橢圓的焦點(diǎn)公式怎樣的？

橢圓焦點(diǎn)坐標(biāo)公式：x/a+y/b=1。

1、橢圓的焦點(diǎn)三角形簡稱焦三角形，是指以橢圓的兩個(gè)焦點(diǎn)。在我們的直角坐標(biāo)系中，引入極坐標(biāo)系：讓極坐標(biāo)的極點(diǎn)與直角坐標(biāo)的原點(diǎn)重合，讓極坐標(biāo)的極軸與x的正半軸重合，而且讓極坐標(biāo)系的單位長度與直角坐標(biāo)系的單位長度重合。

2、F1,F2與橢圓上任意一點(diǎn)P為定點(diǎn)組成的三角形。先做兩次兩條平行弦，在各作中點(diǎn)連線，可以確定原點(diǎn)。然后以原點(diǎn)做圓，交橢圓有四個(gè)交點(diǎn)，可以以橢圓的對稱性確定x，y軸。然后根據(jù)c方=a方-b方，短軸端點(diǎn)到兩交點(diǎn)距離和為2a，用圓規(guī)拉一個(gè)直角三角形出來，就可以了。具體操作就是以短軸端點(diǎn)為圓心，長半軸長為半徑做圓，交長軸就是焦點(diǎn)。

3、橢圓坐標(biāo)系英語Elliptic coordinate system，是一種二維正交坐標(biāo)系。橢圓周長理論公式是存在的不過它不能用初等函數(shù)表示，它是一個(gè)與離心率有關(guān)的無窮收斂級數(shù)，本公式已經(jīng)把正圓周長納入其中，在某種意義上講正圓是特殊的橢圓，也就是說正圓是長短軸相等的橢圓。

最優(yōu)效率的轉(zhuǎn)移軌道應(yīng)開始于初始軌道？

在兩條不同軌道之間的過渡軌道并不是唯一的，過渡軌道最佳化理論就是要尋找在某種條件下消耗能量最省的過渡軌道。

在航天工程中，過渡軌道的選擇要綜合考慮能量消耗、飛行時(shí)間、制導(dǎo)精度、測量和控制條件等因素。轉(zhuǎn)移軌道又稱過渡軌道，是航天器從初始軌道或停泊軌道過渡到工作軌道的中間軌道。從轉(zhuǎn)移速度和能源效率方面可分為霍曼轉(zhuǎn)移軌道(Hohmann transfer orbit)、雙橢圓轉(zhuǎn)移軌道(Bi-elliptic transfer orbit)和地球同步轉(zhuǎn)移軌道(Geostationary transfer orbit,GTO)。
