利用F. Narin，收集了遗传学和分子生物学领域的科学期刊。在每一个领域中，都明确指出了主要标题，并通过这种方法确定了子领域。两步模型是一个很有价值的评价期刊馆藏的工具。
By using the two-step model which was developped by F. Narin, the collection of scientific journals in the genetics and molecular biology fields was analyzed. In each field, the major titles were clearly indicated and subfields were identified by this method. It seems that the two-step model is a valuable tool for evaluating journal collection.
