单分子膜研究的方法及现状

单分子膜一般是将两亲性物质溶解在铺展溶剂中制成铺展溶液，然后铺展在底液上而得的。在其性质的研究中，测定表面压－面积关系曲线是最基本、也是最重要的一种研究手段。但是，仅有表面压－面积曲线所能了解的信息是远远不够的，因此必须结合另一些手段进行研究，测定表面粘度就是其中很重要的一种。而随着现代光谱仪器的更新、发展，光学方法已日益成为单分子膜研究的一个重要途径。

Ways and Current Situation of Monolayer Studies

Monolayers are generally formed at air/weater interface by spreading proper solutions in which amphiprotic substances are ressolved.A large number of studies have been carried out in order to understand the peoperties and structures of the monolayers.Of the researching methods,the pressure-area curve is the most foundamental and important.The other techniques involve measurement of surface viscosity and optical properties of monolayers.With advancing and developing of spectrometers,sensitive imaging techniques have been opening up new prospect for a better understanding of the physics of the monolayers.
