摘　　要：证明了在有外加电场的双光子光折变介质中存在非相干耦合屏蔽空间灰孤子族。这种孤子族是由多束偏振方向和波长都相同的互不相干光束耦合形成的。数值结果表明:当孤子只有两个分量时,屏蔽灰孤子族可以退化成屏蔽灰-灰孤子对;当孤子的灰度参量取零时,屏蔽灰孤子族退化成暗孤子族,而屏蔽灰-灰孤子对则退化成暗-暗孤子对。Grey screening solitons families do exist in biased two-photon photorefractive crystals is predicted.The grey soliton families can be established by incident beams which are mutually incoherent while have the same polarization and wavelength.The result shows that the grey screening soliton families would reduce to grey-grey soliton pairs when they contain only two components,and soliton families or soliton pairs will reduce to dark soliton families or dark-dark soliton pairs when the grayness of solitons takes zero.
