摘　　要：建立了含分压电阻的非相干耦合光折变屏蔽光伏空间孤子对理论.当分压电阻、晶体外加电场和晶体的光伏场取不同值时,可分别得到有无分压电阻的非相干耦合屏蔽孤子对、开路的非相干耦合光伏孤子对、有无分压电阻的闭路的非相干耦合光伏孤子对和有无分压电阻的非相干耦合屏蔽光伏孤子对.先前已报道的非相干耦合孤子对理论都可在不同的条件下从本文理论得出.Steady-state incoherently coupled screening photovoltaic spatial soliton pairs are predicted for biased photorefractive crystal circuit with a divider resistance.All kinds of the incoherently coupled spatial soliton pairs can be obtained from this theory by adjusting the values of the divider resistance,the biased electric field and photovoltaic electric field,such as the incoherently coupled screening spatial soliton pairs in biased photorefractive crystal with or without a divider resistance,the photovoltaic spatial soliton pairs in open-circuit,the photovoltaic spatial soliton pairs in close-circuit with or without a divider resistance,the screening-photovoltaic spatial soliton pairs in biased photovoltaic-photorefractive crystal with or without a divider resistance.Previous theories advanced individually elsewhere for these soliton pairs can be obtained by simplifying this theory under appropriate conditions.
