锌合金压铸的参数重点是比压和充填速度,两者是压铸过程中最重要的工艺参数。其他的工艺参数还有充型时间、模温等。
压铸(英文:die casting)是一种金属铸造工艺,其特点是利用模具腔对融化的金属施加高压。模具通常是用强度更高的合金加工而成的,这个过程有些类似注塑成型。大多数压铸铸件都是不含铁的,例如锌、铜、铝、镁、铅、锡以及铅锡合金以及它们的合金。根据压铸类型的不同,需要使用冷室压铸机或者热室压铸机。
锌合金是以锌为基础加入其他元素组成的合金。常加的合金元素有铝、铜、镁、镉、铅、钛等低温锌合金。锌合金熔点低,流动性好,易熔焊,钎焊和塑性加工,在大气中耐腐蚀,残废料便于回收和重熔;但蠕变强度低,易发生自然时效引起尺寸变化。熔融法制备,压铸或压力加工成材。按制造工艺可分为铸造锌合金和变形锌合金。

压铸工艺是将压铸机、压铸模和压铸合金三大要素有机合并并运用的过程;同时,这些因素互相影响而又互相制约。压铸的主要工艺参数为比压、充填速度、充型时间、模温。其中比压和充填速度是压铸过程中最重要的工艺参数。
铸造有哪些分类
问题一:铸造的铸造种类 为铸造技术使用最多的材料。 砂模铸造法(Sand Casting) 利用砂作为铸模材料,依不同成份的砂可再细分为湿砂模铸造法(Green Sand Mold)、表面干砂模铸造法(Dry Sand Mold)等等,但并非所有砂均可用以铸造。 好处是成本较低,因为铸模所使用的沙可重复使用;缺点是铸模制作耗时,铸模本身不能被重复使用,须破坏后才能取得成品。 金属模铸造法(Die Casting) 利用熔点较原料高的金属制作铸模。其中细分为重力铸造法、低压铸造法和高压铸造法。 受制于铸模的熔点,可被铸造的金属也有所限制。 失蜡法(Investment Casting、Lost-wax casting) 这方法可以为外膜铸造法和固体铸造法。 先以蜡复制所需要铸造的物件,然后浸入含陶瓷的池中并待干,使以蜡制的复制品覆上一层陶瓷外膜,一直重复步骤直到外膜足以支持铸造过程(约1/4寸到1/8寸),然后熔解模中的蜡,并抽离铸模。其后铸模需要多次加以高温,增强硬度后方可用以铸造。 此方法具有良好的准确性,更可用作高熔点金属(如钛)的铸造。但由于陶瓷价格颇高,而且制作需要多次加热和复杂,故成本颇为昂贵。 问题二:铸造分为几类? 按压力分:重力铸造 低力铸造 高压铸造 按成型方法:砂型铸造 消失模铸造 硅溶胶铸造 金属型铸造 V发铸造 问题三:铸造的主要工序有哪些? 铸造生产过程是一个复杂的综合性工序的组合,它包括许多生产工序和环节,从金属材料及非金属材料的准备,到合金熔炼,造型,制芯,合型浇注,清理,铸件消除缺陷热处理以至获得合格的铸件,铸造生产过程包括下列主要工序: 1. 型砂和芯砂的制备 型砂的制备过程直接影响到型砂的质量,型砂的制备一般分为原材料的准备及检验和型砂的制备及质量控制 2. 造型 用型砂及模样等工艺装备制造砂型的方法和过程称为造型。造型的方法种类很多,它取决于铸件的形状,大小,和技术要求 等。 3. 熔炼 通过加热使金属由固态转变为液体,并通过冶金反应去除金属液中的杂质,使其温度和成分达到规定要求的过程和操作成为熔炼。