introduction： High purity noble gases usually contain0.!%Of active gas impurities，This purity is equivalent to133PaVacuum of...。This gas is used to protect metals from heat，It still reacts with the metal surface，So further purification is needed，From the point of view of the cost of purifying and maintaining purity，To make the impurities reach1×10-6The following is very difficult，while1×10-6The residual gas is only equal to1.33×10-1PaVacuum degree，This vacuum is mechanically pumped+The Roots pump can be achieved with a longer time。The cost is much cheaper than cleaning the gas to the same degree。 （
