标题：探究参数方程在曲线绘制中的应用
摘要：本文主要探讨了参数方程在曲线绘制中的应用。首先介绍了参数方程的基本概念和原理，然后通过具体的实例分析了参数方程在绘制曲线时的作用。最后总结了参数方程在曲线绘制中的优势和局限性，并提出了进一步研究和应用的方向。
引言：参数方程是数学中一种描述曲线的方法，它通过给出曲线上每个点的坐标与一个或多个参数之间的关系，来确定曲线的形状。参数方程在曲线绘制中具有广泛的应用，可以描述各种各样的曲线，如直线、圆、椭圆等。本文将重点研究参数方程在曲线绘制中的应用，探讨其优势和局限性，以及未来的研究和应用方向。
正文：参数方程的基本概念和原理是本文的第一个重点。参数方程可以表示为x=f(t)，y=g(t)，其中t为参数，f(t)和g(t)是关于t的函数。通过改变参数t的取值范围，可以获得曲线上不同点的坐标值，从而绘制出整个曲线。参数方程的优点之一是可以方便地描述复杂的曲线，如椭圆。以椭圆为例，其参数方程可以表示为x=a*cos(t)，y=b*sin(t)，其中a和b分别为椭圆的长半轴和短半轴。通过改变参数t的取值范围，可以绘制出不同形状和大小的椭圆。参数方程还可以用来描述其他类型的曲线，如双曲线、抛物线等。
参数方程在曲线绘制中的应用是本文的第二个重点。通过具体的实例，可以更好地理解参数方程在绘制曲线时的作用。以心形曲线为例，其参数方程可以表示为x=16*sin^3(t)，y=13*cos(t)-5*cos(2*t)-2*cos(3*t)-cos(4*t)，其中t的取值范围为[0,2π]。通过改变参数t的取值，可以绘制出心形曲线的完整图像。在这个过程中，参数方程提供了一种简洁而直观的方式来描述复杂的曲线形状。参数方程还可以用来绘制其他有趣的曲线，如螺旋线、摆线等。
结论：参数方程在曲线绘制中具有一定的优势，可以方便地描述复杂的曲线形状。然而，参数方程也存在一些局限性，例如在描述封闭曲线时，可能需要额外的处理。未来的研究可以进一步探索参数方程在曲线绘制中的应用，例如将参数方程与计算机图形学相结合，实现更加灵活和高效的曲线绘制方法。

标题：参数方程在物理运动模拟中的应用研究
摘要：本文主要研究了参数方程在物理运动模拟中的应用。首先介绍了参数方程的基本原理和特点，然后通过具体的实例分析了参数方程在物理运动模拟中的作用。最后总结了参数方程在物理运动模拟中的优势和局限性，并提出了进一步研究和应用的展望。
引言：参数方程是数学中一种描述曲线的方法，通过给出曲线上每个点的坐标与一个或多个参数之间的关系，来确定曲线的形状。参数方程在物理运动模拟中具有广泛的应用，可以描述各种各样的物理运动，如自由落体、抛体运动等。本文将重点研究参数方程在物理运动模拟中的应用，探讨其优势和局限性，以及未来的研究和应用方向。
正文：参数方程的基本原理和特点是本文的第一个重点。参数方程可以表示为x=f(t)，y=g(t)，其中t为参数，f(t)和g(t)是关于t的函数。通过改变参数t的取值范围，可以获得物体在不同时间点的坐标值，从而模拟出整个物理运动过程。参数方程的优势之一是可以方便地描述复杂的运动轨迹，如二维抛体运动。以抛体运动为例，其参数方程可以表示为x=v0*cos(θ)*t，y=v0*sin(θ)*t-0.5*g*t^2，其中v0为抛体的初速度，θ为抛体的发射角度，g为重力加速度。通过改变参数t的取值，可以模拟出抛体在不同角度下的运动轨迹。参数方程还可以用来描述其他类型的物理运动，如简谐振动、圆周运动等。
参数方程在物理运动模拟中的应用是本文的第二个重点。通过具体的实例，可以更好地理解参数方程在物理运动模拟中的作用。以自由落体为例，其参数方程可以表示为x=v0*t，y=-0.5*g*t^2，其中v0为自由落体的初速度，g为重力加速度。通过改变参数t的取值，可以模拟出自由落体的运动轨迹。在这个过程中，参数方程提供了一种简洁而直观的方式来描述物体的运动过程。参数方程还可以用来模拟其他有趣的物理现象，如摆动、碰撞等。
结论：参数方程在物理运动模拟中具有一定的优势，可以方便地描述复杂的运动轨迹。然而，参数方程也存在一些局限性，例如在描述非理想情况时，可能需要考虑各种复杂因素的影响。未来的研究可以进一步探索参数方程在物理运动模拟中的应用，例如将参数方程与计算机模拟相结合，实现更加准确和真实的物理运动模拟方法。

Internship Report
I. Purpose:
First, to deepen understanding of profession, to confirm career preferences.
