The equation is discretized by discontinuous Galerkin finite element method, that is approximating functions being discontinuous at the nodes of partition in time.
利用间断时空有限元方法对方程进行离散，即允许近似函数在时间节点处是间断的。
To the best of my knowledge, it seems that it is the first time to apply the local discontinuous Galerkin method to the stochastic elliptic equation.
这类不连续数值方案被应用到随机椭圆方程中好像还是第一次。
