小偏差概率估计问题的研究历史悠远,从Chebyshev到Stieltjes[1],提出了切比雪夫不等式并给出了证明过程.后来Karlin S[2],Isii K[3]在概率的研究工作上也做出了非常杰出的贡献.近期,Popescu I[4]得到了单峰分布下随机变量在时,的上确界.在国内,也有相关研究[5-8],这些研究使概率理论的应用价值得到了非常广泛的推广.

Supposed random variablesis the unimodal distribution.Modeand the random variableswith,,mainly studied the problem of estimating on upper bound and lower bound of probability for three-piece truncated random variables for estimations ofwith,given.Gave the estimates on bounds of probability for three-piece truncated random variables of the unimodal distribution,the result improves the original understanding of probability theory.
