1、電大知識產(chǎn)權(quán)法考試資料形成性考核冊作業(yè)1一、名詞解釋（每小題2分，共20分）1、知識產(chǎn)權(quán)法：知識產(chǎn)權(quán)法是調(diào)整因創(chuàng)造、使用智力成果而產(chǎn)生的，以及早確認(rèn)、保護(hù)和形式治理成果所有人的知識產(chǎn)權(quán)的過程中所發(fā)生的各種社會關(guān)系的法律規(guī)范的總稱2、商品裝潢：是指在商品或其包裝、容器以及其他附著物上所進(jìn)行的裝飾。3、商品商標(biāo)：指使用于商品之上的商標(biāo)，根據(jù)使用者的不同，分為制造商標(biāo)和銷售商標(biāo)。4、證明商標(biāo)：也稱保證商標(biāo)，是指由對某種商品或服務(wù)具有檢測和監(jiān)督能力組織所控制，而由其以外的人使用在商品或服務(wù)上，用以證明該商品或服務(wù)的原產(chǎn)地、原料、制造方法、質(zhì)量、精確度或其他特定品質(zhì)的商品商標(biāo)或服務(wù)商標(biāo)。5、注冊商標(biāo)：經(jīng)

2、國家商標(biāo)主管機(jī)關(guān)核準(zhǔn)注冊的商標(biāo)。二、簡答題（每小題10分，共40分1、請按你的理解給知識產(chǎn)權(quán)概念下個定義。答：知識產(chǎn)權(quán)是治理成果所有人和使用人給予自己所擁有的智力成果而依法享有的各項民事權(quán)利的總和，包括著作權(quán)、商標(biāo)權(quán)、專利權(quán)、閥線圈、發(fā)明權(quán)以及其他科技成果權(quán)。知識產(chǎn)權(quán)是一個隨著科學(xué)技術(shù)、文學(xué)藝術(shù)的發(fā)展而不斷拓展和深化的概念2、請試述知識產(chǎn)權(quán)的法律性質(zhì)。知識產(chǎn)權(quán)是一種無形財產(chǎn)權(quán)，是一種特殊的民事權(quán)利，這就是知識產(chǎn)權(quán)的法律性質(zhì)。3、請試述知識產(chǎn)權(quán)的范圍。知識產(chǎn)權(quán)的范圍，有廣義和狹義兩種。廣義的知識產(chǎn)權(quán)范圍，為兩個主要的保護(hù)知識產(chǎn)權(quán)的國際公約所界定。第一：1967年簽訂的世界知識產(chǎn)權(quán)組織公約指出，知

3、識產(chǎn)權(quán)應(yīng)包括下列權(quán)利：1關(guān)于文學(xué)、藝術(shù)和科學(xué)作品的權(quán)利；2關(guān)于表演藝術(shù)家的表演、錄音和廣播的權(quán)利；3關(guān)于人類在一切領(lǐng)域內(nèi)的發(fā)明的權(quán)利；4關(guān)于科學(xué)發(fā)現(xiàn)享有的權(quán)利；5關(guān)于工業(yè)品外觀設(shè)計的權(quán)利；6 關(guān)于商品商標(biāo)、服務(wù)商標(biāo)、商號及其他商業(yè)標(biāo)記的權(quán)利；7關(guān)于制止不正當(dāng)競爭的權(quán)利；8其他一切來自工業(yè)、科學(xué)及文學(xué)、藝術(shù)領(lǐng)域的智力創(chuàng)作活動所產(chǎn)生的權(quán)利。第二：1995年1月1日成立的世界貿(mào)易組織（WTO）的與貿(mào)易有關(guān)的知識產(chǎn)權(quán)協(xié)議規(guī)定的范圍，包括：1版權(quán)與鄰接權(quán)2商標(biāo)權(quán)3地理標(biāo)志權(quán)4工業(yè)品外觀設(shè)計觀5專利權(quán)6集成電路布圖設(shè)計權(quán)7未公開的信息專有權(quán)，主要是商業(yè)秘密權(quán).目前基本上國際上都是以這兩個協(xié)議所界定的范圍為

