- 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然是以76年的周期繞日運行的哈雷彗星。
- 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，我們推導和計算了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應。
- 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。
- Alternatively, if the star were small, the life-supporting planet would have to have a close orbit round it and also provide the perfect conditions for life forms to develop. 反之,如果恒星很小,維持生命的行星就要在離恒星很近的軌道上運行,而且要有極好的條件才能使生命得以發(fā)展
- Abstract： The distortion of closed orbit usually causes much side effect which is harmful to synchrotron radiation source such as HLS, so it is necessary to correct the distortion of closed orbit. 摘 要： 閉軌畸變對合肥同步光源的束流質(zhì)量產(chǎn)生負面影響，因此必須對閉軌畸變進(jìn)行校正。
- In the second chapter, we consider a kind of Kolmogorov system.The sufficient conditions of nonexistence of the closed orbit and existence of the unique and stable limit cycle are obtained. 第二章討論了一類(lèi)Kolmogorov系統，得到了系統無(wú)閉軌的充分條件和存在唯一穩定極限環(huán)的條件，推廣了顏向平，張存華等的結果。
- 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)系統存在由第一類(lèi)（零倫）閉軌組成的全局不變流形的條件。
- Maslov-type Indices for Iterations of Hyperbolic Closed Characteristics on Positive-type Hypersurfaces 正定型超曲面上雙曲閉特征的Maslov型指標的迭代公式
- Bifurcation of Closed Orbit for a Class of Cr System 一類(lèi)Cr系統的閉軌分支

- Have you closed the gate and windows? 你把門(mén)窗關(guān)嚴實(shí)了嗎？
- He closed his speech with a funny joke. 他用一則有趣的笑話(huà)結束了演講。
- That oyster closed up its valves. 那個(gè)牡蠣把殼合攏起來(lái)。
- Calculates the inverse hyperbolic tangent of two. 結構的反雙曲正切值。
- She is buying a flat close to her office. 她正在購買(mǎi)一套靠近她辦公室的單元房。
- Returns the hyperbolic sine of the specified angle. 返回指定角度的雙曲正弦值。
- She's always been very close about her past life. 她對自己過(guò)去的生活一直守口如瓶。
