摘要
本文用偏振光显微镜对水溶DNA薄膜进行观察,发现在一定浓度以上的DNA溶液具有明显的各向异性,并呈现出几种典型的光学织构,其形式依条件而异。
The films of DNA + water system were observed by ues of a polarized microscope.It has been found the large birefringence existed in the films while the concentrationwas up to a certen one, and special textures appeared in different conditions.
