摘要
从物理和数学的角度讨论了一些在第二型面积分的教学中遇到的问题,通过讨论可消除学生在学习这部分内容时有关不可压缩流体的误解,并完善一些教科书的相关表述.
Some problems encountered during teaching of integral over oriented surface are discussed from both physical and mathematical point of view. This discussion will clarify students＇ some misunderstandiing about incompressible fluid during study of this content and improve the related explanation of some textbooks.
