摘　　要：研究了沉积在液体基底 (硅油 )表面金薄膜中的带状有序结构和自组装现象 .实验结果表明 :在一定条件下 ,生长在硅油表面的金薄膜中可形成一种特征的有序结构 ,它是由近似矩形状的畴块拼接而成的 ;相邻畴块的长度近似相等 ,但宽度一般不同 ,因而具有特征长度为 10 1 — 10 2 μm数量级的准周期结构 .进一步的实验发现 :此类带状有序结构是由薄膜中特征内应力所引起的物质相互挤压而形成的 .另外 。An optical microscopy study of ordered structures and self-organized phenomena in a continuous gold film system deposited on silicone oil surface is presented. Band-shaped ordered patterns, namely bands, are formed after deposition under certain condition. The bands are composed of a large number of parallel key-shaped domains with different width but nearly uniform length. Further experiments show that the ordered patterns result from compressive stress in films. We also study the formation mechanism of internal stress in nearly free sustained films.
