【摘要】 本工作以界面铺张－－硝酸银染色技术，对小鼠精母细胞联会复合体（ＳｙｎａｐｔｏｎｅｍａｌＣｏｍｐｌｅｘ，ＳＣ）进行了电镜下的观察和研究，根据ＳＣ的平均相对长度和臂比指数绘制了小鼠标准ＳＣ组型模式图，经与光镜下体细胞染色体比较表明：ＳＣ的平均相对长度和臂比指数同体细胞相应有丝分裂染色体（ＭｉｔｏｔｉｃＣｈｒｏｍｏｓｏｍｅ，ＭＣ）的数值有很好的一致性，该项工作为进一步研究ＳＣ畸变提供了可靠依据。更多还原

【Abstract】 The wopk employed surface spread and AgNO₃ staining to researchsynaptoncmal complex（SC）in mouse spermtocytes under an electronic mieroscope. It was showedthat the average relative length or arm ratio index between meiotie SC and mitosis chromosomes areidentically well by comparing with the mitosis chromosome observed under ligbt microscope. Ac-cording to the average relative length and arm ratio index ofSC. The standard idiogram ofmouse SCwas drawn up. It must be useful for further mutagenetic rescarch.更多还原
