In order to maintain high vacuum in a cavity of MEMS devices, residual gases and leaking gases must be eliminated by embedded getter materials.
According to molecule kinetic theory and vacuum science and technology, the gas molecules can be expressed in PV number, where P and V are pressure and volume respectively.

The raw material of boiler mainly includes coal, heavy oil and coal gas, there were six main drawbacks by the way of this heating mode: (1) It can produce a large amount of waste gas and waste residue, which can result in the heavier atmospheric environmental pollution and waste of electricity; (2) due to adopting the high power blower and induced draft fan, the electricity consumption was very high (3) Because the special man was needed to maintain the boiler，it can result in waste of manpower and financial resources; (4) There were other drawbacks，such as the complex installation and maintenance; (5) Using the desulfurization and the removal equipment of dust can increase the investment and spending; (6) Due to the flame combustion, a huge hidden trouble was produced when the leakage happened.
