primary ionization meaning in Hindi

Examples

1. On passing through the detector gas, a particle will produce primary ionization along its track.
2. In a major distinction from chemical ionization, the electrons needed for the primary ionization are not produced by a heated filament, as a heated filament cannot be used under atmospheric pressure conditions.
3. Even though, theoretically, it seems as if M can increase without limit ( exponentially ), physically, it is limited to about M 8 or ?x < 20 ( where ? is the first Townsend coefficient and x is the length of the path of ionization, starting from the point of the primary ionization.
