Developing prospect of the new wave-absorbing materials (nanometer agents, conducting polymer and retinyl schiff base) is also discussed. 展望了纳米吸收剂、导电高分子、视黄基席夫碱等新型微波吸收剂的发展前景。

But in winter while the temperature was lower, they were mostly in deposited forms, so retinyl palmitat was at higher level than that in summer. 而冬季外界温度较低，肝脏内维生素主要以其储存形式存在，表现出软脂酸视黄酯含量高。
