摘　　要：对双光子光折变晶体串联回路中明-暗屏蔽孤子对的暗孤子晶体温度对明孤子自偏转特性影响进行了理论研究。数值结果表明:明孤子的空间漂移随暗孤子的晶体温度变化而发生改变,暗孤子晶体温度的变化对明孤子的自偏转产生强烈的影响。用微扰法对自偏转的温度特性研究结果和通过数值法得到的结果符合的很好。这些结果对温控光器件的工程实现具有重要的参考价值。We investigate theoretically the dark soliton crystal temperature effect on the deflection of the bright one in a bright-dark screening soliton pair which is formed in a seral two-photon photorefractive crystal circuit .Our numerical result show that the spatial shift of the bright soliton changes with the temperature of the one crystal and varying the tenperature of dark soliton crystal can influence the defection strongly.The temperature dependence of the deflection process is ：Furthe studied by perturbation technique and the results are found to be good agreement with that obtained by numerical method. All title results have great value to the engineering realization of the optical-control optical and thermocontrol optical devices.
