I am very gald to be here for your interview. my chinese name is which was given me by my parents. symbolizes peace, health and happiness.I also have an English name. my English name is which was given me by my a college English teacher who came from . represents being childish. In my teacher`s eye, I am a child forever.I am 24 years old. I come from city. My undergraduate period will be accomplished in university in July this year. Now I am trying my best for obtaining a key to this university.Generally speaking I am a hard working student especially do the thing that I am interested in. I will try my best to finish it no matter how difficult it is. when I was sophomore, I found web design was very intertesting.So I learnd it very hard. To weaver a homepage for myself ,I stayed with my personal computer half a month.And I am the first one in our class who own his homepage.Furthermore I am a person with perseverance because I firmly believe that persevercance can sometimes equal genius. just like an old proverb goes, there are only two creatures who can mount the pyramids ---the eagle and the snail.During the days preparing for the first examination, I insist on running everyday no matter what the weather was like. And just owing to this ,I could concentrate on my study and succeed in the end.Well, in my spare time, I like basketball, Chinese chess and pingpong. English is also my favorite. So I often go to English corner to practice my oral English and write compositions to improve my written ability, but I know my English is not good enough. so I will continue studying English hardOk, that`s all, thank you for your attention, my god bless you.2 The reason for my choiceI have been deeply impressed by the academic atmosphere when I came here last summer. In my opinion, (报考的大学) ***** university as one of the most famous university in our city,It provides people with enough room to get further enrichment .I think this is my first reason.The second one is I am long for doing some research in this universiy throughout my life . It`s a pleasure to be with my favorite scientifical research for my life-time. I suppose this is most important factor in my decision.Thirdly, I think further study is still urgent for me to realize myself vaule. Life is precious, one time for everyone including me. So it is necessary to seize any opportunity for self-development,espcially in the competitive modern world.3 plan in the postgraduateWell, thank you for question, I hope I can form systematic view of 大专业词汇 .

As the matter of fact , owing to rivers and fog, it maybe said without fear of exaggeration that城市名字 is a natural wonder. So it is pleasant to visit the city in any season except in summer. Because you know chongqing is unbearably hot during the summer.In a word , I love my hometown----城市名字 city more than people around me can imagin. I was born in this city and her culture have been having a profound influence on my life as well as my work.(在面试的时候,你的家乡就是你所报考的学校所在地,面试官也不知道你到底来自何方。因为没有方言交流的机会。面试官一般都是本地人,如果你和他们都是老乡,结果自然会朝着你希望的方向发展。)6 my university你的大学名字 is one of the oldest univeristy in provinceIt was founded in 1908 and covers an area of 2500 mu. The building area coves about 1000 mu. It develops into a comprehensive university with the efforts of generations especially after the reform and opening up. It takes lead among the same species universities with nice teaching and scientifical research ability. The labrary has a storage of 1.5 million books. And various research institutes are set up including 32 scientifical research center.

解放军文职招聘考试有机合成材料-解放军文职人员招聘-军队文职考试-红师教育

发布时间:2017-08-28 12:34:32有机化合物化合物可分为有机化合物和无机化合物,有机化合物都含有碳元素。碳的氧化物、碳酸、碳酸盐等具有无机化合物的特点,属于无机化合物。生活中常见的有机物甲烷(最简单的有机物、相对分子质量最小的有机物)、乙醇(俗名:酒精)、乙酸(俗名:醋酸)、葡萄糖、蔗糖、蛋白质、淀粉等有机物数目庞大的原因:原子的排列方式不同。在有机物中,碳原子可以和氮、氢、氧等原子直接结合,而且碳原子之间可以互相连接起来,形成碳链或碳环。根据相对分子质量大小,有机物可分为小分子(如甲烷、乙醇、乙酸、葡萄糖)和有机高分子化合物(如蛋白质、淀粉等)含碳、氢(含碳、氢、氧)的有机物在充分燃烧时,产物都是二氧化碳和水。而在不充分燃烧时,产物是一氧化碳和水。有机合成材料有机高分子材料有机高分子材料可分为天然有机高分子材料和合成有机高分子材料。棉花、羊毛、蚕丝、天然橡胶等属于天然有机高分子材料。棉花点燃后产生烧纸气味。塑料、合成纤维、合成橡胶是三大合成材料。高分子材料的结构和性质链状结构 热塑性 如:聚乙烯塑料、聚氯乙烯塑料网状结构 热固性 如:酚醛塑料(电木)、脲醛塑料(电玉)具有热塑性的塑料可以进行热修补。鉴别聚乙烯塑料和聚氯乙烯塑料:点燃后闻气味,有刺激性气味的为聚氯乙烯塑料。聚氯烯塑料袋有毒,不能装食品。鉴别羊毛线和合成纤维线:物理方法:用力拉,易断的为羊毛线,不易断的为合成纤维线。化学方法:点燃,产生烧焦羽毛气味,不易结球的为羊毛线;无气味,易结球的为合成纤维线。白色污染 及环境保护危害:①破坏土壤,污染地下水;②危害海洋生物的生存;③如果焚烧含氯塑料会产生有毒的氯化氢气体,从而对空气造成污染。解决途径:①减少使用不必要的塑料制品;②重复使用某些塑料制品,如塑料袋、塑料盒等;③使用一些新型的、可降解的塑料,如微生物降解塑料和光降解塑料等;④回收各种废弃塑料。塑料的分类是回收和再利用的一大障碍。我们要控制使用保鲜膜。常见物质的化学式单质

