对１００例成人尸肺（左右共２００侧）进行直接观测，结果右肺不全水平裂６５例（占６５％），右肺中、上叶部分融合型的不典型三叶分型占多数，与一般资料相近。左肺完全性水平裂１１例（占１１％），不全性水平裂４９例（占４９％）；二者共计６０例（占６０％）。左肺外形分叶中，完全和不完全水平裂的存在及左肺的不典型三叶分型，在临床影像学检查中具有重要意义；在教学中，使学生认识肺的内部分叶与外形分叶的不一致性亦有一定意义
Direct observation of 100 adult cadaveric lungs (left and right total of 200 sides) revealed 65 cases (65%) of right lung incompetent horizontal cleavage and a majority of atypical trilobes in the middle and upper lobes of the right lung, General information is similar. Left lung complete horizontal cleft in 11 cases (11%), 49 cases of incomplete horizontal cleft (49%); both a total of 60 cases (60%). In left lobe shape lobes, the presence of complete and incomplete horizontal cleft and the atypical cloverleaf of left lung are of great significance in clinical imaging studies. In teaching, students are allowed to know the inner lobe and appearance of lung Leaf inconsistency also has some significance
