Water-splashing Festival is the most characteristics festival of the Dai ethnic . There are a lot of folk tales about the origin of the festival. Here is one. Long long ago, there lived a tyrant in the Dai village. He stopped at no evil. He burned, killed and looted wherever he went. No one could get rid of him, because he was very powerful. He was afraid of neither water nor fire. One day, he came across a beautiful Dai girl. He already had six wives and he wanted that girl as his seventh. So he married her. His wives, all kind-hearted women, utterly detested the barbarous acts of the tyrant and decided to kill him in order to protect the innocent people. However, they were too weak to challenge him. They had to wait. One day, the tyrant came back with lots of trophies. That night, he got drunk. The seventh wife, his favorite, thought it was the right time to act. "Your Majesty," she said to the tyrant, "You're the strongest person in the world. So, you can live as long as you want." The tyrant was overjoyed. Being drunk, he was not as cautious as usual. "My dear," he said, "I have a fatal weakness. If my hair twists around my neck, I'll die." His wife memorized those words. When the tyrant fell asleep, the women began to act. They twisted his hair around his neck, and the tyrant died. But as soon as his head feel onto the ground, a big fire began. The women had no choice but to hold his head with their hands, doing it in turns, one for a year. Each time one wife finished her turn and passed on the head, the others would splash water on her to wash away bloodstains. Water splashing became a symbol of good luck, a way to wish good fortune to strangers, friends and family alike. The Water-Splashing Festival is in mid-April and lasts three to five days. People worship Buddha on this day, girls welcome home for the Buddha as splashing water on them, and then water on each other to express good wish. At first they use hands and bowl, then later use pots and barrels, while singing songs。 During Water Splashing Festival, people paddle dragon boats , let rise, flying lights and perform a variety of recreational activities such as traditional song and dance show 。泼水节是傣族最富民族特色的节日。有许多关于这个节日来源的传说,其中有一个是这样的:很早很早以前,傣族的村子里有一个凶恶的魔王,他烧杀抢掠、无恶不作,没有人能够制服他,因为他法力过人并且水火不侵。一天他看到了一个漂亮的傣族女孩,虽然他已经有六位妻子但他仍想把她霸占为妻。于是,他又把她抢来,作了他的第七个妻子。他的妻子们都是些心肠很好的女人,她们合计着如何杀死魔王来保护无辜的人们。然而,她们太过于柔弱,她们只有慢慢等待机会。一天,魔王带着许多战利品回来。那晚,魔王喝得酩酊大醉,他最喜欢的第七个妻子认为时机已经到了。她对魔王称颂道:“我尊贵的大王,您是世界上最强的人,所以,您可以得到永生”。魔王听了洋洋得意,他说:“我有一个致命的弱点,如果拔我的头发勒我的脖子,我就会死。”姑娘记住了他的话,在他熟睡时,她拔下魔王一根头发,勒住他的脖子。果然,魔王的头就掉了下来,变成一团火球,滚到哪里,邪火就蔓延到哪里。竹楼被烧毁,庄稼被烧焦。姑娘们没有办法,只能没人轮流抱着他的头,一年交换一次。每当交换时其他人要向她泼水,洗掉她身上的血迹。后来泼水成了一种好运的象征,向陌生人、朋友、家人泼水是对他们的一种祝福。泼水节在在公历4月中旬,历时3~5天。泼水节这一天人们要拜佛,姑娘们用漂着鲜花的清水为佛洗尘,然后彼此泼水嬉戏,相互祝愿。起初用手和碗泼水,后来便用盆和桶,边泼边歌。泼水节期间,还要举行赛龙船、放高升、放飞灯等传 统娱乐活动和各种歌舞晚会。

Water-splashing Festival is the most characteristics festival of the Dai ethnic . It is the New Year festival in Dai calendar in the period of June 6 to July 6。 It is said that there was a devil in Xishuangbanna many years ago, he is the public scourge. Devil's head rolled to here and there, where the fire broke out。 Only until girls held to it ,it will be put out. Girls shift every year and in very shift, the girl was given water to wash blood ,land on her feet, show gratitude and pay tribute. Devil's head was finally reduced to ashes, and people keep the habitude as a festival。People worship Buddha on this day, girls welcome home for the Buddha as splashing water on them, and then water on each other to express good wish. At first they use hands and bowl, then later use pots and barrels, while singing songs。 During Water Splashing Festival, people paddle dragon boats , let rise, flying lights and perform a variety of recreational activities such as traditional song and dance show 。泼水节是傣族最富民族特色的节日。泼水节是傣历的新年,节期在六月六日至七月六日之间。相传,西双版纳曾有一个混世魔王,为民害。魔王的头颅,滚到那里,那里就起火,只有姑娘抱住它,才能熄灭。姑娘们轮流值班,一年换一次。每逢换班时,人们都给姑娘泼水,用以冲洗血迹,逢凶化吉,表演感激,并致敬意。魔王的头终于化为灰烬,除旧布新的泼水节也由此成为习俗。 泼水节这一天人们要拜佛,姑娘们用漂着鲜花的清水为佛洗尘,然后彼此泼水嬉戏,相互祝愿。起初用手和碗泼水,后来便用盆和桶,边泼边歌。泼水节期间,还要举行赛龙船、放高升、放飞灯等传 统娱乐活动和各种歌舞晚会。