熔炼金属的设备种类较多,我们生产铸铁平台,机床铸件一般选用冲天炉。 4. 砂型烘干 对一些较大型或质量要求高的铸件一般采用干型浇注。例如大型铸铁平订,机床床身铸件,机床工作台,机床铸件等。 5. 浇注 将熔融金属从浇包注入铸型的操作称为浇注。 6. 清理 落砂后从铸件上清除表面粘砂,型砂和多余金属等的过程称为清理 7. 铸件热处理 将铸件加热到一定的温度范围,保温一段时间,再以规定的速度冷却到适当的温度,以获得预期的组织与性能的过程,叫铸件热处理。对铸件进行热处理的目的是为了消除铸件的铸造应力。比如铸铁平台,机床铸件,机床工作台都要经过热处理后才能进行加工。 问题四:常用的铸造方法有哪些 按照铸造工艺来分:砂型铸造和特种铸造两大类。砂型铸造又分为粘土砂,水玻璃砂,树脂砂等铸造;特种铸造又分为:消失模,离心,连续,熔模精密铸造(精铸)等; 问题五:铸件都有哪些种类和成分 按照逐渐的材料来分类:铸钢,铸铁(灰铁,球铁),高合金和有色金属铸件 按照铸造方法来分类:砂型铸造,熔模铸造(恭要是失蜡铸造),消失模铸造(lost foam),压铸 成分可以说是任意的,可以按照国标,ASTM,EN等标准,在熔炼时配比。 问题六:铸造属于什么行业 通常可以认为属于机械制造行业,但现在又靠到了材料行业!怎么说都行! 问题七:铸造原材料有那些品种? 铸造材料有很多种:有造型的(膨润土,煤粉,粘结剂,溃散剂,树脂,覆膜砂等),炉料类(除渣剂,增碳剂,孕育剂,脱氧剂,绩铁等)面包铁,废钢等。种类很多!不知你想哪方面的! 问题八:铸造材料有哪些? 常用铸造金属 1.灰铸铁 2.球墨铸铁 3.可锻铸铁 4.铸钢 常用铸造有色金属 1.黄铜 2.锡青铜 3.无锡青铜 4.铝合金铸造是人类掌握比较早的一种金属热加工工艺,已有约6000年的历史。中国约在公元前1700~前1000年之间已进入青铜铸件的全盛期,工艺上已达到相当高的水平。铸造是将液体金属浇铸到与零件形状相适应的铸造空腔中,待其冷却凝固后,以获得零件或毛坯的方法。[1] 被铸物质多为原为固态但加热至液态的金属(例:铜、铁、铝、锡、铅等),而铸模的材料可以是砂、金属甚至陶瓷。因应不同要求,使用的方法也会有所不同。2023-07-23 05:23:341

热室压铸热室压铸是在压铸生产过程中的主要技术。本节将主要讨论具体细节的热室压铸生产工艺与热室压铸分支之间的差异。热室的过程无论是压铸工艺相似的特点是高压力迫使熔融金属通过模具称为模具的使用。许多通过压铸生产铸件的高质量,(如大的表面细节),可以归因于压力,通过模具使金属流动中使用。热室压铸生产供应金属熔附于压铸机是制造操作的铸造设备的一个组成部分。镜头筒注射行程提供动力。它位于熔metal.the柱塞杆的供应从枪筒下柱塞,这与熔融物接触。在铸造循环柱塞在室的顶部开始(热室)摄入。端口允许本室充满液态金属。当周期开始的动力缸推动活塞向下。柱塞在港口切断金属液流动的热室。现在应该在室正确的熔融材料金额为“镜头”,将用于填充模具生产的铸件。在这一点上,柱塞旅行进一步向下迫使熔融金属模具。