1. This paper establishes a global attractor of hemigroup produced by the initial boundary value problem of generalized convection and expansion equation.
   从动力系统角度,建立了广义对流扩散方程初边值问题所产生半群的一个全局吸引子。
2. It proves that the posterior probability about experiments makes up hemigroup then proves that the posterior probability of the order experiments and the accumulation experiments are the same.
   证明了后验概率关于试验构成半群,从而序贯试验与累积试验具有相同的后验概率。