There are many ways to understand the career industry, for example, read related articles, consult the industry, but the most direct way is personally do the job. In the process of doing, you can determine whether you like the job and your own ability to perform. If you are competent, to find a job after graduation, you can use it as the target job; on the contrary, you must find a new direction for the work.
Second, to prepare the transition from student to profession.
It is often said, the university is an ivory tower. Indeed, there are great differences between the schools and the workplace, learning and work, students and staff. In the role of the transformation process, people's views, behavior, and psychological aspects have to make the appropriate adjustments.
Third, to enhance the competitive advantage when looking for work.
A company conducted a survey, xxxHow to choose an employer graduates.xxx Participating companies, including foreign, enterprises and private enterprises, the scale big and small. There is a topic so that they can choose the value, including schools, professional achievements, certificates, internship experience, social practice, accounts and so on. The results of different nature and size of the company have quite different focus, only one element is important for all companies, that is, job-related training and experience of candidates. So, if you have the relevant college internship experience in looking for work, there will be a great advantage.
II. Content:
During this month, with my father, I have got the chance to work as an intern in Tianjin Haiping Industry and Trade Company, which really excited me for a long time. The company is a start-up by my father’s friend, and it belongs to a micro-firm, so it only employed ten people or less.
After an brief self-introduction with the staff of the company, my internship started. It was my first time that I worked in a real company. I felt a little nervous because I had no idea of what kind of job I would take. As an English major student, I’m sure my knowledge of English is adequate for the job. And I have basic knowledge of foreign trade .So I think I just need to apply it into practice. During this time I worked as an assistant in the office, helped to deal with the language work, such as communicating with foreigners in English and translating the files between the companies. And I also did some daily and easy work because of my lack of work experience.
Then my first major task was handling phone lines, including incoming and outgoing phone calls in the front desk. Initially, I thought this task would be easy, after all it was just answering phone calls, but I quickly learned how much work had to be put into these phone calls. I realized that I had to better equip myself with the knowledge about the communication, be prepared for answering questionings, and memorize all the department extension as we were not allowed to reference any directory when transferring calls. Fortunately, after one week, I was able to grasp all the necessary requirements and I progressed a lot. In addition, during my first task as front desk personnel, I was exposed to other tasks, such as do some faxing and photocopying in company, preparing the material for the workmates, fetching newspaper or other documents for them. I had been doing that work almost a week. At the very beginning, I was so disappointed about what I was busy with. I was even so tired of them and gave it up. But when I saw the hard-working mates and some courage from my friends and leader, I moved on.
The following weeks, I switched gears and moved to the main office where I would spend the next two weeks in front of a computer, conducting research into different corporations in China that produce the similar products with our company. The process was not only time consuming, but complex and knotty as it involved a great amount of reading and recording. I managed to produce information, and communicate with customers and send e-mails. E-mail is the most common form of communication with customers. Therefore, we can use the knowledge about English correspondence for foreign trade we have learned in school. Many buyers or full-time purchasers simply judge your professionalism by your E-mail. Many customers also liked contacting with me on MSN or Skype, and they would ask for voice communication. At first I was nervous ,and I was always thinking about how to speak English in the right words and correct grammar. However, I found that they were not exactly strict to my English. As long as my oral English is enough to communicate and I know professional product knowledge, they can understand what I say. They are all outgoing but serious when talking about business.
