Chinese is the mother of encyclopedia. it's about learning well. improve sb's ability of expression. the exploration results of encyclopedia. can share it accurately. so that knowledge can be integrated into encyclopedia. inspire the exploration elite in the encyclopedia. develop in depth and breadth with in the undergraduate course. so that science and technology. push the great Renaissance in encyclopedia. mathematics is the nanny of encyclopedia. no matter which subject. all need the logical thinking of mathematical knowledge. today. I want to talk about the Application of mathematical knowledge in measurement. a person who does surveying work. we wall know coordinate conuersion and line coordinate calculation. this requires us to have a good knowledge of trigonometric functions. understanding and Application of polar coordinates in matrix and analytic geometry. only the flexible use of this knowledge. to achieve plane rotation and coordinate conversion. coordinate conuersion through coordinate forward calculation. the coordinates of any mileage point on the line can be calculated. and the coordinate azimuth of the tangent direction of the point. why do I give this example. because of the setting out of the spillway tunnel yesterday. reach the upstream outlet of intake gate foundation. lnlet walls on both sides in front of the gate. with the axis as the center. it is in a symmetrical figure eight shape. in fact. one side of each figure eight. the polar coordinate method is used to set the curve. just find the know conditions from the diagram. know the calculation process and complete the curve coordinate calculation. you can quickly find several equidistant points on the curve. connect these points to from an approximate curve. the more points you select. the more accurate the curve is. because the signal in the mountains is bad. it is more appropriate to select total station.
译，语文是百科之母，说的是学好语文，提高表达能力，将百科的探索成果，能够精准地分享出去，让知识能够融会百科，启发百科内的探索精英，向本科的深度开发，广度进军，从而将科学技术，在百科内推向伟大的复兴时代，数学则是百科的衣食保姆，无论哪科，都需要数学知识的逻辑思维，今天，我想说说数学知识，在测量工作中的应用。做测量工作的人，都知道坐标转换及线路坐标计算，这就要求我们有良好的三角函数知识，矩阵和解析几何中的极坐标概念的理解和应用，只有对这些知识的灵活运用，才能达到平面旋转，实现坐标转换，通过坐标正算实现坐标转换，并能算出线路上任意里程点的坐标，以及该点切线方向的坐标方位角，我为什么举这个例子，就是因为昨天泄洪洞放线，到达进水闸基础上游出口，闸门前两边进水墙体，以轴线为中心，呈对称八字形，其实，每八字形的一边，就是运用极坐标法测设曲线，只要从图中找到已知条件，知道计算过程，完成曲线坐标计算，便能很快找出曲线上几个等距点，连接这几个点即可成大致曲线，选择的点越多，曲线就越精确，因为山里信号不好，选择全站仪比较合适。
let me give another example of the use of mathematical knowledge in measurement. calculaate the mileage of each point on the plane curve. it is often encountered in engineering survey. on the transition curve of road turning. one middle pile point every10m. it is also understood by the surveyor. but what makes more sense. this is how I do it with mathematics people and machinery. during the day. my master yuan beichang and I measured on the National highway. in the evening. I listen to the arrangement of my leaders. at the construction site of wangzhuang new area. the asphalt paving team helped. by9p.m. the asphalt paving will be completed. the leader arranged xilihua to drive the roller back to Xichang road unit. annual maintenance of machinery tomorrow. from sinan to xibei. it goes around half of Wuxi city along National highway312. the two wheeled roller travels very slowly. the leader arranged me to go back to the dormitory with the roller. I sat next to her. she asked me as she opened. feeling of engineering survey. I took this opportunity to review the knowledge of measturement and mathematics. I told her that master yuan was amiable. because I'm in a National amateur school. tutored in mathematics. have a certain foundation. with the patience of the master. progress is fast. unconsciously. we passed guangfeng interchange. I pointed to a pile of stones on the roadside. there is pile between every four piles of stones. then. I told her about the points on the turning curve of the National highway. how is the mileage calculated. measuring plane curve by polar coordinate method. I can't do without high school mathematics knowledge. about mileage and reflection values. I recited the daytime calculus. she listened with admiration. study hard have time to help my children with their homework. I promised without thinking.
译，我再举一个测量中，运用数学知识的例子，推算平面曲线上各点里程，是工程测量中经常碰到，在道路转弯的缓和曲线上，每10米一个中桩点，也是测量人了解（的），但怎么做起来更有意义呢？我是这样与数学，人，机械联系起来做的，白天，我与师傅袁备昌在国道上测量，下班，我听从领导安排，到旺庄新区工地上，沥青摊铺班帮忙，到晚上9点，沥青摊铺结束，领导安排奚利华把压路机开回锡澄路单位，明天机械年度保养，这从锡南到锡北，沿312国道绕半个无锡城，两轮压路机行进又很慢，领导又安排我随压路机回单位宿舍，我坐在她身边，她边开边询问我，工程测量的感受，我趁此机会，将测量与数学知识温习一遍，我告诉她，袁师傅和蔼可亲，我由于在民族业余学校，补习了数学知识，有了一定基础，加上师傅的耐心，进步很快，不知不觉，我们过了广丰立交，我指着路边一堆推石子（说），每四堆石子之间，有一根桩，接着我向她讲述国道转弯曲线上各点，里程是如何推算（的），极坐标法测设平面曲线，没有高中数学知识是不行的，关于里程和偏角值，我把白天演算的背了一遍，她听得入神，羡慕地（说），好好学，有时间，辅导辅导我孩子功课，我不假思索的答应了。
she's tutoring her son in math. I deepened the essence of engineering. it is Application of mathematical knowledge in measurement technology. principle and method of contour representation of landform. elevation data of contour lines of hills and depressions. it is a series of equal difference numbers with positive or negative tolerance. first curve. count curve. inner curve. auxiliary curve. it is the best interpretation of the concept of probability. foundation trench excauation. it is the integration of measurement and volume calculation. I told her son. with the development of mathematical technology. lteration of measuring instruments. development trend of measurement technology. advanced mathematics has penetrated into surveying.we should keep pace with the times. continuous progress can cure all frustration and inferiority in life.
译，在辅导她儿子数学课程（中），我深化了工程测量工作实质，就是一项数学知识在测量技术中的应用，等高线表示地貌的原理及方法（中），山头和洼地的等高线的高程数据，就是一组公差为正或负的等差数列，首曲线，计曲线，间曲线，助曲线，更是对概率概念最好的诠释，基槽开挖，是测量工作和体积计算的融合……，我告诉她儿子，随着数学技术的发展，测量仪器的迭代，测量技术的发展趋势，高等数学已渗入测量工作中，我们要合着时代节拍，不断进步，才能治愈生活中的一切失意和自卑。
Application of mathematical knowledge in vegetable market. that's a measure of people's living standards. mathematical knowledge is used in science and technology . which is to measure the development level of science and technology. mathematical knowledge is used in engineering measurement. which is a comprehensive consideration of LQ andEQ. mathematical knowledge is the number axis to test our soul. at the starting point of becoming a person o. positive and negative depends on your choice.
译，数学知识，用于菜市场，那是测量人民生活水平，数学知识用于科技，那是测量发展水平，数学知识用于工程测量，那是智商与情商的综合考量，数学知识更是检测我们灵魂的数轴，在成为人的起点0，向正向负，就靠自己选择了！。
