两处高差为4.5-3.5=1.000m
由于读出n点的读数比m点的读数小,证明n点比m点高,所以就是多1m,即13m

高程测量中不能用水平面代替水准面.也就是说即使是在很短的距离内也应该考虑地球曲率对高程测量的影响.

因为你从起点转上100圈再测回起点,起点的高程也是不会变的,是相同的,因此高差绝对是零啊.而在实际测量中,由于误差的存在,闭合差就会不是零,因此要平差,消除误差.

测量高程其实也就是想求得两点的高差,所以可以用水平面代替水准面,测出的一般情况下,以平面代替椭球面忽略地球曲率影响的距离范围好像是100kM^2,

希望能够帮到楼主

楼主看我理解的对不对吧 感觉不是很明确
上面的45是指允许误差吧
一般水准路线的允许误差是 N倍根号L
L为全长
那现在N乘以根号15=45
可都N=3倍根号15
则5Km的允许误差应该为3倍根号15 乘以 根号5 =15倍根号3 ≈25.98mm
楼主看我理解的对么 要是对了 还望采纳回答

闭合水准路线高差闭合差等于所有测站高差全部相加.因为高差有正有负,测一圈以后闭合,总的高差的理论值应该等于零,但是由于测量存在误差,所以一般不可能刚好等于零.

推举采用闭合路线,闭合水准路线能更加准确地反应观测的质量.如果采用附合线路,每条线路都必须进行往返测,才能有效评价内附合精度（即观测精度）.

A blind man and a child
One night at a large shopping center,there was suddenly a power failure and it was all pitch dark.This caused a short period of chaos,before staff of the shopper center started to guide the panicked customers out of emergency exits with flashlights.
However,a blind man with a walking stick in his hand wasn't even aware of the power failure.Suddenly,he heard a child crying in one corner of the room.So he followed the sound and found the child."Why are you crying,kid," asked the blind man."My mother and I were separated after the power failure,and now I can't find her or the way out," the boy replied.
"Don't worry,I can guide you out," said the blind man.He took the hand of the child,and with the help of his walking stick,had almost no difficulty in finding the way out of the store.
"Thank God,I have finally found you," said the child's mother when she saw her son come out with the blind man.The mother and the boy were so excited that they both cried.
"Thank you,uncle,for your kind and timely help," the boy told the blind man."Now I should do something for you,too."
Though the blind man said there was no need,the boy and his mother insisted on escorting him back to his home.With their help,the blind man returned home much faster than usual.After that,he and the boy became good friends,and they often visited each other.

1.转点【turning point】:指的是中线测量时,因视线不能通视而增设的测站；水准测量时,为传递高程所设的过渡测点.
2.视准轴 :十字丝交点与物镜光心的连线,称为视准轴或视准线.
3.视线高程:是指视准轴到地面的垂直高度.通过视线高推算出待定点的高程.视线高程=后视点高程+后视读数.
4.水准高程,顾名思义,就是量测各点的高程

闭合水准路线是测量水平的,要测坐标的话得从其他地方引坐标过来.

我们的学校就在前进路.
一走进校园,就看见几座漂亮的教学楼耸立在眼前.
我们的校园美丽如画.南边有一个绿化小区,那里种了几棵棕榈树,风一吹,叶子“沙沙”地响,像一群婀娜多姿的姑娘在翩翩起舞.西边种了几棵凤凰树,11月份凤凰树开花了,火红火红的,灿烂极了.这时候,正好我们学校举行校运会,那火红的花儿,好像在为运动健儿打气呢!北边也种满了树木.站在楼上望去,一棵棵的绿树,一朵朵的红花,把我们的学校打扮得更美了!
瞧!这就是我们的教室.一台29寸的电视机吊在墙上角,老师的讲台上摆放着电脑和实物投影仪.老师上课时,利用这些先进的设备我们学起来就更容易了.告诉你吧,我们学校的考试成绩在市里是名列前茅.
告诉你一个秘密吧!在我们学校的阶梯室,你还可以看电影呢!因为阶梯室有一块大大的投影幕,配合一些先进的电化设备,我们就可以看到各种不同的电影.老师们还经常在这里上公开课呢!
凡是来过我们学校的人,都会竖起拇指夸奖我们学校――真棒!

