势能又称作位能,是指各物体相应位置之间的能量。 重力势能 就是一个物体转移位置时所需要的能量。 例如将木块由地面放到桌上,木块便会増加位能,而在木块跌下来的过程中,储存的位能亦会转化为动能。而当木块跌到地面的一瞬间,动能则会转化为声能及热能。 [编辑] 影响因素 影响位能强度的因素有: 物体的质量:较重的物体,所具有的位能亦较强。 地心吸力的强度:如在月球上,把物体抬高至与在地球的高度一样时,其所需能量不及地球,因为在月球受月心吸引力,比在地球受地心吸引力为小。 物体所在位置的高度:物 *** 置离地面较高的,所具有的位能亦较强。 [编辑] 计算重力势能 [编辑] 弹性势能 主条目:弹性势能 弹性位能是物体因为弹性形变而产生的位能。举例把一条橡皮筋放在向横拉直,橡皮筋因为具有弹性,最终会弹回原形。在位置上被拉长的橡皮筋两端,弹回原形时两端位置亦弹回。假定整条像皮筋没有移动过,而仅仅拉直过的话,橡皮筋弹回原形所产生的能量,便是弹性位能。 ===计算弹性位能===acute{κЯ}=(a+p) [编辑] 化学能 [编辑] 电势能 [编辑] 静电势能 [编辑] 电动势能 [编辑] 核势能 [编辑] 热势能 [编辑] 静态质能

Nominal GDP,Real GDP 和 Potential GDP的区别

Nominal GDP,即名义GDP也称货币GDP,是用生产物品和劳务的当年价格计算的全部最终产品的市场价值。名义GDP的变动可以有两种原因:一种是实际产量的变动,另一种是价格的变动。也就是说,名义GDP的变动既反映了实际产量变动的情况,又反映了价格变动的情况。Real GDP 即实际GDP是用从前某一年作为基期的价格计算出来的全部最终产品的市场价值,是名义GDP除以GDP平减指数求的。Potential GDP,即潜在GDP也称潜在产出或潜在国民收入、潜在的国内生产总值是指一国在一定时期内可供利用的经济资源在充分利用的条件下所能生产的最大产量,也就是该国在充分就业状态下所能生产的国内生产总值。这里的GDP就反映了在该时期内的最大产出能力。

