Grandma lived in the countryside, where there were no cars and no tall buildings, but everything that was there made me mad. I got up early in the morning and came into the yard. There was silence and the air was very fresh. I sucked in the fresh air for fear of missing out on this wonderful time. 　　At about six o "clock, the sun was smiling. The cock crowed and urged people to get up quickly. In a few moments, the road in front of grandma"s house was busy - selling potatoes, corn, edamame... The roar of the car, the sound of the ring, and the sound of laughter, formed a brisk "country symphony." At noon the sun was burning the earth, and the seedlings hung their heads, and they rolled up their hands and lost their glory. Knowing that he was lying on the leaves of the leaves, he sang: "heat is dead, heat is dead." A few puppies were exposed to the sun, as if to say: "hot is dead, who can give me a cool bath?" At this time, the old people sat under the tree and talked, and we children ran up to the river in the mountains and swam. In the evening, the people who came home walked down the road, some of them barefoot. Some drove cattle, and sometimes they heard Shouting and whipping. 　　In a few moments, house and table were brought to the door, and the sky was wide open. The red glow of the horizon, the night breeze and the birds flying over the nest are their friends. They made a natural and harmonious pastoral landscape with the country family. At night, when the lights were out, the frogs sang "quack, quack, quack, quack, quack, quack, quack, quack." It was a beautiful song, and it was a lullaby to the people who had been working hard for the day. Every time the country has a unique and charming view.

中文名称：太阳能热水器 英文名称：solar water heater 定义1：把太阳能转换为热能以实现加热水为目的的装置。 应用学科：电力（一级学科）；可再生能源（二级学科） 定义2：吸收太阳辐射能将水加热的装置。 应用学科：资源科技（一级学科）；能源资源学（二级学科）　20世纪70-80年代，由于国家经济发展落后，人民生活水平较低，居民多用闷晒式热水器（汽油桶式、汽车油箱式等）。由于存在效率低，散热快，储水量少，冬季无法使用等缺点，现已退出市场。20世纪80—90年代，在国家相关部门支持和领导下，北京太阳能研究所开始从事太阳能热利用的研究，早期开发以平板式太阳能热水器为主。1984年，清华大学发明“磁控溅射渐变铝—氮/铝太阳选择性吸收涂层”，使太阳能集热管的大规模生产和商业化应用成为可能，直接催生了中国太阳能热利用产业化，使真空管式太阳能热水器成为适合中国国情的主力产品。 　　21世纪以来，中国太阳能热水器进入成熟阶段，产量与市场保有量一直保持快速增长。根据《中国太阳能热利用产业发展研究报告（2008-2010）》，2009年热水器年产量4,200万㎡，同比增长35.5%，其中4,000万㎡为真空管集热器，约占95%，社会保有量达到1.45亿㎡，同比增长16%，年节省能源约2,175万吨标煤，年减排二氧化碳约6,000万吨。2009年太阳能热水器生产量占世界78%，保有量占全世界54%。2010年中国太阳能热水器行业总产量达到4900万㎡。在中国95%以上的产品为全玻璃真空管式太阳能热水器。太阳能热水器行业是比较专业化的产业，目前已基本形成从技术研发、产品设计、原材料加工、设备制造、产品生产、检测认证、工程设计到营销服务的产业体系，带动了玻璃、金属、保温材料、机械制造、物流等相关行业的发展。

电热水器啊?我自己反正是不敢用电的..漏电没有预兆..用煤气的如果漏气还可以闻的到味道..漏电又看不见..危险...怕怕..

无能耗螺杆式空压机热水器，简称为空压机热水器，是一款新型高效的余热利用设备，它是100%靠吸收空压机废热来把冷水加热的，没有能源消耗。作为一种新型高效的余热利用设备，主要用于解决员工的生活、工业用热水等问题，因为企业本身就现在用螺杆式空压机，只是增加了螺杆空压机的功用，为企业节省能源的消耗，从而节省大量的成本。 节能原理： 空压机在工作过程中所耗电能转变热量后大部分被压缩后的油气混合物带走，这些混合物经过分离，分别在各自的冷却器（油冷却和气冷却）中被冷却介质（水或空气）带走，白白浪费了，从理论上讲，除了2%的辐射热和4%被气体带走的热量外，有94%的热量可以被回收的。 附上百度百科网址，想详细了解可以去看看，个人推荐志和这个牌子给你，我朋友的企业就用他们的，质量挺好的，好像他们是国内最早做空压机热水器的。

