中国旅美科学家王力军与他的两位同事最近利用铯原子气体的反常色散现象，成功地在实验中将激光脉冲群速度达到真空光速的３１０倍之多。这一现象表明光波群能以“超光速”传播。 王力军等人的成果在日前出版的英国《自然》杂志上发表后，引起世界科学界的关注，很多国家的媒体
Chinese Lismo scientist Wang Lijun and two of his colleagues recently used the abnormal dispersion of cesium atom gas to successfully pilot the laser burst to 310 times the speed of light. This phenomenon shows that light wave group can “superluminal” spread. The achievements of Wang Lijun and others have aroused the attention of the scientific community in the world after the publication of the recently published British “Nature” magazine.