元宵节手抄报英文版

  下面是提供的英文版元宵节手抄报,欢迎查看。    元宵节手抄报英文资料   The 15th day of the 1st lunar month is the Chinese Lantern Festival because the first lunar month is called yuan-month and in the ancient times people called night Xiao. The 15th day is the first night to see a full moon. So the day is also called Yuan Xiao Festival in China.   According to the Chinese tradition, at the very beginning of a new year, when there is a bright full moon hanging in the sky, there should be thousands of colorful lanterns hung out for people to appreciate. At this time, people will try to solve the puzzles on the lanterns and eat yuanxiao (glutinous rice ball) and get all their families united in the joyful atmosphere.   元宵节正月十五吃元宵的的习俗由来已久,元宵也叫“汤圆”、“圆子”。据说元宵象征合家团圆,吃元宵意味新的一年合家幸福、万事如意。   元宵节闹花灯的习俗起源于道教的“三元说”;正月十五日为上元节,七月十五日为中元节,十月十五日为下元节。主管上、中、下三元的分别为天、地、人三官,天官喜乐,故上元节要燃灯。元宵节的节期与节俗活动,是随历史的发展而延长、扩展的。就节期长短而言,汉代才一天,到唐代已为三天,宋代则长达五天,明代更是自初八点灯,一直到正月十七的夜里才落灯,整整十天。与春节相接,白昼为市,热闹非凡,夜间燃灯,蔚为壮观。特别是那精巧、多彩的灯火,更使其成为春节期间娱乐活动的高潮。至清代,又增加了舞龙、舞狮、跑旱船、踩高跷、扭秧歌等“百戏”内容,只是节期缩短为四到五天。    History   Until the Sui Dynasty in the sixth century, Emperor Yangdi invited envoys from other countries to China to see the colorful lighted lanterns and enjoy the gala(节日的,庆祝的)performances.   By the beginning of the Tang Dynasty in the seventh century, the lantern displays would last three days. The emperor also lifted the curfew(宵禁令), allowing the people to enjoy the festive lanterns day and night. It is not difficult to find Chinese poems which describe this happy scene.   In the Song Dynasty, the festival was celebrated for five days and the activities began to spread to many of the big cities in China. Colorful glass and even jade were used to make lanterns, with figures from folk tales painted on the lanterns.   However, the largest Lantern Festival celebration took place in the early part of the 15th century. The festivities continued for ten days. Emperor Chengzu had the downtown area set aside as a center for displaying the lanterns. Even today, there is a place in Beijing called Dengshikou. In Chinese, Deng means lantern and Shi is market. The area became a market where lanterns were sold during the day. In the evening, the local people would go there to see the beautiful lighted lanterns on display.   Today, the displaying of lanterns is still a big event on the 15th day of the first lunar month throughout China. People enjoy the brightly lit night. Chengdu in Southwest China"s Sichuan Province, for example, holds a lantern fair each year in the Cultural Park. During the Lantern Festival, the park is literally an ocean of lanterns! Many new designs attract countless visitors. The most eye-catching lantern is the Dragon Pole. This is a lantern in the shape of a golden dragon, spiraling up a 27-meter -high pole, spewing fireworks from its mouth. It is quite an impressive sight!   元宵节是中国的传统节日,早在2000多年前的西汉就有了,元宵赏灯始于东汉明帝时期,明帝提倡佛教,听说佛教有正月十五日僧人观佛舍利,点灯敬佛的做法,就命令这一天夜晚在皇宫和寺庙里点灯敬佛,令士族庶民都挂灯。以后这种佛教礼仪节日逐渐形成民间盛大的节日。该节经历了由宫廷到民间,由中原到全国的发展过程。   在汉文帝时,已下令将正月十五定为元宵节。汉武帝时,“太一神”的祭祀活动定在正月十五。(太一:主宰宇宙一切之神)。司马迁创建“太初历”时,就已将元宵节确定为重大节日。   另有一说是元宵燃灯的习俗起源于道教的“三元说”;正月十五日为上元节,七月十五日为中元节,十月十五日为下元节。主管上、中、下三元的分别为天、地、人三官,天官喜乐,故上元节要燃灯。   元宵节的节期与节俗活动,是随历史的发展而延长、扩展的。就节期长短而言,汉代才一天,到唐代已为三天,宋代则长达五天,明代更是自初八点灯,一直到正月十七的夜里才落灯,整整十天。与春节相接,白昼为市,热闹非凡,夜间燃灯,蔚为壮观。特别是那精巧、多彩的灯火,更使其成为春节期间娱乐活动的高潮。至清代,又增加了舞龙、舞狮、跑旱船、踩高跷、扭秧歌等“百戏”内容,只是节期缩短为四到五天。    Origin   There are many different beliefs about the origin of the Lantern Festival. But one thing for sure is that it had something to do with religious worship.   One legend tells us that it was a time to worship Taiyi, the God of Heaven in ancient times. The belief was that the God of Heaven controlled the destiny of the human world. He had sixteen dragons at his beck and call and he decided when to inflict drought, storms, famine or pestilence(瘟疫)upon human beings. Beginning with Qinshihuang, the first emperor to unite the country, all subsequent emperors ordered splendid ceremonies each year. The emperor would ask Taiyi to bring favorable weather and good health to him and his people. Emperor Wudi of the Han Dynasty directed special attention to this event. In 104 BC, he proclaimed it one of the most important celebrations and the ceremony would last throughout the night.   Another legend associates the Lantern Festival with Taoism. Tianguan is the Taoist god responsible for good fortune. His birthday falls on the 15th day of the first lunar month. It is said that Tianguan likes all types of entertainment. So followers prepare various kinds of activities during which they pray for good fortune.   The third story about the origin of the festival is like this. Buddhism first entered China during the reign of Emperor Mingdi of the Eastern Han Dynasty. That was in the first century. However, it did not exert any great influence among the Chinese people. one day, Emperor Mingdi had a dream about a gold man in his palace. At the very moment when he was about to ask the mysterious figure who he was, the gold man suddenly rose to the sky and disappeared in the west. The next day, Emperor Mingdi sent a scholar to India on a pilgrimage(朝圣)to locate Buddhist scriptures. After journeying thousands of miles, the scholar finally returned with the scriptures. Emperor Mingdi ordered that a temple be built to house a statue of Buddha and serve as a repository for the scriptures. Followers believe that the power of Buddha can dispel darkness. So Emperor Mingdi ordered his subjects to display lighted lanterns during what was to become the Lantern Festival.    关于元宵节的来历,民间还有几种有趣的传说:   关于灯的传说   传说在很久以前,凶禽猛兽很多,四处伤害人和牲畜,人们就组织起来去打它们,有一只神鸟困为迷路而降落人间,却意外的被不知情的猎人给射死了。天帝知道后十分震怒,立即传旨,下令让天兵于正月十五日到人间放火,把人间的人畜财产通通烧死。天帝的女儿心地善良,不忍心看百姓无辜受难,就冒着生命的危险,偷偷驾着祥云来到人间,把这个消息告诉了人们。众人听说了这个消息,有如头上响了一个焦雷。吓得不知如何是好,过了好久,才有个老人家想出个法子,他说:“在正月十四、十五、十六日这三天,每户人家都在家里张灯结彩、点响爆竹、燃放烟火。这样一来,天帝就会以为人们都被烧死了”。   大家听了都点头称是,便分头准备去了。到了正月十五这天晚上,天帝往下一看,发觉人间一片红光,响声震天,连续三个夜晚都是如此,以为是大火燃烧的火焰,以中大快。人们就这样保住了自己的生命及财产。为了纪念这次成功,从此每到正月十五,家家户户都悬挂灯笼,放烟火来纪念这个日子。    Yuanxiao   Besides entertainment and beautiful lanterns, another important part of the Lantern Festival,or Yuanxiao Festival is eating small dumpling balls made of glutinous rice flour. We call these balls Yuanxiao or Tangyuan. Obviously, they get the name from the festival itself. It is said that the custom of eating Yuanxiao originated during the Eastern Jin Dynasty in the fourth centuty, then became popular during the Tang and Song periods.   The fillings inside the dumplings or Yuansiao are either sweet or salty. Sweet fillings are made of sugar, Walnuts(胡桃), sesame, osmanthus flowers(桂花), rose petals, sweetened tangerine peel, bean paste, or jujube paste(枣泥). A single ingredient or any combination can be used as the filling . The salty variety is filled with minced meat, vegetables or a mixture.   The way to make Yuanxiao also varies between northern and southern China. The usual method followed in southern provinces is to shape the dough of rice flour into balls, make a hole, insert the filling, then close the hole and smooth out the dumpling by rolling it between your hands. In North China, sweet or nonmeat stuffing is the usual ingredient. The fillings are pressed into hardened cores, dipped lightly in water and rolled in a flat basket containing dry glutinous rice flour. A layer of the flour sticks to the filling, which is then again dipped in water and rolled a second time in the rice flour. And so it goes, like rolling a snowball, until the dumpling is the desired size.   The custom of eating Yuanxiao dumplings remains. This tradition encourages both old and new stores to promote their Yuanxiao products. They all try their best to improve the taste and quality of the dumplings to attract more customers.    汉文帝时为纪念“平吕”而设   另一个传说是元宵节是汉文帝时为纪念“平吕”而设。汉高祖刘邦死后,吕后之子刘盈登基为汉惠帝。惠帝生性懦弱,优柔寡断,大权渐渐落再吕后手中。汉惠帝病死后吕后独揽朝政把刘氏天下变成了吕氏天下,朝中老臣,刘氏宗室深感愤慨,但都惧怕吕后残暴而敢怒不敢言。   吕后病死后,诸吕惶惶不安害怕遭到伤害和排挤。于是,在上将军吕禄家中秘密集合,共谋作乱之事,以便彻底夺取刘氏江山。   此事传至刘氏宗室齐王刘囊耳中,刘囊为保刘氏江山,决定起兵讨伐诸吕随后与开国老臣周勃,陈平取得联系,设计解除了吕禄,“诸吕之乱”终于被彻底平定。   平乱之后,众臣拥立刘邦的第二个儿子刘恒登基,称汉文帝。文帝深感太平盛世来之不易,便把平息“诸吕之乱”的正月十五,定为与民同乐日,京城里家家张灯结彩,以示庆祝。从此,正月十五便成了一个普天同庆的民间节日——“闹元宵”。    元宵节英语词汇   元宵节:festival of lanterns,lantern festival dumplings   元宵: the rice glue ball   灯谜:riddles written on lanterns   灯具:lamps and lanterns   灯花 snuff   灯笼裤 bloomers galligaskins knickers pantalettes plus fours   灯笼 lantern scaldfish   灯塔 beacon lighthouse pharos   灯语 lamp signal   灯油 kerosene lamp oil   灯心蜻蜓 damselfly    我精心推荐

