用慢正电子束多普勒展宽谱研究环氧丙烯酸酯（ＥＡ）体系电子束固化（ＥＢＣ）涂层。Ｓ－Ｅ曲线给出了稀释剂分子结构及其相对含量、辐射剂量、预聚物和交联剂含量等对ＥＢＣ涂层微观结构的影响，以及随深度变化的信息。
Epoxy acrylate (EA) system electron beam cured (EBC) coatings were studied by slow positron beam Doppler broadening spectrum. The S-E curve gives the influence of the molecular structure of the diluent, the relative content of the diluent, the radiation dose, the content of the prepolymer and the crosslinking agent on the microstructure of the EBC coating, and the information on the variation with depth.
