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。

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。

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。

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。

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。

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

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.

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.

Alone a person"s time, before the death in prison at the last minute, he will pray: "I was afraid, give me the strength to face death!" Because he didn"t know whether he can in great pain, their beliefs and dignity defended to the end. When the British people as high treason people spit on him, for he is about to die, when he saw children under execution ground smiled at his death, I know that ignorance is a great deal of harm. When he suffered pain, at the end of the life, deeply with his last breath, when everyone thought that he asked for mercy, he used the power of life yell out a cry: "freedom"I originally thought that as long as I don"t talk, I won"t cry. 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. It is a deep shock.Wallace is dead after all, two-time faithless Bruce in front to the Scots, a deep breath and yelled: "you once with Wallace bleeding!" He draw out a sword, "now, you bleed with me, please!"Highland impressive, they sent a shock the whole world cry, "Wallace - Wallace -" so, they played like a poetic beauty, played at all do not lose the Scot"s face, earned his Wallace the same beliefs and the pursuit of freedom and the victory.The countless times in Wallace"s hand sword be inserted on a large green space, the sword handle on red ribbon has been flying to the end of the film, like the winner of the epitaph.Scottish bagpipe ring again, I have already can"t continue to calm. Brave heart as heroes of the rare.I believe that the movie is the art of living. But life is more real, naked.

英专生为啥要做presentation

英语专业的学生经常会做presentation,原因有以下几点:首先,做presentation多是以小组的方式进行,这可以锻炼团队协作能力,与他人的有效沟通能力,计划和执行能力。其次,做PPT的过程能够锻炼逻辑分析能力和信息总结提炼能力,而上台演示的过程能过锻炼语言表达能力,临场反应能力等到进入职场就会发现,presentation虽然很俗套,但是在这个过程中得到的益处匪浅。学生时代做presentation令人头疼,以后会发现这是一个很好地锻炼机会。

我的电脑用format不能格式化怎么办?

个人认为不能用FORMAT的原因有两种1.你没有在纯DOS下执行该命令2.你所在的DOS下没有FORMAT命令文件。进入到纯DOS系统的根目录下执行该命令即刻。 具体操作及注意事项如下这个命令到用BIOS引导到系统盘的纯DOS系统下的跟目录,然后输入format c:/s注意,因为XP可以用两种格式支持磁盘,NTF或FAT,而NTF在DOS下是读不出来的。所以在格式化持磁盘,NTF或FAT,而NTF在DOS下是读不出来的。所以在格式化前一定要用DIR命令读一下C盘的目录,确认有WINDOWS文件夹后再执行FORMAT命令,否则将格式化D盘。因为你格式化的是系统盘 所以一定要加上参数S,否则你安装后的系统将不能启动

板栗的胎座类型是什么?

胚珠着生的心皮壁部位,往往形成肉质突起,称为胎座(P1acenta)。胎座一般位于心皮的腹缝线上。心皮数目与联合状况的不同产生了多种胎座类型:边缘胎座(marginal placentation):单心皮或多心皮离生雌蕊,子房1室,胚珠沿心皮边缘着生,如豌豆、黄芪、甘草。边缘胎座是由单心皮的边缘愈合形成的。侧膜胎座(parietal placentation):多心皮合生,子房1室,胚珠着生于每一心皮的边缘,如黄瓜、紫花地丁。侧膜胎座的形成可能源于多个张开心皮的边缘彼此联合。中轴胎座(axile placentation):多心皮合生,子房多室,心皮的腹缝线向内卷入在中央融合形成中央轴,胚珠着生于每一心皮的内角上(即中轴上),如桔梗、百合、西红柿等。中轴胎座的形成可能源于多个边缘愈合心皮的在靠近中央的位置彼此联合。特立中央胎座(free central placentation):多心皮合生,子房1室,中轴由子房腔的底部升起,但不达于子房顶,胚珠着生于此轴上,如石竹科、报春花科植物。特立中央胎座是由于具中轴胎座的子房室间隔膜消失演化形成的。基生胎座(basal placentation):胚珠着生于子房底部,如向日葵。顶生胎座(apical placentation):胚珠着生于子房顶部而悬垂室中,如桑。基生胎座与顶生胎座可能源于特立中央胎座的大部分消失,也可能源于侧膜胎座的大部分简化。

