坎儿井英文作文

Karez is a water conservancy system found in the dry region of Xinjiang, in which underground channels join wells to-gether. The system collects a large amount of rainwater and melted snow water that seep underground, and drains the water to the ground by the natural mountain slope for the irrigation of fields and the daily use. Karez reduces the evap-oration on the ground and does little harm to the surface, thus protecting natural resources and the ecological envi-ronment effectively. The system embodies the Chinese wisdom that people and nature co-exist in harmony, and is well recognized as a major contribution to the human civili-zation. 坎儿井(Karez)是新疆干旱地区的一种水利系统，由地下渠道将水井连接而成。该系统将春夏季节渗入(seep into)地下的大量雨水及积雪融水收集起来，通过山体的自然坡度引到地面，用于灌溉农田和满足人们的日常用水需求。坎儿井减少了水在地面的蒸发(evaporation)，对地表破坏很小，因而有效地保护了自然资源与生态环境。坎儿井体现了我国人民与自然和谐共存的智慧，是对人类文明的一大贡献。

画龙点睛（Putting the Finishing Touch to the Picture of a Dragon）In the Southern and Northern Dynasties Period (420-589), there was a painter called Zhang Sengyou. Once he visited a temple and painted on the wall four dragons, but gave none of them eyes. The onlookers felt that this was odd, and asked why he hadn't painted the eyes. He answered, 'Eyes are crucial for dragons. With the eyes painted on, the dragons would fly away.' Nobody believed this, so Zhang Sengyou took up his brush and added eyes to two of the dragons. No sooner had he finished than the two dragons flew into the sky amid a thunderstorm. The two without eyes stayed painted on the wall.

