The nuclear pore complex in spermatogenesis of Beijing domestic duck has been studied by means of electron microscopic observation of freeze-etching. The structure of the pore observed proves to be in accord with the model of the nuclear pore complex proposed respectively by Franke (1970) and Roberts et al. (1970). But its central granule may be present (1-3 granules) or absent. The granules are considered to be material in transit. The size and frequency of the pore vary with different types of reproductive cells, which is believed to be related to the cells' function. The pores concentrate on the side of nucleus near Golgi zone in primary spermatocyte and near the proacrosome of spermatid, and this shows the functional variety of parts in the nucleus.
通过冷冻蚀刻电子显微镜观察，对北京家鸭精子发生过程中的核孔复合体进行了研究。观察到的核孔结构与Franke（1970年）和Roberts等人（1970年）分别提出的核孔复合体模型相符。但其中央颗粒可能存在（1 - 3个颗粒），也可能不存在。这些颗粒被认为是转运中的物质。核孔的大小和频率随生殖细胞类型的不同而变化，这被认为与细胞功能有关。核孔集中在初级精母细胞核靠近高尔基体区域的一侧以及精子细胞核前顶体附近，这显示了细胞核各部分功能的多样性。
