英文摘要：

M. K. Azarian gave a generalization of a lemma by C. Y. Tang, and its exact analog for the lower near Frattini subgroups. Also, he proposed two open questions. To answer these questions this paper makes further investigation on some Frattini-like subgroups of amalgamated free products of groups and obtains several results.