4、知識產(chǎn)權(quán)的范圍。 狹義的知識產(chǎn)權(quán)，指傳統(tǒng)意義上的知識產(chǎn)權(quán)，即專利權(quán)、商標(biāo)權(quán)、著作權(quán)。卓越人社區(qū) o4你認(rèn)為知識產(chǎn)權(quán)法有哪些作用（最少四條）。 答：（1）為智力成果完成人的權(quán)益提供了法律保障，調(diào)動了人們從事科學(xué)技術(shù)研究和文學(xué)藝術(shù)作品創(chuàng)作的積極性和創(chuàng)造性。（2）為智力成果的推廣應(yīng)用和傳播提供了法律機(jī)制，為智力成果轉(zhuǎn)化為生產(chǎn)力，運(yùn)用到生產(chǎn)建設(shè)上去，產(chǎn)生了巨大的經(jīng)濟(jì)效益和社會效益。（3）為國際經(jīng)濟(jì)技術(shù)貿(mào)易和文化藝術(shù)的交流提供了法律準(zhǔn)則，促進(jìn)人類文明進(jìn)步和經(jīng)濟(jì)發(fā)展。（4）知識產(chǎn)權(quán)法律制度作為現(xiàn)代民商法的重要組成部分，隊對完善我國法律體系，建設(shè)法治國家具有重大意義。三、案例（40分）某公司新生產(chǎn)一種環(huán)保型

5、純天然礦泉水。經(jīng)試銷顧客反響很好，銷售業(yè)績不斷上升，為防止他人假冒并樹立市場形象，取得信譽(yù)，公司決定申請商標(biāo)注冊。公司想起名注冊商標(biāo)為“神怡”，但又怕別人利用法律侵害其商標(biāo)權(quán)益，如何注冊也不清楚。如果你作為商標(biāo)代理人將提出哪些建議，并提供注冊咨詢服務(wù)。要求：寫一篇咨詢意見書（包括怎樣注冊、程序是什么、如何防止權(quán)益被侵害、可采取哪些方案。）根據(jù)我國商標(biāo)法及相關(guān)法規(guī)，我作為商標(biāo)代理人，謹(jǐn)對貴公司申請“神怡”牌礦泉水注冊商標(biāo)一事，出具咨詢意見如下： 一、 怎樣申請注冊商標(biāo)及申請程序。我國商標(biāo)法規(guī)定，我國國內(nèi)申請人可以通過兩種渠道辦理商標(biāo)注冊，一是由申請人委托商標(biāo)代理機(jī)構(gòu)代為辦理注冊商標(biāo)申請事宜，二是

6、由申請人直接辦理。貴公司可以選擇其中之一進(jìn)行辦理。若選擇委托辦理，貴公司首先應(yīng)當(dāng)注意選擇具有商標(biāo)代理資質(zhì)的商標(biāo)代理機(jī)構(gòu)就代理事項與之協(xié)商一致，簽訂委托代理合同，出具授權(quán)委托書，并向該機(jī)構(gòu)交納代理費(fèi)以及貴公司企業(yè)法人營業(yè)執(zhí)照等有效證件的復(fù)印件。若選擇直接辦理，則應(yīng)持企業(yè)介紹信、企業(yè)法人營業(yè)執(zhí)照及有關(guān)申請文件，直接到商標(biāo)局辦理注冊商標(biāo)申請手續(xù)。無論采用哪種渠道，都必須填寫統(tǒng)一的商標(biāo)注冊申請書報商標(biāo)局，并提交商標(biāo)圖樣及申請人身份證講的復(fù)印件。商標(biāo)局在收到商標(biāo)注冊申請之后，將依法對該申請進(jìn)行形式審查和實質(zhì)審查，經(jīng)審查，對符合規(guī)定的，予以初步審定并予以公告。自公告之日起三個月內(nèi)無異議者，予以核準(zhǔn)注冊。對

