橢圓的長(cháng)軸和短軸分別指哪個(gè)?圖像是什么？

橢圓的長(cháng)軸和短軸分別是哪個(gè)，請看以下圖片：

簡(jiǎn)介：橢圓截與兩焦點(diǎn)連線(xiàn)重合的直線(xiàn)所得的弦為長(cháng)軸；橢圓截垂直平分兩焦點(diǎn)連線(xiàn)的直線(xiàn)所得弦為短軸。橢圓是平面內到定點(diǎn)F1、F2的距離之和等于常數（大于|F1F2|）的動(dòng)點(diǎn)P的軌跡，F1、F2稱(chēng)為橢圓的兩個(gè)焦點(diǎn)。其數學(xué)表達式為：|PF1|+|PF2|=2a（2a>|F1F2|）。研究歷史：阿波羅尼奧斯所著(zhù)的八冊《圓錐曲線(xiàn)論（Conics）》中首次提出了今日大家熟知的 ellipse（橢圓）、parabola（拋物線(xiàn)）、hyperbola（雙曲線(xiàn)）等與圓錐截線(xiàn)有關(guān)的名詞，可以說(shuō)是古希臘幾何學(xué)的精擘之作。 直到十六、十七世紀之交，開(kāi)普勒（Kepler）行星運行三定律的發(fā)現才知道行星繞太陽(yáng)運行的軌道，是一種以太陽(yáng)為其一焦點(diǎn)的橢圓。光學(xué)性質(zhì)：橢圓的面鏡（以橢圓的長(cháng)軸為軸，把橢圓轉動(dòng)180度形成的立體圖形，其內表面全部做成反射面，中空）可以將某個(gè)焦點(diǎn)發(fā)出的光線(xiàn)全部反射到另一個(gè)焦點(diǎn)處；橢圓的透鏡有匯聚光線(xiàn)的作用（也叫凸透鏡），老花眼鏡、放大鏡和遠視眼鏡都是這種鏡片。

以上就是橢圓的長(cháng)軸和短軸區別以及圖像，希望對您有所幫助。
