本文提出了一种求解非线性动力学问题的有效的时间间断Galerkin方法。该过程是基于一个廉价的迭代算法，这是相当不同于以前的努力。事实上，该算法的设计，使校正的解决方案继承所需的稳定性和耗散性能和迭代只用于提高精度。一些数值试验表明，本程序的良好性能，这似乎是有竞争力的时间不连续Galerkin方法的现有实现。
This paper presents an effective time discontinuous Galerkin procedure for non-linear dynamics. The procedure is based on a cheap iterative algorithm, which is rather different from previous efforts. In fact, the algorithm is designed so that the corrected solutions inherit the desired stability and dissipative properties and the iterations serve only to improve accuracy. Some numerical tests illustrate the good performance of the present procedure, which appears to be competitive with the available implementations of time discontinuous Galerkin methods.