7、不符合規(guī)定的，予以駁回。申請人不服的，可以自收到駁回通知之日起15日內(nèi)向商標(biāo)復(fù)審委員會申請復(fù)審。對復(fù)審結(jié)果不服的，可以自收到復(fù)審結(jié)果通知書之日起30日內(nèi)向人民法院起訴。二、 關(guān)于防止貴公司合法權(quán)益受損害的措施這個問題的實質(zhì)是貴公司一旦獲得“神怡”牌礦泉水注冊商標(biāo)后，應(yīng)采取哪些措施予以保護(hù)的問題。關(guān)于商標(biāo)保護(hù)，我國法律規(guī)定主要有行政保護(hù)和司法保護(hù)兩種方式。行政保護(hù)是指商標(biāo)管理機(jī)關(guān)通過行政程序依法查處商標(biāo)侵權(quán)行為來保護(hù)商標(biāo)專用權(quán)。貴公司一旦發(fā)現(xiàn)自己擁有的注冊商標(biāo)權(quán)益受到損害，如市場上出現(xiàn)假冒產(chǎn)品，就應(yīng)當(dāng)及時向商標(biāo)管理機(jī)關(guān)報告，并積極搜集相關(guān)證據(jù)，配合商標(biāo)管理機(jī)關(guān)打擊任何人對貴公司注冊商標(biāo)合法權(quán)益的

8、侵權(quán)行為。司法保護(hù)是指司法機(jī)關(guān)通過司法程序依法審理商標(biāo)侵權(quán)案件，制裁商標(biāo)侵權(quán)人，打擊假冒注冊商標(biāo)犯罪來對商標(biāo)專用權(quán)予以保護(hù)。如有必要，貴公司依法直接向人民法院起訴，請求司法保護(hù)。此外，貴公司也應(yīng)加強(qiáng)注冊商標(biāo)自我保護(hù)，包括通過學(xué)習(xí)增強(qiáng)商標(biāo)保護(hù)意識，配備商標(biāo)管理人員，采取各種預(yù)防措施，發(fā)生侵權(quán)事件后及時請求行政保護(hù)和司法保護(hù)等。商標(biāo)事務(wù)所商標(biāo)代理人：年 月 日知識產(chǎn)權(quán)法形成性考核冊作業(yè)2王某在黑龍江省齊齊哈爾市于1990年4月1日向中國專利局受理處有幾名為“保溫鞋”的實用新型申請文件，郵戳日為1990年4分月1日，中國專利局受理處收到該申請文件的日期為1990年4月6日。李某在北京于1990年4月

9、2日向中國專利局額受理處直接遞交一份與王某同樣的發(fā)明創(chuàng)造的專利申請文件，也名為“保溫鞋”的實新型專利申請。 問：如何處理？為什么？答：本題的考點(diǎn)是依法判斷王某與李某誰是該項專利的最先申請人，該項專利的申請權(quán)應(yīng)當(dāng)歸誰所有。我國專利法規(guī)定，兩個以上主題相同的發(fā)明創(chuàng)造分別向?qū)＠姓块T提出申請的，實行先申請原則。即誰是最先申請人，誰就是請求權(quán)人。確定的方法是，以申請日作為申請時間先后的判斷標(biāo)準(zhǔn)，以國務(wù)院專利行政部門受到專利申請文件之日為申請日，但是申請文件是郵寄的，以寄出的郵戳日為申請日。在本題中，王某是以郵寄方式申請的，郵戳日是1990年4月1日，因此他的申請日依法應(yīng)確定為1990年4月1日。而李

10、某是以直接遞交方式申請的，遞交時間是1990年4月2日，申請日為1990年4月2日。由此可見，王某是該項專利的最先申請人，因此國家專利局應(yīng)確定該項專利的申請權(quán)歸王某所有。 知識產(chǎn)權(quán)法形成性考核冊作業(yè)3案例答案要點(diǎn)：關(guān)于故宮博物館國務(wù)院和某出版社糾紛的案例，考核的是分析問題、解決問題的能力。要求寫以原告的代理人身份寫一篇代理意見和以被告的律師身份寫一篇答辯意見。本題無標(biāo)準(zhǔn)答案，只要言之有理，能自圓其說，予以發(fā)揮即可 代理意見參考要點(diǎn)：我受某某律師事物所委托，擔(dān)任原告故宮博物館的代理人，現(xiàn)根據(jù)民法通則和著作權(quán)法等法律法規(guī)的規(guī)定，以事實為基礎(chǔ)，以法律為準(zhǔn)繩，發(fā)表以下代理意見： 1、故宮博物館將900

