Question on variable definitions in Paschens law? (breakdown voltage)

[Krejuski]

Hello all,

In the equation V= apd/Ln(pd)+b as described by Paschens law regarding breakdown voltage, I was wondering what the "L" and the "n" stood for. Example of what I'm looking for: p stands for pressure.
Thanks.
