   至少在弱相互作用中，中微子可能是超光速粒子。
5. apparent superluminal motion
   視超光速運動
6. It's difficult to find superluminal in a sentence. 用superluminal造句挺難的
7. often there is confusion about the idea that wormholes allow superluminal ( faster-than-light ) space travel

8. photonic crystal, negative refractive index materials, superluminal and subluminal phenomena, partially coherent light, laser physics, and interaction between light and matter
   光子晶體，負折射率材料，超快、超慢現(xiàn)象，部分相干光學，激光物理，光與物質的相互作用等。
9. second, negative dispersion without absorption, which leads to superluminal light propagation, is achievable in the central resonance structure of the dispersion spectrum . the negative dispersion is slightly weakened as the spacings between dressed states increase
   其次，在色散光譜的中心區(qū)域，呈現(xiàn)出無吸收負色散，這種效應能夠導致超光速傳播，但它隨著修飾態(tài)間距增加而減弱。
10. the one-loop vacuum polarization is calculated for untwisted and twisted scalar fields in a flat space-time with the topology s1 r3 . the effect of vacuum polarization upon photon propagation is considered . it is found that for the untwisted scalar field some photon modes acquire a positive topological mass, thus travelling at a subluminal speed; but for the twisted scalar field some photon modes get an imaginary topological mass and travel at a superluminal speed
    本文中我們首先計算了在拓撲結構為s~1r~3的非minkowski時空中扭曲標量場和非扭曲標量場的真空極化，然后考慮了真空極化對光子傳播的影響，我們發(fā)現(xiàn)除了光子的極化方向和傳播方向都垂直于緊致化方向的情形之外，非扭曲標量場的真空極化使所有其他的光子模式都獲得實的拓撲質量從而導致這些光子以亞光速傳播；但是，扭曲標量場的真空極化使光子獲得虛的拓撲質量以致他們以超光速傳播。
11. the followings were discovered in the simulations of undersized waveguide : when the pulse width of input signal, a gaussian packet, is rather wide, the output signal distorted little . a superluminal group velocity 3.21c was revealed when the wave packet crossing 50mm forbidden region
    對凹陷波導（undersizedwaveguide）的模擬發(fā)現(xiàn)：輸入脈沖寬度較大的高斯波包，模擬結果顯示輸出波形失真較小，經(jīng)過計算得到電磁波包穿過長50mm的截止區(qū)時，電場的幅度衰減了-41.5db，群速度為3.21c。