Though hard and a little boring, I can be a part of the social society and enjoyed the pressure and competition from the outside world, quite different from the school yard. And also, many disadvantages and weakness have shocked me so much during the intern time. When I was blamed or criticized for my fault at first, I would try to argue with them and avoid my duty in the case. However, now, after such a long time training, I will be silent to accept what they teach me or scold me, and then self-question myself to make some changes. What I learned at school is so limited that I can hardly put into practice when faced with different complicated situations in society. So there is no doubt that I’ll read more and experience much to balance the book-knowledge and social life. And only in this way, can I be of importance to me, then to the country.
III. Gains:
“Study for the sake of use.” as a Chinese saying goes, I should say that there does exist a big gap between theories and practice. During this internship period, I have learned a lot of things that I can't get from our books:
First, it offers me an opportunity to get in touch with the things that I haven't encountered before. Many products of our company are stranger to us. Furthermore, I have broadened my horizons.
Secondly, the internship rightly provides me with a good chance to train my ability of communication and improve the spirit of teamwork. There are about ten employees in all. I didn't get acquainted with any of the other four, but in the first week, we got familiar with each other and shared information with each other. Also, when I encounter a difficult case, I'll also turn to the senior members of this department for help and they are always ready to help. Harmonious interpersonal relationship, right? Yes,a good relationship with our colleagues is priceless treasure to us as well as a strong sense of teamwork.
Thirdly, English is just a tool for communication. Therefore, as an English major student, we can't be limited to the study of the language but involve ourselves with knowledge of other areas. In the first few days, I always felt frustrated because there were so many new terms that I couldn't digest thoroughly. Although I can do very well in English reading, there are much desired for me to understand the situations provided by customers. However, practice makes perfect. With almost one-month practice, I now manage to handle the cases well. Knowledge, like the sea, is boundless; only through hard study can one reach the destination. It is completely right.
IV. Problems and Solutions :
The first one is related with the foreign trade terms. Such as quotation, ordering, terms of payments, out-factory preparation and payment. They are the most complicated and difficult issues. Because my major is not business English, I did not know the jargon and the professional name of our products at the beginning. I would read some books about International Trade to learn them by myself. And sometimes, I would ask others to explain them for me. The best solutions will be taken down into my note book. I know it does need some time to experience in handling such cases.
The second, my working attitude is not good enough. At first, I did not realize the seriousness of working. But I tried to correct my thoughts and focused myself on my work. But the members there did offer great help and teach me a lot of things.
The third, being shy is always my weakness. In fact, when I am with my friend, I am talkative. But during my work there, at first, I get nervous with the strangers.
The last but not least, my oral English is not good enough and I must practice it again and again to improve it. When I was talking with the foreigners I found that sometimes it was very hard to understand what they are talking about, not because of sick listening comprehension, but their accents, which really bothered me a lot. What we learned in the class is Standard English, so it is easy for us to understand each other. There are some customers’ pronunciation I cannot understand. One time, a client called me on Skype, so I found that he spoke very fast and I just can catch xxxHello!xxx Then I could not understand any word and I immediately told him I do not understand what he said, and then he typed while I speak. So I'll work hard to get a good command of oral English and listen to the pronunciation from different countries frequently. Thus I'll have a more fluent communication with my clients. Actually, I've been taken action right away. I try my best to make friends and chat with them from different countries. I'll work even harder.

20xx年就快结束，回首年的工作，有硕果累累的喜悦，有与同事协同攻关的艰辛，也有遇到困难和挫折时惆怅，时光过得飞快，不知不觉中，充满希望的年就伴随着新年伊始即将临近。可以说，年是公司推进行业改革、拓展市场、持续发展的关键年。现就本年度重要工作情况总结如下：
一、虚心学习，努力工作，圆满完成任务!