根据往年贵州公务员进面分数来看，平均进面分数在185——195分之间。今年贵州省考的笔试总分为300分，行测和申论各150分，申论为AB卷，笔试成绩占总成绩的60%，如果笔试分数在150-160分之间，那么除了特定的岗位，即你报考职位人数在个位数有进面机会外，大部分职位这个分数是没有进面机会的，这个分数在公务员所有考试分数中都是处于下线水准。预计今年进面概率大的笔试成绩须在180分以上，公务员笔试成绩180分是否进面，还需看同职位报考人数的多少。贵州公务员笔试成绩公式：笔试成绩=行政职业能力测验成绩+申论成绩。笔试成绩在“贵州人事考试信息网”公布。笔试成绩查分结束后，由省公务员主管部门确定“笔试环节成绩最低合格分数线”(“笔试环节成绩最低合格分数线”是指进入下一环节的笔试成绩与少数民族加分之和的最低成绩)。总成绩计算：总成绩按百分制计算。总成绩=(笔试成绩+少数民族加分)÷3×60%+面试成绩×40%。笔试、面试成绩和总成绩均按“四舍五入法”保留小数点后两位数字。同一职位报考人员总成绩名次出现末位并列的，笔试成绩高的报考人员进入下一环节，若笔试成绩相同的，以《行政职业能力测验》科目成绩高的进入下一环节。

这几篇不错 参考参考哦吧 I have some difficulty in learning English. For example, I can"t tell the difference between written English and spoken English. Sometimes I often make mistakes while speaking to others. Talking about English study,I think practice is necessary and important. For the improvement of English,we should practice as much as possible.Before classes,we must preview the lesson by repeating after the tapes and look up the new words in the dictionaries.When in class,we ought to try all our best to answer the teachers" questions.And it"s very useful to keep the texts in mind. Listening to english news also does good to our english.expecially in improving my spoken English. How to learnEnglish? Study English,You do need to use English with speakers who are not teachers of English This isn"t easy, since everyone feels constrained speaking English with friends with whom it would be natural to use a shared mother tongue Joining an English Club is a good idea and joining a club with an international membership is, for many people, even better If nothing like this is accessible, you might consider what would be involved in getting something going 活用英文乐趣多 活用英文乐趣多 你需要常常和英语教师以外的人士用英语交谈。这当然很不容易，因为与母语相同的人自由交谈时，彼此若用英语交谈总会觉得很不自在。亦可参加英语俱乐部或国际会员的俱乐部（至少有时使用英语沟通），这样对很多人而言更有益。如果没有合适的社团可加入，也不妨考虑任何足以提高英语能力的机会。 作文二: There are four key points to study English: listening, speaking, reading and writing Firstly, we should be brave to talk with others in English By doing this, we can improve ore talking and listening skill Secondly, we should try to listen to all kinds of English programmes as much as possible In this way, we can gradually improve our pronunciation Thirdly, we should often read English books When we e across a new word We should guess its meaning through the contest first Then look it up in the dictionary to have a check I thin,, it is a good way of reading Fourthly, we should practice our writing skills Whenever we have any idea, we should get the pen and write it down at once It is very important to avoid writing in Chinese way and using the Chinese grammar As long as we listen, speak, read and write more, we are sure to make remarkable progress!