啊啊啊啊啊啊啊啊啊啊啊啊啊?英文?烦人

当天空变成幽蓝的眼睛,城市就成为一座孤独的岛屿,忧伤如海浪轻轻拍打夜的梦境.
一个季节就在蓦然回首时降临了.
那些白色花朵如同翩飞的蝶,一朵,一朵,在我的发辫和肩头怒放,就如年轻的恋情在春天争相吐艳；它们飞翔的姿势里有音乐传出,就如年轻的身体是一朵会唱歌的花.
那满天白色的称为“雪”的花啊,仿佛受伤的羽毛纷纷扬扬,零乱得这样惊心动魄,是谁在同命运搏斗?
我伸手抚摩这些怀着疼痛的羽毛,而化在掌心的,是一颗清的泪和一声轻的叹息.
宽容的土地将拥她们入怀,无论腐或盛、泣或笑,都在土壤里孕育成种子,在春天里萌芽.
挫折与磨难,有时是生命财富的沃土和雨水.
我们拼搏过了,忍耐过了,才能面对寒冷,在漫天大雪的天气里,感动地说：“啊,那是生命的花朵.”

A Camp
Today we go to Huang Mountain to camp.Our teachers take all the pupils in our third class.We arrival there at 10am.Then we start to climb the largest mountain.After 2 hours,we arrive the top.All of us are very tired.Then the teachers ask us to have a rest.We take out the food we bring our own.After lunch,we play games and take photoes .At 3pm,the teachers say we must go back.We are too tired to walk down,so we decide to take cable car to go down.It is a interesting day,isn't it?

水平面是想象当中完全水平的一种面
水准面是想象当中与地球所有铅垂线都垂直的曲面,因为地球内部密度分布不均匀,所以并不是所有铅垂线都像想象当中的垂直线一样,所以,这个曲面就总体而言是个坑坑洼洼的椭球面.

There are always many failures and difficulties in our life.They may let us down ,cast us down ,even break us down !However,we are forced to face to them no matter how we are fed with them and how we are annoied with them.So the most import thing we need is to be confident in ourselves.Only with confidence can we face to failures!
Firstly,it is you who is suffering difficulties that have the ability to deal with your teouble perfectly.the first thing you should do is to believe in yourself!Everyone can not know the result until they have a try on the problem.Just like Edison can not invent anything with no experiment.His success is based on his bravery to face to failures.So.if you have the same spirit,you may become another Edisone!Dear friends,why couldn't you be brave to face faiulures and difficulties?
Secondlyly,it is you who can seise the key to the problem that make life more colourful.Assune that if William Henry Gates III KBEIt (威廉·亨利·盖茨三世爵士)haven't seized the opportunity to develop microsoft and he haven't had the belief that he must make it,the reliable fact is that he is an old poor out of work man now.So when you think you can't do anything,you are the poorest person in the whole world,please ask yourself:Do you always in impasse like Gates?Think about others and ask yourself:Do you always face to choose being alive or death like American soldiers?Do you always afraid of starving to death like African children?The answer is:No!Cmpared with them,you are so lucky and happy a person !Dear frinds ,why couldn't you belive you can seize the right chance to win back your success,and live a colourful life?

1.勤查字典,结合注解弄清楚课文里每个字的意思.记住,不能只看注解,一定要查字典,因为注解有的是解释特定语境下的字义.字典的话,推荐商务印书馆出版,由王力先生原主编,蒋绍愚增订的《古汉语常用字字典》第四版.2.把学过的字词进行归类总结,弄清楚同一个字的不同意义,并收集例句,经常复习.重点18个虚词：而何乎乃其且若所为焉也以固于与则者之.3.把学过的课文反复诵读,直至背诵.注意两点:不要死记,一定要通过反复诵读达到背诵的程度.诵读的时候注意断句和字词的含义.

