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.
通过采用预测校正二步时间积分和单元内引入坡度限制，该算法在时空上均可达到二阶精度。
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.
