Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 4314-2000 "getter term", compared with the GB/T 4314-2000 main technical changes are as follows.
--- Of high temperature getter, high fastness getter, terminal breathing rate, specific absorption capacity, deflation, total deflation, pre-deflation
Quantity, mercury release rate, mercury release getter thermal stability terms such as the name, the definition re-explained;
--- Added combination of getter (3.40), low temperature amalgam (3.41), the initial inhalation rate (4.16), free mercury (4.66) terms.
This standard proposed by the Ministry of Industry and Information Technology of the People's Republic of China.
This standard by the China Electronics Standardization Institute centralized.

Getter terminology
1 Scope
This standard defines the general terms of getter, classification terminology and terminology.
This standard applies to vacuum devices with getters.
2 general terms and definitions
2.1
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.
