摘　　要：本文报告对国人3-10月龄胎儿尸体611例的1222侧肺的叶间裂和分叶的观察,结果表明:完全肺叶间裂占77.49％;不完全肺叶间裂占22.18％;无肺叶间裂占0.32％。按肺的叶间裂(完全叶间裂和不完全叶间裂)和肺叶的多少,可将肺分为8型:最少一叶,最多不完全五叶。左肺以二叶为主占90.67％,右肺以三叶和不完全三叶为主占87.39％。左肺三叶以上很少只占5.89％,四叶以上只见于右肺。一叶和不完全二叶左肺是右肺的7倍。This article reports the observations on interlobar fissures and lobulation in 1222lungs of 611 Chinese fetal corpses at the fetal age of 3 to 10 months by autopsy. The results show that the lungs with complete, incomplete, and no interlobar fissures make up 77.49, 22.18, and 0.32per cent respectively. According to the forms of interlobar fissures(complete and incomplete interlobar fissures)and the number of lung lobes, lungs could be divided into 8 types, among which, there are one lobe at least and five incomplete lobes at most. Most of the left lungs(90.67%)have two lobes, only a few (5.89%)have more than 3 lobes. There are no left lungs with lobes more than 4.Most of the fight lungs(87.39%)had 3 complete or incomplete lobes. Only the right lungs have lobes more than 4.The number of the left lungs with 1 lobe or 2 incomplete lobes are 7 times as many as that of the fight lungs.
