中文摘要：

本文以POSS/环氧树脂的二元体系为主体,研究了电子束辐照对该二元体系在透射电镜观察中的作用。研究表明,随着电子束辐照强度和辐照时间的增加,二元体系中POSS分散相的衬度越来越明显,得到的TEM图像也更加清晰。本文采用TEM图像的相对灰度值定量研究了电子束辐照时间对图像清晰度的影响,探索了电子束辐照对该二元体系TEM像衬度提高的原理。

英文摘要：

In this paper, the role of electron irradiation in TEM observation was investigated using POSS/epoxy resin as an example. The results show that the contract of POSS in this binary system increases with the electron irradiation intensity and the irradiation time. Using the electron irradiation, clearer TEM photo can be obtained. The relative grey value is employed for quantitative analysis. The mechanism of electron-beam irradiation is also presumed.
