townsend coefficient वाक्य

उदाहरण वाक्य

1. He made precise measurements of Townsend coefficients and cathode voltage fall.
2. This is also known as the second Townsend coefficient.
3. Powell's kinetic theory calculation found that the ball size is set by the second Townsend coefficient ( the mean free path of conduction electrons ) near breakdown.
4. Assuming that \ Gamma _ { i } ( d ) = 0 one gets the relation between the Townsend coefficients by putting ( 4 ) into ( 3 ) and transforming:
5. Per length of path x a number of \ alpha ionizations will occur . \ alpha is known as the first Townsend coefficient as it was introduced by Townsend in, section 17.
6. The " first Townsend coefficient " ( ? ), also known as " first Townsend avalanche coefficient " is a term used where secondary ionisation occurs because the primary ionisation electrons gain sufficient energy from the accelerating electric field, or from the original ionising particle.
7. 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.