街舞Freeze要怎么撑啊?

街舞freeze步骤和方法第一步,一开始我们需要找到用肘部撑地地位置,其实说用肘部来完成freeze,大部分只是其中一个手用肘来撑地,另一个手还是用地手掌,那么双手地摆放姿势是一个手从手掌到肘部都平放在地板上,并保持手掌地方向向着身体前方,另一个手是用手掌撑地,撑地地位置是在另一个手地肘和掌中间那地方。第二步,双手摆放好之后,便可以开始试着使身体立上去,和倒立地原理一样,先用一个脚向后上方勾去,然后带动身体往上摆变成倒立地姿势。这里与倒立不同地是手臂地发力,用肘部支撑地时候发力地是整个小臂,从手掌尖到肘部都用来支撑,支撑面积更大,所以这个动作会相对倒立更轻松。第三步,便是保持身体在空中地停顿,和倒立一样,停顿地时间越长,动作越稳定就可以做出更多地变化,如最后一张图片,那是用肘部支撑地情况下,双脚做出一个Nike地动作。因为做肘部地freeze地时候,身体离地面地距离比倒立要更接近,所以肘部freeze地稳定性要比倒立更高,大家可以尝试用肘部做出更多形状地freeze。肘部freeze是介于空中地和地板之间地freeze,有着很好地过渡作用,掌握了肘部freeze之后对freeze地高低连接变化很有帮助。街舞是起源于美国,基于不同的街头文化或音乐风格而产生的多个不同种类的舞蹈的统称,最早的街舞舞种为Locking,起源于20世纪六十年代。(注:街舞的英文翻译有且仅有Street Dance这一种,Hiphop只是其中的一种) ,动作是由各种走、跑、跳组合而成,并通过头、颈、肩、上肢、躯干等关节的屈伸、转动、绕环、摆振、波浪形扭动等连贯组合而成的,各个动作都有其特定的健身效果,既注意了上肢与下肢、腹部与背部、头部与躯干动作的协调,又注意了组成各环节各部分独立运动。80年代传入中国,并逐渐作为健身活动传播开来。
