英文摘要：

Let{ξn,n≥1}be a strictly stationary and negatively associated sequence with mean zeros and Eξ12〈∞ and 0σ^2=Eξ12＋2∑k=2∞Eξ1ξk〈 ∞.Let Sn = ∑ k=1nξk,Mn=∑ k=1n｜Sk｜,n ≥1.Using the central limit theorem and the probability inequality of negatively associated（NA）sequence,the authors obtained the precise rate in the Chung law of logarithm of NA sequence for more general boundary function and weighted function.
