摘　　要：免出血症病毒无锡株A_2R—3的完整病毒颗粒呈球形,廿面体等轴对称、无囊膜、其直径约为33—37nm。空心病毒粒子亦可看到,其核心直径为21—25nm。病毒衣壳包裹在颗粒的最外层,由紧密连结的子粒所组成,子粒排列规则,呈管状结构。其长度约为5—6nm,中心孔径为2—3nm。廿面体对称的等边三角形的面由6个子粒所构成,即每条边上排列3个子粒。据此推算出病毒衣壳的子粒总数为42,分负数为4,三角形面数为80,结构单位数为240。In this paper some properties of the original strain of the RHDV-A_3R-3 (separated from Wu Xi, China 1984) was reported. The purified virions was stained with 2% PTA and examined by electromicroscopic observation. The results revealed that the virus particles have nonenveloped capsidand exhibited icosahedral symmetry. The full viral particles have 33—37nm in diameter. The capsomer is seen to be tubelike structures with 5—6nm in length and 2—3nm in diameter of central holes. The face of the trianglation of the icosahedron consisted of 6 capsomers and each edge has 3 capsomers, the primary face has 4 triangles(T=4), the number of capsomers are 42, the expanded faces are 80 and the total numbers of the structural units in a complete virus particle are 240.