压力施加在金属液填充模具热室压铸制造通常从700psi到5000psi(5MPa~35MPa)。压力保持足够长的铸件凝固。在铸造生产的柱塞向上穿越回热室露出进气口又使腔室填充有熔融物的下一个周期的制备。对于更广泛的细节在模具的安装,压铸工艺,或性能的压铸模具制造考虑看到的基本过程铸造。热室压铸具有很高的生产率优势。工业生产过程的一个缺点是:在安装需要的关键部分的机械装置,(如柱塞),必须不断浸入熔融的材料。在足够高的温度,将这些材料连续淹水元器件绘制它们失效导致热损伤有关。由于这个原因,通常只有低熔点铅,锡点合金,锌用于制造与热室压铸过程铸件。2023-07-23 05:25:091
模压和压铸一样吗
压铸是一种利用高压强制将金属熔液压入形状复杂的金属模内的一种精密铸造法。在1964年,日本压铸协会对于压铸定义为“在高温将熔化合金压入精密铸模,在短时间内大量生产高精度而铸面优良的铸造方式”。美国称压铸为Die Casting,英国则称压铸为Pressure Die Casting,而最为国内一般业者所熟悉的是日本的说法,称为压铸。经由压铸法所制造出来的铸件,则称为压铸件,压力铸造简称压铸,是一种将熔融合金液倒入压室内,以高速充填钢制模具的型腔,并使合金液在压力下凝固而形成铸件的铸造方法。 压铸区别于其它铸造方法的主要特点是高压和高速。2023-07-23 05:25:192

压铸机合模阀和合模减压阀区别
压铸机的合模阀和合模减压阀对压力的控制不同:1、合模阀(Die-castingMachineClampingValve):合模阀主要用于控制压铸机的合模动作,即关闭合模时,通过液压系统提供足够的压力,将模具闭合,确保模具能够紧密地固定住铸件。合模阀通常由液压缸、液压控制阀等组成,根据需要控制液压油的进出来实现模具的开合动作。2、合模减压阀(Die-castingMachineMoldClampingReliefValve):合模减压阀是一种压力保护装置,用于在模具已完全闭合后,通过释放一定的压力,使系统中的压力降低到较低的水平。这样可以减轻对模具和机械结构的压力,减少对设备和模具的损坏风险。合模减压阀通常根据设定的压力值,进行自动或手动调节,确保在合模完成后压力得到适当的释放。2023-07-23 05:26:181

压铸和铸造有什么区别
浇铸是指金属液在地球重力作用下注入铸型的工艺,也称重力铸造。压力铸造是指金属液在其他外力(不含重力)作用下注入铸型的工艺。压铸的主要特点是金属液在高压、高速下充填型腔,并在高压下成形、凝固,压铸件的不足之处是:因为金属液在高压、高速下充填型腔的过程中,不可避免地把型腔中的空气夹裹在铸件内部,形成皮下气孔,所以铝合金压铸件不宜热处理,锌合金压铸件不宜表面喷塑(但可喷漆)。否则,铸件内部气孔在作上述处理加热时,将遇热膨胀而致使铸件变形或鼓泡。此外,压铸件的机械切削加工余量也应取得小一些,一般在 0.5mm左右,既可减轻铸件重量、减少切削加工量以降低成本,又可避免穿透表面致密层,露出皮下气孔,造成工件报废。2023-07-23 05:27:508
压铸过程中的问题,“拉模”是指什么?
