3、ability in terms of teaching, research,can be used for the practical teaching of professional courses to improve the conditions of the experimental teaching to meet the needs of professional teaching. The experiment, the mainstream temperature at room temperature, stream 100 , the mainstream speeds

4、of up to 100 m / sec, student test section of hot runner cross section 4 2.5cm. Research and test section flow channel cross-section of 20 10cm. The buffer tank contraction can accelerate airflow, and flow field to maintain a good quality. The purpose of the task is to design from the gas source to the buffer tank of cold, hot runners, throttle experimental setup to explore the muffler noise reduction and other issues.
