Virtual experiment can improve the students’learning enthusiasm and ability to promote the reform and development of higher education under the background of emerging engineering education disciplines．However，the virtual experiment teaching system was short of its own independency and completeness，its teaching methods were lack of independence and innovation，and its teaching contents were also lack of

practicality．So that the sustainable development of its virtual teaching was blocked．In this work，the“2+3+1” virtual teaching mode is suggested through internet and virtual simulation according to characteristics of specialty experiment． Its teaching contents，teaching methods，teaching implementation，and teaching evaluation are structured． It has showed that 92% student think this virtual teaching mode could improve learning initiative，and help them to effectively control learning process through“Virtual simulation experiment on fault diagnosis ＆ startup and shutdown of kiln system”．At the same time，it also may help them to develop a good habit and attitude of learning，gain a sense of achievement，and enhance self-confidence in order to improve the average retention rate of learning．
