摘　　要：弱鞅是一类较为广泛的相依序列,并且均值为零的PA序列部分和序列也为弱鞅,同样可以推广到条件弱鞅.所以研究弱鞅的不等式很重要.本文将重点研究弱(半)鞅以及非负弱鞅的极小值不等式.并在此基础上得到了一些改进.As we all know,Deminartingales as a special kind of random variable sequence,and the partial sums of sequences of and mean zero are independent random variables,and mean zero associates random variables.It＇s important to research Deminartingales inequality.In this paper,some minimal inequalities of demi（sub）martingales and nonnegative demimartingales are established.

关 键 词：条件弱鞅 弱鞅 极小值不等式
