摘要
摸索了ＤＮＡ分子的水展膜电镜制样方法与技术，在无旋转投影设备的条件下，直接用透射电镜观察到了ＤＮＡ分子的线型结构。
The methed and the technique using electron microscope to sample DNA molecule with water unfolding film was discussed.In spite of no spinning projection,the thready structure of DNA molecule was observed directly with transmissive electric micro-scope.