爱情公寓评分最高的一季是《爱情公寓1》。豆瓣评分：《爱情公寓1》8分，共14.2万人。《爱情公寓2》7.9分，共10.9万人评价。《爱情公寓3》7.4分，共9.6万人评价。《爱情公寓4》7.3分，共9.6万人评价。《爱情公寓5》6.3分，共20.7万人评价。这是由韦正执导，陈赫、娄艺潇、孙艺洲、李金铭、赵霁、金世佳主演的都市青春喜剧。该剧讲述住在一幢普通青年公寓里的7个不同背景、不同身份、不同梦想的青年男女每天所发生的平常又乐趣十足的故事。主要信息：虽然表现的有些夸张，总是能让人捧腹大笑，很好的剧情，很真实的感觉，贴近生活，却也充满了闹剧的离奇，没有装腔作势。《爱情公寓》第二季则换了一种思维，它表面上也是都市白领日常生活的一些趣事，但实际很多时候表达出许多人生哲理，更重要的是，也不乏感动的镜头。在生活的某个领悟里，你只是一个新手小白、无名小卒而已，而那些擅长这个领域的大神就可以被认定为是真正的能者，真正的主角。其实不是这样的。一个人总会有自己擅长的领域。在这个方面你就可以被认定为主角。就像曾小贤，刚开始发现自己没有主角光环，于是就拿了不是属于自己的主角光环，到了最后才发现，其实也有一个属于自己的主角光环。

就是你在工作的时候做一些小工作,避免被老板发现!用来快速隐藏你做的小动作的快捷键!WIN+D快速显示桌面!WIN+m所有程序最小化! 详细的:winkey+d这是高手最常用的第一快捷组合键。这个快捷键组合可以将桌面上的所有窗口瞬间最小化，无论是聊天的窗口还是游戏的窗口……只要再次按下这个组合键，刚才的所有窗口就都回来了，而且激活的也正是你最小化之前在使用的窗口！winkey+m最小化当前所有窗口，但不能恢复，人称这个组合为“老板键”，就是在老板来的时候赶紧……winkey+f不用再去移动鼠标点“开始→搜索→文件和文件夹”了，在任何状态下，只要一按winkey+f就会弹出搜索窗口。winkey+r在我们的文章中，你经常会看到这样的操作提示：“点击‘开始→运行"，打开‘运行"对话框……”。其实，还有一个更简单的办法，就是按winkey+r！winkey+e当你需要打开资源管理器查找文件的时候，这个快捷键会让你感觉非常“爽”！再也不用腾出一只手去摸鼠标了！alt+tab如果打开的窗口太多，这个组合键就非常有用了。它可以在一个窗口中显示当前打开的所有窗口的名称和图标，选中自己希望要打开的窗口，松开这个组合键就可以了。而alt+tab+shift键则可以反向显示当前打开的窗口。小提示:winkey指的是键盘上刻有windows徽标的键。我看到留言中好多朋友不知道winkey键在什么地方,winkey键就在ctrl和alt键之间,记住:是键盘左边的ctrl和alt键.

精确制导武器的主要特点有以下3点：1.命中精度高精确制导武器命中概率可达80%以上，如制导炮弹，命中精度小于1米，而同类非制导炮弹则为30米。2.具有自主制导能力采用导引、控制系统或装置，调整受控对象的运行轨道，使之完成规定的任务。具有较强的抗干扰和机动作战能力。3.总体效能高总体效能体现在威力、射程、重量、尺寸、可靠性、全天作战能力等主要作战技术指标上。精确制导武器是采用高精度制导系统，直接命中概率很高的导弹、制导炮弹和制导炸弹等武器的统称。通常采用非核弹头，用于打击坦克、装甲车、飞机、舰艇、雷达、指挥控制通信中心、桥梁和武器库等点目标。扩展资料：发展趋势当前，精确制导武器的发展几乎融入了当今信息时代所有最新的科学技术， 特别是以信息技术为核心的高技术发展成果。世界一些地区的武装冲突 中几乎到处都有精确制导武器的身影，它正在将人类战争推向一个新的历史阶段。然而，精确制导武器并没有发展到顶峰，主要军事大国都在总结经验教训，力争进一步改进。系列化精确制导使用上的系列化，如反坦克导弹形成了近程单兵携带型和中、远程车载式及机载型体系。美军“空地一体”的空中反装甲作战中安 排了三个梯次的火力：4公里以内用 A H— I S“眼镜蛇”直升机发射陶式导弹； 5公里左右用 A H—64“阿帕奇”直升机发射“海尔法”导弹；距离远时由空军的 A—10攻击机发射“小牛”导弹。其二是同类精确制导武器的系列化，如防空导 弹已经形成了便携式、低空近程、中高空远程的系列。其三是精确制导武器自身 形成了不同型号的家族系列，如美军“宝石路”空地炸弹的导引头已经发展了三 代，空军的“响尾蛇”导弹发展改进了11个型号，“小牛”发展了7个型号，并广 泛采用了电视、激光、红外三种制导技术。智能化其实，的精确制导武器仍不如想像得高，只有50%—60%命中率 ，而提高其智能化水平后情况便大不相同了。主要做法是：（1）红外探测方式从点源探测向成像探测方向发展，以进一步提高目标探测的精度；（2）探测元件从 单元向多元方向发展；（3）采用多种制导头，以对付不同目标或者软件可调，以适应打击不同目标的需要；（4）采用复合制导技术；（5）信号处理电路由模拟式向数字化处理方向发展。精确制导武器远程化国外市场正在发展各种远射程的精确制导武器，目的之一便 是提高发射平台的生存概率。如美军正在研制“联合防区外发射武器”，并计划 将现有的“陆军战术导弹系统”（ ATACMS）的射程提高到150至250公里， 同时改进现有的“战斧”巡航导弹，增加射程，并采用GPS辅助制导等。其他 国家正在研制的防区外发射武器有：以色列的RAFACPOPERY（HAVENAP）导弹，射程100公里；法国射程为150公里的 A P A C H E子弹药散布器等。参考资料来源：百度百科-精确制导武器