这是一篇新出的杂志文章Amazon's recommendation secretWhen Amazon recommends a product on its site, it is clearly not a coincidence. At root, the retail giant's recommendation system is based on a number of simple elements: what a user has bought in the past, which items they have in their virtual shopping cart, items they've rated and liked, and what other customers have viewed and purchased. Amazon (AMZN) calls this homegrown math "item-to-item collaborative filtering, " and it's used this algorithm to heavily customize the browsing experience for returning customers. A gadget enthusiast may find Amazon web pages heavy on device suggestions, while a new mother could see those same pages offering up baby products. Judging by Amazon's success, the recommendation system works. The company reported a 29% sales increase to $12.83 billion during its second fiscal quarter, up from $9.9 billion during the same time last year. A lot of that growth arguably has to do with the way Amazon has integrated recommendations into nearly every part of the purchasing process from product discovery to checkout. Go to Amazon.com and you'll find multiple panes of product suggestions; navigate to a particular product page and you'll see areas plugging items "Frequently Bought Together" or other items customers also bought. The company remains tight-lipped about how effective recommendations are. ("Our mission is to delight our customers by allowing them to serendipitously discover great products, " an Amazon spokesperson told Fortune. "We believe this happens every single day and that's our biggest metric of success.") Amazon also doles out recommendations to users via email. Whereas the web site recommendation process is more automated, there remains to this day a large manual component. According to one employee, the company provides some staffers with numerous software tools to target customers based on purchasing and browsing behavior. But the actual targeting is done by the employees and not by machine. If an employee is tasked with promoting a movie to purchase like say, Captain America, they may think up similar film titles and make sure customers who have viewed other comic book action films receive an email encouraging them to check out Captain America in the future. Amazon employees study key engagement metrics like open rate, click rate, opt-out -- all pretty standard for email marketing channels at any company -- but lesser known is the fact that the company employs a survival-of-the-fittest-type revenue and mail metric to prioritize the Amazon email ecosystem. "It's pretty cool. Basically, if a customer qualifies for both a Books mail and a Video Games mail, the email with a higher average revenue-per-mail-sent will win out, " this employee told Fortune. "Now imagine that on a scale across every single product line -- customers qualifying for dozens of emails, but only the most effective one reaches their inbox." The tactic prevents email inboxes from being flooded, at least by Amazon. At the same time it maximizes the purchase opportunity. In fact, the conversion rate and efficiency of such emails are "very high, " significantly more effective than on-site recommendations. According to Sucharita Mulpuru, a Forrester analyst, Amazon's conversion to sales of on-site recommendations could be as high as 60% in some cases based off the performance of other e-commerce sites. Still, although Amazon recommendations are cited by many company observers as a killer feature, analysts believe there's a lot of room for growth."There's a collective belief within the e-commerce industry that Amazon's recommendation engine is a suboptimal solution, " says Mulpuru. Trisha Dill, a Well's Fargo analyst, says it's hard to fault Amazon for their recommendations, but she also says the company has a lot of work to do in offering users items more relevant to them. As an example, she points to a targeted email she received pushing a chainsaw carrying case. (She doesn't own a chainsaw.) Besides refining the accuracy of recommendations themselves, Amazon could explore more ways to reach customers. Already, the company has begun selling items previously sold in bulk that were too cost-prohibitive to ship individually like say, a deck of cards or a jar of cinnamon. Customers may buy them, but only if they have an order totaling $25 or over. But the company could actively recommend these add-on products during check-out when an order crosses that pricing threshold, much like traditional supermarkets have impulse-purchase items like gum and candy bars at the register. At that point, the Amazon customer, just as they would in the supermarket, might think, "It's just a few more bucks. Why not? 推销高手亚马逊的秘密 我们都知道Facebook、谷歌以及苹果等公司十分了解用户。事实上，亚马逊可能更胜一筹。这家零售巨头每天都在证明这一点。市场调研公司的数据显示，亚马逊网站推荐的销售转化率可以高达60%。 当亚马逊（Amazon）在网站上向你推荐商品时，它绝非无的放矢。 从根本上讲，这家零售巨头的推荐系统推荐的基础是一系列基本元素：用户过去购买过哪些商品；他们的虚拟购物车里有什么；哪些商品被他们评价或“赞”过；其它用户浏览及购买了哪些东西。亚马逊把这套自主研发的算法称为“从项目到项目的协同过滤算法”。依靠这套算法，亚马逊向回头客们提供了深度定制的浏览体验。数码爱好者们会发现亚马逊上满是新潮电子产品的推荐，而新妈妈们在相同的位置看到的却是婴幼儿产品。 亚马逊如今大获成功，推荐系统想必功不可没。2012年第二财季，亚马逊营收达到了128.3亿美元，与去年同期的99亿美元相比大涨了29%。毫无疑问，如此惊人的增长肯定离不开推荐系统。亚马逊将其深度整合到购物流程的方方面面，从商品发掘到结账付款，几乎无处不在。登录Amazon.com，你会看到许多商品推荐板块；点入某个商品的网页，“人气组合”与“（浏览了该商品的）用户还购买了其它商品”等栏目赫然在目。不过，亚马逊对推荐系统的效率守口如瓶。【亚马逊的一位发言人向《财富》杂志（Fortune）表示，“我们的任务是取悦用户，让他们在不经意之间发现美妙的产品。我们相信快乐每天都会出现，这是我们衡量成功的标准。”】 亚马逊还能通过电子邮件发送推荐。虽然亚马逊网站的推荐系统绝大部分依靠自动化，但至今仍有某些部分需要人工大量参与。亚马逊的一名员工表示，公司提供了许多软件，它们能根据用户的购买和浏览行为筛选目标用户。不过，最终目标的确认仍依靠人工而非机器。如果一名员工负责推销一部电影，例如《美国队长》（Captain America），那么他也许会想到其它类似电影，他要确保观看过别的卡通改编动作电影的用户都能收到亚马逊的邮件，以鼓励他们登陆亚马逊购买《美国队长》。 亚马逊员工研究邮件阅读率、点击率、退出率等关键参与指标——这可谓任何公司电子邮件营销渠道的标准做法——但鲜为人知的是，亚马逊按照邮件营收率等指标，对邮件生态系统进行优胜劣汰式优先级排序。一位员工对《财富》称：“这种功能很了不起。基本上，如果某位客户既有资格收到书籍类的推销邮件，又有资格收到视频游戏类的推销邮件，那么（亚马逊最终将向他发送）能带来平均营收更高的那类邮件。想象一下，在每一条产品线上，客户都有资格收到数十封电子邮件，但他们最终收到的只会是效果最佳的那封。” 这一策略能防止（客户的）收件箱被亚马逊的广告邮件塞满，同时将购买机会最大化。事实上，此类邮件的转化率和效率“非常高”，比网站推荐的效率要高得多。调研公司Forrester分析师苏察瑞塔•穆尔普鲁称，根据其他电子商务网站的业绩，在某些情况下，亚马逊网站推荐的销售转化率可高达60%。 虽然很多亚马逊观察员将推荐视为其杀手级应用，但分析师们相信它还有很大的提升空间。穆尔普鲁说：“电子商务行业的普遍看法是，亚马逊的推荐引擎是一个次优选项。”富国银行（Well's Fargo）分析师穆普鲁•特里沙•蒂尔表示，虽然亚马逊的推荐几乎无可挑剔，但在向用户提供相关性更高的产品方面，它仍有很多工作要做。比如说，她就收到过一封推销电锯便携箱的邮件。（但她并没有电锯。） 除了提升推荐本身的准确性外，亚马逊还可以探索更多争取用户的途径。目前，该公司已经开始销售之前都是成批出售的商品，比如说一副扑克牌或一罐肉桂，这些商品单独配送的成本过高。只有当客户订单金额大于等于25美元，才能购买这些商品。但在客户结账时，假如订单金额超过这一门槛，亚马逊可以积极推荐这些附加产品，这与传统超市在收银处摆放口香糖和糖果等冲动消费商品十分相似。 那时，亚马逊的顾客会想：“也没多几块钱。干吗不买呢？”和他们在超市的反应如出一辙。

