摘要：In this paper, we present some partially balanced fractional 2 m 1+ m 2 factorial designs of resolution IV derived from partially balanced arrays of full strength such that (A) all the main effects and all the two-factor interactions within the m 1 factors and the m 2 ones each are estimable, (B) all the main effects and all the two-factor interactions within the m 1 ones and between the m 1 and m 2 ones are estimable, (C) all the main effects and all the two-factor interactions within the m 1 ones are estimable, (D) all the main effects and all the two-factor interactions between the m 1 and m 2 ones are estimable, and (E) all the main effects are estimable.
