-07-27 17:47:552

天工开物在当时具有怎样的历史地位
宋应星是明末著名科学家。他的代表作《天工开物》图文并茂,详细记载了各种农作物和手工业原料的种类、产地、种植加工以及手工业生产技术,提供了大量确切数据,被誉为17世纪中国科技的百科全书。 《天工开物》先后被译成日、英、德、法、意、俄等多种文字,在世界科学技术从古代中世纪传统向近代科技转变的潮流中产生了一定影响。 明清之际,一些科学家重视实验,注重运用数理方法,开始显露出一些近代科学研究的特点。但从总体来看,明清的科学技术和西方近代科技相比,已远为逊色。特别是清朝实行文化专制,闭关锁国,使中国和西方科技水平的差距越拉越大。2023-07-27 17:42:578

《天工开物》的作者是谁?
宋应星。《天工开物》由明代著名科学家宋应星初刊于1637年(明崇祯十年丁丑),共三卷十八篇,作者在书中强调人类要和自然相协调、人力要与自然力相配合。是中国科技史料中保留最为丰富的一部,它更多地着眼于手工业,反映了中国明代末年出现资本主义萌芽时期的生产力状况。宋应星,明朝著名科学家,字长庚,江西奉新县瓦溪牌楼里(奉新县宋埠公社牌楼生产队)人。宋应星的著作和研究领域涉及自然科学及人文科学的不同学科,而其中最杰出的作品《天工开物》被誉为“中国17世纪的工艺百科全书”。作品鉴赏:宋应星在发展万物生成及演变的自然哲学时,把他的哲理与科学技术紧密结合起来,用《天工开物》中所述30 种技术过程的实例来支持并解释他的哲学思想。这不但是中国历史中其他哲学家作不到的,而且象李时珍那样的大科学家也未能作到这一点。2023-07-27 17:42:312

求大神看看,matlab中计算出来的结果是NaN+NANi,画图画不出来是怎么回事
用matlab中计算出来的结果是NaN+NANi,绘制图形时其图窗就是一张犹如白纸(即没有图形),这是因为NaN是不存在的数(如0/0)。所以题主在计算mirror_point(x_s,y_s,z_s,f)时,应调整计算初值,即不用0作为初值,可以用eps来作为初值。2023-07-27 17:42:241
