摘　　要：利用两两NQD(negatively quadrant dependent)随机变量序列部分和的弱大数律和推广的Kolmogorov型不等式,得到了两两NQD序列部分和之随机和的弱大数律,获得了与独立同分布情形相类似的结果。The weak law of large numbers for random sums of partial sums of pairwise NQD sequence of random variables is obtained by the weak law of large numbers for sum of partial sums and extended Kolmogorov-type moment inequality of pairwise NQD sequence. The available result corresponds to the result of independent and identically distributed sequence of random variables.
