摘　　要：An existence criterion of triple positive solutions to a third-order m-point boundary value problem{v″′(s)+λh(s)f(s,v(s),v′(s))=0,s∈(0,1),v(0)=v″(0)=0,v′(1)=∑m-i=1kiv(ηi),is established by Avery-Peterson fixed point theorem.At the same time,a corresponding example is given to illustrate the result.