11、多套珍貴文物進(jìn)行攝影、測量，編寫文字形成作品并經(jīng)過“兩家出版社”出版，從而享有該作品的著作權(quán)。理由：（1）被告非法使用的原告790張圖片是經(jīng)過原告故宮博物館對文物進(jìn)行攝影、編寫文字而成，原告對每一張圖片享有攝影作品的著作權(quán)。（2）原告對900多張圖片配以文字，予以整理編輯，擁有對900套圖片文字匯編而成的匯編作品即出版物的著作權(quán)。 2、出版社侵犯了故宮博物館的著作權(quán)，構(gòu)成了權(quán)利的侵犯，應(yīng)當(dāng)賠禮道歉，賠償損失。理由：（1）出版社未經(jīng)原告許可，擅自使用其圖片，不僅是一種剽竊抄襲的侵權(quán)行為，而且是一種未經(jīng)著作權(quán)人許可，以營利為目的，復(fù)制發(fā)行原告作品的侵權(quán)行為。結(jié)合教材283頁內(nèi)容。被告的行為侵犯了原

12、告的使用權(quán)，不屬于著作權(quán)法中合理使用的情形。結(jié)合教材314-316內(nèi)容(2)被告未經(jīng)原告同意，擅自匯編790張圖片，侵犯了原告的復(fù)制權(quán)和演繹權(quán)中的匯編權(quán)。結(jié)合教材288頁內(nèi)容論述。（3）被告侵犯了原告的作品完整權(quán)，原告擅自使用790張圖片，編寫宋清瓷器圖錄一書，是對包含900張圖片的原告出版作品的篡改。結(jié)合教材281頁內(nèi)容（4）被告侵犯了原告取得報酬權(quán)。原告向社會出租圖片資料版權(quán)費(fèi)400遠(yuǎn)，加工制作費(fèi)400元，被告擅自使用圖片，造成原告經(jīng)濟(jì)損失 3、根據(jù)著作權(quán)法等法規(guī)的規(guī)定，被告應(yīng)當(dāng)立即公開賠禮道歉，賠償損失等民事責(zé)任。原告的作品系珍貴文物，因此被告應(yīng)按每張800遠(yuǎn)乘2予以賠償，應(yīng)賠償共計元。

13、 答辯參考要點(diǎn)：我接受某某律師事務(wù)所，作為被告出版社的辯護(hù)人，就故宮博物館訴出版社侵犯著作權(quán)一案，答辯如下： 1、出版人未侵犯故宮的著作權(quán)，不付賠償責(zé)任，原告的理由有漏洞。(請對以上原告代理意見從四個方面進(jìn)行反駁，闡述了個人理由，接合教材有關(guān)內(nèi)容根據(jù)自己理解論述)。 2、該書有作者，出版社只是出版了他人的作品，出版社沒有侵權(quán)圖書的著作權(quán)。作者非法使用原告圖片790張，是作者天津某教授具有侵犯原告著作權(quán)行為，應(yīng)為此承擔(dān)相應(yīng)的民事責(zé)任，不應(yīng)由出版社承擔(dān)。原告應(yīng)起訴作者的侵權(quán)行為 3、故宮博物館享有該作品的著作權(quán)，但原告故宮博物館提出的按每張800元乘2方式予以賠償，沒有法律依據(jù)，賠償額顯然跟我國法