坎儿井：Karez。

坎儿井是荒漠地区一特殊灌溉系统，普遍于中国新疆吐鲁番地区。

坎儿井与万里长城、京杭大运河并称为中国古代三大工程。吐鲁番的坎儿井总数达1100多条，全长约5000公里。坎儿井与万里长城、京杭大运河并称为中国古代三大工程，古称“井渠”。是古代吐鲁番各族劳动群众，根据盆地地理条件、太阳辐射和大气环流的特点，经过长期生产实践创造出来的，是吐鲁番盆地利用地面坡度引用地下水的一种独具特色的地下水利工程。 吐鲁番坎儿井，出现在18世纪末叶。主要分布在吐鲁番盆地、哈密和禾垒地区，尤以吐鲁番地区最多，计有千余条，如果连接起来，长达5000公里，所以有人称之为“地下运河”。“坎儿”即井穴，是当地人民吸收内地“井渠法”创造的，它是把盆地丰富的地下潜流水，通过人工开凿的地下渠道，引上地灌溉、使用。 坎儿井的结构，大体上是由竖井、地下渠道、地面渠道和“涝坝”（小型蓄水池）四部分组成，吐鲁番盆地北部的博格达山和西部 的喀拉乌成山，春夏时节有大量积雪和雨水流下山谷，潜入戈壁滩下。人们利用山的坡度，巧妙地 创造了坎儿井，引地下潜流灌溉农田。坎儿并不因炎热、狂风而使水分大量蒸发，因而流量稳定，保证了自流灌溉。坎儿井～

