second-order accuracy

基本解释

Second-order accuracy both in time and space can be achieved by means of an explicit predictor-corrector scheme and slope-limiting within elements.
通過採用預測校正二步時間積分和單元內引入坡度限制，該算法在時空上均可達到二堦精度。
An implicit flux vector splitting form in one-step with second-order accuracy was proposed for solving the transonic flow fields of air channels and cascades of diffusers.
