The stable and unstable seepage flow of gas can be briefly related because it is very similar with single-phase fluid seepage flow law (only pressure and pseudo tEk/pressure, time and pseudo time are different). Very few sections in this chapter need to adopt computer and multimedia to teach students Writing design on blackboard: Formula is more in this chapter, so it needs to be made clear which is fundamental formula, and which is general formula importance formula are tun fa marked out by red chalk, write on the left or middle side of blackboard, The right side of 出,难点 blackboard takes as the place to write temporary draft 如何解 Difficult point solving: By the detailed derivation of the fundamental formula and Intercommunication between teacher and students: inquest by illumination, one man or 互动等 colony answer Why need to introduce the concept of pseudo pressure and pseudo time? 和习题 Exercises5-3、5-4. 参考资料 Refer to reference book in the first page of this teaching plan 备注 The content of this chapter are relatively simple, during the course student should be noted to Combine the content with single-phase fluid seepage flow law related before
