The merits and demerits of frame differential method in motional detecting were analyzed and optimized. 詳細討論了運動(dòng)檢測中幀差法的優(yōu)缺點(diǎn)，并設計了快速實(shí)現算法，同時(shí)提出了對原有方法的改進(jìn)。
The general eddy current flaw reconstruction strategy was the least-square error method, which required the forward solver having high speed. 在渦流檢測中，常利用最小方差法來(lái)進(jìn)行缺陷重構，這種方法要求正問(wèn)題的求解效率高。