钢琴曲the truth that you leave有什么背后的故事吗

感觉这个故事和豆花之恋好配。  那是个雪花漫天飞舞的早晨。在一个只有四张桌子的豆花小吃铺里,他是第一个顾客。   他跺着脚,搓着手,要了碗豆花和两根油条。一双细滑、白皙的手端来了一海碗热腾腾的豆花,上面滚着红红的辣椒油。顺着这双手,他看到了一个姑娘笑盈盈的大眼睛,眼里的微笑驱走了他满身的寒意。   或许太饿,他狼吞虎咽地吃起来,额头上不断冒汗,眼角也淌出了泪,嘴里不停地发出啧啧声。   姑娘咯咯笑着对他说,慢点吃,看你辣的,顺手递给他一条白毛巾。   他边擦边说,没想到北方的豆花是咸辣味的,我们南方的豆花是甜甜的。   姑娘睁大眼睛说,还有甜豆花?真想去尝尝。   他摇头说,冬天还是吃你这豆花够味,感冒都治好了。   顾客渐渐多了起来,姑娘在小小的铺子里忙碌着,粉红色的毛衣裹着丰满的身体,宛如严冬里的腊梅般俏丽绽放。   他每天都穿过马路来这里吃豆花,每次姑娘都给他递过来一条干净的白毛巾,那条白毛巾散发着淡淡的皂香。   公司派他到这个小城开展业务,跑完业务后他就来铺子里坐坐,慢慢和姑娘也熟识了。姑娘的母亲早逝,有个弟弟还在上学,为了减轻家里负担,高中毕业后她就开了这个铺子。因为父亲还在别处开着电器修理店维持一家生计,平时只有她一个人打理铺子。   姑娘不忙时就为他沏一杯热茶,然后拿出编织针坐在那里织毛衣,编织针在姑娘的手指间灵巧地穿梭,他镜片后的眼睛也在姑娘的手上身上游走。他给她讲跑业务的辛苦往事和南方的美景美食。姑娘听得入迷时就抬头望他,他笑着逗她说干脆以后嫁到南方好了,既享眼福又饱口福。姑娘羞红了脸,像红红的炉火,烧得他全身发热。   两团火燃烧了寂寞的冬夜。他俯在姑娘耳边说,你就是我百吃不厌的豆花。姑娘紧紧贴着他的胸膛说,那你就吃一辈子我的豆花吧。   整个冬天,他被豆花裹得有些透不过气,他盼着春天早点到来。   春天来了,他像候鸟一样飞走了,只不过他的迁徙方向是由北往南。   他穿着姑娘亲手织的毛衣,带着姑娘做的一保温瓶豆花,载着姑娘的体温和余香踏上了返程的列车。他发誓说会回来接姑娘,带她去南方圆梦。姑娘的大眼睛水汪汪、亮闪闪的,照得他不禁打了个寒战。   列车还没到站,他迫不及待地脱去了厚重的毛衣,这边的气温太高了,他换上了短袖衫。吃了一半的豆花也酸了,他连保温瓶一同扔进了垃圾筒。   回到南方的日子里,他又吃起了甜豆花,还恋上了如豆花一样甜腻腻的江南女子,包括她的嫁妆。   每天吃着甜豆花,他突然感到味觉麻木了,吃什么都索然无味。他是多么强烈地渴望再吃辣辣的咸豆花。多少个梦里,一碗碗咸豆花幻化成姑娘的一张张笑脸围着他飞转。   在一个飘雨的傍晚,他终于回到了阔别两年的北方小城。烟雨中他怎么也找不到当年的豆花小吃铺,细细辨认后才发现那里已经醒目地建起一家大酒楼。他失望地走着看着,附近一家同名的小吃铺子让他眼前一亮。   他犹豫地推开门,迎面走来的老太太问他要点什么,他点了豆花。   见店里人少,他就同老太太打听原来那家豆花小吃铺的姑娘的去向。老太太告诉他,那个豆花小吃铺的姑娘把铺子盘给她后,一个人带着孩子去南方找什么甜豆花了,还莫名其妙地恳求她一定要保留“豆花小吃”这个铺名呢。   老太太端来一碗白白的豆花就到厨房忙去了。他抖着手送进嘴里一勺豆花,什么滋味都没有,他又放了一大勺辣椒油,再吃一口,顿时泪流满面。■   (曾影荐自《新智慧文摘》)