(一)在年里，我自觉加强学习，虚心求教释惑，不断理清工作思路，总结工作方法，一方面，干中学、学中干，不断掌握方法积累经验。我注重以工作任务为牵引，依托工作岗位学习提高，通过观察、摸索、查阅资料和实践锻炼，较快地完成任务。另一方面，问书本、问同事，不断丰富知识掌握技巧。在各级领导和同事的帮助指导下，不断进步，逐渐摸清了工作中的基本情况，找到了切入点，把握住了工作重点和难点。
(二)年工程维修主要有：在卫生间后墙贴瓷砖，天花修补，二栋宿舍走廊护栏及宿舍阳台护栏的维修，还有各类大小维修已达几千件之多!
(三)爱岗敬业、扎实工作、不怕困难、勇挑重担，热情服务，在本职岗位上发挥出应有的作用
二、心系本职工作，认真履行职责，突出工作重点，落实管理目标责任制。
(一)年上半年，公司已制定了完善的规程及考勤制度年下半年，行政部组织召开了年的工作安排布置会议年底实行工作目标完成情况考评，将考评结果列入各部门管理人员的年终绩效。在工作目标落实过程中宿舍管理完善工作制度，有力地促进了管理水平的整体提升。
(二)对清洁工每周不定期检查评分，对好的奖励，差的处罚。
(三)做好固定资产管理工作要求负责宿舍固定资产管理，对固定资产的监督、管理、维修和使用维护。
(四)加强组织领导，切实落实消防工作责任制，为全面贯彻落实“预防为主、防消结合”的方针，公司消防安全工作在上级领导下，建立了消防安全检查制度，从而推动消防安全各项工作有效的开展。
三、主要经验和收获
在安防工作这两年来，完成了一些工作，取得了一定成绩，总结起来有以下几个方面的经验和收获：
(一)只有摆正自己的位置，下功夫熟悉基本业务，才能更好适应工作岗位。
(二)只有主动融入集体，处理好各方面的关系，才能在新的环境中保持好的工作状态。
(三)只有坚持原则落实制度，认真统计盘点，才能履行好用品的申购与领用。
(四)只有树立服务意识，加强沟通协调，才能把分内的工作做好。
(五)要加强与员工的交流，要与员工做好沟通，解决员工工作上的情绪问题，要与员工进行思想交流。
四、加强检查，及时整改，在工作中正确认识自己。
(一)开展常规检查。把安全教育工作作为重点检查内容之一。冬季公司对电线和宿舍区进行防火安全检查。
(二)经过这样紧张有序的一年，我感觉自己工作技能上了一个新台阶，做每一项工作都有了明确的计划和步骤，行动有了方向，工作有了目标，心中真正有了底!基本做到了忙而不乱，紧而不散，条理清楚，事事分明，从根本上摆脱了刚参加工作时只顾埋头苦干，不知总结经验的现象。就这样，我从无限繁忙中走进这一年，又从无限轻松中走出这一年，还有，在工作的同时，我还明白了为人处事的道理，也明白了，一个良好的心态、一份对工作的热诚及其相形之下的责任心是如何重要
(三)总结下来：在这一年的工作中接触到了许多新事物、产生了许多新问题，也学习到了许多新知识、新经验，使自己在思想认识和工作能力上有了新的提高和进一步的完善。在日常的工作中，我时刻要求自己从实际出发，坚持高标准、严要求，力求做到业务素质和道德素质双提高。
五、要定期召开工作会议，兼听下面员工的意见，敢于荐举贤才，总结工作成绩与问题，及时采取对策!
