This paper is the continued study on age structure of scientific collaboration in Chinese computer science. Based on an extended
database a new method is used to analyze the nature and preference of collaboration. Observed values of two- three- and four-dimensional
collaboration were compared respectively with their expected values. Investigation covered co-authors" combination patterns,
name permutations in their papers, especially the age of the first author.

This paper is a scientometric study of the age structure of scientific collaboration in Chinese computer science. Analysis
reveals some special age structures in scientific collaboration in Chinese computer science. Most collaborations are composed
of scientists younger than thirty-six (Younger) or older than fifty (Elder). For two-dimensional collaboration formed by first
and second authors, Younger-Elder and Younger-Younger are the predominant age structures. For three-dimensional collaboration
formed by first, second and third authors, Younger-Younger-Elder and Younger-Younger-Younger are the most important age structures.
Collaboration between two authors older than 38 amounts to only 6.4 percent of all two-person collaborations. Collaboration
between two middle-aged scientists is seldom seen.
Why do such types of age structure in Chinese computer science exist? We suggest a tentative explanation based on analyses
of the age composition of all authors, the age distributions of the authors in different ranks, and the name-ordering of authors
in articles written by professors and their students.
