Let K={k"1,k"2,...,k"r} and L={l"1,l"2,...,l"s} be sets of nonnegative integers with k"is-r. Let F={F"1,F"2,...,F"m} be a family of subsets of [n] with |F"i|@?K for each i and |F"i@?F"j|@?L for any ij. We prove that |F|@?@?"i"="s"-"r^sn-1i when we have the conditions that |F"i|@?L and k"i's are consecutive. We also prove the same bound under the condition @?"i"="1^mF"i0@? instead of the above conditions. Finally, an observation gives us a bound of n@?n2@? on |F| when K@?L=0@?.
