#Follow Longzhong across the sea: Beijing Public Research Unit part-2

"Vacuum", a state of space defined as "the absence of any matter", is a physical phenomenon. The fewer particles, the more vacuum, and the vacuum tube used in this case must have a vacuum of 1×10−5Pa to 1×10−8Pa .
So how do you make it a vacuum? Let us introduce you one by one here!
