1·Then the possibility of larger phase velocity and group velocity than light speed in dispersive medium is discussed.

然后从色散介质中相速度与群速度的关系，讨论了相速度和群速度超光速的可能性。

2·This paper is devoted to the estimation of Q-factor in dispersive medium from zero offset VSP data in the wavelet domain.

讨论了地震子波为一般零相位子波情况下，利用零偏移距垂直地震剖面（VSP）资料在时-频域计算Q值方法。

3·The dispersion and absorption are a pair of fundamental properties of optical medium. The use of the dispersive properties is often limited by the absorption.

吸收和色散性质是光学介质的一对基本性质，吸收性质往往会限制色散性质的利用。

4·Manipulation of light speed in an optical medium can be realized by changing the dispersive properties of the medium.

通过改变介质的色散性质人们能控制光学介质中光的传播速度。

5·The cutoff characteristics of dielectric-filled circular holes embedded in a dispersive plasmonic medium are investigated.

研究了色散等离子体介质中用电介质填充的圆孔的截止特性。

6·The propagation velocity of elastic wave with different frequencies in same medium is various, which is called dispersive problem of frequency.

相同介质中不同频率的弹性波传播速度是有差异的，即频散问题。