World Water Day (世界水日)[ 2006-03-22 12:20 ]1992年12月22日,联合国大会的47/193号决议设立了世界水日(每年3月22日)。这是提醒公众重视水资源问题的一个特殊的日子。在这个日子里,我们可以意识到:向人们提供纯净饮用水的切实努力和世界范围内对于水问题的认识提高,能够帮助我们在水资源问题上,做得更出色。 在2003年12月23日的58/217号决议中,大会宣布从2005年3月22日的世界水日开始,2005年至2015年为“生命之水”国际行动十年。 2006年世界水日的主题是"水与文化",将由联合国教科文领导。 About World Water Day World Day for Water, or unofficially World Water Day (WWD), occurs each year on March 22, as designated by United Nations General Assembly resolution. This day was first formally proposed in Agenda 21 of the 1992 United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro, Brazil. Observance was expected to begin in 1993 and has grown significantly ever since. The UN invited its member nations to devote this day to implementing UN recommendations and promoting concrete activities within their countries. Each year, one of various UN agencies involved in water issues takes the lead in promoting and coordinating international activities for WWD. World Day for Water 2006: Water and Culture WWD 2006 will be guided by the theme 'Water and Culture' under the leadership of United Nations Educational, Scientific and Cultural Organization (UNESCO). International Decade for Action 'Water for Life' 2005-20152005-2015年“生命之水”国际行动十年Water is crucial for sustainable development, including the preservation of our natural environment and the alleviation of poverty and hunger. Water is indispensable for human health and well-being.The United Nations General Assembly, in December 2003, proclaimed the years 2005 to 2015 as the International Decade for Action 'Water for Life'. The 'Water for Life' Decade was launched on 22nd March 2005 by the United Nations Secretary-General Kofi Annan with the following video message: Click to view the video messageDear friends,Water is essential for life. Yet many millions of people around the world face water shortages. Many millions of children die every year from water-borne diseases. And drought regularly afflicts some of the world's poorest countries. The world needs to respond much better. We need to increase water efficiency, especially in agriculture. We need to free women and girls from the daily chore of hauling water, often over great distances. We must involve them in decision-making on water management. We need to make sanitation a priority. This is where progress is lagging most. And we must show that water resources need not be a source of conflict. Instead, they can be a catalyst for cooperation. Significant gains have been made. But a major effort is still required. That is why this year marks the beginning of the "Water for Life" Decade. Our goal is to meet the internationally agreed targets for water and sanitation by 2015, and to build the foundation for further progress in the years beyond. This is an urgent matter of human development, and human dignity. Together, we can provide safe, clean water to all the world's people. The world's water resources are our lifeline for survival, and for sustainable development in the 21st century. Together, we must manage them better.

