 摘要  Packing constant is an important and interesting geometric parameter.Packingconstant A_x of Banach space is a real number such that if r≤A_x,then a infinitenumber of spheres of radius r can be packed in the unit ball U(X),and if r>A_x,only a finite number of spheres can be done.It began in the 1950 studyingpacking constant of special sequence spaces.Rankin found A_2 and A_p of space l_2and l_p(p>1)respectively in 1955 and in 1958.In 1976,Cleaver discussed Orliczsequence space equipped with Orlicz norm [l_M, ||·||_M]·under a strong condition,