拉模是产品有道拉伤的痕迹,主要是脱模不畅造成的(或模具有倒钩现象)。 压铸(英文:die casting)是一种金属铸造工艺,其特点是利用模具腔对融化的金属施加高压。模具通常是用强度更高的合金加工而成的,这个过程有些类似注塑成型。大多数压铸铸件都是不含铁的,例如锌、铜、铝、镁、铅、锡以及铅锡合金以及它们的合金。根据压铸类型的不同,需要使用冷室压铸机或者热室压铸机。 铸造设备和模具的造价高昂,因此压铸工艺一般只会用于批量制造大量产品。制造压铸的零部件相对来说比较容易,这一般只需要四个主要步骤,单项成本增量很低。压铸特别适合制造大量的中小型铸件,因此压铸是各种铸造工艺中使用最广泛的一种。同其他铸造技术相比,压铸的表面更为平整,拥有更高的尺寸一致性。 在传统压铸工艺的基础上诞生了几种改进型的工艺,包括减少铸造缺陷排除气孔的无孔压铸工艺。主要用于加工锌,可以减少废弃物增加成品率的直接注射工艺。还有由通用动力公司发明的精速密压铸技术以及半固态压铸等等新式压铸工艺。2023-07-23 05:28:261
粉末冶金与压铸有什么区别

铸造的行业特点:铸造是比较经济的毛坯成形方法,对于形状复杂的零件更能显示出它的经济性。如汽车发动机的缸体和缸盖,船舶螺旋桨以及精致的艺术品等。有些难以切削的零件,如燃汽轮机的镍基合金零件不用铸造方法无法成形。对于铸造工程师以及机械结构设计工程师而言,热处理是一项非常有意义,而具甚高价值用以改进材料品质的方法,借热处理可以改变或影响铸铁的组织及性质,同时可以获得更高的强度、硬度,而改善其磨耗抵抗能力等等。由于目的不同,热处理的种类非常多,基本主要可分成两大类,第一类是组织构造不会经由热处理而发生变化或者也不应该发生改变的,第二则是基本的组织结构发生变化者。第一热处理程序,主要用于消除内应力,而此内应力系在铸造过程中由于冷却状况及条件不同而引起。组织、强度及其他机械性质等,不因热处理而发生明显变化。扩展资料:铸造种类:为铸造技术使用最多的材料。砂模铸造法(SandCasting)利用砂作为铸模材料,依不同成份的砂可再细分为湿砂模铸造法(GreenSandMold)、表面干砂模铸造法(DrySandMold)等等,但并非所有砂均可用以铸造。好处是成本较低,因为铸模所使用的沙可重复使用;缺点是铸模制作耗时,铸模本身不能被重复使用,须破坏后才能取得成品。金属模铸造法(DieCasting)利用熔点较原料高的金属制作铸模。其中细分为重力铸造法、低压铸造法和高压铸造法。受制于铸模的熔点,可被铸造的金属也有所限制。失蜡法(InvestmentCasting、Lost-waxcasting)这方法可以为外膜铸造法和固体铸造法。先以蜡复制所需要铸造的物件,然后浸入含陶瓷的池中并待干,使以蜡制的复制品覆上一层陶瓷外膜,一直重复步骤直到外膜足以支持铸造过程(约1/4寸到1/8寸),然后熔解模中的蜡,并抽离铸模。其后铸模需要多次加以高温,增强硬度后方可用以铸造。此方法具有良好的准确性,更可用作高熔点金属(如钛)的铸造。但由于陶瓷价格颇高,而且制作需要多次加热和复杂,故成本颇为昂贵。参考资料:搜狗百科-铸造2023-07-23 05:28:451

英语童话故事,短一点,
愚公移山 (How Yu Gong Moved Away Two High Mountains) There were two high mountains between Jizhou in the south and Heyang in the north. One was called Taihang Mountain and the other Wangwu Mountain. Both of the mountains were very high. Just to the north of the mountains lived an old man called Yu Gong who was nearly 90 years old. With the two high mountains just in front of his house, his family and he had to walk a long way around the mountains whenever they had something to do on the other side of the mountains. One day, Yu Gong called all his family together to talk about how to move the two mountains to other places. His wife said, "An old man like you cannot even move a small hill, not to mention the two high mountains. Even if you can, where can you throw so much earth and stone?" "The Bohai Sea is big enough to contain all the earth and stone," Yu Gong said. So it was decided. His children started to dig the mountains, led by the old man Yu Gong. A man named Zhi Sou saw them working and tried to stop them, saying, "You are so silly! You"re so old and weak that you can"t even take away the grass and trees. How can you move the high mountains?" "You"re wrong," Yu Gong said with a sigh. "Look, my sons can continue my work after my death. When my sons die, my grandchildren will continue. So generations after generations, there"s no end. But the mountains can"t grow higher. Do you still say I can"t move them away?" Later the Heaven God, upon learning of Yu Gong"s story, was greatly moved. He then ordered another god to come down and take the two high mountains away. The story tells us that so long as one is determined and sticks to it long enough, anything can be done, no matter how difficult it is. 在冀州的南面,河阳的北面,有两座巍峨的大山,一座是太行,一座是王屋,方圆七百里,有万丈高. 山的北边住着年近90的愚公.由于家门被山挡住,每次外出全家人都要绕过大山,多走很多路. 一天,愚公把全家人召集到一起,商量着把两座大山移走.妻子说:“凭你的力量,连一座小山丘也移不走,何况这两座大山呢?再说,你就是能移走,那土石往哪里放呢?”愚公说:“渤海那么大,可以把土石扔到渤海里去.” 