14、律規(guī)定相違背。作為被告的辯護(hù)人認(rèn)為這種賠償方式是不應(yīng)該成立的。就賠償問題來說，這個價格不應(yīng)該這樣計算，相關(guān)法律法規(guī)并沒有規(guī)定翻兩倍的算法，對于賠償損失范圍，著作權(quán)法規(guī)定，以被害人的實際損失為限。 知識產(chǎn)權(quán)法形成性考核冊作業(yè)4一、名詞解釋：1、知識產(chǎn)權(quán)：是治理成果所有人和使用人給予自己所擁有的智力成果而依法享有的各項民事權(quán)利的總和，包括著作權(quán)、商標(biāo)權(quán)、專利權(quán)、閥線圈、發(fā)明權(quán)以及其他科技成果權(quán)。知識產(chǎn)權(quán)是一個隨著科學(xué)技術(shù)、文學(xué)藝術(shù)的發(fā)展而不斷拓展和深化的概念2、商標(biāo)權(quán):根據(jù)我國商標(biāo)法的有關(guān)規(guī)定，商標(biāo)權(quán)也可稱為商標(biāo)專用權(quán)是指商標(biāo)注冊人對其注冊商標(biāo)所享有的權(quán)利。3、專利權(quán)：是發(fā)明基于發(fā)明創(chuàng)造，通過申請

15、專利的方法，公開自己發(fā)明創(chuàng)造的技術(shù)內(nèi)容，經(jīng)審查程序而取得的專有有權(quán)，是發(fā)明人在一定期限內(nèi)對其發(fā)明享有的獨(dú)占權(quán)。4、著作權(quán)：也稱版權(quán)，指作者對其創(chuàng)作的文學(xué)藝術(shù)和科學(xué)作品依法享有的權(quán)利。5、侵犯商業(yè)秘密行為：是指行為人采取不當(dāng)手段獲取、披露、使用權(quán)利人的商業(yè)秘密或者違反合同約定擅自允許他人使 用別人的商業(yè)秘密的行為。二、填空：1、國家知識產(chǎn)權(quán)局 2、自愿注冊強(qiáng)制注冊 3、商標(biāo)國際注冊逐一國家注冊 4、個案認(rèn)定被動認(rèn)定 5、新穎性創(chuàng)造性實用性 6、形狀圖案色彩 7、責(zé)任視為作者 8、同意報酬同意報酬 9、一種直接 三、選擇 1、AB 2、B 3、BCD 4、ABD 5、ABC 6、AD 7、D 8、

It is synt

20、hesized within the nerve terminal from choline, taken up from the tissue fluid into the nerve ending by a specialized transport mechanism. The enzyme necessary for this synthesis is formed in the nerve cell body and passes down the axon to its end, carried in the axoplasmic flow, the slow movement o

When a nerve action potential reaches and invades the nerve terminal, a shower of acetylcholine vesicles is released into the junction (synapse) between the nerve ter

Thus electrical signals are converted to chemical signals, allowing messages to be passed between nerve cells or between nerve cells and non-nerve cells. This process is termed chemical n

Acetylcholine acts as a transmitter between motor nerves and the fibres of skeletal muscle at all neuromuscular jun

24、ctions. At this type of synapse, the nerve terminal is closely apposed to the cell membrane of a muscle fibre at the so-called motor end plate. On release, acetylcholine acts almost instantly, to cause a sequence of chemical and physical events (starting with depolarization of the motor endplate) wh

The action of acetylcholine is terminated rapidly, in around 10 milliseconds; an enzyme (cholinesterase) breaks the transmitter down into choline and

These same principles apply to cholinergic transmission at sites other than neuromuscular junctions, although the structure of the synapses differs. In the autonomic nervous system these include nerve-to-nerve synap

These terms are used because nicotine mimics the action of acetylcholine at nicotinic receptors, whereas muscarine, an alkaloid from the mushroom Amanita muscaria, mimics the action of acetylcholine at the muscarinic receptors. Acetylcholine is the

32、neurotransmitter produced by neurons referred to as cholinergic neurons. In the peripheral nervous system acetylcholine plays a role in skeletal muscle movement, as well as in the regulation of smooth muscle and cardiac muscle. In the central nervous system acetylcholine is believed to be involved i

33、n learning, memory, and mood. Acetylcholine is synthesized from choline and acetyl coenzyme A through the action of the enzyme choline acetyltransferase and becomes packaged into membrane-boundvesicles. After the arrival of a nerve signal at the termination of an axon, the vesicles fuse with the cel