The impact of climate Water has a regulatory role on the climate. Water vapor in the atmosphere can block the radiation the Earth 60%, the protection of the Earth is not cooling. Marine and terrestrial water body can absorb in the summer and accumulation of heat, so temperature is not too high; in the winter can slowly release heat, so temperature is not too low. Marine and surface evaporation of water into the sky formed a cloud, cloud water through precipitation Down to become rain, winter will be turned into snow. Drop-in on the surface of the water to seep into the ground floor of the formation of groundwater; groundwater out from the stratum to form a spring, through streams, and rivers into the sea. Form a cycle. Rain and snow precipitation, such as activities on the important impact of climate formation. In temperate monsoon climate, the monsoon brings a wealth of water vapor to form a distinct wet and dry autumn. In addition, in nature, because of different climatic conditions, water will be to hail, fog, dew, frost, such as the form and influence the climate and human activities. The impact of geographical 71% of the Earth's surface has been covered with water from the air, the earth is a blue planet. Water erosion of rock soil, river erosion and deposition, sediment transport, and create a plain, changes in surface morphology. The Earth surface water constitute the hydrosphere, including the oceans, rivers, lakes, swamps, glaciers, snow cover, groundwater and atmospheric water. Injected into the ocean because of the water with some salt, together with the annual accumulation and evaporation, sea and ocean water is salt water, should not be used directly for drinking. Some lakes also contain saline water. The world's largest body of water in the Pacific. North American Great Lakes are the largest freshwater systems. Eurasia on the Caspian Sea is the largest saltwater lake. The size of the Earth, Sheung Shui, there is around 1.36 billion cubic kilometers. Which Ocean account for the 1.32 billion cubic kilometers (or 97.2%). Glaciers and ice sheets accounted for 25 million cubic kilometers (or 1.8%). Groundwater accounts for 13 million cubic kilometers (or 0.9%). Lakes, inland seas, and the river of fresh water accounts for 250 000 cubic kilometers (or 0.02%). Water vapor in the atmosphere at any known time has a market share of 13 000 cubic kilometers (or 0.001%). The impact of life Life on Earth first emerged in the water. Water are all essential components of organisms. The body of water 70%; while 98 percent are jellyfish in the water. Living in the water a lot of aquatic vegetation and other aquatic organisms. Water is conducive to the conduct of chemical reactions in vivo, in living organisms also play a role in the transport of substances. Water temperature for maintaining the stability of organisms plays an important role. 意思: 对气候的影响 水对气候具有调节作用。大气中的水汽能阻挡地球辐射量的60%,保护地球不致冷却。海洋和陆地水体在夏季能吸收和积累热量,使气温不致过高;在冬季则能缓慢地释放热量,使气温不致过低。 海洋和地表中的水蒸发到天空中形成了云,云中的水通过降水落下来变成雨,冬天则变成雪。落于地表上的水渗入地下形成地下水;地下水又从地层里冒出来,形成泉水,经过小溪、江河汇入大海。形成一个水循环。 雨雪等降水活动对气候形成重要的影响。在温带季风性气候中,季风带来了丰富的水气,形成明显的干湿两季。 此外,在自然界中,由于不同的气候条件,水还会以冰雹、雾、露水、霜等形态出现并影响气候和人类的活动。 对地理的影响 地球表面有71%被水覆盖,从空中来看,地球是个蓝色的星球。水侵蚀岩石土壤,冲淤河道,搬运泥沙,营造平原,改变地表形态。 地球表层水体构成了水圈,包括海洋、河流、湖泊、沼泽、冰川、积雪、地下水和大气中的水。由于注入海洋的水带有一定的盐分,加上常年的积累和蒸发作用,海和大洋里的水都是咸水,不能被直接饮用。某些湖泊的水也是含盐水。世界上最大的水体是太平洋。北美的五大湖是最大的淡水水系。欧亚大陆上的里海是最大的咸水湖。 地球上水的体积大约有 1 360 000 000 立方公里. 当中 海洋占了的1 320 000 000立方公里(或97.2%)。 冰川和冰盖占了25 000 000立方公里(或1.8%)。 地下水占了13 000 000立方公里(或者0.9%)。 湖泊,内陆海,和河里的淡水占了250 000 立方公里(或0.02%)。 大气中的水蒸气在任何已知的时候都占了13 000立方公里(或0.001%)。 对生命的影响 地球上的生命最初是在水中出现的。水是所有生物体的重要组成部分。人体中水占70%;而水母中98%都是水。水中生活着大量的水生植被等水生生物。 水有利于体内化学反应的进行,在生物体内还起到运输物质的作用。 水对于维持生物体温度的稳定起很大作用。 回答者: xubingsong2 - 试用期 一级 3-12 21:17The importance of water It goes without saying water means the headspring to the all lives living on the earth.For this reason water is considered to be the most important matter.With the exception of this water qualifies other important worthinesses.Here below is a list of some of them.

