本文考虑一类定义为分数阶随机热方程均方解的时空随机场模型。针对完全参数化时空随机场的估计问题，引入了空间和时间上的不同采样方案。
In this paper, a class of spatiotemporal random field models defined as mean-square solutions of fractional versions of the stochastic heat equation are considered. Different sampling schemes in space and time are introduced to solve the problem of estimation of fully parameterized spatiotemporal random fields.
