According to the requirements of commissioning and experiments,the vacuum systems of SFC,SSC,beam lines and four subsystems of CSR opened to the air for more than 40 times in 2008. The vacuum degree renewed to the required target rapidly every time. Even if for the CSR vacuum chambers which need to be baked-out,only 3～5 days were needed to get the pressure from atmospuere down to 10-8 Pa.
