Getter terminology1 ScopeThis standard defines the general terms of getter, classification terminology and terminology. This standard applies to vacuum devices with getters.2 general terms and definitions2.1 Gas volume gasquantity An ideal gas in a statistically equilibrium state has a kinetic energy measure equal to the product of the volume occupied by the gas and its pressure. Note. If necessary, indicate the gas temperature or the value in liters at 20 ° C (Pa · m³), or coke (J). 2.2 Adsorption phase molecule adsorbedgasmolecule Gas molecules that have adsorbed on a solid surface. 2.3 Gas molecule gasmoleculeinspace Corresponding to the adsorbed phase molecules, gas molecules on the gas side at the gas-solid interface. 2.4 Flow rate throughput Qt The amount of gas passing through a section within a unit of time. The unit is Pa [Sika] cubic meters per second (Pa · m3/s). 2.5 Leakage rate leak-uprate Increased amount of gas per unit time due to leak or deflation in the system. The unit is Pa [Sika] cubic meters per second (Pa · m3/s). 2.6 Adsorption adsorption The getter or getter film surface on the gas or vapor capture phenomenon. Note. More specifically, "surface adsorption." 2.7 Absorption absorption Gas or vapor diffuses into the getter or getter film inside the phenomenon. 2.8 Inhale sorption Due to adsorption and absorption phenomena caused by the gas and steam removal process. 2.9 Desorption desorption Gas absorption phenomenon. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 4314-2017_English be delivered?Answer: Upon your order, we will start to translate GB/T 4314-2017_English as soon as possible, and keep you informed of the progress.
