提出了一种新的特征有限元格式，它具有时间增量二阶精度、对称且无条件稳定。最优误差估计在理论框架中得到证明。给出了两个例子的数值结果，显示了该方案的优点。
A new characteristic finite element scheme is presented for It is of second order accuracy in time increment, symmetric, and unconditionally stable. Optimal error estimates are proved in the framework of-theory. Numerical results are presented for two examples, which show the advantage of the scheme.
