摘要：
A two-field mixed-hybrid spectral element formulation in time and space is presented. Explicit (STSEE) and implicit (STSEI) algorithms are developed and used to solve a second-order scalar hyperbolic equation. The algorithms were analyzed and their characteristics in terms of truncation error and stability are presented. This analysis was confirmed by numerical results. The improvement in accuracy in comparison with semi-discrete schemes is remarkable.
