摘　　要：Light and electron microscopic studies were carried out in order to characterize haemocytes in the bivalve mollusc Meretrix meretrix. According to nucleus and cytoplasm characters, four types of haemocytes were recognized： agranular haemocytes, lymphoid haemocyte, large granular and small granular haemocytes. Agranular hamocyte is the main cell type, accounting for 75%. It is agranular with rich organelles in cytoplasm, including mitochondria, golgi body and endoplasmic reticulum. Glycogen deposits were usually found in this cell type. The number of lymphoid haemocyte accounts for 1% - 2%. This cell type is agranular and shows a high ratio of nucleus to cytoplasm. A few organelles were found. High electrondense granules with diameters of 0.2 - 0.5μm and rich organelles were found in small granular haemocyte. The proportion of this cell type is about 15%. Rich granules of high electron-dense with diameters of 0.8- 2.4μm were found in large granular haemocyte. The proportion of this cell type is about 10%, and the quantity of organelles is the least.光和电子显微镜的研究被执行以便在瓣鳃类软体动物 Meretrix meretrix 描绘 haemocytes。根据原子核和细胞质人物， haemocytes 的四种类型被认出：小粒的 haemocytes，淋巴的 haemocyte，大小粒、小的小粒的 haemocytes。Agranular hamocyte 是主要房间类型，为 75% 的财务。它是一与在细胞质的富有的细胞器小粒包括线粒体， golgi 身体 andendoplasmic 蜂窝胃。肝糖存款通常在这种房间类型被发现。淋巴的 haemocyte 的数字说明 1%-2% 。这种房间类型是一小粒并且显示出原子核的高比率到细胞质。一些细胞器被发现。有直径 of0.2 的高电子稠密的小粒 - 0.5 μ m 和富有的细胞器在小小粒的 haemocyte 被发现。这种房间类型的比例是大约 15% 。与 0.8 的直径电子稠密的高度的富有的小粒 - 2.4 μ m 在大小粒的 haemocyte 被发现。这种房间类型的比例是大约 10% ，并且细胞器的数量是最少。