解放军文职招聘考试建筑材料的基本性质-解放军文职人员招聘-军队文职考试-红师教育

发布时间:2017-11-25 16:46:57建筑材料的基本性质1.力学性质(1)强度。材料在经受外力作用时抵抗破坏的能力,称为材料的强度。根据外力施加方向的不同,材料强度又可分为抗拉强度、抗压强度、抗弯强度和抗剪强度等。(2)材料的弹性、塑性、脆性与韧性。材料在承受外力作用的过程中,必然产生变形,如撤除外力的作用后,若材料几何形状恢复原状,则材料的这种性能称为弹性。若材料的几何形状只能部分恢复,而残留一部分不能恢复的变形,该残留部分的变形称为塑性变形。材料受力时,在无明显变形的情况下突然破坏,这种现象称为脆性破坏。具有这种破坏特性的材料,称为脆性材料,如玻璃、陶瓷等。在冲击、振动荷载的作用下,材料在破坏过程中吸收能量的性质称为韧性,吸收的能量越多韧性越好。2.建筑材料的基本物理参数(1)密度。材料在绝对密实状态下单位体积内所具有的质量称为密度(g/cm3)。(2)表观密度。材料在自然状态下(包含内部孔隙)单位体积所具有的质量,称为表观密度(g/m3或kg/m3)。(3)堆积密度。散粒状材料在自然堆积状态下单位体积的质量,称为堆积密度(g/cm3或kg/m3)。(4)孔隙率。材料中孔隙体积占材料总体积的百分率。材料中孔隙的大小,以及大小孔隙的级配是各不相同的,而且孔隙结构形态也各不相同,有的与外界相连通,称开口孔隙,有的与外界隔绝,称封闭孔隙。孔隙率是反映材料细观结构的重要参数,是影响材料强度的重要因素。除此之外,孔隙率与孔隙结构形态还对材料表观密度。吸水。抗渗。抗冻、干湿变形以及吸声、绝热等性能密切相关。因此,孔隙率虽然不是工程设计和施工中直接应用的参数,但却是了解和预估材料性能的重要依据。(5)空隙率。散粒状材料在自然堆积状态下,颗粒之间空隙体积占总体积的百分率,称为空隙率。(6)吸水率。材料由干燥状态变为饱水状态所增加的(所吸入水的)质量一:材料十质量之比的百分率,称为材料的吸水率。(7)含水率。材料内部所包含水分的质量占材料干质量的百分率,称为材料的含水率。3.建筑材料的耐久性建筑材料在使用过程中经受各种常规破坏因素的作用而能保持其使用性能的能力,称为建筑材料的耐久性。建筑材料在使用中逐渐变质和衰退直至失效,有其内部因素,也有外部因素。其内部因素有材料本身各种组分和结构的不稳定、各组分热膨胀的不一致,所造成的热应力、内部孔隙、各组分界面上化学生成物的膨胀等;其外部因素有使用中所处的环境和条件,诸如日光曝晒,大气、水、化学介质的侵蚀,温度湿度变化,冻融循环,机械摩擦,荷载的反复作用,虫菌的寄生等。这些内外因素,可归结为机械的。物理的。化学的、物理化学的及生物的作用。在实际工程中,这些因素往往同时综合作用于材料,使材料逐渐失效。

2017解放军文职公共基础知识:科技之复合新材料-解放军文职人员招聘-军队文职考试-红师教育

复合新材料使用的历史可以追溯到古代。从古至今沿用的稻草增强粘土和已使用上百年的钢筋混凝土均由两种材料复合而成。20世纪40年代,因航空工业的需要,发展了玻璃纤维增强塑料(俗称玻璃钢),从此出现了复合材料这一名称。50年代以后,陆续发展了碳纤维、石墨纤维和硼纤维等高强度和高模量纤维。70年代出现了芳纶纤维和碳化硅纤维。这些高强度、高模量纤维能与合成树脂、碳、石墨、陶瓷、橡胶等非金属基体或铝、镁、钛等金属基体复合,构成各具特色的复合材料。超高分子量聚乙烯纤维的比强度在各种纤维中位居第一,尤其是它的抗化学试剂侵蚀性能和抗老化性能优良。它还具有优良的高频声纳透过性和耐海水腐蚀性,许多国家已用它来制造舰艇的高频声纳导流罩,大大提高了舰艇的探雷、扫雷能力,在国内思嘉新材料开发的复合新材料代表了国内的较高水平。除在军事领域,在汽车制造、船舶制造、医疗器械、体育运动器材等领域超高分子量聚乙烯纤维也有广阔的应用前景。该纤维一经问世就引起了世界发达国家的极大兴趣和重视。
