三 . dynamic gain equalizer ( dge ) based on volume phase grating ( vpg ) . edfa ' s gain spectrum has dependence on the edfa ' s operate point Edfa在不同的工作状态具有不同的增益谱,这就要求增益补偿器件的增益谱形状要随edfa工作状态的不同而发生变化。
It is found that starch microgel has microporous network structure and environmental responsiveness , moreover , its volume phase transition temperature ( tc ) is around 37 , which are researched by the characterization of tem , dls , light refraction and other techniques . so , starch microgel with those advantages can be expected to use as a targeting drug carrier 借助透射电镜、动态光散射、光折射等技术的表征,发现所制备的淀粉微凝胶具有微孔网络结构和环境敏感性,而且相体积转变温度( t _ c )约37 ,所制淀粉微凝胶的这些优越性可望作为靶向药物载体。