六、存在的不足
总的来看，还存在不足的地方，还存在一些亟待我们解决的问题，主要表现在以下几个方面：
1对新的东西学习不够，工作上往往凭经验办事，凭以往的工作套路处理问题，表现出工作上的大胆创新不够。
2本部有个别员工，骄傲情绪较高，工作上我行我素，自已为是，公司的制度公开不遵守，在同事之间挑拨是非，嘲讽，冷语，这些情况不利于同事之间的团结，要从思想上加以教育或处罚，为企业创造良好的工作环境和形象。
3宿舍偷盗事件的发生，虽然我们做了不少工作，门窗加固，与其公司及员工宣传提高自我防范意识，但这还不能解决根本问题，后来引起上级领导的重视，现在工业园已安装了高清视频监控系统，这样就能更好的预防被盗事件的发生。
七、下步的打算
针对年工作中存在的不足，为了做好新一年的工作，突出做好以下几个方面：
(一)积极搞好与员工的协调，进一步理顺关系;
(二)加强管理知识的学习提高，创新工作方法，提高工作效益;
(三)加强基础工作建设，强化管理的创新实践，促进管理水平的提升。
在今后的工作中要不断创新，及时与员工进行沟通，向广大员工宣传公司管理的相关规定，提高员工们的安全意识，同时在安全管理方面要严格要求自己，为广大公司员工做好模范带头作用。在明年的工作中，我会继续努力，多向领导汇报自己在工作中的思想和感受，及时纠正和弥补自身的不足和缺陷。我们的工作要团结才有力量，要合作才会成功，才能把我们的工作推向前进!我相信：在上级的正确领导下，cssm大安防的明天更美好!

下面我将近几个月年来自己的工作、学习等方面的情况向大家做简要汇报：
一、严于律己，严格要求，遵章守纪，团结同志。
自到公司上班以来，我能严格要求自己，每天按时上下班，能正确处理好公司与家庭的关系，从不因个人原因耽误公司的正常工作;同时我也能严格遵守公司的各项规章制度，从不搞特殊，也从不向公司提出不合理的要求;对公司的人员，不管经理还是工人，我都能与他们搞好团结，不搞无原则的纠纷，不利于团结的事不做，不利于团结的话不说。
二、尽职尽责履行好自己的工作职责
我在公司主要从事财务工作，为此我从以下方面做了一些工作：
1、建立健全公司财务制度。公司成立以来，我是兼职会计，所以只负责每月的帐务处理和财务报表的报送，使得公司财务上的制度不够健全。自到公司正式上班后，我将财务人员的工作合理划分，在公司的财务方面按规定进行了要求，特别是发票管理方面，严格要求正确填开和索取，减少不必要的麻烦。在财务收支方面，严格执行公司的财经制度。
2、正确核算，按时结算，及时报送税务相关报表。在日常财务工作中，我能严格按财务规定正确核算公司的经营情况，按时结算有关帐务，每月末及时将财务报表和纳税申报表报送税务机关，没有因个人原因耽误报送时间。
3、及时将财务状况汇报于公司，积极为经理当好参谋。每个月我都将公司的财务情况给公司经理进行汇报，使经理能及时了解、掌握公司的经营状况，对经营中出现的问题我能及时提出合理化建议，发挥财务在公司经营中的作用，为建立当好参谋和助手作用。另外，对其他人员在销售、采购中有关不符合要求的做法，我也能及时提醒和指出。
4、认真负责，积极配合税务部门的稽查工作。10月初，税务部门对我公司进行稽查，在这期间，我能积极配合，并加强和稽查人员的配合，发挥自己的优势，多与他们沟通，对存在的问题与他们交流，争取他们的宽容，使公司的利益得到最大保护。
三、存在的问题
一年来，围绕自身工作职责做了一定的努力，取得了一定的成效，但与公司的要求和期望相比还存在一些问题和差距，主要是：自己来公司时间短，一些情况还不熟悉，尤其是对每个销售人员的核算，工程部分和零售部分没有明确划分清楚，给销售人员带来了麻烦，同时也给公司对每个销售人员完成任务的情况掌握不够准确。对这些问题，我将在今后的工作中认真加以解决。