说干就干,愚公带领子孙们挖起山来.河曲的智叟看见了,笑着阻止道:“你真是太傻了!以你的残年余力,连山上的一根草都动不了,更何况大山?”愚公叹了口气说:“你错了.你想想,我死了以后还有我的儿子,我的儿子又有儿子,子子孙孙没有穷尽!可是山上的土石不会增加,还怕挖不走吗?” 愚公移山的事很快被玉皇大帝知道了.玉帝被愚公坚韧不拔的精神所感动,便派大力神把两座大山背走了. 这个故事告诉我们:只要有决心,有毅力,再难的事情也能办成. 伊索童话 - 狮子和老鼠 Aesop"s Fables The Lion and the Mouse Once when a Lion was asleep a little Mouse began running up and down upon him; this soon wakened the Lion, who placed his huge paw upon him, and opened his big jaws to swallow him. "Pardon, O King," cried the little Mouse: "forgive me this time, I shall never forget it: who knows but what I may be able to do you a turn some of these days?" The Lion was so tickled at the idea of the Mouse being able to help him, that he lifted up his paw and let him go. Some time after the Lion was caught in a trap, and the hunters who desired to carry him alive to the King, tied him to a tree while they went in search of a waggon to carry him on. Just then the little Mouse happened to pass by, and seeing the sad plight in which the Lion was, went up to him and soon gnawed away the ropes that bound the King of the Beasts. "Was I not right?" said the little Mouse. Little friends may prove great friends. 伊索童话 - 乌鸦喝水 Aesop"s Fables The Crow and the Pitcher A Crow, half-dead with thirst, came upon a Pitcher which had once been full of water; but when the Crow put its beak into the mouth of the Pitcher he found that only very little water was left in it, and that he could not reach far enough down to get at it. He tried, and he tried, but at last had to give up in despair. Then a thought came to him, and he took a pebble and dropped it into the Pitcher. Then he took another pebble and dropped it into the Pitcher. Then he took another pebble and dropped that into the Pitcher. Then he took another pebble and dropped that into the Pitcher. Then he took another pebble and dropped that into the Pitcher. Then he took another pebble and dropped that into the Pitcher. At last, at last, he saw the water mount up near him, and after casting in a few more pebbles he was able to quench his thirst and save his life. Little by little does the trick.2023-07-23 05:30:261
野天鹅 英文简介50-100字
The Wild Swans(野天鹅) Long ago and far away there lived a King. He was very proud of his eleven sons and one daughter. All of his children were good, kind and wise, even young Eliza who was still only a baby. The Queen had sadly died and after a while, feeling that his children needed a mother, the King married again. His new Queen was very jealous of the eleven princes and Eliza, and life for them soon changed. Eliza was sent to the country to be brought up on a farm. The Queen turned the King from his sons, by telling lies to him about them. Soon the King cared nothing for his sons. The Queen was delighted. "Go, you big ugly birds," she cried to them one day, casting a spell on them. But the worst she could do was to turn them into swans with golden crowns on their heads. Away they flew. They flew over the cottage where Eliza lived, but no-one saw them. Eliza lived happily at the farm, but she missed her brothers. When she was fifteen, she returned to the palace. The Queen was furious at how pretty Eliza had become, and would dearly have liked to turn her into a swan like her brothers. Instead she bathed