早在《史记》中便有记载，时称“井渠”。吐鲁番现存的坎儿井，多为清代以来陆续修建。如今，仍浇灌着大片绿洲良田。吐鲁番市郊五道林坎儿井、五星乡坎儿井，可供参观游览。 坎儿井的名称，新疆维吾尔语称为“坎儿孜”。伊朗波斯语称为“坎纳孜”(Kanatz)。苏联俄语称为“坎亚力孜”(k,lplItK)。从语音上来看，彼此虽有区分，但差别不大。中国新疆汉语称为“坎儿井”或简称“坎”。中国内地各省叫法不一；如陕西叫作“井渠”，山西叫作“水巷”，甘肃叫作“百眼串井”，也有的地方称为“地下渠道。”坎儿井是开发利用地下水的一种很古老式的水平集水建筑物，适用于山麓、冲积扇缘地带，主要是用于截取地下潜水来进行农田灌溉和居民用水。构造坎儿井是一种结构巧妙的特殊灌溉系统，它由竖井、暗渠、明渠和涝坝四部分组成。总的说来，坎儿井的构造原理是：在高山雪水潜流处，寻其水源，在一定间隔打一深浅不等的竖井，然后再依地势高下在井底修通暗渠，沟通各井，引水下流。地下渠道的出水口与地面渠道相连接，把地下水引至地面灌溉桑田。竖井先说竖井。竖井是开挖或清理坎儿井暗渠时运送地下泥沙或淤泥的通道，也是送气通风口。井深因地势和地下水位高低不同而有深有浅，一般是越靠近源头竖井就越深，最深的竖井可达90米以上。竖井与竖井之间的距离，随坎儿井的长度而有所不同，一般每隔20—70米就有一口竖井。一条坎儿井，竖井少则10多个，多则上百个。井口一般呈长方形或圆形，长1米，宽0.7米。乘车临近吐鲁番时，在那郁郁葱葱的绿洲外围戈壁滩上，就可以看见顺着高坡而下的一堆一堆的圆土包，形如小火山锥，坐落有序地伸向绿洲，这些，就是坎儿井的竖井口。暗渠暗渠，又称地下渠道，是坎儿井的主体。暗渠的作用是把地下含水层中的水会聚到它的身上来，一般是按一定的坡度由低往高处挖，这样，水就可以自动地流出地表来。暗渠一般高1.7米，宽1.2米，短的100—200米，最长的长达25公里，暗渠全部是在地下挖掘，因此掏捞工程十分艰巨。坎儿井始于西汉，而指南针在明朝时期才从中原传入西域，在开挖暗渠时，为尽量减少弯曲、确定方向，吐鲁番的先民们创造了木棍定向法。即相邻两个竖井的正中间，在井口之上，各悬挂一条井绳，井绳上绑上一头削尖的横木棍，两个棍尖相向而指的方向，就是两个竖井之间最短的直线。然后再按相同方法在竖井下以木棍定向，地下的人按木棍所指的方向挖掘就可以了。在掏挖暗渠时，吐鲁番人民还发明了油灯定向法。油灯定向是依据两点成线的原理，用两盏旁边带嘴的油灯确定暗渠挖掘的方位，并且能够保障暗渠的顶部与底部平行。但是，油灯定位只能用于同一个作业点上，不同的作业点又怎样保持一致呢？挖掘暗渠时，在竖井的中线上挂上一盏油灯，掏挖者背对油灯，始终掏挖自己的影子，就可以不偏离方向，而渠深则以泉流能淹没筐沿为标准。暗渠越深空间越窄，仅容一个人弯腰向前掏挖而行。由于吐鲁番的土质为坚硬的钙质粘性土，加之作业面又非常狭小，因此，要掏挖出一条25公里长的暗渠，不知要付出怎样的艰辛。据说，天山融雪冰冷刺骨，而工人掏挖暗渠必须要跪在冰水中挖土，因此长期从事暗渠掏挖的工人，寿命一般都不超过30岁。所以，总长5000公里的吐鲁番坎儿井被称为“地下长城”，真是当之无愧。暗渠还有不少好处是，由于吐鲁番高温干燥，蒸发量大，水在暗渠不易被蒸发，而且水流地底不容易被污染，再有，经过暗渠流出的水，经过千层沙石自然过滤，最终形成天然矿泉水，富含众多矿物质及微量元素，当地居民数百年来一直饮用至今，不少人活到百岁以上，因此，吐鲁番素有中国长寿之乡的美名。龙口龙口是坎儿井明渠、暗渠与竖井口的交界处，也是天山雪水经过地层渗透，通过暗渠流向明渠的第一个出水口。明渠涝坝暗渠流出地面后，就成了明渠。顾名思义，明渠就是在地表上流的沟渠。人们在一定地点修建了具有蓄水和调节水作用的蓄水池，这种大大小小的蓄水池，就称为涝坝。水蓄积在涝坝，哪里需要，就送到哪里。
