例句与造句
- in fact there is no real superluminal travel involved

二参量描述的超光速中微子述的超光速中微子 - superluminal paradox and neutrino
超光速佯谬和中微子 - at least, in weak interaction, neutrinos may be superluminal particles
至少在弱相互作用中，中微子可能是超光速粒子。 - apparent superluminal motion
视超光速运动 - It's difficult to find superluminal in a sentence. 用superluminal造句挺难的
- often there is confusion about the idea that wormholes allow superluminal ( faster-than-light ) space travel
常常存在有关虫孔能够超光速(比光速更快)空间旅行的混乱观念。 - photonic crystal, negative refractive index materials, superluminal and subluminal phenomena, partially coherent light, laser physics, and interaction between light and matter
光子晶体，负折射率材料，超快、超慢现象，部分相干光学，激光物理，光与物质的相互作用等。 - 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，在色散光谱的中心区域，呈现出无吸收负色散，这种效应能够导致超光速传播，但它随着修饰态间距增加而减弱。 - 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
本文中我们首先计算了在拓扑结构为s~1r~3的非minkowski时空中扭曲标量场和非扭曲标量场的真空极化，然后考虑了真空极化对光子传播的影响，我们发现除了光子的极化方向和传播方向都垂直于紧致化方向的情形之外，非扭曲标量场的真空极化使所有其他的光子模式都获得实的拓扑质量从而导致这些光子以亚光速传播；但是，扭曲标量场的真空极化使光子获得虚的拓扑质量以致他们以超光速传播。 - 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
对凹陷波导（undersizedwaveguide）的模拟发现：输入脉冲宽度较大的高斯波包，模拟结果显示输出波形失真较小，经过计算得到电磁波包穿过长50mm的截止区时，电场的幅度衰减了-41.5db，群速度为3.21c。
