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 π (see pi) times twice the radius distance r, or C=2πr. The area A bounded by a circle is given by A=πr2. Greek geometry left many unsolved problems about circles, including the problem of squaring the circle, ., constructing a square with an area equal to that of a given circle, using only a straight edge and pass。 these satisfy the relationship λ2+μ2+ν2= 1. In the same way that the conic sections are studied in two dimensions, the 17 quadric surfaces, ., 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 geometry have been generalized to four or more dimensions and have been bined with other branches of geometry. Analytic geometry was introduced by Ren233。 the harnessing of accidents that occurred during the process of painting。s first oneman show in 1948 established him as a highly influential artist. His intensely plicated abstract paintings of the 1940s were followed by images of Woman, grotesque versions of buxom womanhood, 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 styles—the former, lyrical and evocative, the latter, forceful and boldly dramatic. Other important artists involved with the movement included Hans Hofmann, Robert Motherwell, and Mark Rothko。s disease. abstract expressionism, movement of abstract painting that emerged in New York City during the mid1940s and attained singular prominence in American art in the following decade。 an enzyme (cholinesterase) breaks the transmitter down into choline and an acetate ion. The choline is then available for reuptake into the nerve terminal. 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 nervetonerve synapses at the relay stations (ganglia) in both the sympathetic and the parasympathetic divisions, and the endings of parasympathetic nerve fibres on nonvoluntary (smooth) muscle, the heart, and glandular cells。 我國旅游產(chǎn)品的開發(fā)和質(zhì)量問題: ( 1)我國入境旅游市場經(jīng)營一直以接待團體觀光旅游為主,并且旅游線路和內(nèi)容相對較為單一,極大影響了再訪人次的提高。同時又由于距離遠(yuǎn),最容易遭受經(jīng)濟危機和世界油價上漲的打擊。 游客帶來的破壞: ( 1)接待游客數(shù)量過多、密度過大,超過景區(qū)的合理承載量,造成空氣中二氧化碳含量過高,從而對古建筑、文物等造成的破壞 ( 2)游客違規(guī)攀登、刻畫等,加速石刻、雕塑、壁畫的損壞 ( 3)游客踩踏帶來的破壞 ( 4)游客素質(zhì)偏低,直接破壞旅游 資源。 論述題 一、 旅游資源遭破壞的原因? 答: (一)旅游資源的自然破壞: 旅游資源是大自然的一部分,大自然的發(fā)展、變化都會影響它的變化,如地震、火山噴發(fā)、海嘯,都會直接改變一個地區(qū)的面貌,毀掉部分甚至一切旅游資源,這是突發(fā)性的。 簡答題 一 、 度假旅游的特點如下? 答:是人們利用假期(特別是帶薪假)休息、療養(yǎng)而進 行的旅游活動。 1旅游產(chǎn)品: 從需求角度看,總體旅游產(chǎn)品就是旅游者離家外出開始直至完成全程旅游活動并返回家中為止這一期間的全部旅行經(jīng)歷的總和。 2 旅游交通的特性: ( 1)服務(wù)對象的特殊性( 2)游覽性( 3)舒適性( 4)季節(jié)性 ( 5)層次性( 6)區(qū)域性 2 影響旅游交通方式選擇的因素: ( 1) 旅行目的( 2)運輸價格( 3)旅行距離( 4)旅行偏好和經(jīng)驗 2 旅游產(chǎn)品的特點: ( 1)產(chǎn)品的綜合性( 2)產(chǎn)品的無形性( 3)產(chǎn)品的不可轉(zhuǎn)移性 ( 4)產(chǎn)品的生產(chǎn)與消費同步性( 5) 產(chǎn)品的不可儲存性 2 旅游產(chǎn)品的生命周期: ( 1)投入期( 2)成長期( 3)成熟期( 4)衰退期 2 旅游市場的細(xì)分標(biāo)準(zhǔn): 以地理因素為標(biāo)準(zhǔn)進行劃分 以人口統(tǒng)計為劃分標(biāo)準(zhǔn) 根據(jù)旅游心理行為因素為劃分標(biāo)準(zhǔn) 世界六大旅游市場: ( 1)歐洲市場( 2)美洲市場( 3)東亞及太平洋地區(qū)市場 ( 4)非洲市場( 5)中東市場( 6)南亞市場 3 2021年, 韓國超過日本成為中國第一大客源國。 2 飯店計價方式: (選擇,熟悉前四個) ( 1)歐式計價飯店:指飯店客房價格僅包括房租,不含飲料、食品等其他費用。麥金托什提出旅游動機可劃分為四種基本類型: ( 1)身體方面的動機( 2)文化方面的動機( 3)人際(社會交往)方面的動機 ( 4)地位和聲望方面的動機 1 旅游資源的特點: ( 1)觀賞性( 2)客觀性( 3) 多樣性( 4)定向性( 5)易損性 ( 6)可創(chuàng)新性 1 根據(jù)旅游資源基本屬性劃分: ( 1)自然旅游資源( 2)人文旅游資源( 3)社會旅游資源 1 根據(jù)旅游資源的利用狀況劃分: ( 1)現(xiàn)實旅游資源( 2)潛在旅游資源 1 三大支柱: ( 1)旅行社業(yè)、( 2)交通運輸業(yè)( 3)旅館為代表的食宿業(yè)。 初創(chuàng)期中國旅游業(yè)發(fā)展三件重要的事情: ( 1)華僑服務(wù)社的建立 ( 2)中國國際旅行社的建立 ( 3)中國旅行游覽事業(yè)管理局的建立 1982 年 8 月 ,中國旅行游覽事業(yè)總局正式更名為中華人民共和國旅游局,作為國務(wù)院主管旅游事業(yè)的直屬機構(gòu)。電大 旅游學(xué)概論 期末 復(fù)習(xí)資料 考試小抄 一、 填空和單項選擇 遷徙特點: 被迫性、被動性、生存性 世界旅游組織關(guān)于旅游的概念: 旅游是指人們離開平時