我没明白你说的意思,沉降观测要的是每次观测与上次观测的差值,三个点说的是三个基准点,这三个点要在同一系统内,设三个点是为了有一点破坏了还可以用起他的点观测和检核!

倒三角最上的线（三角形三边,上面的边）就是水准点.
谁设的点问他这个点的海拔高度是多少,在图纸中换算出这个点的标高相当于建筑标高的多少.

全站仪的精度和水准仪和经纬仪比较.精度相对低点.
另外误差和棱镜以及操作 有关系的

三个分式通分得：400/30 408/30 375/30
所以吴师傅效率高

P表示弧度化为秒的乘常数：1弧度=180*3600/π=206264.806秒≈206265秒.一些计算的过程中必须通过乘这个常数将弧度单位化为秒.

一、制定复习计划,增强复习计划性
“工欲善其事,必先利其器”.意思是说无论做什么事,都要事先做好准备.期末复习是期末考试取得好成绩的有力保证,每位学生应在思想上高度重视,不能马虎应付,你在制定复习阶段计划时必须弄清以下几个问题：复习时间、考试内容、考试时间,然后制定自己的复习计划和每天学习时间安排,以便在有限的时间内复习完全部复习内容,增强复习的计划性,每天对计划完成情况进行简单的检查分析,落实复习计划,确保复习的质量.
二、讲究复习方法,提高复习效率
1、扎实基础知识,落实基本技能.在自己主动复习时,要注意回归教材,精读课本,扎实掌握基础知识和基本技能.安排一部分课余的时间对各科基础知识进行主动复习,内容一项一项地整理、归纳,真正搞清楚,弄明白.在复习过程中,要充分发挥自己的学习主动性,自己找规律、抓特点,对所学知识进行归纳和总结,使之条理化和系统化,内化成自己的知识；对于自己不会的知识点要主动向老师或同学同学请教,不要放过每一个疑点,不遗漏每一个重点,不忽视每一个考点.
2、强化能力训练,主动查漏补缺.在复习基础知识和落实基本技能的基础上,再加强能力测试题型的解题思路和解题技巧的训练,对能力测试题型存在的缺漏进行补强,弄清“会了什么?”、“还有什么不会?”,发现疑难薄弱,采取同题练习,重点突破,提高综合解题能力,以求尽善尽美.查漏补缺可以看错题集,温故知新,避免一错再错.期末复习时将自己平时归纳整理的错题集和以往的考试卷拿出来看一看,研究曾经出现的问题,了解出错的症结,以免重蹈覆辙.实践证明,考前看错题集,是一种非常便捷有效的复习方法.
3、重视模拟训练,提高解题能力.学校老师编印的期末综合练习是老师根据各科考试要求而编印有针对性的模拟试卷,主要是供我们复习使用,试题绝不能拿过来做一遍,一对答案了事.而应该在全面复习的基础上再做模拟试卷,并按期末考试的要求独立完成,养成认真审题、规范书写、细心检查的习惯,做到不看错题、不漏题、不误答、不潦草,以减少失误.做完后核对答案,进行试卷分析,查漏补缺,对考试中存在的不足,必须在期末考前自己主动做好整改.对试卷作分析时注意回答以下三个问题：“考试成功在哪里?不足在哪里?今后怎办?”.最后再做一至两套期末考试模拟试题,熟悉考试题型,提高解题速度和综合解题能力.
三、讲究应考技巧,提高考试成绩
在考场上要有暗自鼓励的习惯,相信自己能行,以良好的心理状态投入考试,先浏览全卷,弄清题量,遵循由易到难,合理安排解题速度,每分志在必得,会做一定做全对,不会做乱乱作；别人会做的我要做对,别人不会做的我能做些.
老师们、同学们,一分耕耘一分收获,只要大家按复习计划主动复习,讲究复习方法,师生积极配合,期末考试一定会取得好成绩!
今天我们在新圩中学的沃土上播种希望和理想,明天我们一定会在这里收获成功和辉煌；
最后,祝全体师生在虎年里：虎气冲天嗷嗷叫,生活幸福哈哈笑；牛年成绩还不坏,虎年
一、思想重视
期末复习是期末考试取得好成绩的有力保证,首先,应在思想上重视它,不能马虎麻痹.因为期末考试考查面涵盖一本书的内容,全面检测我们的能力,是检验我们一学期学习效果的主要形式之一.学习半年了,究竟学得怎么样?学生自己想知道,老师、家长也想知道.而这个效果可以通过考试来检验.“复习”不是可有可无,要下功夫搞好.
二、讲究方法
俗话说：工欲善其事,必先利其器.意思是说无论做什么事,都要事先做好准备.期末考试也是一样.要想取得好成绩,除了平时努力学习,打好基础,提高能力外,期末复习方法也很关键.复习方法多种多样,应该根据自己的实际情况,选取科学、高效的复习方法.这里向大家重点推荐一种复习法.
1、按照“循序渐进、阶段侧重、精讲精练、知能并存”的原则,把期末复习分成四个阶段：（1）基础复习；（2）强化能力；（3）查漏补缺；（4）模拟练习.
2、拿出一半的时间进行基础知识复习.对这些内容一项一项地归纳、整理,真正搞清楚,弄明白.然后,侧重能力测试题型的解题思路、技巧的练习.在此基础上,进行查漏补缺,以求尽善尽美.最后做两套期末考试模拟试题,熟悉考试题型、考场规则.四个阶段,四个方面,环环相扣,逐步深入,四位一体,一气呵成.
3、在复习过程中,要充分发挥学生自己的学习积极性,在老师的指导下,自己归纳、总结,找规律,抓特点,和同学一起讨论、研究,不放过每一个疑点,不遗漏每一个重点,不忽视每一个考点.
三、巧用试题
每位教师手里都有自己的期末练习题,还有学校订购的单元检测与期末复习题,期末复习题主要是供我们复习用,试题绝不能拿过来做一遍,一对答案了事.应先按上面讲的前三个阶段,逐项进行复习,然后再做题.做完后核对答案,发现问题,查漏补缺.最后,按期末考试的要求,独立完成“期末测试题”,起到事半功倍的效果.
这个不行啊

