Insoluble monolayrs on the water surface are the most fundamental existence of the amphiphatic materials, such as surfactants and long-chain acids or alcohols. It was difficult to study the structure of monolayrs in molecular order because of the ultrathin character of the films and/or trace amount of materials. We have constructed a Brewster Angle Microscope(BAM) which was developed at France in 1991. Our BAM can observe structure in monolayrs directly at the resolution of 10mum. We did in situ observation of the structural change of monolayrs with phase transitions, with changing temperature and pressure, and by addition of divalent metal ions using BAM.We have also studied photopolymerization of long-chain derivatives of diacetylene by using the instantaneous multichannel photospectroscopy. We have developed a temperature-programmable Langmuir trough of very high performance using a large amount of Peltier elements. With this instrument, we have found a curious phase transition of a monolayr accompanying area contraction with increasing temperature.

表面活性剂、长链酸或醇等两亲物质在水表面最基本的存在是不溶性单分子膜。由于膜的非线性和/或微量物质的存在，很难按分子顺序研究单层膜的结构。我们已经建立了一个布鲁斯特角显微镜（BAM），这是在法国于1991年开发的。我们的BAM可以直接观察单层结构，分辨率为10 μ m。我们用BAM原位观察了具有相变的单分子膜结构随温度和压力的变化以及二价金属离子的加入的变化。我们还用瞬时多道光谱研究了长链二乙炔衍生物的光聚合。我们已经开发出一个温度可编程的朗缪尔槽的非常高的性能，使用大量的珀耳帖元件。用这种仪器，我们发现了一个奇怪的相变的单层伴随着面积收缩与温度的增加。