水(H2O)是由氢、氧两种元素组成的无机物,在常温常压下为无色无味的透明液体。水是最常见的物质之一,是包括人类在内所有生命生存的重要资源,也是生物体最重要的组成部分。水在生命演化中起到了重要的作用。人类很早就开始对水产生了认识,东西方古代朴素的物质观中都把水视为一种基本的组成元素,水是中国古代五行之一;西方古代的四元素说中也有水。 水的性质 水在常温常压下为无色无味的透明液体。在自然界,纯水是罕见的,水通常多是酸、碱、盐等物质的溶液,习惯上仍然把这种水溶液称为水。纯水可以用铂或石英器皿经过几次蒸馏取得,当然,这也是相对意义上纯水,不可能绝对没有杂质。水是一种可以在液态、气态和固态之间转化的物质。固态的水称为冰;气态叫水蒸汽。水汽温度高于374.2℃时,气态水便不能通过加压转化为液态水。 在20℃时,水的热导率为0.006 J/scmK,冰的热导率为0.023 J/scmK,在雪的密度为0.1103 kg/m3时,雪的热导率为0.00029 J/scmK。水的密度在3.98℃时最大,为1103kg/m3,温度高于3.98℃时,水的密度随温度升高而减小 ,在0~3.98℃时,水不服从热胀冷缩的规律,密度随温度的升高而增加。水在0℃时,密度为0.99987103 kg/m3,冰在0℃时,密度为0.9167103 kg/m3。因此冰可以浮在水面上。 水的热稳定性很强,水蒸气加热到2000K以上,也只有极少量离解为氢和氧,但水在通电的条件下会离解为氢和氧水。具有很大的内聚力和表面张力,除汞以外,水的表面张力最大,并能产生较明显的毛细现象和吸附现象。纯水有极微弱的导电能力,但普通的水含有少量电解质而有导电能力。 水本身也是良好的溶剂,大部分无机化合物可溶于水。 在-213.16℃,水分子会表现出现厌水性。[1] 水的来源 地球是太阳系九大行星之中唯一被液态水所覆盖的星球。地球上水的起源在学术上存在很大的分歧,目前有几十种不同的水形成学说。有观点认为在地球形成初期,原始大气中的氢、氧化合成水,水蒸气逐步凝结下来并形成海洋;也有观点认为,形成地球的星云物质中原先就存在水的成分。另外的观点认为,原始地壳中硅酸盐等物质受火山影响而发生反映、析出水分。也有观点认为,被地球吸引的彗星和陨石是地球上水的主要来源,甚至现在地球上的水还在不停增加。 水和水体的作用 对气候的影响 水对气候具有调节作用。大气中的水汽能阻挡地球辐射量的60%,保护地球不致冷却。海洋和陆地水体在夏季能吸收和积累热量,使气温不致过高;在冬季则能缓慢地释放热量,使气温不致过低。 海洋和地表中的水蒸发到天空中形成了云,云中的水通过降水落下来变成雨,冬天则变成雪。落于地表上的水渗入地下形成地下水;地下水又从地层里冒出来,形成泉水,经过小溪、江河汇入大海。形成一个水循环。 雨雪等降水活动对气候形成重要的影响。在温带季风性气候中,季风带来了丰富的水气,形成明显的干湿两季。 此外,在自然界中,由于不同的气候条件,水还会以冰雹、雾、露水、霜等形态出现并影响气候和人类的活动。 对地理的影响 地球表面有71%被水覆盖,从空中来看,地球是个蓝色的星球。水侵蚀岩石土壤,冲淤河道,搬运泥沙,营造平原,改变地表形态。 地球表层水体构成了水圈,包括海洋、河流、湖泊、沼泽、冰川、积雪、地下水和大气中的水。由于注入海洋的水带有一定的盐分,加上常年的积累和蒸发作用,海和大洋里的水都是咸水,不能被直接饮用。某些湖泊的水也是含盐水。世界上最大的水体是太平洋。北美的五大湖是最大的淡水水系。欧亚大陆上的里海是最大的咸水湖。 地球上水的体积大约有 1 360 000 000 立方公里. 当中 海洋占了的1 320 000 000立方公里(或97.2%)。 冰川和冰盖占了25 000 000立方公里(或1.8%)。 地下水占了13 000 000立方公里(或者0.9%)。 湖泊,内陆海,和河里的淡水占了250 000 立方公里(或0.02%)。 大气中的水蒸气在任何已知的时候都占了13 000立方公里(或0.001%)。 对生命的影响 地球上的生命最初是在水中出现的。水是所有生物体的重要组成部分。