34、l membrane, causing the release of acetylcholine into thesynaptic cleft. For the nerve signal to continue, acetylcholine must diffuse to another nearby neuron or muscle cell, where it will bind and activate areceptorprotein. There are two main types of cholinergic receptors, nicotinic and muscarinic

35、. Nicotinic receptors are located at synapses between two neurons and at synapses between neurons and skeletal muscle cells. Upon activation a nicotinic receptor acts as a channel for the movement of ions into and out of the neuron, directly resulting indepolarizationof the neuron. Muscarinic recept

36、ors, located at the synapses of nerves with smooth or cardiac muscle, trigger a chain of chemical events referred to as signal transduction. For a cholinergic neuron to receive another impulse, acetylcholine must be released from the receptor to which it has bound. This will only happen if the conce

37、ntration of acetylcholine in the synaptic cleft is very low. Low synaptic concentrations of acetylcholine can be maintained via a hydrolysis reaction catalyzed by the enzyme acetylcholinesterase. This enzyme hydrolyzes acetylcholine into acetic acid and choline. If acetylcholinesterase activity is i

38、nhibited, the synaptic concentration of acetylcholine will remain higher than normal. If this inhibition is irreversible, as in the case of exposure to many nerve gases and some pesticides, sweating, bronchial constriction, convulsions, paralysis, and possibly death can occur. Although irreversible

39、inhibition is dangerous, beneficial effects may be derived from transient (reversible) inhibition. Drugs that inhibit acetylcholinesterase in a reversible manner have been shown to improve memory in some people with Alzheimers disease. abstract expressionism, movement of abstract painting that emerg

40、ed in New York City during the mid-1940s and attained singular prominence in American art in the following decade; also called action painting and the New York school. It was the first important school in American painting to declare its independence from European styles and to influence the develop

41、ment of art abroad. Arshile Gorky first gave impetus to the movement. His paintings, derived at first from the art of Picasso, Mir, and surrealism, became more personally expressive. Jackson Pollocks turbulent yet elegant abstract paintings, which were created by spattering paint on huge canvases pl

42、aced on the floor, brought abstract expressionism before a hostile public. Willem de Koonings first one-man show in 1948 established him as a highly influential artist. His intensely complicated abstract paintings of the 1940s were followed by images of Woman, grotesque versions of buxom womanhood,

43、which were virtually unparalleled in the sustained savagery of their execution. Painters such as Philip Guston and Franz Kline turned to the abstract late in the 1940s and soon developed strikingly original stylesthe former, lyrical and evocative, the latter, forceful and boldly dramatic. Other impo

44、rtant artists involved with the movement included Hans Hofmann, Robert Motherwell, and Mark Rothko; among other major abstract expressionists were such painters as Clyfford Still, Theodoros Stamos, Adolph Gottlieb, Helen Frankenthaler, Lee Krasner, and Esteban Vicente. Abstract expressionism present

45、ed a broad range of stylistic diversity within its largely, though not exclusively, nonrepresentational framework. For example, the expressive violence and activity in paintings by de Kooning or Pollock marked the opposite end of the pole from the simple, quiescent images of Mark Rothko. Basic to mo

46、st abstract expressionist painting were the attention paid to surface qualities, i.e., qualities of brushstroke and texture; the use of huge canvases; the adoption of an approach to space in which all parts of the canvas played an equally vital role in the total work; the harnessing of accidents tha

47、t occurred during the process of painting; the glorification of the act of painting itself as a means of visual communication; and the attempt to transfer pure emotion directly onto the canvas. The movement had an inestimable influence on the many varieties of work that followed it, especially in th

48、e way its proponents used color and materials. Its essential energy transmitted an enduring excitement to the American art scene. Science and technology is quite a broad category, and it covers everything from studying the stars and the planets to studying molecules and viruses. Beginning with the G

49、reeks and Hipparchus, continuing through Ptolemy, Copernicus and Galileo, and today with our work on the International Space Station, man continues to learn more and more about the heavens. From here, we look inward to biochemistry and biology. To truly understand biochemistry, scientists study and

