摘要：
In this paper, we present some sufficient conditions for which a Banach space X has normal structure in term of the modulus of weak uniform rotundity delta(X)(epsilon, f), the Dominguez-Benavides coefficient R(1 , X) and the coefficient of weak orthogonality omega(X). Some known results are improved and strengthened.
