摘要
数码显微、延时摄影等数码技术可以应用于铁的吸氧腐蚀实验,帮助学生观察细节现象及变化过程。在"探究海洋工程中钢管桩腐蚀速率曲线的奥秘"的教学中,数码技术支持下的吸氧腐蚀实验,能促进学生构建供氧均匀和供氧不均匀2种吸氧腐蚀认知模型,达成教学目标。
Digital technology such as digital microscopy and time-lapse photography can be applied to the oxygen absorption corrosion experiment of iron to help students observe the detailed phenomenon and change process.In the teaching of"probing into the mystery of corrosion rate curve of steel pipe pile in ocean engineering",oxygen absorption corrosion experiment supported by digital technology can promote students to build cognitive models of uniform corrosion and local corrosion,so as to achieve the teaching objectives of the subject.
