摘　　要：二行动线性决策问题是一类重要的决策问题.文中讨论了在期望μ已知,方差σ2未知的情况下,(IGa-N)模型下的二行动线性决策问题的抽样信息期望值的计算公式.The linear decision problem on two actions is a class of important decision problem. This paper presents the calculation formula of EVSI for the linear decision problem on two actions under the （ IGa - N） model as the desireμ is known and the variance σ^2 is unknown.