Eliza and put three toads in to change her looks. The toads were instantly turned to poppies by Eliza"s innocence and goodness. The Queen then used walnut juice to darken Eliza"s skin, and matted her hair with fat. "This will make the King reject you," said the Queen, and the King did turn from Eliza. He did not know that this messy girl brought before him was his daughter. Eliza was very upset and decided to run away to look for her brothers. She went over the fields and through the forests. She came at last to a stream and saw her own reflection. "No wonder my father did not know me," she said, and she jumped in to wash herself. Moments later the real Eliza emerged, with clean golden hair and fair skin. For many days she walked, looking for her brothers. One day she met an old woman. She had a basket of fruit and shared some with Eliza. "Have you seen eleven princes riding through the forest?" asked Eliza. "I haven"t, my dear," said the old woman. " But yesterday I did see eleven swans riding down the stream. Each had a golden crown on his head." She showed Eliza the river. Eliza followed the river to the shore, and stood watching the waves. As the sun set, the swans turned into eleven princes with golden crowns on their heads. "My brothers!" cried Eliza, and she ran to greet them. They were delighted to see their younger sister, now grown into a lovely girl. They soon realised that it was because of the wicked Queen that they were rejected. "We are swans during the day," said the eldest. "But when the sun goes down, we regain our human form. We therefore have to be over land when the sun sets or we will be doomed." "We will take you with us when we leave tomorrow," said the youngest. "Tonight we must weave a net to carry you." All night the brothers and sister wove a net. In the morning as Eliza slept, eleven swans flew up into the air, carrying the net. The youngest shaded Eliza"s face from the sun with his wing. On the other side of the sea was a beautiful land. The brothers flew hard to reach it in daylight. "Here is your new home," they said as they landed. Eliza had a dream that night. A fairy came to her and said, "There is a way to save your brothers, but it means hardship and pain for you. There are stinging nettles around the cave. Gather them, although they will sting, and trample them with your feet. With the flax, weave and make up eleven mail shirts for your brothers. But you must never speak, from the moment you start until you finish, even if it takes years, or your brothers will die." Eliza awoke with a nettle stinging her hand. Her brothers had already left as it was broad daylight, so Eliza began her work. When they returned and saw her poor blistered hands, and she would not say a word, they realised that she was working for them. Two more days and the first shirt was finished. A day later, she was at her work, when the royal huntsmen came to the forest. She ran to her cave in fright, but the dogs followed her. The King was amongst the huntsmen and fell in love with Eliza when he saw her. "I"ll take you to the palace, where you may make your home," he told Eliza. Eliza was beautifully dressed, and the King chose to make her his Queen, but she would not smile or say a word. "My present to