根据Ｄｅｌｍｈｏｌｔｚ－Ｓｍｏｌｕｃｈｏｗｓｋｉ方程，由实验测定的流动电位来计算ＭＦ膜的ζ电位；并根据Ｇｏｕｙ－Ｃｈａｐｍａｎｎ方程，原估算出膜的微孔表面电荷密度。表明膜微孔表面ζ电位和电行密度与电解质的种类、浓度有关．ＮａＣｌ、ＫＣｌ和Ｎａ２ＳＯ４体系的ζ电位相近，ＭｇＣｌ２与ＭｇＳＯ４体系的ζ电位相近，即阳离子价态和结构越相近，ζ电位越相近，但当阴离子价态较高时，也有一定影响，由膜微孔表面ζ电位和电荷密度与溶液浓度的变化关系可知．在低浓度区域，膜表面ζ电位和电行密度较高，并出现１个峰值，之后随浓度增大而缓慢降低。

提出并分析了一种大范围可调谐的通带可变微波光子滤波器。它基于受激布里渊散射(SBS)效应并使用2个调制器与1个光纤布喇格光栅生成泵浦信号。通过分别调节这2个调制器的调制频率,可得双通带滤波器和通带间隔可变的四通带滤波器,并实现滤波器中心频率的大范围连续可调谐,而在整个调谐过程中,滤波器的3dB带宽保持不变。仿真分析了不同调制信号对滤波器通带及中心频率的影响,以及滤波器的带宽与泵浦的功率和SBS增益介质长度的关系。
