closed-orbits

基本解釋

Some sufficient condition to guarantee the existence of global invariant manifolds consisting zero homotopic closed orbits is gived.
同時(shí)給出了這類(lèi)系統(tǒng)存在由第一類(lèi)（零倫）閉軌組成的全局不變流形的條件。
Perhaps, the most famous one is the Comet Halley, it has a closed orbit with a period of 76 years.
最出名的封閉式軌道彗星當(dāng)然是以76年的周期繞日運(yùn)行的哈雷彗星。
By using the closed orbit theory, the photodetachment cross section of H- near a metal surface is derived and calculated.
利用閉合軌道理論，我們推導(dǎo)和計(jì)算了H-在金屬面附近的光剝離截面。
Unlike the case of the photodetachment of H- near an elastic interface, the length of the closed orbit does not equal the twice distance between the ion and the surface.
傅立葉變換截面中的每一條共振峰正好和電子的一條閉合軌道相對(duì)應(yīng)。
The period, action, and length of the detached electron’s closed orbit are nearly the same as the case of the photodetachment of H- near an elastic interface.
因此可以用彈性截面模擬金屬面。