「锄dee」的规则和玩法： 一．牌型 锄大地的出牌牌型有以下一些： 单张：任何一张单牌。 对子：二张牌点相同的牌。 三条：三张牌点相同的牌。 顺子：连续五张牌点相邻的牌，如「34567」「910JQK」「10JQKA」「A2345」等，顺的张数必须是 5 张， A 既可在顺的最后，也可在顺的最前，但不能在顺的中间，如「JQKA2」不是顺。 杂顺：花色不全部相同的牌称为杂顺。 同花顺：每张牌的花色都相同的顺称为同花顺。 同花：由相同花色的五张牌组成，但不是顺，称「同花」。如红桃「278JK」。 葫芦：例如：99955 。 铁只：例如：99995 。 二．牌的大小 1. 只有张数相同的牌可以比较大小，例如： 99 > 88 ， J > 10 ，但不能比较： 99 和 10 。 2. 单张牌的大小：首先比较牌点，如果牌点相同再比较牌的花色。牌点从大到小依次为： 2 A K Q J 10 9 8 7 6 5 4 3 。花色从大到小的顺序为：葵扇、红心、梅花、方块。比如： 9葵扇 > 9红心 > 9梅花 > 9方块 > 8葵扇 。 3. 其它牌型在进行比较时都取其中一张最大的牌按单张的方式进行比较：葫芦时，取三个中的最大一张。铁只时，取四个中最大的一张进行比较。顺子中最大的一张进行比较，注意 2 在顺子中作为小牌，如： 6 5 4 3 2 顺子比较时，只取 6 进行比较﹔ A 在和 K 相连作顺时，按大牌进行比较，在和 2 连在一起作顺时，作小牌处理。 4. 五张牌的牌型中，同花顺最大，铁只第二，葫芦第三，同花第四，杂顺最小。也就是说，上家出了杂顺后，你的任何一副同花、葫芦、铁只或同花顺都比杂顺大。 三．出牌规则 1. 第一副牌都由拿方块 3 的一方首先出牌，而且第一轮出牌中必须包含方块 3 。以后每副牌都由上副牌获胜者 ( 第一个打完手中牌的一方 ) 出牌，并且第一轮牌不需要包含方块 3 。 2. 首家可以出任何一种合法的牌型。 3. 首家出牌后，下家所出的牌张数必须和首家的相同，同时比首家所出的牌大﹔下家也可以 Pass 表示不出牌，由再下一家继续出牌。 4. 如果连续三家都 Pass ，这时最后出牌的一家可以重新打出新的牌型。 5. 如此继续，直到一人手中的牌全部打光为止 。 参考: QQ 每人派十三张牌 A最大 3最细 大围最大 之后红心 梅花 阶砖 可以出一只 二只 三只 五只 例如二只相同 三只相同连二只相同(夫佬) 五只连数字(蛇仔) 直至有一家出晒就是赢家 规则就系斗快出晒d牌，出晒果个就赢，咁另外果三个就叫输 2007-04-06 22:59:33 补充： 已经系最简单咁讲