不一定通过几何中心,但一定通过地球的重心,因为重心一定在重力的作用线上.而地球内部密度很不均匀,所以地心与地球重心不会重合.
补充说明,即使地球是圆球体,只要密度不均匀,也还是不能通过地心.

四舍五入 取三位小数把V和FH的差值分配到最长的之水准线路上,再说了 即使二等水准测量也符合要求啊!间接平差以后就很接近真实值了!

During Winter holidy
I often went to see my grandma and grandpa during winter holidy. They are both seventy years old and live in the country happily. I can do many interesting things there. I was used to getting up early in the morning and breathing the fresh air in the countryside. After snow, I would like to skate and ski with my friends. When night came, I was used to sitting by the fire and listening to grandma telling me many funny stories. And I told her some new things happening in the city. When I had to go back, I was always reluctant to go. I really felt happy living in the country. I wish my summer holiday come soon.
在寒假,我常无看望爷爷奶奶.他们都70岁了,住在乡下,过得很幸福.在那里我可以做很多有趣的事情.在早上我通常起的很早,呼吸着乡下的新鲜空气.下雪之后,我就特别喜欢和我的朋友门去滑雪.夜幕降临的时候,我通常是坐在火炉边,听奶奶给我讲很多有趣的故事.我也给她讲一些发生在城市里的新鲜事情.但我要返回的时候,我一直念念不舍,不愿离开.在乡下,我过得很愉快.我期待暑假的到了.