you," he said, taking her to a small chamber, "is a room like your cave, with all your familiar things around you." There Eliza saw the prepared nettles and the completed shirt and she was happy. Night after night the young Queen crept away from the King to continue her work. Soon seven shirts were completed, but she had no more flax. Eliza knew that the nearest nettles grew in the graveyard. At the dead of night, while all were asleep, she crept out to the graveyard. On a gravestone sat seven witches, counting the dead. Eliza walked straight past, with a shudder. The Archbishop was the only one to have seen Eliza leave, and he had followed her. He did not trust her, and thought she had bewitched the King. "The Queen is a witch," the Archbishop told the King. "I have proof." The King did not want to believe it, but he watched when Eliza went out at night. Night after night, she continued her weaving in the small room. Then one night, with one shirt to go, Eliza ran out of flax and nettles. She would have to visit the graveyard again. This time the King followed. He saw the witches on the gravestone and believed Eliza to be one of them. "The people must judge her," said the King sadly. And the people judged that she was a witch and should be burned at the stake. Eliza was thrown into prison. Her pillows and sheets were the nettle shirts. She could not have wished for better blankets, and she continued her work. Eleven princes arrived that night at the palace gate, demanding to see the king. "It"s too late to disturb the King," said the guards. Eleven swans flew off as dawn broke. Eliza was carried to the stake in a cart, still sewing and weaving the eleventh shirt. The others lay at her feet. "Look at the witch!" cried the mob. "She still sews! She"s casting spells Take it from her!" The people were about to tear the shirts from her when eleven swans appeared, golden crowns on their heads, flapping their wings and forcing the people back. The executioner went to tie Eliza to the sake, but Eliza quickly threw the shirts over her brothers, and they became princes again. Sadly the youngest still had a wing instead of an arm, as Eliza had not quite finished the shirt. "Now I may speak!" cried Eliza, turning to the King. The whole story was told to the King, who was very happy. He did not want to loose Eliza. As the eldest prince spoke, the wood at the stake blossomed and a huge rose bush sprang up. The King gave a rose to Eliza, and there was a happy wedding procession back to the palace, where the King and Eliza lived happily. 梗概版(200左右) In a faraway kingdom, there lives a King with his twelve children: eleven princes and one princess. One day, He marries a wicked Queen who is actually a witch. Out of spite, the queen turns her eleven stepsons into swans and forces them to fly away. The brothers carry Elisa to safety in a foreign land where she is out of harm"s way of her stepmother. The king of another faraway land happens to come across the mute Elisa and falls in love with her. Eventually he proposes to crown her as his Queen and wife, and she accepts. One night Elisa runs out of nettles and is forced to collect more in a nearby church graveyard, braving witches who feast on the graveyard corpses. She can speak no