人体中水占70%;而水母中98%都是水。水中生活着大量的水生植被等水生生物。 水有利于体内化学反应的进行,在生物体内还起到运输物质的作用。 水对于维持生物体温度的稳定起很大作用。 水的种类 不同的学科对水有着一些不同的称呼: 根据水质的不同,可以分为: 软水:硬度低于8度的水为软水。 硬水:硬度高于8度的水为硬水。硬水会影响洗涤剂的效果,硬水加热会有较多的水垢。 饮用水根据氯化钠的含量,可以分为: 淡水。 咸水 此外还有: 生物水:在各种生命体系中存在的不同状态的水。 天然水: 土壤水:贮存于土壤内的水 地下水:贮存于地下的水 超纯水:纯度极高的水,多用于集成电路工业 结晶水:又称水合水。在结晶物质中,以化学键力与离子或分子相结合的、数量一定的水分子。 重水的化学分子式为D2O,每个重水分子由两个氘原子和一个氧原子构成。重水在天然水中占不到万分之二,通过电解水得到的重水比黄金还昂贵。重水可以用来做原子反应堆的减速剂和载热剂。 超重水的化学分子式为T2O,每个重水分子由两个氚原子和一个氧原子构成。超重水在天然水中极其稀少,其比例不到十亿分之一。超重水的制取成本比重水还要高上万倍。 氘化水的化学分子式为HDO,每个分子中含一个氢原子、一个氘原子和一个氧原子。用途不大。 与水相关的化学反应 水的电离与溶液pH值 水是一种极弱的电解质,它能微弱地电离: H2O+H2O↔H3O++OH- 通常H3O+简写为H+ 水的离子积 Kw=[H+][OH-] 25度时,Kw=110-14 pH=-log10([H+]) pH<7,溶液为酸性,pH=7,溶液为中性,pH>7,溶液为碱性。 能溶于水的酸性氧化物或碱性氧化物都能与水反应,生成相应的含氧酸或碱。酸和碱发生中和反应生成盐和水。水在电流的作用下能够分解成氢气和氧气。碱金属和水接触会发生燃烧。 在催化剂的作用下,无机物和有机物能够与水进行水解反应: 有机物的水解:有机物分子中的某种原子或原子团被水分子的氢原子或羟基(-OH)代换,例如乙酸甲酯的水解: 无机物的水解:通常是盐的水解,例如弱酸盐乙酸钠与水中的H+结合成弱酸,使溶液呈碱性: 此外,水本身也可以作为催化剂。 淡水短缺问题与对策 地球上水总储量约为1.36x1018m3,但除去海洋等咸水资源外,只有2.5%为淡水。淡水又主要以冰川和深层地下水的形势存在,河流和湖泊中的淡水仅占世界总淡水的0.3%。 世界气象组织于1996年初指出:缺水是全世界城市面临的首要问题,估计到2050年,全球有46%的城市人口缺水。对于水资源稀少的地区来说,水已经超出生活资源的范围,而成为战略资源,由于水资源的稀有性,水战争爆发的可能性越来越高。 为让全世界都关心淡水资源短缺的问题,第47届联合国大会确定每年3月22日为世界水日。 水文化 请参看水文化 水滴扬起水在科学、哲学、宗教、文学、美术、体育、神话等中都有所体现。 水的利用 水是人类生活的重要资源,特别是农业需要大量水进行灌溉,人类文明的起源大多都在大河流域。早期城市一般都在水边建立,以解决灌溉、饮用和排污问题。在人类日常生活中,水在饮用、清洁、洗涤等方面的作用不可或缺。 随着科学技术的发展,人们兴修水利,与水涝害和洪水等自然灾害作斗争。因此形成了一些专门与水有关的研究领域,如水力学,水文科学,水处理等,甚而产生了以水为生的产业水产业。 工业生产和化工生产大量使用这种廉价的原料。但未经处理的废水的任意排放就会造成水污染。为了解决这一问题,污水的处理就变得十分必要。 (见水污染和污水处理。) 古代世界观中的水 在文明的早期,人们开始探讨世界各种事物的组成或者分类,水在其中扮演了重要角色。古代西方提出的四元素说中就有水;佛教中的四大也有水;中国古代的五行学说中水代表了所有的液体,以及具有流动、润湿、阴柔性质的事物。 水崇拜 在人类的童年时期,对于水兼有养育与毁灭能力、不可捉摸的性情,产生了又爱又怕的感情,产生了水崇拜。通过赋予水以神的灵性,祈祷水给人类带来安宁、丰收和幸福。 中国传统上的龙王就是对水的神格化。凡有水域水源处皆有龙王,龙王庙、堂遍及全国各地。祭龙王祈雨是中国传统的信仰习俗。