50、see the unseen bystudying the chemistry of biological processes. This science, along with biophysics, aims to bring a better understanding of how bodies work from how we turn food into energy to how nerve impulses transmit.analytic geometry, branch ofgeometryin which points are represented with resp

Its most common application is in the representation of equations involving two or three variables as curves in two or three dimensions or surfaces in three dimensions. F

In this way a geometric problem can be translated into an algebraic problem and the methods of al

Conversely, the solution of a problem in algebra, such as finding the roots of an equation or system of equations, can be estimated or sometimes given exactly by geometric means, e.g., plotting curves and surfaces and determining points of intersection. In plan

54、e analytic geometry a line is frequently described in terms of its slope, which expresses its inclination to the coordinate axes; technically, the slopemof a straight line is the (trigonometric) tangent of the angle it makes with thex-axis. If the line is parallel to thex-axis, its slope is zero. Tw

55、o or more lines with equal slopes are parallel to one another. In general, the slope of the line through the points (x1,y1) and (x2,y2) is given bym= (y2-y1) / (x2-x1). The conic sections are treated in analytic geometry as the curves corresponding to the general quadratic equationax2+bxy+cy2+dx+ey+

In solid analytic geometry the orientation of a straight line is given not by one slope but by its direction cosines, , , and , the cosines of the angles the line makes with thex-, y-,andz-axes, respectively; these satisfy the relationship

57、 2+2+2= 1. In the same way that the conic sections are studied in two dimensions, the 17 quadric surfaces, e.g., the ellipsoid, paraboloid, and elliptic paraboloid, are studied in solid analytic geometry in terms of the general equationax2+by2+cz2+dxy+exz+fyz+px+qy+rz+s=0. The methods of analytic ge

58、ometry have been generalized to four or more dimensions and have been combined with other branches of geometry. Analytic geometry was introduced by RenDescartesin 1637 and was of fundamental importance in the development of thecalculusby Sir Isaac Newton and G. W. Leibniz in the late 17th cent. More

59、 recently it has served as the basis for the modern development and exploitation ofalgebraic geometry. circle, closed plane curve consisting of all points at a given distance from some fixed point, called the center. A circle is a conic section cut by a plane perpendicular to the axis of the cone. T

60、he term circle is also used to refer to the region enclosed by the curve, more properly called a circular region. The radius of a circle is any line segment connecting the center and a point on the curve; the term is also used for the length r of this segment, i.e., the common distance of all points

61、 on the curve from the center. Similarly, the circumference of a circle is either the curve itself or its length of arc. A line segment whose two ends lie on the circumference is a chord; a chord through the center is the diameter. A secant is a line of indefinite length intersecting the circle at t

62、wo points, the segment of it within the circle being a chord. A tangent to a circle is a straight line touching the circle at only one point, the point of contact, or tangency, and is always perpendicular to the radius drawn to this point. A circle is inscribed in a polygon if each side of the polyg

63、on is tangent to the circle; a circle is circumscribed about a polygon if all the vertices of the polygon lie on the circumference. The length of the circumference C of a circle is equal to (see pi) times twice the radius distance r, or C=2r. The area A bounded by a circle is given by A=r2. Greek ge

64、ometry left many unsolved problems about circles, including the problem of squaring the circle, i.e., constructing a square with an area equal to that of a given circle, using only a straight edge and compass; it was finally proved impossible in the late 19th cent. (see geometric problems of antiqui

65、ty). In modern mathematics the circle is the basis for such theories as inversive geometry and certain non-Euclidean geometries. The circle figures significantly in many cultures. In religion and art it frequently symbolizes heaven, eternity, or the universe.整理范文，僅供參考?xì)g迎您下載我們的文檔資料可以編輯修改使用致力于合同簡歷、論文寫作、PPT設(shè)計、計劃書、策劃案、學(xué)習(xí)課件、各類模板等方方面面，打造全網(wǎng)一站式需求覺得好可以點(diǎn)個贊哦如果沒有找到合適的文檔資料，可以留言告知我們哦10
