Lastly, the demagnetizable method to high-speed moving steel pipe is researched and the discrete time method is used to explain the demagnetizable processing of steel pipe.

提出了采用時間上離散化的退磁過程分析方法，很好的解釋了鋼管的退磁過程，解決了鋼管高速運(yùn)動中的退磁問題。

MFL signal process systems and online demagnetizable equipments used in foreign testing equipment are developed on the basis of these researches and applied widely.

在上述研究的基礎(chǔ)上，研制出適用于國外設(shè)備的漏磁信號處理系統(tǒng)及鋼管在線退磁裝置日韩人妻无码免费视频一二区色，取得良好的應(yīng)用效果。
