研究了华北地台晚古生代沉积中腕足动物化石（共鉴定出６６属２３０余种）；分析了区域内不同时期腕足动物群的面貌特征，认为腕足动物的演化与发展具有明显的阶段性和全区的统一性；首次建立了华北地台范围内八个腕足动物组合．这是迄今为止华北地台腕足动物研究中最系统最丰富的资料．
In the Late Paleozoic sediments of North China Platform, the brachiopod fossils (more than 230 species were identified in 66 genera) were analyzed. The facial features of brachiopods at different stages in the region were analyzed. The evolution and development of brachiopod animals showed obvious stage and complete Regional unity; for the first time established within the scope of North China eight brachiopods.
