摘　　要：用2-硝基-5-(N-甲基-N-十八烷基)氨基苯甲酸(NMOB)和花生酸制备了200层的交替多层膜,测得其二次谐波信号强度与NMOB层数的平方成正比.论文着重讨论了NMOB的Y型膜和它与花生酸的交替膜中的取向,并对两者之间的不同作了初步的解释.Two hundred layers of assembled LB films by using 2 - nitro - 5 - (N - methyl - N -octadecylamino) benzoic acid (NMOB) and arachidic acid were prepared. Its Second Harmonic intensity was quadratically increasing with the number of NMOB layers. The different orientations of NMOB in this assembled LB films and in its Y- type films were also discussed in this paper.