word in her defence and is sentenced to death by burning at the stake. The brothers discover Elisa"s plight and try to speak to the king, but fail. Even as the tumbril bears Elisa away to execution, she continues knitting, determined to keep it up to the last moment of her life. Then Elisa throws the shirts over the swans, and the brothers return to their human forms. The youngest brother retains one swan"s wing because Elisa did not have time to finish the last sleeve. Elisa can now speak and explain the reason for her mysterious work, but she faints from exhaustion, so her brothers explain. Elisa"s courage prevails, and she is forever reunited with her brothers.2023-07-23 05:30:361

But at that moment, I was unconsciously let tears flow down. Ten years ago, there are a lot of people ever cry for this scene.

大学如何做presentation?
1、学习知识。做好presentation,最重要的是要把内容做好。每一个小演讲都有固定的主题,要在主题范围内梳理好相应的知识框架。2、搜集资料。一个演讲,其内容是得分的关键部分。确定主题之后,可以开始查找资料,百度搜索是很好的方法。对于论文的搜索,可以通过中国知网等途径。3、图片收集。一个好的ppt不能缺少好的图片,要在网上选择合适的图片,同时也注意利用美化工具尽量将水印去掉,以防影响整体效果。4、制作PPT。一般来说,PPT的背景尽量选择同一个背景,字体大小适中,建议不要使用艺术字。PPT的动画设置不要过于花哨,排版好合理,文字图片相互融合。5、调整文字与图片。PPT大概制作完毕后,先在电脑上播放一遍,很多时候在播放的时候我们会发现某些图片过于大或过于小,因此要进行调整。文字内容的段落不宜过长,3至5行即可。6、演讲训练。所有的PPT制作完毕之后,要在上场前进行训练,每一页PPT自己所讲的内容要熟记于心,同时进行计时,总体presentation不宜过长或过短。内容应用一套完整的PPT文件一般包含:片头、动画、PPT封面、前言、目录、过渡页、图表页、图片页、文字页、封底、片尾动画等;所采用的素材有:文字、图片、图表、动画、声音、影片等。国际领先的PPT设计公司有:themegallery、poweredtemplates、presentationload等;中国的PPT应用水平逐步提高,应用领域越来越广。PPT正成为人们工作生活的重要组成部分,在工作汇报、企业宣传、产品推介、婚礼庆典、项目竞标、管理咨询、教育培训等领域占着举足轻重的地位。2023-07-23 05:29:431

如何做presentation
我不敢自称presentation高手,但我深谙外企presentation之道,这不是自吹自擂,而是十年外企工作经验的所得。所 谓presentation,不一定非是powerpoint presentation不可。外企对管理人员的衡量指标之一有一个selling skill,其实大多便是从presentation里面得来的印象。外企看重的presentation是所有外企员工展示自己能力最好的平台,不懂得 这个道理便做不好presentation.1. Title page或Front page(封面/首页)以powerpoint为例,一个好的presentation的封面页上要有以下几个要素:(1)演示题目(长度不超过一行的60%,如太长,应精简文字或设为两行。三行为大忌。)(2)副标题(不一定要有)(3)演示人姓名:常用的排版方式是全居中,也可以采用full block或half block,但要与选用的powerpoint template背景配合。(4)日期2. Introduction(简介)演示内容的简要介绍。3. Agenda(演示专题目录)这一点至关重要,目的是给听众一个清晰的脉络,给人条理性强的印象。但agenda的页面排版要注意:最好不要超过6行,每行注意长度不要超过页面一行的80%,保证页面整体的视觉效果清晰。4. 演示正文页面字数最忌太多。注意给页面给白,并且要按照信息的重要性排好次序,每行字数不要差别太大。正文页面不要使用全局中方式。有一种理论说,每行不要超过6个字,有一定的道理,但不一定。5. 目录页插入根据演示进程插入刚开始时的目录页,标明进程。以免观众忘记脉络。6. Visual aid适当使用视觉辅助手段很重要,但不要太多,以免喧宾夺主。所谓视觉辅助指的不是office自带的那些剪贴画,而是各种图形、图标等。office的各种图标也尽量不要使用。7. 动画效果与transitionOffice页面动画效果要慎用。除非某个页面有特别强调内容,也不要使用页面转换动画效果。这些都是不专业的表现。以上是powerpoint页面制作技术层面的要点,更重要的是演示时的理念。第一,要明确做演示的目的。如果是培训,要大量使用visual aid,否则枯燥的文字内容很难吸引听众的注意力。如果是工作汇报,要通过各种指标的分析(使用分析图表和图形),引出分析结果。第二,语速要变化。这一点不必多说。第三,不要背对观众。许多做powerpoint演示的人常犯的错误是看屏幕的时间太多,与观众的目光交流太少。给人以看录像的感觉,而容易使观众忽视演示人的表现。还要注意目光交流不能偏颇,防止部分观众感到被忽视。第四,适当发问。这是防止观众跑神的方法,但不能使用过多。第五,切忌照屏幕念稿。演示的内容绝不等于屏幕显示的那些字,否则观众用不了三页就没人看演示人了。演示的全2023-07-23 05:29:361
the truth that you leave
因为,leave 就有留下,落下的意思 比如,我把书包落在家里了 i left the bag in my home 这里的that you leave 是修饰truth 的定语从句,that 做leave 的宾语 因此是你留下的真相,这个翻译是正确的2023-07-23 05:29:334
An abundance of 能接可数名词吗
可以啊。例如:Aside from transforming plain old human skin into stem cells, the placenta andamniotic fluid seem to have an abundance of these cells.除了改变普通人类皮肤成干细胞,胎盘和羊水似乎有大量的这种细胞。People are looking forward to stores with an abundance of commodity supplies.商品供应充足的商店,众人向往。2023-07-23 05:29:322
