本文利用修正的弱Galerkin方法求解第一类变分不等式，包括Signorini问题和障碍问题。最佳顺序的先验误差估计的能量范数。我们还提供了一些数值实验来验证理论结果。Numer Methods Partial Differential Eq 33：1459-1474，2017
In this article, we apply a modified weak Galerkin method to solve variational inequality of the first kind which includes Signorini and obstacle problems. Optimal order a priori error estimates in the energy norm are derived. We also provide some numerical experiments to validate the theoretical results.© 2017 Wiley Periodicals, Inc.