最后，还想说三点：一是我的述职报告还不全面，有的具体的工作没有谈到，就今天我所谈的，希望大家多提宝贵意见。二是我工作能顺利的开展并取得较好的成绩，首先要感谢我的助手张晓莉，她对我的工作能积极给予配合和支持，任劳任怨，特别是在有身体不便的情况下，坚持上下班，帮我做了许多工作。同时，我还要感谢公司其他人员， 没有你们的支持和配合，就没有我们今天的工作成绩，你们是公司金字塔的基础。特别是在公司生产经营，销售盈利方面，你们精诚团结，积极为公司出谋划策，充分反映出我们公司员工是一支能吃苦、能奉献、能战斗、有进取精神的队伍。三是希望大家在明年，能一如既往地支持配合我的工作，我将一如既往地与大家一道，为公司获得更好的经济效益做出努力。

此次见习，我来到了联勤部幼儿园的小(1)班，幼儿园小班见习报告。在这里的两个星期里，我学到了很多东西，不光是平时的日常工作，这次我还有幸见识到了幼儿园的运动会和检查前的准备。
上次见习我就是来的联勤部幼儿园，上次是在中(1)班，那时我就感受到了小朋友们良好的行为习惯，从早上入园到晚上离园，都不用老师多说就能做 得很好。这次来到小班才知道，那些好的习惯是从小班时老师一遍一遍教的。早上做操时要让小朋友们先把小椅子推到桌子下面去才可以去站队;吃加餐前要先上厕 所、洗手，再搬着小椅子靠墙边坐着吃;玩玩具前要先给小朋友们讲好要求：1.要安安静静的玩 2.不可以抢其他小朋友的玩具 3.不能乱扔玩具，掉到桌子下面的玩具也要捡起来 4.说要收玩具的时候就安静的把每一个玩具放到筐子里，让玩具宝宝都回橱子里睡觉;喝水就站在一个地方喝，不可以跑到教室里喝;中午睡觉前要尽量自己脱裤 子，睡醒了要自己穿鞋;下午吃完饭要排好队等爸爸妈妈来接，叫到名字的才可以出来。这些都是很基本的，而小班是培养孩子形成良好习惯的地方，所以也是非常 重要的。
说到幼儿园的运动会，我觉得也让我感受到了很多。小孩子的天性就是活蹦乱跳的嘛，那把全园的小朋友都集中在一起举行一个体育活动，可想而知是比 较辛苦的。从准备道具到安排小朋友搬着小椅子下楼;从看其他年级的项目到完成自己班的项目，要想让孩子安安全全的进行完运动会，除了细心，还需要很多耐 心，实习报告《幼儿园小班见习报告》。还有一个地方让我记忆深刻——我们小班的项目是让小朋友们跑过来跳一下抓一个糖果，糖果是用玻璃纸包着报纸做的。小孩子很天真，不懂那只是道具，以为 是真的糖果。项目结束后，小朋友们都把玻璃纸拆开，翻着报纸问“老师，糖呢?老师，糖呢?”就在这一刻，虽然我知道这个社会中像道具这种东西有很多而且避 免不了，但我还是觉得心里不是滋味，觉得骗了善良、天真的小天使!
其实卫生每天都打扫，所以检查的时候卫生没有特意的做很多，就是装饰教室的时候有点需要动脑筋。也很感谢老师们这么信任我们，也让我们参与到了 装饰的行动中。贴画、剪纸、剪小花、摆桌子，虽然这些活都是些小活，但真的让我们积累了经验。只看到了结果与参与到过程中，就是有不一样的收获。看着变漂 亮的教室，感觉很不错，觉得我们虽然离开了，但是我们做的东西留下来了。
最后，还要说一下每个班里最重要，最辛苦，也是我们这次见习的重点的保育员老师。最重要是指保育员要负责小朋友们的人身安全，每一个可能发生危 险的动作都会想到，然后杜绝。有很多生活经验，有很多急救的知识也是我们需要学习的。最辛苦这一点，我们体会得到。每天要早到晚走，打水、提饭、擦桌子、 拖地，在小班还要喂喂饭，我们只是干了四分之一的活就觉得很累了，保育员平时一个人干，脑海中还要想到会不会出危险，真的很佩服她。
总之，在见习两周之内做过的事情我会牢牢记住，就算是一些微不足道的事情也会把它当作一种经验。而且在幼儿园里感觉净化了心灵，在学到了社会化东西的同时也多了一份相信美好的心。也很感谢班里的三个老师在无形之中教会了我们很多东西。