怎样做好英文Presentation

怎样做好英文Presentation   在学习与工作中,经常需要我们用英文做一些主题展示,或表达思想,或介绍经验,或推广品牌... ... Presentation既像演讲,又不同于演讲,同在于都需要良好的语言组织能力和表达沟通技巧,异在于,相比于演讲的某些渲染效果,Presentation对于信息传达的精准性和简洁性要求更高,目的性更强,往往还会借助PPT这一媒介。因此,不论是在课堂还是工作中,能做好一个英文Presentation的能力都极为重要。   Language 语言篇   先说一点和语言不太相关的,毕竟声音对于语言的传达效果也有很大的影响。在做presentation时,最基本的要求是要让观众听清,特别是在背过身去时。除此之外,还要注意声音的变化,以吸引观众的注意。声音主要可以通过以下三个方面变化:   Speed语速   在讲话的过程中,适当的调整语速,或者做适当的停顿可以很好的吸引观众。   Intonation音调   高昂和低沉的.音调可以产生不同的强调效果   Volume音量   回想上课时,老师突然提高的音量是不是立刻给你提神?   接下来,咱们进入正题,谈一谈英文Presentation的语言   1. Simplicity and Clarity 简洁明了   Use short words and short sentences.   虽然在写作中老师常常鼓励我们用长难句,但是在注重效率的presentation中,应该多用清楚明白的短句和易懂的单词。   Do not use jargon, unless you are certain that your audience understands it.   除非你确定面向的观众是内行人,否则慎用行业术语。   In general, talk about concrete facts rather than abstract ideas.   总体上,多用使用具体的例子,少说抽象空洞的观点。   Use active verbs instead of passive verbs. Active verbs are much easier to understand.   这一点大家要注意:多用主动语态,这更有利于观众理解。   大家比较一下下面两个句子:   Toyota sold nine million vehicles last year.   Nine million vehicles were sold by Toyota last year.   第一句主动语态更好理解。当然,如果上述例子里发言者想要强调的是数量之大,第二个句子更合适,我们这里介绍的一般情况。   不过英语君提醒一下大家,在正规语体的写作中,比如邀请函,会议通知,被动语态会显得更加正式。   2. Signposting 指示语   Signpost本意是路标,这里的意思是发言者要使用特定的指示性词语来提示观众讲到了哪里,接下来讲什么。这在presentation的语言中是非常重要的一环,可以帮助观众理清框架。那么,有哪些指示语呢?   首先,在开头,要告诉观众演讲内容的框架,可以使用这样的句式:   I"ll start by ...(A)... Then Iu2019ll move on to ...(B)... After that Iu2019ll consider ...(C)... Lastly Iu2019ll quickly recap before concluding with ...(D)...   这样,观众就会理出如下框架:   Beginning:   1.Welcome   2.Introduction of Structure (now)   Body   1.A   2.B   3.C   Conclusion   1.Summing up   2.D   接下来,在演讲过程中,如果你想从上述的一点切换到另一点,可以用以下句式:   That"s all I have to say about ...(A)... Let"s turn now to ...(B)...   如果讲完了全部主干内容,准备总结以上内容,可以说:   Well, we"ve looked at the A, B and C, I"d like to sum up now.   总结完后,想要给出结论,可以说:   What does all this mean for us? Well, Iu2019d like to say/recommend/suggest that...   接下来,英语君为大家贴出在各种情况下常用的signpost,学起来:   Introducing the subject 介绍话题   I"d like to start by...   Let"s begin by...   First of all, I"ll...   Starting with...   I"ll begin by...   Finishing one subject 结束话题   Well, I"ve told you about...   That"s all I have to say about...   We"ve looked at...   So much for...   starting another 开启另一话题   Now we"ll move on to...   Let me turn now to...   Next...   Turning to...   I"d like now to discuss...   Let"s look now at...   Analyzing a point and giving recommendations 分析观点,给出建议   Where does that lead us?   Let"s consider this in more detail...   What does this mean for ABC?   Translated into real terms...   Giving an example 举例子   For example,...   A good example of this is...   As an illustration,...   To give you an example,...   To illustrate this point...   Dealing with questions 应对观众提问   We"ll be examining this point in more detail later on...   I"d like to deal with this question later, if I may...   I"ll come back to this question later in my talk...   Perhaps you"d like to raise this point at the end...   I won"t comment on this now...   Summarizing and concluding 概括与总结   In conclusion,...   Right, let"s sum up, shall we?   I"d like now to recap...   Let"s summarise briefly what we"ve looked at...   Finally, let me remind you of some of the issues we"ve covered...   If I can just sum up the main points...   Ordering 列观点   Firstly...secondly...thirdly...lastly...   First of all...then...next...after that...finally...   To start with...later...to finish up... ;
