Our version is different from your's. I wonder if the exercises in the after-class experiment will be the same. You can download it from amber after-school resource network, where we can enjoy the latest experimental report. Important students can also download from our forum, the address is my name, hehe. But out of date, Tsinghua version and traffic version.

I sent it, check it! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
